[Applause] so everytime our heart beats it sends a

so everytime our heart beats it sends a

so everytime our heart beats it sends a signal to your brain and this is what I

signal to your brain and this is what I

signal to your brain and this is what I think is so amazing about the complexity

think is so amazing about the complexity

think is so amazing about the complexity of our brain that it’s responding to the

of our brain that it’s responding to the

of our brain that it’s responding to the outside while it’s also responding to

outside while it’s also responding to

outside while it’s also responding to your hidden thoughts and then

your hidden thoughts and then

your hidden thoughts and then simultaneously it also has represented

simultaneously it also has represented

simultaneously it also has represented in its activity the moment-to-moment

in its activity the moment-to-moment

in its activity the moment-to-moment fluctuations and signals that are coming

fluctuations and signals that are coming

fluctuations and signals that are coming from your internal visceral organs so as

from your internal visceral organs so as

from your internal visceral organs so as you sit here listening your brain is

you sit here listening your brain is

you sit here listening your brain is activating with each heartbeat and it’s

activating with each heartbeat and it’s

activating with each heartbeat and it’s not just your heart you have represented

not just your heart you have represented

not just your heart you have represented in the neural activity of your brain

in the neural activity of your brain

in the neural activity of your brain signals from the other organs as well so

signals from the other organs as well so

signals from the other organs as well so you also have for example the slow wave

you also have for example the slow wave

you also have for example the slow wave of the stomach also being represented in

of the stomach also being represented in

of the stomach also being represented in your brains right now thus our minds and

your brains right now thus our minds and

your brains right now thus our minds and our bodies are intrinsically and

our bodies are intrinsically and

our bodies are intrinsically and dynamically coupled our thoughts

dynamically coupled our thoughts

dynamically coupled our thoughts feelings and behaviors are shaped by

feelings and behaviors are shaped by

feelings and behaviors are shaped by imparts the internal signals that arise

imparts the internal signals that arise

imparts the internal signals that arise from our body and this is important

from our body and this is important

from our body and this is important because the signals from our body are

because the signals from our body are

because the signals from our body are informative our hearts do not just beat

informative our hearts do not just beat

informative our hearts do not just beat regularly and in fact our hearts have

regularly and in fact our hearts have

regularly and in fact our hearts have these beautiful patterns of activation

these beautiful patterns of activation

these beautiful patterns of activation and flutters and curves of increasing

and flutters and curves of increasing

and flutters and curves of increasing and decreasing activity and these

and decreasing activity and these

and decreasing activity and these different signatures are associated of

different signatures are associated of

different signatures are associated of different states for example if you’re

different states for example if you’re

different states for example if you’re sitting here waiting in anticipation

sitting here waiting in anticipation

sitting here waiting in anticipation then your heart does this classic

then your heart does this classic

then your heart does this classic slowing down and this will happen when

slowing down and this will happen when

slowing down and this will happen when you’re waiting at the traffic lights and

you’re waiting at the traffic lights and

you’re waiting at the traffic lights and other day-to-day activities and you also

