0:12so okay so we talked a little bit about
0:15motivation last time or quite a bit
0:17about motivation and what I I told you
0:20that I was basically teach you teaching
0:23you a personality Neuroscience approach
0:25to personality and um part of the reason
0:28that I have to go into the bi ology to
0:31give you is to give you the kind of
0:32foundation that you need in order to
0:34understand I would say what's
0:36essentially The Cutting Edge in
0:37personality research you know I mean I I
0:41know that what we're going what we
0:43covered last lecture and what we're
0:45going to cover today are relatively
0:47complicated but if you get them right
0:48then you're right at the Forefront of of
0:52of our ideas about brain function and
0:54emotion and about personality so you get
0:57all that at the same time and today
0:58you'll get a little bit of learning
1:00Theory thrown in as well so learn
1:02learning theory is basically what used
1:04to be what's what's alternatively
1:06described as behaviorism and I don't I
1:09used to teach behaviorism in this class
1:11but I've subsumed it underneath the
1:13biology because the old a lot of the old
1:15behavioral presuppositions although they
1:17were extremely useful were not right is
1:21which is exactly what you'd expect they
1:23were formulated in the
1:241950s um and it's actually the sign of
1:27the progress of a science that theories
1:29that are 60 years old are no longer
1:31right
1:33so um we'll also cover a little bit of
1:36Behavioral Theory today too so okay so
1:39the hypothesis we've been working on so
1:41far or we'll call it the working theory
1:43is that motivations set goals or more
1:46accurately that they Define a conceptual
1:49space within which you perceive the
1:51world and within which you act towards
1:54some goal and or to some end point and
1:57the end point in some sense is specif by
2:00the motivational system it's a
2:02hypothalamic system often but not always
2:05but not only is the goal specified but
2:08the the underlying motivational systems
2:11also tune your perception so you're only
2:13looking at the things that you know to
2:15be relevant to the pursuit of that goal
2:17and they also either disinhibit or
2:20activate the behavioral schemes that you
2:22would normally use to pursue the goal
2:24and sometimes those or let's say the
2:27motor schemes because that would be more
2:29accurate when you think about Behavior
2:30you tend to think about voluntary
2:32Behavior but a motivational state will
2:36disinhibit or activate depending on the
2:38situation autonomic responses so for
2:40example when you when you're food
2:43deprived and you start to think about
2:45food and start to organize your behavior
2:47towards food as an end and to perceive
2:50the world that way your body also
2:51prepares for food and so the
2:54motivational state is an
2:55all-encompassing psychophysiological
2:58phenomena it's not something as simple
2:59as chain Behavior which was an early be
3:01behavioral Theory or as simple as
3:05something that's merely setting a goal
3:06it's much more complicated than that
3:08it's it's useful to think about as we've
3:11already talked about with regards to
3:13psychodynamic Theory it's useful to
3:15think about a motivated State as a micro
3:17personality I mean it's it's got one aim
3:20in mind fundamentally so it's it's not
3:22particularly sophisticated but it has
3:24all the other elements of a personality
3:26so now so motivation establishes the
3:30framework within which goals are pursued
3:32and the goal itself and then roughly
3:35speaking emotions or at least many of
3:38the emotions track progress towards
3:40goals and so they kind of tell you
3:42whether you're on the right track or not
3:45so that's a reasonable way of of
3:47distinguishing them even though there is
3:49no single motivation system or single
3:51emotion
3:53system here's some basic
3:56motivations um these are the sorts of
3:58things that Freud would have ass
3:59assciated fundamentally with the ID so
4:02and he thought of those as primordial
4:04and that's exactly right because pretty
4:06much all of these motivational systems
4:08we share certainly with other people
4:11also with other mammals and then of
4:14course with animals that are farther
4:16down the evolutionary chain than mammals
4:18so some of these systems are
4:19extraordinarily old in fact all of them
4:21are extraordinarily old Hunger
4:23consequence of food deprivation
4:25obviously thirst obviously people are
4:28very dependent on water
4:30um pain Pain's complicated there's
4:34there's physical pain and then there's
4:38it's mental equivalents and the mental
4:40equivalents of pain are
4:43grief
4:45disappointment frustration roughly
4:47speaking and so you can the way you can
4:49think about that is you you know you saw
4:51the picture of the nervous system that I
4:52showed you last time with the branches
4:54going up into the brain obviously but
4:56with all the branches or the roots say
4:58going down into the body so we discussed
5:00the central nervous system as a sort of
5:03all-encompassing system distributed
5:05throughout the
5:06body imagine that part of that Network
5:09throughout your body is associated with
5:11pain reception and that would be roughly
5:13equivalent to systems registering levels
5:17of input that are high enough to
5:19potentially damage them that's that's
5:21where pain seems Seems to come in and
5:23that different pieces of that can be
5:25activated at different times so if it's
5:28psychological pain as I said grief
5:30frustration disappointment seems to fall
5:32into that category uh loneliness is
5:35another one um then maybe it's primarily
5:39the cortical circuitry for pain that's
5:41activated and although people who are
5:43depressed for example or who are
5:44grieving often have somatic pain as well
5:47and depression really looks like it's a
5:49pain State um we know loneliness is
5:52because if you take like little chicks
5:54or little kittens and you make them
5:56Lonesome and they'll cry you know which
5:58is a or or or peep if they're chicks and
6:01you can stop them from doing that by
6:04using
6:05opiates and uh it's not because it stops
6:08them from vocalizing because that would
6:09be a possibility just get them so stoned
6:11on you know morphine that they can't
6:13Peep and you think well they're now
6:15they're they're not Lonesome anymore so
6:17it's the experiments have been done
6:18carefully enough to factor out the
6:21effect of the opiates on the
6:22vocalization so and that's also led to
6:25some suspicion that people who
6:28have have had a a history of
6:31extraordinarily painful personal
6:32relationships might be those who are
6:34more prone to opiate use and so opiates
6:38analgesics are they basically dampen out
6:41pain and frustration and disappointment
6:43and grief and loneliness so there's an
6:46anger and aggression system it's
6:48complicated there's probably two of them
6:50one is defensive aggression that's
6:52probably more associated with
6:54neuroticism technically the other is
6:56probably predatory aggression and you
6:59know human beings are definitely
7:01Predators we're meat eaters and you know
7:03uh our closest relatives chimpanzees for
7:06example they're they're pretty good
7:07Hunters um they they'll they all pack
7:11gather together in packs and bring down
7:1230 PB cbus monkeys and and the meat is
7:15very popular Among The Chimps and so
7:17predatory aggression seems to be a
7:19separate circuit and as we'll discuss
7:21further along I think the predatory
7:23aggression circuit and the maternal
7:25solicitude circuit because there's also
7:27a Care Circuit have evolve to be at
7:30opposite ends of the same distribution I
7:33think that's the agreeableness
7:34distribution in the big five so on one
7:36end there's maternal solicitude and the
7:38other end there's predatory aggression
7:40and you can imagine how those things
7:42have to inhibit one another
7:45um because well with with many mammals
7:48bears for example the the males are so
7:51predatory that you have to keep them
7:52away from the Cubs because they'll kill
7:54them the human beings I mean there's
7:56some aggression towards children
7:59especially if the children aren't
8:00biological relatives but men are pretty
8:03caring for male mammals and and women
8:05are actually quite predatory for male
8:08mammals so thermal regulation your
8:10hypothalamus takes care of whether
8:12you're hot or cold panic and Escape th
8:16those are circuits that also seem to be
8:18associated with with pain fundamentally
8:20although threat can maybe trigger them
8:22as well and the Panic Escape system
8:24doesn't exactly seem to be the same
8:26system as the anxiety and fear system
8:29even though they sound they sound
8:31roughly equivalent right you might think
8:33of panic as just the extreme level of
8:36fear and I think fear can trigger panic
8:38but Panic seems to be a more primordial
8:40circuit and if you're panicking there's
8:42an immense impetus to to escape so
8:46that's a different circuit affiliation
8:48and care we covered sexual desire
8:51exploration and play both of those seem
8:53to be separate circuits so Jack PP Yak
8:55pep actually who wrote a great book
8:57called affective neuroscience by the way
8:59if any of you are interested in like the
9:02psychobiology of behavior and motivation
9:05Yak Pep's book is one of the best we I
9:07don't have a paper by him in in our
9:09collection but he's a very smart guy he
9:12wrote this book called affective
9:13neuroscience and it's actually given its
9:16title and the relative complexity of its
9:18of its thoughts it's actually quite
9:20readable even though it's a text it's a
9:22little more personal than your typical
9:24text might be and PP is also very
9:26interested in uh psychodynamic
9:29personality idea so he's a very broad
9:31thinker and so if you're interested in
9:34you know an approach to psychology that
9:36sort of crosses the threshold from
9:38personality into emotion and biology
