welcome everybody
my name is shovron i'm a professor in
turbo university and i teach cognitive
psychology
and i want to share you some insights in
what we what you get when we give our
first lectures in psychology
so um what is cognitive psychology
called
psychology is
a core discipline in psychology it means
wherever you go you will teach it will
be taught
and it's really about the basic
components of our mind we think about
memory about attention learning
perception and so forth these are all
basic elements of our mind that
determine how we can behave
intelligently in the world
now i want to show you some insights in
what we have when we teach on in this
case perception
now you probably all know when you were
a kid that
well we basically have five senses at
least that's the rumor
what are those senses well you know them
you see you have the eyes for seeing the
ears for hearing nose for smelling and
so forth
so that's the basic thing that people
know
what people often don't know is that
actually we have much more senses than
those five
some people may say you know i have a
sixth sense
but really we have more than six also so
for instance friends think about balance
feeling vibration we have senses for
temperature pain and also kinesthesia
that's about how you move your arms in
the tension on the muscles and so forth
these all are part of our perceptual
system
and they are
and if we count well we we may have
about 12
to 15 cents different centers okay
that's lesson one from psychology
lesson two from psychology is comes from
neuroscience
we all know that
each of those senses they have a
dedicated brain area to which they
project
so we have visual information for the
visual cortex
the auditory cortex is for audrey
perception and so forth
now these
cortical areas in the brain
are indispensable for
seeing hearing and so forth
imagine somebody has a brain tumor in
visual cortex
they may suffer from cortical blindness
so those people there their eyes are
fine but yet they don't see well and the
same for hearing dumbness and so forth
so
so far so good
however
there is more than that first of all i
should say we know an awful lot about
how this information in these primary
cortical areas is processed
but there is a bit more
it is more complex than that
rather the sum perception
is much more than the sum of the
activities in these cortical areas
now
what do i mean with that
take for instance a simple example which
the dutch are very
happy with and that is with french fries
now
simple question when do french fries
actually taste well
well
taste you may say that has to do with
tongue and mouth
and so yes indeed they should be a bit
salty and they should be fatty and they
should also preferably a bit taste like
potatoes
but there's more than that they should
also smell like potatoes so smell yes
it's important as well it kicks in also
are we there no they should also look
like french fries so you don't want them
to be blue or green but rather they
should be golden brown
are we there yet
no they should also be crispy now and
crispy is a really difficult one because
it has to do with muscle tension
and at the right tension it should crack
and the cracking is about hearing
so it's really important that you they
crack
on exactly the right time
okay so we already have motor cortex
auditory cortex visual cortex
somatosensory cortex
taste cortex are we there yet
no they should also be hot of course and
that's temperature that's again
different senses
and
is that fine
i'm sorry we also need pain
and pain because they should be sizzling
hot and sizzling hearts how is that
coded in the brain it's pain
so again different sensors kick in just
for this single french fry
are we there yet
no the dutch it's really about the
mayonnaise french fries are only an
excuse to have mine eat mayonnaise and
mayonnaise again well that should be
creamy white
cold
and so forth so we get a really complex
innervation here of different sensors
to get good fry
so a single percent like the taser fry
depends on many many senses
okay
this cooperation between the senses you
may think you made that up but it's
actually
always the case so here i have
another example taken from visual
stability
now imagine you look at the right side
of this video and what you see there is
a bee
we're sitting still
now you also see this little squat
circle there what is that that's what
the eyes are actually looking at so we
can look with
eye trackers where the subject is
looking and here we have a free
recording of a subject
just looking at
this image
now what's on the left side of the image
well this is what actually the
information that is sent to the visual
brain from the eyes so on the left side
what you see there is a small circle
where the subject is looking
and that's the information
sent to the brain
and the brain now
has to figure out from this information
on the left
what's actually in the image on the
right
and so what you see there eyes are never
still
they always move
in fact if your eyes would be stable
completely still you would be blind in
two seconds because
the the receptors adapt very quickly so
this
very jiggling moving is very important
to see otherwise you would be blind
but imagine what the visual cortex has
to do to figure out what's this wibbling
image to make a stable image
and the basic objective of this is the
visual cortex needs to know where the
eyes are looking so it needs to and it
gets this information from motor areas
so motor areas they don't just talk to
the eyes
but also to the visual cortex to tell
where they're looking at otherwise we
couldn't come up with a stable image
so that's another example of where
senses cooperate
here
another example from
how we stabilize our head
we have a chicken here and actually you
should hear nice music
from diana ross upside down but in the
meantime