other day-to-day activities and you also

other day-to-day activities and you also have these patterns of acceleration and

have these patterns of acceleration and

have these patterns of acceleration and the acceleration curves that occur with

the acceleration curves that occur with

the acceleration curves that occur with different emotional states and if you

different emotional states and if you

different emotional states and if you model these cardiac changes and brain

model these cardiac changes and brain

model these cardiac changes and brain and see which areas are Co activated you

and see which areas are Co activated you

and see which areas are Co activated you have areas involved in a motion that

have areas involved in a motion that

have areas involved in a motion that corrective a with changes in the heart

corrective a with changes in the heart

corrective a with changes in the heart and this helps observe this

and this helps observe this

and this helps observe this there that our feelings derived from

there that our feelings derived from

there that our feelings derived from this dynamic relationship between brain

this dynamic relationship between brain

this dynamic relationship between brain and body and our senses thus fall into

and body and our senses thus fall into

and body and our senses thus fall into different categories you have X

different categories you have X

different categories you have X reception which is sense in the outside

reception which is sense in the outside

reception which is sense in the outside world and this occurs through

world and this occurs through

world and this occurs through traditional senses such as sight and

traditional senses such as sight and

traditional senses such as sight and also touch these can be contrasted from

also touch these can be contrasted from

also touch these can be contrasted from the proprioception which is sensing the

the proprioception which is sensing the

the proprioception which is sensing the position of your body and space and this

position of your body and space and this

position of your body and space and this too then can be contrasted to

too then can be contrasted to

too then can be contrasted to interception which is sensing the inside

interception which is sensing the inside

interception which is sensing the inside world such as your internal visceral

world such as your internal visceral

world such as your internal visceral organs such as your heartbeats

organs such as your heartbeats

organs such as your heartbeats and if you were to come to my lab then I

and if you were to come to my lab then I

and if you were to come to my lab then I would sit you down and I would test how

would sit you down and I would test how

would sit you down and I would test how accurately you can detect when your

accurately you can detect when your

accurately you can detect when your heart is beating and we can do this with

heart is beating and we can do this with

heart is beating and we can do this with different tests for example I will

different tests for example I will

different tests for example I will attach the pulse oximeter your finger

attach the pulse oximeter your finger

attach the pulse oximeter your finger and I might simply get you to count the

and I might simply get you to count the

and I might simply get you to count the number of heartbeats while you’re at

number of heartbeats while you’re at

number of heartbeats while you’re at rest and see how accurate you are or I

rest and see how accurate you are or I

rest and see how accurate you are or I might play you tones and sync an outer

might play you tones and sync an outer

might play you tones and sync an outer sync with your heart and see how well

sync with your heart and see how well

sync with your heart and see how well you can make these super nasty judgments

you can make these super nasty judgments

you can make these super nasty judgments and these are classic happy detection

and these are classic happy detection

and these are classic happy detection tests but my work shows and that people

tests but my work shows and that people

tests but my work shows and that people don’t necessarily have insight into how

don’t necessarily have insight into how

don’t necessarily have insight into how good or poor they are so you might think

good or poor they are so you might think

good or poor they are so you might think you’re guessing on every trial but

you’re guessing on every trial but

you’re guessing on every trial but actually you might be performing

actually you might be performing

actually you might be performing perfectly at these tasks and thus we can

perfectly at these tasks and thus we can

perfectly at these tasks and thus we can characterize individual differences in

characterize individual differences in

characterize individual differences in interceptive accuracy and interoceptive

interceptive accuracy and interoceptive

interceptive accuracy and interoceptive awareness and then see how these

awareness and then see how these

awareness and then see how these individual differences they’re map on to

individual differences they’re map on to

individual differences they’re map on to the way in which you experience emotion

the way in which you experience emotion

the way in which you experience emotion and the role of the body in emotion has

long been known William James in 1884 theorized that it’s the sensing of

theorized that it’s the sensing of

theorized that it’s the sensing of internal bodily sensations that gives

internal bodily sensations that gives

internal bodily sensations that gives rise to emotional experience that you’re

rise to emotional experience that you’re

rise to emotional experience that you’re not afraid because you you run or you’re

not afraid because you you run or you’re

not afraid because you you run or you’re afraid it’s the act of running which

afraid it’s the act of running which

afraid it’s the act of running which gives rise to the sense of fear because

gives rise to the sense of fear because

gives rise to the sense of fear because it’s the feeling of the pounding of your

it’s the feeling of the pounding of your

it’s the feeling of the pounding of your heart which gives rise to this feeling

heart which gives rise to this feeling

heart which gives rise to this feeling of fear and we were able to look at this

of fear and we were able to look at this

of fear and we were able to look at this in the lab doing experiments to test the

in the lab doing experiments to test the

in the lab doing experiments to test the way in which the detection of

way in which the detection of

way in which the detection of sensations might increase your emotion

emotions of a greater intensity and as

emotions of a greater intensity and as modern-day Nero scientists were also

modern-day Nero scientists were also

modern-day Nero scientists were also able to look at the nearest circuitry in

able to look at the nearest circuitry in

able to look at the nearest circuitry in the brain that underlie this so if I put