9:41panp as well as gray there's a gray
9:43paper that you're reading are Pep's a
9:45very very good source he's a
9:48very he discovered the play circuit for
9:51example um and he also discovered that
9:55rats
9:56laugh so if you tickle rat it laughs you
10:00can't hear it though because it it
10:02laughs ultrasonically like a bat but if
10:04you record the rat giggling and then
10:08slow down the tape then you can tell
10:10that the rat laughs and rats need to
10:12play and most mammals need to play in
10:14order to uh socialize them so so one of
10:18the things you can think about this when
10:19you're parents too and this is probably
10:20especially relevant for the men because
10:22one of the things you might ask is what
10:24role do men play in the socialization of
10:26children and one thing that men really
10:28do seem to do with kids is to engage in
10:30rough and tumble play especially once
10:32they're a little older than two say 2 to
10:345 or something and kids love that they
10:36absolutely love rough and tumble play
10:39gets them so excited that you know they
10:40get out of control fundamentally but
10:43Rough and Tumble play is an excellent
10:45mode of socialization because it teaches
10:47the child the the distinction between
10:50aggression and too much aggression right
10:53because if you're wrestling with a kid
10:55the kid has to keep their behavioral
10:58output under a fair degree of control to
11:01keep the game going to make it rough
11:02enough to be exciting but not so rough
11:04that they get hurt or you know that they
11:06stick their thumb in their dad's eye or
11:07something like that and you you can
11:10think of that from a pedian sense too
11:12because it's a game but imagine that if
11:14you're trying to figure out how to
11:15configure yourself around other people
11:18if you haven't had that Rough and Tumble
11:20play you don't really know where the
11:22boundaries of your body are you know and
11:24and you don't know how much you can take
11:26and how much you can be stretched and
11:28how much you can be thrown around and
11:30when something actually hurts rather
11:33than is frightening and so all that
11:35intense sort of play that that um that
11:38boys in particular are likely to engage
11:40it although girls also like it um seems
11:43to be very useful for teaching children
11:46about how to engage with the world but
11:49and with other people in a physical way
11:51and that's one of the physiological
11:52foundations for higher order
11:54socialization so it's very useful I mean
11:57I've I've often noted that children who
11:59haven't had the opportunity to engage in
12:02physical play they're kind of awkward
12:04you know they they're not they're not
12:05seated well in their body and it's like
12:07they're kind of vague physically whereas
12:10the ones who've been twisted around and
12:12bent and thrown up in the air and you
12:14know wrestled in general they're a lot
12:16more conscious of their limits and their
12:19abilities in their body and they're also
12:21much more able to invite other kids to
12:24play you can think about this with
12:26regards to dogs you know if you have a
12:28dog you know the dog you can tell when
12:29the dog wants to play right what does
12:31the dog
12:34dos around yeah it jumps around and it
12:37puts its rear end in the air often and
12:39its head down and it looks up which is a
12:41little bit submissive and a little bit
12:44friendly and it wags its tail and it
12:45might bark and it moves back and forth
12:47and like little kids that want to play
12:49do well they don't put their tails in
12:50the air obviously but they they they
12:53they engage in like play invitation
12:55behaviors like that you know little bit
12:57of teasing sometimes and they're trying
12:59to get some play initiated um it's also
13:02practice for later dominance um when
13:04chimps play the males in particular as
13:08they approach adolescence the play
13:09Behavior because they'll all they'll
13:11throw sticks at the old chimps who are
13:13laying down and sleeping or come up and
13:15poke them or you know tease them and
13:17then as they become more and more
13:19powerful and more and more adolescent
13:21say into adulthood then that play will
13:23become full-blown dominance challenges
13:26as you don't no doubt noticed if you
13:28were in junior high high school because
13:30that's exactly what happens to teachers
13:32right the little elementary school kids
13:33they're kind of cute when they misbehave
13:35they're sort of playful but by the time
13:37grade eight or grade nine comes around
13:39the pushing on the teacher is a lot
13:41harder and so you can see how play
13:43Shades into dominance dispute but it is
13:46a separate circuit exploration that's a
13:48separate circuit and one of the things
13:50that we'll talk about today is Swanson's
13:54elaboration of the fact that half of the
13:56hypothalamus is fundamentally devoted
13:58towards exploration which is quite cool
14:00it means exploration is a really really
14:02really old system and it's sort of like
14:06if you haven't got anything else to do
14:08so you don't want to play you're not
14:09hungry you're not thirsty you're not
14:12angry you're not too warm or too cold
14:14etc etc your default isn't sort of
14:18quiescent sleep right you don't
14:21just run out of batteries and lie on the
14:24floor unless you're of course obviously
14:26unless you're very tired what'll
14:28generally happen is the other
14:29fundamental motivational states have
14:31been satiated then you'll engage in
14:34Exploration and some different people at
14:37different rates if you're extroverted
14:39you'll engage in exploration in the
14:42social environment and if you're open
14:44then you'll engage in Exploration at a
14:46more cognitive level so that would be
14:48with regards to artistic creativity or
14:50to fiction or or the expression of some
14:52sort of intellectual or philosophical
14:54Pursuit and the reason that you're wired
14:56up that way is because if you have a
14:59little extra energy you might as well
15:01use that to map out more of the
15:03environment so that when push comes to
15:06shove somewhere down the road you'll be
15:09in possession of more information and
15:12more flexible and more knowledgeable in
15:14your in your in your conceptual and
15:17perceptual structures and also in your
15:19actions so people have a pretty strong
15:21tendency to default to exploration but
15:24there's variability in that um you can
15:27also sort of divide up these motiv ation
15:29as ingestive or defensive that's not a
15:31bad way of looking at it and then
15:33there's reproductive motivations as well
15:35that's unlikely to be a full map it kind
15:41of depends on where you put the emotions
15:43because we know for example that there's
15:45a separate disgust circuit and that
15:47doesn't seem to load with anxiety or
15:49with pain it's it's it's its own
15:52biological um system and and it seems to
15:55be associated with trait
15:57conscientiousness Maybe and also with
16:00political conservatism and orderliness
16:02so those things are all quite
16:03interesting they all kind of Clump
16:05together and but whether that's an
16:07emotion or motivations not exactly clear
16:10but um we'll talk about a little bit
16:13more so there's the
16:14hypothalamus and as you can see um it's
16:18not one thing of course nothing at the
16:22macro level in the brain is one thing
16:24obviously it's this layered thing just
16:26like everything else in the world except
16:28even more so because the brain is so
16:30incredibly complicated and you can see
16:31by looking at that there's all those
16:33little all the things that are colored
16:35there
16:36basically hypothalamic um modules I
16:40guess would be a reasonable way of
16:42putting it and you can tell they're even
16:44an anatomically distinct so obviously
16:46they're not doing exactly the same thing
16:49so you might think of brain anatomy as
16:52sort of a
16:53fixed what would you call something that
16:55we've already managed quite well and we
16:57have all the category systems down and
16:59the structure of the brain is quite well
17:00known and that's really not true at all
17:03like the brain is truly Terra incognita
17:05and it isn't even like our naming uh
17:08rituals let's say or
17:09conventions are not necessarily
17:12appropriate for onetoone mapping of say
17:14structure onto function so um they're
17:18they're they're sort of anatomical
17:20they're markers for anatomical
17:21convenience in some
17:23ways okay so so here's a way of thinking
17:26about it so you have your frame
17:29which specifies your lack say I'm hungry
17:32and then a goal pops up which is well I
17:34should have something to eat and the
17:36hypothalamus is modulating perceptual
17:39and cognitive circuits so that you think
17:41that and so that you start to parse up
17:42the world into a place where a hungry
17:45person like you could become satisfied
17:49and then the behaviors kick in that are
17:52relevant to that um Pursuit and so you
17:56can think of yourself as popping through
17:59these sorts of frames on a fairly cyclic
18:02basis throughout the day you know
18:04obviously you get hungry you get thirsty
18:06you get tired and so your Consciousness
18:08is being modulated by subcortical
18:12circuitry that is basically charged with
18:16your
18:16self-preservation and in some ways you
18:18come along for the ride I mean your
18:20Consciousness is mostly there in some
18:22sense to detect deviations from not so
18:26much expectation but from desire right
18:29cuz you lay out one of these little maps
18:30on the world and then you want something
18:32to happen and what your Consciousness
18:34does more or less is Mo Monitor and if
18:39something that you don't want to happen
18:42happens then Consciousness will take a
18:45look in some sense remember that
18:47hierarchy of goals that I showed you
18:49from you know motor output up to high
18:52order goals your Consciousness kind of
