[Applause]

[Applause] I’m a neuroscientist and like many

I’m a neuroscientist and like many

I’m a neuroscientist and like many neuroscientists I’m fascinated by memory

neuroscientists I’m fascinated by memory

neuroscientists I’m fascinated by memory this is Nobel Prize winner Eric Kandel

this is Nobel Prize winner Eric Kandel

this is Nobel Prize winner Eric Kandel who is one of the first people to study

who is one of the first people to study

who is one of the first people to study how the brain for his memories and he

how the brain for his memories and he

how the brain for his memories and he liked to think about memory as a kind of

liked to think about memory as a kind of

liked to think about memory as a kind of glue saying the memories the glue that

glue saying the memories the glue that

glue saying the memories the glue that holds our mental life together and that

holds our mental life together and that

holds our mental life together and that without the unifying force of memory our

without the unifying force of memory our

without the unifying force of memory our consciousness would be broken into as

consciousness would be broken into as

consciousness would be broken into as many fragments as there are seconds in

many fragments as there are seconds in

many fragments as there are seconds in the day but despite all of this interest

the day but despite all of this interest

the day but despite all of this interest in memory and the central importance of

in memory and the central importance of

in memory and the central importance of memory for our lives there’s still a lot

memory for our lives there’s still a lot

memory for our lives there’s still a lot of basic things that we don’t really

of basic things that we don’t really

of basic things that we don’t really understand about how memory works in our

understand about how memory works in our

understand about how memory works in our everyday lives so for example if

everyday lives so for example if

everyday lives so for example if memories kind of kind of like a glue how

memories kind of kind of like a glue how

memories kind of kind of like a glue how does that glue work so one possibility

does that glue work so one possibility

does that glue work so one possibility is that our memories work kind of like a

is that our memories work kind of like a

is that our memories work kind of like a video camera where every instant of our

video camera where every instant of our

video camera where every instant of our lives is joined together into a long

lives is joined together into a long

lives is joined together into a long continuous film strip another

continuous film strip another

continuous film strip another possibility is that our brain actually

possibility is that our brain actually

possibility is that our brain actually tries to divide up our day into separate

tries to divide up our day into separate

tries to divide up our day into separate chunks that correspond to different

chunks that correspond to different

chunks that correspond to different events that happen to us during the day

events that happen to us during the day

events that happen to us during the day and it basically individually wraps

and it basically individually wraps

and it basically individually wraps these little packages and that these

these little packages and that these

these little packages and that these individual event chunks are what we

individual event chunks are what we

individual event chunks are what we store interim memories over the past few

store interim memories over the past few

store interim memories over the past few years I’ve been very interested this

years I’ve been very interested this

years I’ve been very interested this question and I’ve started using

question and I’ve started using

question and I’ve started using functional MRI to measure people’s brain

functional MRI to measure people’s brain

functional MRI to measure people’s brain activity while I have them watch movies

activity while I have them watch movies

activity while I have them watch movies and listen to stories I’m going to show

and listen to stories I’m going to show

and listen to stories I’m going to show a quick example here this is average

a quick example here this is average

a quick example here this is average brain activity in response to the

brain activity in response to the

brain activity in response to the beginning of this story and some of you

beginning of this story and some of you

beginning of this story and some of you might recognize the movie this story is

might recognize the movie this story is

might recognize the movie this story is based off of and I’m focusing here on

based off of and I’m focusing here on

based off of and I’m focusing here on this particular brain region which we

this particular brain region which we

this particular brain region which we know is important for building up

know is important for building up

know is important for building up memories and what I’d like you to watch

memories and what I’d like you to watch

memories and what I’d like you to watch and see if you think that brain activity

and see if you think that brain activity

and see if you think that brain activity in this region is just constantly

in this region is just constantly

in this region is just constantly changing all the time or if it looks

changing all the time or if it looks

changing all the time or if it looks like activity in this region is

like activity in this region is

like activity in this region is switching between different patterns as

switching between different patterns as

switching between different patterns as different events happen in the story

different events happen in the story

different events happen in the story vini and mona stumbled bleary-eyed into

that although brain activity is always

that although brain activity is always kind of Epping and flowing it really

kind of Epping and flowing it really

kind of Epping and flowing it really looks like it is jumping between stable

looks like it is jumping between stable

looks like it is jumping between stable patterns of activity and that these

patterns of activity and that these

patterns of activity and that these jumps occur when there’s a new event in

jumps occur when there’s a new event in

jumps occur when there’s a new event in the story and so we think this is

the story and so we think this is