the brain that underlie this so if I put

the brain that underlie this so if I put you in a scanner and get you to focus on

you in a scanner and get you to focus on

you in a scanner and get you to focus on your heart then you’ll see you activated

your heart then you’ll see you activated

your heart then you’ll see you activated this area called the anterior insula and

this area called the anterior insula and

this area called the anterior insula and the degree to which this is activated

the degree to which this is activated

the degree to which this is activated predicts how good you are at detecting

predicts how good you are at detecting

predicts how good you are at detecting your heart so the more intercepted lis

your heart so the more intercepted lis

your heart so the more intercepted lis accurate you are the more activity you

accurate you are the more activity you

accurate you are the more activity you have in this particular region and if I

have in this particular region and if I

have in this particular region and if I also get you to be emotional in the

also get you to be emotional in the

also get you to be emotional in the scanner and see which areas are

scanner and see which areas are

scanner and see which areas are underlying emotion processing in general

underlying emotion processing in general

underlying emotion processing in general you also have this area activated and in

you also have this area activated and in

you also have this area activated and in a conjunction analysis of both emotion

a conjunction analysis of both emotion

a conjunction analysis of both emotion processing and cardiac monitoring

processing and cardiac monitoring

processing and cardiac monitoring particularly shows up this area giving

particularly shows up this area giving

particularly shows up this area giving rise to the idea that this area is

rise to the idea that this area is

rise to the idea that this area is integrating bodily signals to give rise

integrating bodily signals to give rise

integrating bodily signals to give rise to the experience of emotion thus our

to the experience of emotion thus our

to the experience of emotion thus our hearts are able to guide our emotional

hearts are able to guide our emotional

hearts are able to guide our emotional experiences detecting these signals can

experiences detecting these signals can

experiences detecting these signals can influence the intensity with which we

influence the intensity with which we

influence the intensity with which we experience emotions but what I really

experience emotions but what I really

experience emotions but what I really want to speak to you about today is the

want to speak to you about today is the

want to speak to you about today is the fact that our hearts tell us not just

fact that our hearts tell us not just

fact that our hearts tell us not just about how we’re feeling but our hearts

about how we’re feeling but our hearts

about how we’re feeling but our hearts can also be informative about how other

can also be informative about how other

can also be informative about how other people around us are also feeling so for

people around us are also feeling so for

people around us are also feeling so for example in this particular experiment by