18:53moves up and down that thing if if
18:56you've made an error trying to figure
18:57out at which level of abstraction that
19:00error should be rectified which is sort
19:02of what you do when you think and so
19:05that process is going to kick in
19:07whenever you're moving towards your
19:09desired end and something that you don't
19:11want to have happen happens right you
19:13usually stop that sort of an an anxiety
19:15response the stopping and then if
19:19nothing else happens that's too bad well
19:21then you'll you'll start to explore
19:23animals often do that by moving around
19:25but people will do that just as with
19:28with equal facility just by running
19:31simulations in their mind and trying to
19:33calculate what went wrong right trying
19:35to think about it that's a form of
19:36exploratory Behavior as well that would
19:38be more associated with trait openness
19:40and with
19:41intelligence
19:45so so there's how um Swanson divides up
19:49the hypothalamus see the uh little pink
19:53things there on the left are part of the
19:56defensive circuits and then the red
19:58things on the left are part of the
20:00reproductive circuits and you know
20:03obviously those the fact that those
20:05circuits exist lays onto darwinian
20:08Theory quite nicely the defensive
20:09circuits obviously protect you from
20:11dying and the reproductive circuits you
20:13know facilitate your reproduction it's
20:17not much of a what fairly obvious
20:22conclusion and so those are all you
20:24located in this in this you know
20:26essential part of the brain the the
20:28hypoth
20:29hypothalamus
20:31now this is something a little that's a
20:33little more complex so I'll go through
20:35it a little bit more carefully so if you
20:36look on the right this is where Swanson
20:40Maps perfectly
20:42onto p and I I put this Swanson paper in
20:46as a optional reading but if you're
20:49interested in the sorts of things that
20:50we're covering this class that's a great
20:52paper to hack your way through even
20:54though it's very hard because you you
20:57learn a lot about
20:59the underlying biology of some of these
21:01more complex clinical and developmental
21:04theories that we've covered so basically
21:06what Swanson is pointing out is that at
21:09the lowest level at the highest
21:11resolution level of your central nervous
21:14system you're you're you have motor
21:18output circuits that are enabling you to
21:21move and those are communicating in
21:23large part with your spine but also with
21:26lower parts of your brain stem so those
21:27are fundamental movements of the sorts
21:29that P would call reflexive and then the
21:33locomoter pattern generator I think the
21:36best way to think about this from an
21:37analogical perspective and actually
21:39Alexander Lura used this
21:42analogy he called behavioral patterns
21:45kinetic Melodies it's a lovely phrase
21:48because you know how obviously a song is
21:50made out of notes and then the notes
21:51combined into phrases and the phrases
21:53combined sayanti passages and then well
21:56even more interestingly then if it's an
21:58chestal piece of music multiple
22:00instruments are playing at the same time
22:02so it sort of extends right into the
22:03social domain but your your actions are
22:06sort of like that they're made out of
22:07micro routines and then those are
22:09chained together and those are chained
22:11together in higher order abstractions
22:13and so on all the way up to the cortex
22:16and
22:18so Swanson points out that the the motor
22:23system has three sets of inputs so the
22:27cognitive system
22:29that sort of way up that's sort level of
22:31abstraction that's way up in the brain
22:33so the cognitive system is where you
22:35know you might do a voluntary action so
22:37you look at something you say well I'm
22:38going to pick up this piece of paper and
22:40so that's top down cortical control and
22:44then the state system input to the motor
22:46system the state system is your body
22:48monitoring what's going on inside of
22:51itself and the autonomic nervous system
22:54is part of the motor output system and
22:56so the state monitoring system takes a
22:59careful look and the hypothalamus does a
23:01fair bit of this takes a careful look at
23:02what's going on inside you and then
23:04activates different parts of your
23:06digestive and you know the the gut
23:08system fundamentally that that you have
23:10no conscious control over and then
23:13obviously there's sensory system inputs
23:15too so so those are the three main
23:18inputs into the into the motor system
23:20and that acts on the environment and
23:22then the motor system has this
23:24hierarchical nature that's built from
23:27the spine upwards so you can think of
23:30like the brain as a collection of ever
23:33expanding control systems that that
23:36allow you
23:38to what learn and undertake ever more
23:41complex motor schemes of action you know
23:43and one of the things that people think
23:45about human beings is that we're very
23:47good at thinking right but we're not
23:49just good at thinking like we're we're
23:51crazy crazily adaptable in terms of our
23:55motor output I mean if you watch the
23:57watch the Olympics
23:59you know and you you see human beings
24:01can do things that no other animal could
24:03even think of doing I mean we're
24:05completely crazy when it comes to the
24:06sorts of things we can do with our body
24:08like we're good on ice we're good in the
24:10water we can ski people are really good
24:13at jumping they can climb across
24:14buildings like people who train
24:16themselves can climb like mad I mean
24:19human beings are unbelievably variable
24:21in terms of their motor output so that's
24:22another part of our intelligence that's
24:24not just abstract and so in part that's
24:27because we have this
24:28very well-developed cortical area that
24:31enables us to chain ever more complex
24:34patterns of behavior together and also
24:36to develop patterns of behavior that are
24:38sort of outside instinctual
24:40specification so imagine with an animal
24:43that has a less complex brain a lot of
24:47its behavior is going to be limited to
24:49those quas instinctual patterns of
24:51behavior that are devoted directly
24:53towards the solution of basic biological
24:57problems but you know we can kind of
24:59solve those without too much effort and
25:00then we have all this spare motor
25:02capacity left over and people do the
25:03weirdest things with it you know and and
25:06really remarkable absolutely remarkable
25:10things so that's that's pretty cool
25:12we're pretty cool that way we don't get
25:15enough credit for it I don't think
25:16because human beings if think about
25:18human being as an animal which you know
25:20people are kind of loathed to do we are
25:21definitely the most interesting animal I
25:24mean if you saw like a what a pygmy
25:27hippopotamus skateboarding you'd think
25:29that was pretty remarkable you know but
25:31people they do those sorts of things all
25:33the time and you know we just take it as
25:35a matter of
25:37course the lowest somat motor neuron
25:39pools the lowest level of the locomoter
25:41system it's Locomotion and an action is
25:45formed by a subset of moto neuron
25:49tools that's wrong Moto neurons in the
25:52spinal cord ventral horn that innervates
25:54the limb muscles responsible for
25:56locomotor Behavior
25:59I dictated this with dragon dictate and
26:01now and then it does weird things say so
26:02tools God only knows where that came
26:04from
26:06so a set of motor neurons in the spinal
26:09cord ventral horn so it's way down in
26:11the spine that inate the Lum mus limb
26:13muscles responsible for locomoter
26:15behavior when you start to think about
26:16the brain as something that moves your
26:18body it's a lot easier to conceptualize
26:20the brain as something that's
26:21distributed through the body you know
26:23and your spine is actually quite smart
26:26so even though in some sense you don't
26:27think with it it's capable of very
26:30complex sensory detection and also motor
26:32mapping and so um
26:36mostly relatively automated and
26:38relatively reflexive one level up the
26:41existence of a spinal locomoter pattern
26:44generator so this shows that the spine
26:46isn't responsible just for the most
26:48basic of motor outputs or sensory inputs
26:50it can actually generate patterns is
26:52demonstrated by the fact that whereas a
26:54spinal animal displays no spontaneous
26:57locomotive activity so if you sever an
27:02animal its nervous system so it only has
27:05a spine it'll just lay there you know
27:07you'd think it's paralyzed that's what
27:09you would think
27:11but coordinated limb movements
27:13characteristic of locomotion may be
27:15elicited when the limbs of such an
27:17animal are placed on a moving treadmill
27:19thus providing sematic sensory input to
27:21the pattern generator and so they've
27:23done this with people who are paraplegic
27:25if you take someone who's paraplegic and
27:27so they can't obviously walk and you
27:29hoist them up and you put them on a um
27:32treadmill and you lean them forward
27:34their legs will walk and that's spinal
27:37controlled so that's what you're doing
27:39with your spine you know because you're
27:41not thinking when you walk or you're not
27:43thinking about walking unless you know
27:46unless you're one of those people who
27:47can't chew gum and walk at the same time
27:50so anyway so it just shows you how
27:52complex you are even at the you know the
27:55sort of the base levels of your of your
27:58intelligence hierarchy level up
28:01locomoter pattern controller so it's
28:03controlling
28:05the locomoter pattern
28:09generator in contrast undisturbed
28:11chronic hypothalamic animals okay so now
28:14one of the ways people figured out how
28:16the brain works was by sectioning
28:18animals nervous systems when they're
28:19alive at different levels of complexity
