[Music]

hey

so in my experiment before you saw how

our senses sometimes work together

what we see might affect what we taste

we're going to find out more about how

our senses are connected

let's go

[Music]

everyone knows we have five senses

sight hearing

taste smell and touch

we use our senses every day they help us

to understand the world around us

professor charles spence knows a lot

about the senses

he works at oxford university

he's a psychologist a scientist who

studies the mind

he's a specialist in the senses i'm an

experimental psychologist

working here at oxford university and

i'm interested in the senses

in hearing and vision and touch taste

pain and how those senses get put

together in people's heads

we hear sounds and we see color

but what would it be like to hear color

did you know that some people

actually do see sound or hear color

this is called synesthesia

their brains connect colors with sounds

or shapes

or even with different flavors

[Music]

scientists have known about synesthesia

for more than 200 years

but they haven't understood it very well

until recently

that's because now scientists have

machines that help us see how our senses

stimulate our brain

in the past they thought synesthesia was

very rare

now they know that about four percent of

people have the condition

[Music]

even people who don't have synesthesia

often make connections between the

senses

[Music]

psychologists call this multi-sensory

perception

and experts like professor spence are

studying it and learning more about it

you're trying to understand the rules

that connect your eye to your ear

your ear to your nose your nose to your

mouth

the sensory cortex is the part of the

brain that deals with the senses

each sense has its own separate area for

people with synesthesia

there is a connection between two

different areas this allows some people

to hear color

or see sound we have

five senses or perhaps more hearing

vision touch

taste and smell and most of the time

when we experience the world or products

around us they stimulate most not all

of the senses dr spence believes that we

often use our senses together

eating in a restaurant or choosing

things in the supermarket

so take a lovely meal that's going to

taste right you should have the right

aroma or smell it needs to look

visually appealing the crunch the sound

should be right as the texture the mouth

feel or the fattiness in the mouth

so all the senses are involved in the

perception of food

and that may be the most multi-sensory

of our experiences

[Applause]

professor spence is working hard to

understand how the senses work together

his work is useful for the food business

if i think about uh some sort of

packaging or something say this bottle

here

it's got a certain weight it's got a

feel of roughness

so that's kind of it's also got a sound

i can hear

a color and it'll have a smell so all

the senses are again being involved

in my perception of this product and

it's packaging and

a lot of the work that we do with

companies now is trying to help them

enhance the multi-sensory appeal

of what they're offering today they are

testing how different music can affect

the taste of coffee

we understand the world through our

senses everything we experience

we experience through our sense of touch

taste

smell sight or hearing therefore

a better understanding of how the senses

work and how they work together

will lead to a better understanding of

the world we live in

you