example in this particular experiment by

example in this particular experiment by conv Ling cartel they monitored the

conv Ling cartel they monitored the

conv Ling cartel they monitored the hearts of people who are undergoing

hearts of people who are undergoing

hearts of people who are undergoing particular rituals in this case a

particular rituals in this case a

particular rituals in this case a firewalking ritual where people need to

firewalking ritual where people need to

firewalking ritual where people need to walk over burning embers and coals and

walk over burning embers and coals and

walk over burning embers and coals and they monitored the heart of the person

they monitored the heart of the person

they monitored the heart of the person undergoing this and then they also

undergoing this and then they also

undergoing this and then they also monitored the hearts of all taneous lis

monitored the hearts of all taneous lis

monitored the hearts of all taneous lis to a relative or a spouse or unrelated

to a relative or a spouse or unrelated

to a relative or a spouse or unrelated observer and what they were able to see

observer and what they were able to see

observer and what they were able to see that for the related person or the

that for the related person or the

that for the related person or the person marry to the individual in

person marry to the individual in

person marry to the individual in question undergoing this you have these

question undergoing this you have these

question undergoing this you have these beautiful trappings of heart rate that

beautiful trappings of heart rate that

beautiful trappings of heart rate that happen between the individual and the

happen between the individual and the

happen between the individual and the related observer thus the cardiac

related observer thus the cardiac

related observer thus the cardiac changes that were occurring

changes that were occurring

changes that were occurring in the person going over the burning

in the person going over the burning

in the person going over the burning embers and coals were also expressed in

embers and coals were also expressed in

embers and coals were also expressed in the observer and it’s not just our

the observer and it’s not just our

the observer and it’s not just our hearts that can represent the states of

hearts that can represent the states of

hearts that can represent the states of other it can also happen in other

other it can also happen in other

other it can also happen in other physiological signatures such as the

physiological signatures such as the

physiological signatures such as the eyes and one of my favorite experiments

eyes and one of my favorite experiments

eyes and one of my favorite experiments by Neil Harrison and he really was they

by Neil Harrison and he really was they

by Neil Harrison and he really was they monitored the eyes of people and they

monitored the eyes of people and they

monitored the eyes of people and they also got people to look at faces and

also got people to look at faces and

also got people to look at faces and these faces depicted all their

these faces depicted all their

these faces depicted all their formations happy and sad and then they

formations happy and sad and then they

formations happy and sad and then they manipulated the pupil size of the faces

manipulated the pupil size of the faces

manipulated the pupil size of the faces and they found that small pupil size was

and they found that small pupil size was

and they found that small pupil size was particularly associated with sad faces

particularly associated with sad faces

particularly associated with sad faces and if a sad face had a smaller pupil

and if a sad face had a smaller pupil

and if a sad face had a smaller pupil size then people judged those faces of

size then people judged those faces of

size then people judged those faces of sadder but then what I think is so

sadder but then what I think is so

sadder but then what I think is so beautiful is that when they were

beautiful is that when they were

beautiful is that when they were monitoring the pupil size of the

monitoring the pupil size of the

monitoring the pupil size of the observer their own pupil size got

observer their own pupil size got

observer their own pupil size got smaller as well and this happens

smaller as well and this happens

smaller as well and this happens specifically sad faces thus this

specifically sad faces thus this

specifically sad faces thus this physiological signature is sadness which

physiological signature is sadness which

physiological signature is sadness which is a smaller pupil size then happens in

is a smaller pupil size then happens in

is a smaller pupil size then happens in the observer such that they’re not just

the observer such that they’re not just

the observer such that they’re not just saying or feeling sad for the person

saying or feeling sad for the person

saying or feeling sad for the person that seemed to embody and feel that

that seemed to embody and feel that

that seemed to embody and feel that feeling themselves their body is

feeling themselves their body is

feeling themselves their body is adopting the physiological signature of

adopting the physiological signature of

adopting the physiological signature of sadness such that they experience it too

sadness such that they experience it too

sadness such that they experience it too and in our search to understand these

and in our search to understand these

and in our search to understand these mechanisms are underlie emotion we can

mechanisms are underlie emotion we can

mechanisms are underlie emotion we can see how maybe populations and

see how maybe populations and

see how maybe populations and individuals who process emotions

individuals who process emotions

individuals who process emotions slightly differently may have different

slightly differently may have different

slightly differently may have different channels of information and a lot of my

channels of information and a lot of my

channels of information and a lot of my work at present is working with people

work at present is working with people

work at present is working with people with autistic spectrum conditions and

with autistic spectrum conditions and

with autistic spectrum conditions and people with autism and can have trouble

people with autism and can have trouble

people with autism and can have trouble sometimes understanding their own

sometimes understanding their own

sometimes understanding their own emotion and the emotions of others and

emotion and the emotions of others and

emotion and the emotions of others and my work where these individuals show

my work where these individuals show

my work where these individuals show that they’re also impaired in their

that they’re also impaired in their

that they’re also impaired in their capacity to really detect internal

capacity to really detect internal

capacity to really detect internal bodily signals such as their heartbeats

bodily signals such as their heartbeats

bodily signals such as their heartbeats we’re focusing on this gives you part

we’re focusing on this gives you part

we’re focusing on this gives you part the story which has potentially this is

the story which has potentially this is

the story which has potentially this is the mechanism through which a motion

the mechanism through which a motion

the mechanism through which a motion processing is potentially impaired in

processing is potentially impaired in

processing is potentially impaired in these individuals but it’s only part of

these individuals but it’s only part of

these individuals but it’s only part of the story and actually if you monitor

the story and actually if you monitor

the story and actually if you monitor their body and monitor their body while

their body and monitor their body while

their body and monitor their body while other people are experience emotions or

other people are experience emotions or

other people are experience emotions or pain then people with autism have a body

pain then people with autism have a body

pain then people with autism have a body response which shares the emotions with

response which shares the emotions with

response which shares the emotions with others so for example buit all didn’t

others so for example buit all didn’t

others so for example buit all didn’t experiments where people um had pain

experiments where people um had pain

experiments where people um had pain stimuli applied to them and people watch

stimuli applied to them and people watch

stimuli applied to them and people watch this occur and people with autism had an