figure out how it just imagine how it
might sound but here we have a chicken
that is moved
and the interesting part of this you see
lots of chickens here they're all moved
but
look how they stabilize their head so
wherever you move
the chicken stabilizes her head how does
she know that well because there are
sensory information about where i'm
moving and that's
tell that scent towards the head and the
motor system to move and actually
an an interesting
motor company they might use that
information to stabilize their car so
this was actually an ad from
mercedes-benz
so
is when this does this develop this
integration between the sensors
well here is an example of coolant melts
up they did that long time ago they had
babies
sitting in a rocking chair
and those babies they could see two
videos of a speaker
one speaker said ah
ah so they moved her mouse like ah and
the other speaker said e
e
e
now
the baby can look at the both videos and
just wondering what's going on but at
some point they hear
ah
ah and what does the baby do he
immediately looks at the face that's
pronouncing r and if the baby hears e
e
he starts looking at the face that says
e
so we have here the baby knows already
how sounds should be articulated he
knows about r and e
now what's interesting about this
phenomenon
is that the baby is only four months old
he hasn't spoken yet
and
so the baby has no knowledge in
principle of what our knee sounds does
yet he knows where to look at how they
should be articulated so long before
babies can talk they already know about
how we move
our mouth and how what sound it should
produce
again another demonstration that eyes
and ears are strongly connected
so
all these examples demonstrate that
information from different centers get
integrated with each other
but
also realize that all sensors
continuously transform transmit
information to the brain
so while you're watching me
you feel your shoes you may hear your
mother in the background and so forth so
how does the brain then actually know
which information belongs together
and which not
how do you know that the sounds that you
hear are related to the movements that
you see here
but not let's say to the to the to the
screen to the other part of the screen
that you're looking at
now that's a difficult question
we've solved this problem it's known as
scene analysis
what is scene analysis
it it's your cameras nowadays are smart
they not just take a picture
but they actually recognize that this is
the microphone that that's a video
camera and that's this is your face
how do they do that in the visual system
because they're also
how do you know what belongs together
and what not and in for the visual
system we've discovered various kind of
laws and here i show you one law
this is look at this picture and just
try to figure out what it is
now this may be difficult and you may
have to look at it for a while and still
don't know what it is
but now watch it i will ruin your brain
because i'll tell you what it is and
from now on you will always see it
immediately because
now you see now you discover weight
these are
covered by circles a b
c d
but now look at the black parts
the black parts on the left the ladders
and the black parts on the right
are identical
why is it that you see it on the right
side but not on the left side
now
the reason
why it is
is because there is a law in scene
analysis which says that boundaries
belong to objects
now
what does it entail for instance take
this little path here
that part in the left side
was difficult
you thought your visual system thought
it belongs to the letters
but once we covered it with circles
there is this rule which is
no no no that critical part there is
actually not from the ladder ignore that
because it's from the circle
and so that's noise
and this is whereas this part the other
part on the left here that is now
critical for the letter c
so this rules now tells us what the
characteristics of a circle is and which
to ignore it separates signal from noise
that is what scene analysis does
okay
but
how does the brain then know
for the multi-sensory domain
so here we also have many senses
bring sending information to the brain
and how does the brain know which
information belongs together yes or no
so here we have an example of clapping
hands imagine i do this
right so i have my motor system which
says i'm moving my hands
my auditory system says i hear a clap my
visual system sees something and then it
suddenly stops
but i also see lambs here a microphone
here and so forth
how do we know that this belongs
together and the other part should be
ignored
well
what do hearing
seeing and feeling have in common then
well for one and that's for sure they
arrive at approximately the same time in
the brain
and so there is differences in neural
processing time and in transmission time
of vision and addition but they arrive
at about the same time in the brain and
that is for the brain a very good cue to
tell
this is no coincidence
we should take that together they belong
together
but
they may also
come from the same location because we
can hear where the sound comes from you
know where your hands are and the visual
system knows about the location
so maybe it's also a location that is a
cue which tells you
this all comes from the same location
treat them together
or
you may also have learned
in due course of development how
clapping hands sound so they sound like
flesh on flesh and not something like
like this and you may learn by
association from memory that they should
belong together yes or no
all these properties may play a role but
we in our university are looking at many
other different aspects of scene
analysis in the multi-sensory domain
that's what i had to say my friends hope
to see you soon at dilberg university
yeah we can stop the recording
i can just
click here
and

welcome everybody