the story and so we think this is evidence that what’s happening when

evidence that what’s happening when

evidence that what’s happening when we’re trying to build memories is that

we’re trying to build memories is that

we’re trying to build memories is that we’re taking all the information that’s

we’re taking all the information that’s

we’re taking all the information that’s streaming in through our senses and

streaming in through our senses and

streaming in through our senses and trying to build up some stable model

trying to build up some stable model

trying to build up some stable model inside our heads of the current event

inside our heads of the current event

inside our heads of the current event that we’re in in the world and that

that we’re in in the world and that

that we’re in in the world and that these individual events then become our

these individual events then become our

these individual events then become our memories and so my collaborators and I

memories and so my collaborators and I

memories and so my collaborators and I have been studying a number of brain

have been studying a number of brain

have been studying a number of brain regions that we think all work together

regions that we think all work together

regions that we think all work together in order to create these events and then

in order to create these events and then

in order to create these events and then transmit them into long-term memory but

transmit them into long-term memory but

transmit them into long-term memory but we know that this can’t be the whole

we know that this can’t be the whole

we know that this can’t be the whole story because when we’re creating our

story because when we’re creating our

story because when we’re creating our memories we’re not just building them

memories we’re not just building them

memories we’re not just building them from scratch based on what’s currently

from scratch based on what’s currently

from scratch based on what’s currently happening in the world when you heard

happening in the world when you heard

happening in the world when you heard that two characters are going into a

that two characters are going into a

that two characters are going into a diner you can immediately activate all

diner you can immediately activate all

diner you can immediately activate all of this common-sense knowledge that you

of this common-sense knowledge that you

of this common-sense knowledge that you have about what typically happens in

have about what typically happens in

have about what typically happens in diners and restaurants about why they’re

diners and restaurants about why they’re

diners and restaurants about why they’re there and what what they might do next

there and what what they might do next

there and what what they might do next and so in the language of cognitive

and so in the language of cognitive

and so in the language of cognitive psychology we’d say that you’re

psychology we’d say that you’re

psychology we’d say that you’re activating a restaurant script it’s the

activating a restaurant script it’s the

activating a restaurant script it’s the idea is that you have this script about

idea is that you have this script about

idea is that you have this script about what happens at restaurants that you

what happens at restaurants that you

what happens at restaurants that you come in you’re seated with a menu you

come in you’re seated with a menu you

come in you’re seated with a menu you place your order and then finally your

place your order and then finally your

place your order and then finally your food arrives right you have other

food arrives right you have other

food arrives right you have other information too about for example what

information too about for example what

information too about for example what people’s goals are when they go to a

people’s goals are when they go to a

people’s goals are when they go to a restaurant right why might someone go

restaurant right why might someone go

restaurant right why might someone go there you might have information about

there you might have information about

there you might have information about things that can go wrong in this script

things that can go wrong in this script

things that can go wrong in this script like if you try to order something and

like if you try to order something and

like if you try to order something and the restaurant is sold out and so when

the restaurant is sold out and so when

the restaurant is sold out and so when we’re building up these models that

we’re building up these models that

we’re building up these models that become our memories we’re combining

become our memories we’re combining

become our memories we’re combining what’s currently happening in the world

what’s currently happening in the world

what’s currently happening in the world with this whole library of schematic

with this whole library of schematic

with this whole library of schematic information that we have about the way

information that we have about the way

information that we have about the way we think the world works right so you

we think the world works right so you

we think the world works right so you might have scripts

might have scripts

might have scripts not just for restaurants but for what

not just for restaurants but for what

not just for restaurants but for what happens at the doctor what happens at

happens at the doctor what happens at

happens at the doctor what happens at the airport going grocery shopping we

the airport going grocery shopping we

the airport going grocery shopping we have a lot of scripts for what happens a

have a lot of scripts for what happens a

have a lot of scripts for what happens a different type of social interactions

different type of social interactions

different type of social interactions with other people so I was interesting

with other people so I was interesting

with other people so I was interesting and trying to see how the brain stores

and trying to see how the brain stores

and trying to see how the brain stores these scripts and how it activates them

these scripts and how it activates them

these scripts and how it activates them at the right time and so what I’ve been

at the right time and so what I’ve been

at the right time and so what I’ve been doing is showing people stories that all

doing is showing people stories that all