28:22so a spinal animal is one that's
28:23basically paralyzed its brain is
28:25separated from its spinal cord but then
28:27you can separate the
28:28hypothalamus with the intact spinal cord
28:31so it's one unit from the cortex and
28:34even from the memory systems and even
28:35from most of the emotion systems and so
28:38the animal in some sense hardly has a
28:39brain at all you know I mean the
28:41hypothalamus as you saw it's a little
28:43tiny thing and everything that's on top
28:45of that can be separated from it and the
28:47animal can um
28:50still act spontaneously so so here's an
28:54example if if this has been done with
28:56cats and if you have a female cat and
28:59it's in a cage and it's only a
29:01hypothalamic animal it can basically
29:04manage like it can't learn new things
29:07very well and it can't remember anything
29:10like it doesn't have episodic memory and
29:13so but it can it can maintain its
29:15temperature it can eat it can engage in
29:18sexual activity it's got defensive
29:20aggression like most of the animal in
29:22some sense is still there from an from
29:24an input output perspective um it's also
29:28hyper
29:29exploratory which is quite interesting
29:31he because you wouldn't think well
29:32animal with no brain is the most
29:34exploratory kind of animal well it
29:37happens to be the case as long as it has
29:38a hypothalamus so that shows you a how
29:41old exploration is but it also kind of
29:43gives you some clue about what the rest
29:45of the brain is doing I
29:47mean you you explore new things we'll
29:50say so what that means is you have to be
29:53able to tell the difference between
29:54what's new and what isn't and so what
29:56you need to tell the difference between
29:58what's new and what isn't is memory and
30:01so a lot of what the higher order parts
30:03of the brain are doing is basically
30:05keeping track of where you've been and
30:07so if you've been somewhere before then
30:10the exploratory circuit is basically
30:11shut off as long as everything that
30:13you're doing there is working and you
30:16need the whole brain basically to shut
30:18off the hypothalamus in some sense
30:20that's how the thing works it's like
30:22you're kind of a default on system you
30:25know your your motor systems are ready
30:27to go and you're kind of you're alive
30:29and you're ready to go like a wild
30:30animal but the cortex dampens that down
30:33and it does that by only allowing the
30:36activities that are relevant to that
30:37area that might be none of them to
30:40function at any one time so you take off
30:42the cortex while the animal can still do
30:44a lot of things but you know its ability
30:46to match Its Behavior to novel
30:48situations and to learn new behaviors is
30:50very very limited so it it becomes hyper
30:54exploratory but it can't remember
30:55anything and it becomes very limited in
30:58the flexibility of its behavior and so
31:00as you move farther up the hierarchy of
31:04complexity then you're able to do more
31:07and more novel and more and more complex
31:09and more and more situation specific
31:12things so in the sense of providing a
31:16certain level of endogenous activity
31:18which means self-generated activity so
31:20the hypothalamic animal will move by
31:23itself without being stimulated the
31:26hypothalamic Lo locomoter region can be
31:28thought of as a locomoter pattern
31:30controller which generates spontaneous
31:32inputs ultimately to the spinal
31:34locomoter pattern generator so there's
31:36there's
31:37hierarchy um I already talked about
31:39behavioral State inputs there's another
31:41picture of the nervous system just to
31:43remind you of how it looks um how it's
31:46distributed through the
31:48body oh this is very interesting too I I
31:52didn't learn this till I read this paper
31:53by Swanson I thought that's so dumb how
31:56could I've not learned that like 30
31:58years ago Swanson said that um let's go
32:02back one did I yeah rayon K was like the
32:05world's greatest neuroanatomist he was
32:07the guy who really established the field
32:09so did a tremendous amount of
32:11Investigation into the fine structure of
32:12the brain like 110 years ago a long time
32:16ago and he pointed out that sensory
32:19systems have a dual projection within
32:21the central nervous system I told you
32:23guys about Blindside already you know
32:24and the fact that your eyes map on to
32:27different LS of the hierarchy say of
32:29sensory input and motor control Kyle
32:31basically outlined the circuitry for
32:33that one branch goes directly to the
32:35motor system so it's that's for I to
32:38Output mapping So that's fast because
32:40there's not a lot of thinking in between
32:43and you might think that's bad because
32:45you want to think but it's good because
32:47sometimes you know what to do and you
32:48don't want to think you just want to
32:49execute it as fast as you possibly can
32:52so these lower order simpler inputs are
32:54good for that sort of thing one goes
32:56directly to the motor system and the the
32:57other goes more or less directly to the
32:59cerebral cortex where Sensations and
33:01perceptions are elaborated and voluntary
33:03motor impulses are generated so this
33:05sort of explains for a long time
33:09experimental Psychology was dominated by
33:11behaviorists who thought of the animal
33:12as a stimulus response machine and and
33:15never paid much attention to the
33:17function of things like thought or
33:19emotion or complex internal States and
33:22you know the behaviorists got an awful
33:24long way with their idea of the animal
33:26as a sort of simple stimulus response
33:28machine and that's partly because of
33:30this hierarchy that we're describing you
33:32know cuz you you can treat an animal as
33:35if it's a pretty simple machine because
33:37it has all that simple Machinery in it
33:40it's just that on top of that simple
33:42Machinery there's a lot more complex
33:44machinery and so but the simple
33:46Machinery does a lot more than people
33:47generally think and can do more than
33:49people think and so the fact that there
33:52are these at least two projections they
33:55Branch more than that gives you right
33:57away a sense of why the behaviors could
34:00have been right and the cognitive
34:01psychologist could have been right and
34:02even the psycho dnamic thinkers can be
34:05right because they're analyzing the
34:07system at different levels of
34:08hierarchical complexity and extracting
34:10out slightly different um what would you
34:14call uh observations and and some of
34:18these things are even the like the
34:20simpler systems can have quite complex
34:22outputs so so one of the things that the
34:24simpler sensory motor system does is
34:26detect snakes because primates don't
34:28like snakes in fact there's a a woman
34:31named
34:32uh Lynn Isbell wrote a nice book on
34:35primate Vision in snakes and she was
34:37very curious about why human beings
34:39could see so well and uh she also
34:41noticed that we're very good at
34:43detecting um the sort of camouflage
34:47patterns that snakes use especially in
34:48the lower half of our visual field and
34:50she did this cross-cultural survey
34:53around the world and found out that
34:56where there's more predatory snakes the
34:57primates have better Vision so we sort
34:59of co-evolved with snakes and snakes
35:02gave us Vision just like it says in
35:03Genesis which is pretty damn funny as
35:05far as I'm concerned and it was snakes
35:07and trees even so and fruit of course
35:10gave us color vision so the whole
35:12Genesis story nailed it pretty well but
35:15you know snakes have been around long
35:16enough and have been our enemy or say
35:18predatory reptiles you know if if you
35:20don't really want to go with the whole
35:21snake thing that are we've we've evolved
35:24we've coevolved with them it's like 60
35:26million years it's a very very long
35:27period of time so Darwin used to amuse
35:31himself in a darwinian way he'd go to
35:34the there was a a zoo or a a rep place
35:38that shows reptiles I don't remember
35:39what they're called but they had one
35:41glass cage where there was some kind of
35:43poisonous snake I think it was a cobra
35:44and Darwin would put his face right up
35:46against the glass and the Cobra would go
35:48whack and he'd jump back and he he did
35:52that many times because he was curious
35:54about whether or not he could actually
35:55bring the snake avoidance reflex under
35:58conscious control and he couldn't every
36:00time the snake jumped he'd jump
36:01backwards he couldn't control it and so
36:04that's because all the primates that
36:06could control it when there were snakes
36:08biting them are dead so it was Darwin
36:12was the beneficiary of the darwinian
36:14process in that in that sense so so the
36:17point is your body's conserved all these
36:19low-level fast operating circuits and so
36:22you're a simple machine and a sort of
36:24complex machine and an extremely complex
36:26machine and then some that's so complex
36:28that you can't even think about it as a
36:29machine and you're all those things at
36:31the same
36:33time and there's Swanson's take on how
36:36the motor system and the hypothalamus
36:38are integrated so it's quite nice he
36:40shows that the hypothalamic controller
36:43so that's one of the circuits that we've
36:45been talking about that are responsible
36:46for a basic motivated State get sensory
36:49input behavioral State input that's
36:51about the body and input from the
36:53cerebral hemispheres hypothetically
36:55that's thought or or voluntary action
36:59plan something like that and then it has
37:02output to the motor pattern initiator
37:04the generators and the motor neuron
37:06pools and then you act lovely it's very
37:09beautiful beautiful model and so you can
37:12see that it Maps very nicely onto that
37:14with the sort of higher order levels of
37:17the of the hierarchy of sensory motor
37:20framing associated with cognitive