this occur and people with autism had an

this occur and people with autism had an embodied skin conductance response that

embodied skin conductance response that

embodied skin conductance response that the represented pain of the other person

the represented pain of the other person

the represented pain of the other person in them so that they were having an

in them so that they were having an

in them so that they were having an embodied empathetic response but not

embodied empathetic response but not

embodied empathetic response but not being able to detect these signals

being able to detect these signals

being able to detect these signals accurately also comes with a cost so

accurately also comes with a cost so

accurately also comes with a cost so some of our work is also looking at

some of our work is also looking at

some of our work is also looking at anxiety and showing their errors and

anxiety and showing their errors and

anxiety and showing their errors and interceptive processing predicts higher

interceptive processing predicts higher

interceptive processing predicts higher anxiety symptomatology but we’re working

anxiety symptomatology but we’re working

anxiety symptomatology but we’re working now to create software platforms to make

now to create software platforms to make

now to create software platforms to make people more introspectively accurate

people more introspectively accurate

people more introspectively accurate such as heart rate and heart rate a

such as heart rate and heart rate a

such as heart rate and heart rate a clinical and we’re giving people tours

clinical and we’re giving people tours

clinical and we’re giving people tours to be more precise in detecting their

to be more precise in detecting their

to be more precise in detecting their internal bodily signals and showing that

internal bodily signals and showing that

internal bodily signals and showing that this can increase the accuracy and also

this can increase the accuracy and also

this can increase the accuracy and also potentially decrease their anxiety so

potentially decrease their anxiety so

potentially decrease their anxiety so your heart is a wonderful thing if you

your heart is a wonderful thing if you

your heart is a wonderful thing if you perceive it accurately it can help you

perceive it accurately it can help you

perceive it accurately it can help you have lower anxiety levels providing you

have lower anxiety levels providing you

have lower anxiety levels providing you just notice it’s your heart and this

just notice it’s your heart and this

just notice it’s your heart and this precision of detecting internal bodily

precision of detecting internal bodily

precision of detecting internal bodily signals can also help you experience

signals can also help you experience

signals can also help you experience motions more intensely but the thing

motions more intensely but the thing

motions more intensely but the thing that I really want to stress today is

that I really want to stress today is

that I really want to stress today is that your heart can inform you not only

that your heart can inform you not only

that your heart can inform you not only about your own emotions but also about

about your own emotions but also about

about your own emotions but also about the emotions of those people around you

the emotions of those people around you

the emotions of those people around you that our hearts and our bodies can

that our hearts and our bodies can

that our hearts and our bodies can represent other people’s joy

represent other people’s joy

represent other people’s joy less than fear within ourselves so in

less than fear within ourselves so in

less than fear within ourselves so in the search for utopia and in trying to

the search for utopia and in trying to

the search for utopia and in trying to understand how we build communities I

understand how we build communities I

understand how we build communities I believe that we build communities by

believe that we build communities by

believe that we build communities by building bonds between people and one of

building bonds between people and one of

building bonds between people and one of the ways this can happen is through our

the ways this can happen is through our

the ways this can happen is through our physiological signals representing the

physiological signals representing the

physiological signals representing the emotions of others so pay attention to

emotions of others so pay attention to

emotions of others so pay attention to your heart it will help tell you how

your heart it will help tell you how

your heart it will help tell you how you’re feeling will help you experience

you’re feeling will help you experience

you’re feeling will help you experience at other people as well thank you

at other people as well thank you

at other people as well thank you [Applause]