doing is showing people stories that all have some kind of shared schematic

have some kind of shared schematic

have some kind of shared schematic script so for example in one of these

script so for example in one of these

script so for example in one of these experiments we showed people a bunch of

experiments we showed people a bunch of

experiments we showed people a bunch of different movie and and audio clips that

different movie and and audio clips that

different movie and and audio clips that were taken from scenes from restaurants

were taken from scenes from restaurants

were taken from scenes from restaurants and so all these stories are very

and so all these stories are very

and so all these stories are very different the characters are very

different the characters are very

different the characters are very different some are funny and some are

different some are funny and some are

different some are funny and some are serious they’re talking about very

serious they’re talking about very

serious they’re talking about very different things

different things

different things and I was curious to see if there’s any

and I was curious to see if there’s any

and I was curious to see if there’s any parts of the brain that can actually

parts of the brain that can actually

parts of the brain that can actually pick up on this shared restaurant script

pick up on this shared restaurant script

pick up on this shared restaurant script in these very different stories and

in these very different stories and

in these very different stories and again we find that the answer is a

again we find that the answer is a

again we find that the answer is a little complicated and there’s a lot of

little complicated and there’s a lot of

little complicated and there’s a lot of different regions involved but we have a

different regions involved but we have a

different regions involved but we have a number of reasons to think that this

number of reasons to think that this

number of reasons to think that this frontal part of the brain so this is the

frontal part of the brain so this is the

frontal part of the brain so this is the part of the brain right between the

part of the brain right between the

part of the brain right between the behind the middle of your forehead here

behind the middle of your forehead here

behind the middle of your forehead here that we think that this is really

that we think that this is really

that we think that this is really critical for bringing these scripts

critical for bringing these scripts

critical for bringing these scripts online at the right time so just to give

online at the right time so just to give

online at the right time so just to give you a sense for what life would be like

watch this and remember what happens so

watch this and remember what happens so you could so that you could tell me what

so assuming that you’re not familiar

so assuming that you’re not familiar with this videogame that was probably a

with this videogame that was probably a

with this videogame that was probably a pretty baffling experience and you

pretty baffling experience and you

pretty baffling experience and you really couldn’t form a coherent memory

really couldn’t form a coherent memory

really couldn’t form a coherent memory of what happened right you don’t really

of what happened right you don’t really

of what happened right you don’t really have a script for what typically happens

have a script for what typically happens

have a script for what typically happens to this game you don’t have an

to this game you don’t have an

to this game you don’t have an understanding of who the relevant

understanding of who the relevant

understanding of who the relevant characters are and what they’re trying

characters are and what they’re trying

characters are and what they’re trying to do you don’t even really know what

to do you don’t even really know what

to do you don’t even really know what part of the screen you’re supposed to be

part of the screen you’re supposed to be

part of the screen you’re supposed to be looking at to get information and so if

looking at to get information and so if

looking at to get information and so if these scripts are so important how do we

these scripts are so important how do we

these scripts are so important how do we actually get them into our brains and so

actually get them into our brains and so

actually get them into our brains and so one possibility is that we’re directly

one possibility is that we’re directly

one possibility is that we’re directly taught them as kids so there’s this book

taught them as kids so there’s this book

taught them as kids so there’s this book Maisie goes on a plane which I’ve read

Maisie goes on a plane which I’ve read

Maisie goes on a plane which I’ve read many many times with my children

many many times with my children

many many times with my children absolutely nothing happens in this book

absolutely nothing happens in this book

absolutely nothing happens in this book it’s basically just a straight

it’s basically just a straight

it’s basically just a straight description of the airport script right

description of the airport script right

description of the airport script right and the events that happen when you try

and the events that happen when you try

and the events that happen when you try to get on a plane so this is possible

to get on a plane so this is possible

to get on a plane so this is possible but I think by far the more common way

but I think by far the more common way

but I think by far the more common way we learn scripts is simply through

we learn scripts is simply through

we learn scripts is simply through experience right so those commenters

experience right so those commenters

experience right so those commenters that those commentators that were really

that those commentators that were really

that those commentators that were really excited at that doing a video game

excited at that doing a video game

excited at that doing a video game they’ve seen hours and hours and hours

they’ve seen hours and hours and hours

they’ve seen hours and hours and hours of this game they have a very good

of this game they have a very good

of this game they have a very good understanding of what the strategies are

understanding of what the strategies are

understanding of what the strategies are and what people are trying to do so what