37:23abstractions and the lowest levels
37:25associated with the sorts of things that
37:26you do with your
37:28spine and this I flip this upside down
37:32here because
37:34it's I I've been very interested in how
37:37people get traumatized and it's easier
37:39to think of trauma when you flip the
37:41thing because once you develop the
37:43higher order abstractions cortically you
37:45know you say well I'm a good person
37:47let's say then that sort of the the fact
37:50that you're a good person or what
37:52constitutes good starts to become a box
37:55the box within which all the things that
37:57are associated with it are put it's one
37:59of the dangers of abstraction right and
38:02categorization because if you couldn't
38:04think of yourself as a good or bad
38:07person let's say you didn't have that
38:08capacity for that level of abstraction
38:10which is like a binary abstraction right
38:13good is you
38:16know one and and bad is zero so it's a
38:21really it's a
38:22really simple abstraction and so if
38:26someone if you do something that a good
38:28person wouldn't do well clearly you
38:30don't fit into the one category because
38:32a good person wouldn't do that so maybe
38:34you fit into the zero category and
38:36that's that capacity for abstraction is
38:38also precisely the sort of thing that
38:39allows human beings to undermine
38:41themselves with thought because once you
38:44have that capacity for abstraction you
38:45can make these ridiculous
38:47overgeneralizations in fact they're
38:49really simple I'm not a good person I'm
38:50a horrible person it's like that's what
38:52how someone who's really depressed
38:54thingss whenever whenever anything goes
38:56wrong and so it's the danger the
38:58powerful danger of abstraction is that
39:00you can make a terrible mistake in
39:03overgeneralization this is partly
39:05because well let's say uh I don't know
39:09you're out with your girlfriend and you
39:12flirt with someone
39:14else
39:17um so what does that say about your
39:20character well she might think that puts
39:22you in the zero category like now right
39:24you're not a good person it's like well
39:27it's complicated is that is that true do
39:29you do you belong in that zero category
39:31she might treat you like that for a week
39:33or two I mean should you be taking
39:35yourself apart completely because you've
39:37made that error or should you seek
39:39farther down the the chain of
39:41abstractions for a more specific mistake
39:44and or should she help you do that it's
39:45like well you're not a complete zero
39:47you're more like a you know 0.1 she
39:50could help you figure out exactly where
39:51in your personality hierarchy you have
39:53this fault assuming that it's a fault
39:56you know maybe it's an indic that the
39:57relationship is over who who knows
40:00so anyways I wanted to show you that
40:03because then you can develop a sense of
40:05how this hierarchical system can also
40:07lead to cataclysmic overgeneralization
40:10and that's associated with lots of
40:11different mental illnesses especially
40:13depression because depressed people
40:16generally go from a small mistake well a
40:18mistake hard to parameterize right to
40:22the highest level of abstraction say
40:24well I've made error a therefore I'm
40:25useless you know or therefore I'm bad
40:28it's not good it's uh too
40:32undifferentiated I put that in there to
40:34remind you that all these little
40:36things
40:38are um
40:41informed by the underlying hypothalamic
40:44circuits so you know that whole
40:47hierarchy has to be imagine how it's
40:49conditioned that whole hierarchy of
40:51motor output part of it is conditioned
40:53by and this is sort of like an output or
40:55an input system that swan didn't talk
40:57about sort of
40:59sensory that whole motor sensory sensory
41:02motor hierarchy sensory motor perception
41:05action hierarchy will'll say has to be
41:08constructed so that your basic
41:09motivational States stay satiated right
41:13because otherwise you get thirsty enough
41:15and you die or you get hungry enough and
41:16you die it's like you have to organize
41:19your behavior so that those basic
41:21motivations stay
41:23fulfilled so each of the little
41:28ovals that make up that hierarchy have
41:30to be organized and laid out with that
41:33set of limitations in mind but then of
41:35course there's a higher order limitation
41:38which is more the one that PJ talked
41:40about which is that not only do you have
41:42to organize your internal hierarchies to
41:45take care of all of your basic
41:46motivations but you have to do that well
41:48everyone else is doing the same thing
41:51and so in some sense the hypothalamic
41:53system that's generating the impetus for
41:56these layers layers and layers of motor
41:58output also has to do so in a social
42:01context because otherwise you know you
42:03fight to the death over a stick of bread
42:06which seems like a very
42:06counterproductive thing to do
42:11so I'm trying to point out to you how
42:14many parameters those that hierarchical
42:16organization has to meet
42:19simultaneously also that one of the
42:22implications of that is that it's not an
42:24arbitrary system like this is one of the
42:27problems I have with the radical moral
42:29relativist stance it's like wait a
42:31minute wait a minute for you to set up
42:35your perceptual and behavioral system it
42:38has to solve a whole bunch of problems
42:40like and they're really complex problems
42:42and they're and they're kind of
42:42arbitrary in some sense like you get
42:45hungry and you need to eat it's
42:47arbitrary so what that means is you
42:49can't fill that hierarchy with just any
42:50old thing you know not only does it have
42:53to work to keep all the complex parts of
42:56you functioning
42:58here and now but it has to keep them
43:00functioning here and now in a way that
43:01doesn't disturb them functioning
43:03tomorrow or the next day or the next
43:05week or the next month so that's
43:07integration across time spans that's a
43:09killer right because you can't just go
43:11out tonight and drink 40 ounces of vodka
43:13and then you know write the test on
43:14Thursday so there's a probably not so
43:18some of you might try so but then you
43:21also have
43:22to organize your behavior in the Here
43:25and Now with your behavior spread across
43:27time frames in the presence of other
43:29people who are also organizing their
43:31behavior across time frames it's like
43:33once you put that many parameters on the
43:35organization of a personality you can
43:37see right away that it can hardly be
43:39arbitrary you know it's tightly
43:42constrained okay so here's some basic
43:44emotions we talked about basic
43:46motivations and so the what we're going
43:48to do in a simple way is we're going to
43:50divide them into two positive emotions
43:52and negative emotions okay and that
43:54basically gives you extroversion and
43:56neuroticism
43:57so positive emotions they kind of fall
44:00into two classes the one class is the
44:05positive emotion you feel when you when
44:08you run a motivational frame to its
44:10limit so you're hungry you go have a
44:12peanut butter sandwich and then you're
44:14no longer hungry okay so what's the
44:17state how do you define the state after
44:20you've eaten your peanut butter sandwich
44:22and you're no longer hungry well you
44:25know you're not jumping up and down and
44:27cheering like someone who just made a
44:28touchdown right so it's it's not that
44:30kind of enthusiastic positive emotion
44:32that you see when people are celebrating
44:34you know it's more
44:36like satisfaction and and that's
44:38actually technically what it's known as
44:40satiation and so when a motivational
44:44routine runs successfully what happens
44:47is it eliminates it's it eliminates the
44:50necessity for it to exist temporarily so
44:53basically what happens is you run a a
44:54framework to its logical conclusion poof
44:57it disappears because it's done and you
44:59know you might be satisfied about that
45:01but that's the next thing that happens
45:03is another motivational framework pops
45:05up and you're you know you're in the
45:07same game it's Copus fundamentally so
45:11anyways it's satiation
45:14that is TE the term satiation is
45:17technically used to describe the state
45:20of being that's characteristic of the
45:21successful execution of a motivated
45:24frame it's also known as consumatory re
45:28word consummation consume and that's
45:31associated
45:33with
45:36unconditioned that's an unconditioned
45:39response it which means you don't have
45:41to learn it so it's a it's an
45:43unconditioned positive
45:45response so and that means that
45:49satiating stimuli when delivered to a
45:53creature in the proper motivational
45:54frame have the properties of
45:56unconditioned reward
45:57so you get three things there you know
45:59the satiation brings the mo frame
46:01motivated frame to an end the satiation
46:03is also known as consumatory reward
46:05consumatory reward is very similar to
46:07what the behaviors described as
46:10unconditioned reward unlearned so you
46:14can you can stack each of those things
46:15to know on top of each other and then
46:17you've got them the other kind of
46:19positive emotion is the positive emotion
46:22that you feel when it looks like you
46:23might get a consumatory reward
46:27right right hope curiosity anticipation
46:31excitement enthusiasm all of the
46:33positive emotions that we think of as
46:35really like happy happy usually has to
46:38do with evidence that your pursuit of a
46:41valued consumatory reward is going
46:44well okay now that that's incentive
46:47reward and the reason it's called
46:48incentive reward is because you're
46:50incentivized to move forward to the
46:52reward and the moving forward the
46:54impulse to move forward towards a desire
46:57goal that's what your positive emotion
47:00systems the dopaminergic systems that
47:02are nestled have the roots in the
47:05hypothalamus that's what they motivate
47:07you to do that's what positive emotion
47:10is fundamentally positive emotion is
47:12there's something good I'm going to go
47:13get it it's the I'm going to go get it
47:15part that's associated with excitement
47:17and positive emotion it's what you feel
47:19maybe you're an extrovert you want to go
47:20to a party and so you're probably more
47:22excited about going to the party than
47:24you will be when you get there you know
47:26because it's the it's the apprehension
47:28of the reward that's with human beings
47:30because we're such weird creatures so
47:32often the apprehension of the
47:33consumatory reward is a more powerful
47:36emotion than the emotion that's actually
47:38felt as a consequence of gaining the
47:40reward itself and that's partly and this
47:43is where it gets a little more
47:44complicated that's partly because we're
47:45so bloody exploratory you know
47:48so there's things that you can learn
47:51about that are associated with a
47:52consumatory
47:53reward those are conditioned Rewards so
47:57an incentive reward and a conditioned
47:58reward are in the same category
48:01although not all incentive rewards are
48:04learned this is where the behaviors went
48:05wrong because the behaviors thought
48:07there are consumatory rewards those are
48:09unconditioned rewards to get a
48:12conditioned to if you condition a
48:15stimulus to an unconditioned reward you
48:17get a conditioned stimulus with a
48:19conditioned reward as a response but the
48:22problem with that line of thinking is
48:23that there's actually incentive reward
48:25circuitry it's not just secondary
48:28learning it's like incentive rewards
48:30have been around so long so those are
48:31things that indicate that a consumatory
48:33reward is coming they've been around so
48:35long that your brain has developed its
48:37own circuit for that and that's the one
48:38that produces positive emotion and so
48:41that's also produced by the way if you
48:44when you're taking a drug of some sort
48:46that you really
48:47like that's because it's activating this
48:49dopaminergic incentive reward system if
48:52you take a drug that activates
48:54consumatory reward you just like lay in
48:55front of the fire like a sleeping dog
48:57you know it's it's not exciting it's
49:00cocaine amphetamines alcohol for lots of
49:02people nail the incentive reward system
49:04and that's the dopaminergic exploratory
49:06system that emerges out of the
49:08hypothalamus and it's also the thing
49:10that learns what to associate with
49:12consumatory rewards so I know that's a
49:15lot to take in but well it doesn't
49:18matter that's how it is
49:20so so the approach systems respond to
49:24cues of consumatory reward and they they
49:27also they also respond to a large set of
49:30um biologically prepared stimuli smells
49:34for example
49:36so now you should approach good things
49:39but if a bad thing happens what should
49:41you do well one thing you should do is
49:44stop another thing you should do is get
49:46the hell out of there so there's a
49:49constellation of negative emotions that
49:50are associated with defense and
49:52avoidance and we kind of ran through
49:54those already pain grief frustration
49:56disappointment and then fear which is
50:00sort of what you
50:01learn you learn that things to be feared
50:05signal primary pain stimulus you know so
50:09a child's going to be afraid of a needle
50:11especially if a child's got a needle
50:12before most children are smart enough to
50:14figure out they should be afraid of the
50:16needle even when they haven't had it but
50:18the the thing is is that if you come
50:20into contact with something that's
50:21already caused you pain and now there's
50:24something that only signals that that's
50:26likely to happen that's when you
50:28experience
50:29fear okay and fear is its own circuit
50:31again which is where the behaviorist in
50:34some sense went a little bit wrong too
50:36because they thought of unconditioned
50:37punishment which produces pain as the
50:40primary motivational system so it would
50:42be unconditioned punishment
50:44unconditioned reward then there were
50:46things you learned about those that
50:47produced conditioned punishment
50:49conditioned reward okay but all of those
50:51have circuits independent circuits so
50:54the defense and avoidance negative
50:56emotion seem to be roughly pain anxiety
50:59and fear but then there's disgust and
51:01people have been looking at disgust a
51:03lot lately and it doesn't load on
51:04neuroticism it doesn't seem to load on
51:06neuroticism so it's its own circuit so
51:10okay so here's another one other
51:12complexity that you need to Grapple with
51:14which is there are things that hurt that
51:17cause you pain there are things that are
51:20satiating and that are consumatory
51:22reward then there are things that signal
51:25each of those but there's one class of
51:28stimuli so to speak or things that
51:29you're going to encounter that are
51:31paradoxical and that's the class of
51:33things that you don't understand that's
51:36novelty and Novelty it's it's it's
51:39novelty itself that's sort of associated
51:41with what the phenomenologists are
51:43primarily concerned about the idea of
51:45the revelation of meaning because the
51:47revelation of meaning is mostly
51:48associated with you encountering
51:51something that you haven't already
51:52understood right you explore that new
51:55information comes out of it A New U
51:57comes out of it okay so you're going
51:59from point A to point B what might
52:02happen
52:04well things might happen that that
52:07appear to demonstrate that you're on the
52:08right track so that makes you happy
52:11that's the yellow box positive emotion
52:13you know your your pathway is being
52:16facilitated so that's why tools are sort
52:18sort of in that category or you can be
52:20moving towards point B and you get
52:22something gets in your way and that
52:24might be something that hurts you that'
52:27be and that hurt would be pain or
52:29disappointment or frustration or grief
52:31or something that signals that you might
52:33get hurt which is threat and that
52:35produces fear and so the positive
52:38emotion is moving you towards the
52:41desired goal and the negative emotion is
52:43protecting you and so if a negative
52:47things happens you'll stop and then
52:48you'll reconfigure the behavior that
52:51you're using or the framework in order
52:52to get around the obstacle and to
52:53continue or if it's a bad enough
52:55obstacle you'll
52:57you might say well I'm
52:59not I'm too tired to eat and I'm too
53:02hungry to sleep that happens to people
53:04right it's a conflict of motivations and
53:07so if you get up and you go into the
53:09cupboard and you find out there's
53:10nothing to eat you might say oh to hell
53:12with it then I'll just go to sleep you
53:14know so sometimes the way you solve a
53:16problem is by flipping the problem it's
53:18like we're not going to solve that
53:19problem right now we'll turn to another
53:20problem some and that's an exp that's an
53:22exploratory move sometimes you operate
53:25within the frame you know you go to the
53:27cupboard the cupboard is
53:29bare but you're hungry so you walk down
53:31to the corner store and you get
53:32something to eat and so that way you've
53:34sort of stayed within the frame and
53:37altered you know you've altered your
53:39behavior to
53:41to you've thought up another path and
53:43altered your behavior so that that
53:46motivated State can run to
53:51completion there's another way of
53:52looking at it you can be moving from
53:54point A to B and what you predict or
53:57want is happening that's a good thing
54:00that keeps your mood straight and you
54:02happy and that makes you hope that's a
54:04promise with the promise is you're going
54:05to get what you want and that fills you
54:08with hope that's positive emotion or you
54:10can have an unpredicted outcome when
54:11you're you know you uh I don't know
54:14you're supposed to be going out with
54:15your friend you go to the door you knock
54:19and there's nobody there so it's like
54:21what's up with that and so it's in a
54:23sense when that happens there's like a
54:24hole in your framework you know because
54:26your framework was predicated on the
54:28presence of your friend right it was a
54:31presupposition and so now and then
54:33you'll run out of Behavioral routine and
54:34one of your presuppositions is wrong
54:36it's sort of like there's a hole in your
54:38theory and the hole you sort of drop
54:41into it and when you drop into that hole
54:43you get anxious because you don't know
54:45exactly what this unexpected thing means
54:49and behind that you get exploratory so
54:52with most
54:54people they're going to get afraid first
54:56going to have negative emotion first
54:57when their little plan is blown and then
55:00if nothing additionally awful happens
55:01and if they don't drive themselves crazy
55:04with some hypothesis about he doesn't
55:06like me anymore and so no one likes me
55:07anymore so I'm a terrible person you
55:10know then the what's they calm down a
55:13little bit the exploration circuit will
55:14come up and maybe they'll walk somewhere
55:17else go to a bar or maybe they'll stand
55:19there and think well you know this
55:20didn't work out so what else could I do
55:22an emotionally stable person say a
55:24non-neurotic person they'll flip to that
55:26really fast especially if they're
55:27extroverted and open whereas someone
55:29who's heavy a negative emotion you know
55:31the fact that their friend wasn't there
55:33when they told him they would be that
55:35might just produce a hole that they fall
55:36into and it's you know so deep and
55:38painful they just go home and cry so so
55:41the
55:42neuroticism and the extroversion are in
55:44some sense they vary with the degree to
55:47which the negative emotion system is