and what people are trying to do so what

and what people are trying to do so what this tells us is that there’s actually a

this tells us is that there’s actually a

this tells us is that there’s actually a loop in this system that not only are we

loop in this system that not only are we

loop in this system that not only are we using these scripts to build our

using these scripts to build our

using these scripts to build our memories but over time we’re trying to

memories but over time we’re trying to

memories but over time we’re trying to look for commonalities across different

look for commonalities across different

look for commonalities across different memories to try to extract this script

memories to try to extract this script

memories to try to extract this script structure to improve our script library

structure to improve our script library

structure to improve our script library and to add new items to it another

and to add new items to it another

and to add new items to it another interesting thing to note is that this

interesting thing to note is that this

interesting thing to note is that this part of the brain that we think is

part of the brain that we think is

part of the brain that we think is critical for activating these scripts

critical for activating these scripts

critical for activating these scripts overlaps pretty strongly with the part

overlaps pretty strongly with the part

overlaps pretty strongly with the part of the brain that grows the most over

of the brain that grows the most over

of the brain that grows the most over the first 10 years of life right so what

the first 10 years of life right so what

the first 10 years of life right so what this suggests is that it takes us a very

this suggests is that it takes us a very

this suggests is that it takes us a very very long time to accumulate these

very long time to accumulate these

very long time to accumulate these scripts so here’s my older son his first

scripts so here’s my older son his first

scripts so here’s my older son his first time at a restaurant or one of his first

time at a restaurant or one of his first

time at a restaurant or one of his first times right and we first time we’re in a

times right and we first time we’re in a

times right and we first time we’re in a restaurant we have no idea what we’re

restaurant we have no idea what we’re

restaurant we have no idea what we’re supposed to be doing or what to expect

supposed to be doing or what to expect

supposed to be doing or what to expect and it takes us many many times at a

and it takes us many many times at a

and it takes us many many times at a restaurant to actually understand what

restaurant to actually understand what

restaurant to actually understand what are the sort of common pieces that

are the sort of common pieces that

are the sort of common pieces that always happened what are the things that

always happened what are the things that

always happened what are the things that sometimes happen and so as we’re

sometimes happen and so as we’re

sometimes happen and so as we’re learning more and more about the world

learning more and more about the world

learning more and more about the world we’re not just getting better

we’re not just getting better

we’re not just getting better understanding what’s happening we’re

understanding what’s happening we’re

understanding what’s happening we’re also getting better at remembering right

also getting better at remembering right

also getting better at remembering right and so being able to remember things

and so being able to remember things

and so being able to remember things well is actually not something that

well is actually not something that

well is actually not something that we’re born with we need to learn how to

we’re born with we need to learn how to

we’re born with we need to learn how to remember now I’m leaving out a lot of

remember now I’m leaving out a lot of

remember now I’m leaving out a lot of details here and there’s a lot of thing

details here and there’s a lot of thing

details here and there’s a lot of thing we don’t really understand so for

we don’t really understand so for

we don’t really understand so for example we don’t really understand

example we don’t really understand

example we don’t really understand exactly what information is in these

exactly what information is in these

exactly what information is in these scripts and what information

scripts and what information

scripts and what information specifically gets stored in our memories

specifically gets stored in our memories

specifically gets stored in our memories and there’s even a bigger question here

and there’s even a bigger question here

and there’s even a bigger question here about how do we actually represent this

about how do we actually represent this

about how do we actually represent this kind of knowledge in the hardware of the

kind of knowledge in the hardware of the

kind of knowledge in the hardware of the brain right how can we use connections

brain right how can we use connections

brain right how can we use connections between neurons to try to represent this

between neurons to try to represent this

between neurons to try to represent this information and so these questions will

information and so these questions will

information and so these questions will keep me and many other neuroscientists

keep me and many other neuroscientists

keep me and many other neuroscientists busy for a long time so I’ve been

busy for a long time so I’ve been

busy for a long time so I’ve been talking a lot about the importance of

talking a lot about the importance of

talking a lot about the importance of these scripts and why we need them but

these scripts and why we need them but

these scripts and why we need them but I’d like to just end on a more

I’d like to just end on a more

I’d like to just end on a more cautionary note about the dangers of

cautionary note about the dangers of

cautionary note about the dangers of these scripts so there’s a classic study

these scripts so there’s a classic study

these scripts so there’s a classic study in cognitive psychology from decades ago