55:50strong or the positive emotion system is
55:52strong and they're two different systems
55:54and so you can think of them in some
55:55sense you think of them
55:59as units of positive emotion per unit of
56:03promise I mean it's a weird thing to try
56:06to quantify or units of negative emotion
56:09per unit of threat so you know if
56:12someone maybe someone there's a rumor
56:14going around that you're going to lose
56:16your job well how much should you worry
56:18about that well God you don't know so
56:21how do you decide well you don't you're
56:23your wiring decides so if you're high
56:25negative emotion you're going to get all
56:26anxious and freak out about it which
56:28might be the right thing to do maybe you
56:29will lose your job and if you're
56:31emotionally stable you're going to think
56:33ah I probably won't lose my job but even
56:36if I can even if I do I'm I'm not going
56:38to worry about it it's innate or a lot
56:40of it's innate
56:44so okay so to recapitulate learning
56:48theory behaviorism there are
56:50unconditioned
56:52rewards those are rewards you don't have
56:54to learn those are the things that bring
56:56a motivated state to its closure roughly
57:00speaking and that makes you satisfied
57:02satiation that by the way is associated
57:04with serotonin serotonin is a satiating
57:08neurochemical so if your levels of
57:10Serotonin are high you're kind of
57:12satisfied which means you don't
57:13experience a lot of positive emotion or
57:15a lot of negative emotion you're just
57:17kind of satisfied it's a high dominance
57:19thing it's like all the consumatory
57:21rewards are there when you need them you
57:23don't have to worry and you don't have
57:25to get too excited
57:27conditioned Rewards or incentive rewards
57:30indicate progress towards a consum
57:32consumatory reward they can be learned
57:34or conditioned but they can also be
57:36innate and they're associated with
57:37dopaminergic activation and that's the
57:39exploration circuit that comes out of
57:41the hypothalamus half the hyp
57:43hypothalamus does goal
57:46specification and the other half does
57:48exploration and so again if you're
57:51pursuing something that's an
57:52identifiable goal and you fail
57:56well then you're going to back off
57:58that's negative emotion then you're
57:59going to start to explore and that's
58:01that dopam energic
58:03circuit what's associated with
58:05dopaminergic
58:08activation exploration extroversion
58:11happiness play enthusiasm assertiveness
58:14and the positive element of novelty okay
58:16soes that make sense anybody have any
58:19questions I know that's a lot of
58:20information but I I kind of designed
58:22this part of the course so that at this
58:24point the levels of analysis would stack
58:26up so that you could understand them
58:29simultaneously so the
58:32hypothalamus sets up your frames of
58:37motivation running one of those to the
58:39to its positive conclusion that's
58:42satisfying that's innate it's cons it's
58:45consumatory reward you'll work for that
58:47anything that indicates that that might
58:49happen that's incentive reward you can
58:52learn that but some of it's also
58:54innate which is where the the behavior
58:56didn't know that cuz they thought of all
58:57all the the secondary stuff the
58:59condition stuff has learned it's not all
59:01learned some of it's already prepared
59:02you see a snake that's a threat you
59:04don't have to learn that so fire is sort
59:08of like that as well um blood is like
59:10that teeth are like that staring eyes
59:13are like that predatory postures are
59:15like that
59:17um loud loud vocalizations especially if
59:21they're like low low in uh frequency
59:25they indicate a large animal all those
59:27things are things you don't have to
59:28learn to be afraid of because they've
59:30been so consistently dangerous in the
59:32past that you've built up a circuit that
59:34responds automatically to them question
59:37um the extroversion and neuroticism like
59:41it seems like they're well at least in
59:43the example that you gave that um
59:45they're kind of mutually exclusive or
59:47that as or do you know what I mean yeah
59:49it's complicated you know because they
59:51do play a bit of an inhibitory role but
59:53they're separate circuits you know so
59:56you can be very extroverted and very
59:58high in negative emotion
1:00:00so and you can be very emotionally
1:00:04stable and very low in extroversion too
1:00:06so but they are definitely separate
1:00:08things now it's hard you know you can
1:00:10flip from laughing to crying very
1:00:12rapidly you know so people are very much
1:00:14capable of experiencing mixed states of
1:00:17positive and negative emotion plus there
1:00:19are forms of manic depressive disorder
1:00:21where people are Manic and depressed at
1:00:22the same time which I wouldn't recommend
1:00:25the people know that have had that they
1:00:27they seem to think that is certainly not
1:00:28fun
1:00:32so agitation okay tremendous agitation
1:00:36So you you're probably sort of like that
1:00:38when you're deeply confused and you're
1:00:39really bothered by it because then the
1:00:41threat circuits are going but you're
1:00:43also sort of wandering around going oh
1:00:45what am I going to do that's all that's
1:00:47all like approach Behavior approach
1:00:50motivation isn't always positive E I
1:00:52mean most of the time it is but
1:00:54intensity matters and control ability
1:00:56matters too so okay unconditioned
1:01:02punishments fundamentally they produce
1:01:04pain they also tend
1:01:07to if you run a behavioral routine or a
1:01:11motivated framework that results in
1:01:14punishment you're less likely to run it
1:01:15again in the future that's learning if
1:01:19you run a motivated frame and it works
1:01:21you're more likely to run it in the
1:01:22future that's learning
1:01:24too so
1:01:27unconditioned punishments decrease the
1:01:28probability that you're going to run a
1:01:30given motivational frame because it it
1:01:32it failed right you you ran it and you
1:01:33you got hurt it's like don't do that
1:01:35again that's part of the purpose of
1:01:37memory and the pain-like emotions just
1:01:40to say it again are pain frustration
1:01:43disappointment grief sadness is in there
1:01:46as well so those are pain-like states of
1:01:49emotion condition
1:01:51punishments those are things that
1:01:53indicate that a punishment is likely
1:01:56some of them you can learn some of them
1:01:57you don't have to because they're
1:01:59already built into you the negative
1:02:02emotions are dampened by
1:02:04serotonin that's the fundamental brain
1:02:06system fundamentally the serotonergic
1:02:08system is like a conductor of the
1:02:09orchestra it keeps everything in in
1:02:12balance and Gaba Gaba is a anxiolytic it
1:02:17makes people less anxious it's
1:02:18endogenous your brain produces it if you
1:02:21take valium or barbituates they act on
1:02:24the Gaba system and does alcohol that's
1:02:27part of the reason why people like
1:02:28alcohol because it dampens anxiety now
1:02:30for some people alcohol also produces
1:02:33dopaminergic Activation so they really
1:02:35like alcohol because it calms them down
1:02:38like they're not anxious anymore and it
1:02:41it also feels it produces incentive
1:02:43reward activation Like Cocaine so for
1:02:45some people alcohol is an absolutely
1:02:47deadly drug you can probably find out if
1:02:50you're susceptible to alcoholism quite
1:02:53straightforwardly if you want to find
1:02:55out
1:02:56sit in a bar take your
1:02:59pulse down five
1:03:02shots four shots if you're little you
1:03:05got to get your you got to get your
1:03:06blood alcohol level above legal
1:03:08intoxication or you won't be able to
1:03:10tell and then take your pulse again 10
1:03:12minutes later if your pulse has gone up
1:03:14eight beats or more watch it because
1:03:17you're probably producing an opiate
1:03:19response to alcohol secondary
1:03:21consequence of the opiate response is a
1:03:23dopaminergic response reasonable
1:03:25probability that you'll like alcohol
1:03:26enough to find it difficult to stop
1:03:29drinking once you start some of you are
1:03:31probably like that right you have a few
1:03:32drinks it's
1:03:34likew that's how we do it in Alberta
1:03:36anyways
1:03:37so so part of that's queuing the
1:03:40incentive reward system and because it's
1:03:42an approach system and it's being queed
1:03:44by the alcohol you just continue to hit
1:03:47it and the dopamine kicks only occur as
1:03:51your blood alcohol level is rising so
1:03:54you have to keep nailing it nailing
1:03:56yourself with alcohol because otherwise
1:03:57your blood alcohol level won't keep
1:03:59rising and you won't get that nice
1:04:01enthusiasm and assertiveness that goes
1:04:03along with the Positive element of
1:04:07alcohol neuroticism so this is the
1:04:09neuroticism dimension um there's a
1:04:13gender difference in neuroticism women
1:04:15are about half a standard deviation
1:04:18higher negative emotion than men It's
1:04:21seems like a crosscultural universal the
1:04:23difference is more enhanced and egal
1:04:26States like Scandinavia which is exactly
1:04:28the opposite of what you'd presume right
1:04:30if you were say u a
1:04:34radical I can't remember the name if
1:04:37you're someone who believes that
1:04:38everything occurs as a consequence of
1:04:40socialization as you equalize a society
1:04:43the gender differences in personality
1:04:45become larger rather than smaller so
1:04:47which is you know not what anybody
1:04:49expected but that's what happened so
1:04:51boys and girls seem to have about the
1:04:53same level of negative emotion but it's
1:04:55as puberty hits women become higher
1:04:57negative emotion than men on average
1:04:59there's still a lot of overlap between
1:05:01the genders and it never goes away again
1:05:04Across the Life Course once it kicks it
1:05:06in puberty and the reasons for that
1:05:08women are smaller their their upper
1:05:10bodies are weaker so they're more
1:05:12physical they're they're at a physical
1:05:14disadvantage if they're in a dominance
1:05:16dispute they're sexually vulnerable plus
1:05:18they have to take care of infants so I
1:05:20think those four things are probably
1:05:22enough to tilt the nervous system of
1:05:24women more towards negative negative
1:05:27emotion I've often thought maybe that
1:05:29women's NE emotional systems the
1:05:31negative ones in particular are actually
1:05:33not tuned to the woman I think they're
1:05:36tuned to the woman infant
1:05:38combination so you know be if you think
1:05:41about it from an if you think about it
1:05:43for a bit it almost has to be that way
1:05:45because an infant has to be carried
1:05:46around for like a year and a half and so
1:05:49at that point when you have an infant
1:05:51and maybe you're going to have 10 you
1:05:53know you guys won't but in the
1:05:54evolutionary past that would have been
1:05:56the case you'd have an infant for a much
1:05:58of your life and then you'd be a
1:05:59grandmother and have an infant it's like
1:06:02why wouldn't your nervous system be
1:06:04tuned at puberty for the two of you
1:06:06instead of one of you so how how could
1:06:09it be any other way
1:06:11anyways so you've got your hypothalamus
1:06:14and then on top of that you've got some
1:06:16circuits that deal with memory and
1:06:17emotion so I'm going to run you through
1:06:19the hippocampus of the amigdala
1:06:20relatively quickly so this is a theory
1:06:22that was basically put together by soov
1:06:25who Russian neuros psychologist back in
1:06:261962 but it's a variant of a theory that
1:06:29Norbert Winer developed back in the' 40s
1:06:31so here's the
1:06:32idea you wander through the world and
1:06:35you if you're in a place that you
1:06:39know your memory
1:06:42systems the hippocampus looks inside
1:06:45your memory systems to see what it is
1:06:48that you want to have happen based on
1:06:51your understanding of the world Okay so
1:06:55you're in a motivated state but you have
1:06:57certain expectations that make sense
1:06:59within that state so the hippocampus is
1:07:01watching what you think is going to
1:07:03happen but remember that's motivated
1:07:05it's not just expectation and then the
1:07:07hippocampus is also looking at the
1:07:11world now it it's looking at an
1:07:14interpretation of the world because you
1:07:16can't help but interpret the world but
1:07:18fundamentally the hippocampus is looking
1:07:20inside you and outside you and then it's
1:07:23seeing if what's happening inside and
1:07:26what's happening outside are the same
1:07:28which means you know what you're doing
1:07:31and you know where you are and if
1:07:32they're the same so if it detects a
1:07:34match then the hippocampus inhibits the
1:07:37amydala
1:07:38and the hypothalamus roughly speaking
1:07:41now what it actually seems to do there's
1:07:43a little circuit in your brain stem
1:07:45called the reticular activating circuit
1:07:47and it's the thing that turns your brain
1:07:48on at night if you're sleeping and you
1:07:50hear a noise that you shouldn't hear
1:07:51it's like bang you're awake it's the
1:07:53reticular activating system way down in
1:07:55your brain stem puts your cortex into a
1:07:59high arousal State and poof you're
1:08:00conscious now the hippocampus tells the
1:08:04reticular activating system to basically
1:08:06remain calm as well as as long as what
1:08:10it what you're expecting and Desiring
1:08:13and what's happening are the same thing
1:08:14so it's sort of like it's saying I know
1:08:17you could jump up and freak out and run
1:08:18about but you don't have to right now
1:08:20because everything's going according to
1:08:21plan but as soon as there's a deviation
1:08:24that's anomaly say okay then the
1:08:26hippocampus says Whoa something's wrong
1:08:29here and the IT disinhibits the
1:08:31reticular activating system that turns
1:08:33on your emotions especially your
1:08:35negative emotion but it primes your
1:08:36positive emotion and it primes some of
1:08:38the hypothalamic circuits too or
1:08:40disinhibits them because one way of
1:08:42solving the fact that something isn't
1:08:44going well is to switch to something
1:08:46else so it's sort of like there's a
1:08:49bunch of circuits on underneath you but
1:08:51they're being held back like horses in a
1:08:54racehorse and and then something that
1:08:56you don't expect happens and the gates
1:08:58come up a little bit because then you're
1:09:00prepared now a lot of that's negative
1:09:01emotion oh oh you don't know where you
1:09:03are but a lot a lot of the rest of it is
1:09:05be prepared to do whatever the hell you
1:09:07might need to do next and so anomaly the
1:09:11hippocampus detects anomaly that's
1:09:13something unexpected and then it
1:09:15disinhibits your lower circuitry and it
1:09:17gets you ready to go now the problem
1:09:21is how worried should you be when
1:09:23something that you don't expect happens
1:09:26and the answer to that is you don't know
1:09:29that's a big problem with life because
1:09:30now something went wrong here's the
1:09:33possibilities you're not looking at the
1:09:35world right so it's actually a
1:09:36perceptual problem right like gray for
1:09:40example believes that you just see the
1:09:41world just like it is because he's sort
1:09:43of a behaviorist it's full of stimuli
1:09:45you don't have to interpret them that's
1:09:46wrong you have to interpret them so if
1:09:48something goes wrong it might be that
1:09:50you're looking at things wrong your
1:09:52perceptual systems are out it's unlikely
1:09:54but sometimes it's the case
1:09:56but forget that let's say that you're
1:09:58looking at the world correctly and you
1:10:00know your inferences about what went
1:10:02wrong what went wrong isn't a
1:10:04consequence of you misperceiving it's a
1:10:07consequence of some stupid problem with
1:10:10your stupid plan the problem is you
1:10:12don't know where the error is located
1:10:15and that's why I think there's
1:10:19temperament sometimes if something
1:10:21unexpected happens you should really
1:10:23freak out other times times you should
1:10:25ignore it but you can't tell which of
1:10:27those is true right away so what happens
1:10:29is there's a distribution when a little
1:10:32thing happens some people really get
1:10:33upset about it and other people hardly
1:10:35care at all and sometimes the people who
1:10:37get really upset about it are right and
1:10:39sometimes the people who don't care at
1:10:41all are right and that's why there's
1:10:43variability in
1:10:45neuroticism okay now what you do when
1:10:47you're exploring is you start to
1:10:49decompose your plan right if you're if
1:10:51you if you can manage it if you're not
1:10:52so like gripped by anxiety that you're
1:10:55paralyzed then you go into your plan and
1:10:57you think well am I a complete like
1:10:59loser or is it some micro thing that's
1:11:01gone wrong and then you can start to
1:11:02decompose it and reconstruct your plant
1:11:05okay
1:11:06so yeah the other the other thing that
1:11:10this little diagram helps you understand
1:11:12it's like look what happens is when
1:11:14you're laying out a plan a motivated
1:11:16plan and a hole appears in it you have
1:11:19to figure out why you fell in the hole
1:11:20and then what you have to do is you have
1:11:22to take that motivated plan that's kind
1:11:24of running on automatic
1:11:25and you have to remember what it's made
1:11:27out of and so what opens up underneath
1:11:29you when when you've made a mistake is
1:11:31the complexity of the plan and then also
1:11:34potentially the complexity of the world
1:11:36on the off chance that you misperceived
1:11:38it right you're just someone might say
1:11:40you're not understanding me properly you
1:11:42know maybe there's something wrong with
1:11:43you that's interfering with the
1:11:44perception and then you have to do this
1:11:46massive search to try to figure out
1:11:48where the error lies now part of the
1:11:51reason I believe that people stick to
1:11:53their beliefs so hard is because people
1:11:55don't like it when a hole appears in one
1:11:57of their big abstractions right so
1:12:00they've got these high order
1:12:01representations of the world that are
1:12:03shorthand ways of representing something
1:12:05they're sort of like axioms of faith and
1:12:08if they if a hole appears in one of
1:12:10their axioms of Faith then all this
1:12:12complexity comes rushing up and it's
1:12:14overwhelming and so people hate it when
1:12:16you undermine one of their high order
1:12:20abstractions and so I think I told you
1:12:22this before don't do that in
1:12:23relationships right it's best not to do
1:12:25it to yourself as well I'll stop with
1:12:28this these are
1:12:30medusas and what what happens when you
1:12:32see the
1:12:34Medusa okay so what what what might that
1:12:38mean you bet it's the it's a prey
1:12:41response and so that's a sort of that's
1:12:44the sort of thing that occurs
1:12:46when you're moving towards your goal in
1:12:49your frame and the bottom drops out it's
1:12:52like uhoh what's
1:12:54there you don't know so what's the
1:12:56logical First Response well if you're
1:12:58high neuroticism it's going to be this
1:13:00you're going to freeze and then and only
1:13:03then if nothing else terrible happens to
1:13:05you you'll start to relax a bit and then
1:13:08maybe you'll start to investigate the
1:13:09structure of your plan and maybe you'll
1:13:11start to investigate the structure of
1:13:12the world and then from a constructivist
1:13:15perspective say once you start to do
1:13:16that you gather information from the
1:13:19world and then you remake your plan and
1:13:21You remake your conception of the world
1:13:22and then you could move on so you do
1:13:25that under the guidance of the positive
1:13:27and the negative emotions okay that's
1:13:29good we'll see you Tuesday