in cognitive psychology from decades ago

in cognitive psychology from decades ago where they basically brought people in

where they basically brought people in

where they basically brought people in and asked them to try to read and

and asked them to try to read and

and asked them to try to read and remember some stories and here’s one of

remember some stories and here’s one of

remember some stories and here’s one of the stories just read the very beginning

the stories just read the very beginning

the stories just read the very beginning here that rocky got slowly got up from

here that rocky got slowly got up from

here that rocky got slowly got up from the mat planning his escape he hesitated

the mat planning his escape he hesitated

the mat planning his escape he hesitated a moment and thought things were not

a moment and thought things were not

going well well bothered and most is

going well well bothered and most is being held especially since the charge

being held especially since the charge

being held especially since the charge against him had been weak he considered

against him had been weak he considered

against him had been weak he considered his present situation the lock that held

his present situation the lock that held

his present situation the lock that held him was strong but he thought he could

him was strong but he thought he could

him was strong but he thought he could break it he knew however that his timing

break it he knew however that his timing

break it he knew however that his timing would have to be perfect so most people

would have to be perfect so most people

would have to be perfect so most people when they read the story they activate a

when they read the story they activate a

when they read the story they activate a script that this is about someone trying

script that this is about someone trying

script that this is about someone trying to break out of prison and when you ask

to break out of prison and when you ask

to break out of prison and when you ask them later what did you read they’ll say

them later what did you read they’ll say

them later what did you read they’ll say things like rocky was mad because he had

things like rocky was mad because he had

things like rocky was mad because he had been arrested but if you give this story

been arrested but if you give this story

been arrested but if you give this story to a different group of people that are

to a different group of people that are

to a different group of people that are wrestling fans they actually activate a

wrestling fans they actually activate a

wrestling fans they actually activate a different script and they’ll tell you

different script and they’ll tell you

different script and they’ll tell you this story was about someone trying to

this story was about someone trying to

this story was about someone trying to escape a headlock right and the story

escape a headlock right and the story

escape a headlock right and the story was specifically constructed so that

was specifically constructed so that

was specifically constructed so that either of these interpretations could

either of these interpretations could

either of these interpretations could make sense right and so maybe these two

make sense right and so maybe these two

make sense right and so maybe these two people had the same exact experience and

people had the same exact experience and

people had the same exact experience and walked away with totally different

walked away with totally different

walked away with totally different memories of what they had just read and

memories of what they had just read and

memories of what they had just read and so this tells us a few things first of

so this tells us a few things first of

so this tells us a few things first of all it tells us that our memories are

all it tells us that our memories are

all it tells us that our memories are not quite as infallible as we often

not quite as infallible as we often

not quite as infallible as we often think right that our memories are built

think right that our memories are built

think right that our memories are built not only from what’s happening in the

not only from what’s happening in the

not only from what’s happening in the world but also from our personal scripts

world but also from our personal scripts

world but also from our personal scripts on our beliefs about the way that the

on our beliefs about the way that the

on our beliefs about the way that the world works and it also tells us that

world works and it also tells us that

world works and it also tells us that these scripts can reinforce themselves

these scripts can reinforce themselves

these scripts can reinforce themselves over time remember there’s this loop

over time remember there’s this loop

over time remember there’s this loop where we use our scripts to build our

where we use our scripts to build our

where we use our scripts to build our memories and our memories to enforce our

memories and our memories to enforce our

memories and our memories to enforce our scripts and so when the world is vague

scripts and so when the world is vague

scripts and so when the world is vague or uncertain two different people can

or uncertain two different people can

or uncertain two different people can come with their own personal scripts and

come with their own personal scripts and

come with their own personal scripts and both walk away convinced that their

both walk away convinced that their

both walk away convinced that their beliefs about the world have been

beliefs about the world have been
