perception Flashcards
(24 cards)
sense
physical properties/environment -> currency/electric impulse
illusion
input is not what we experience
parallel line -> not really parallel line
perception
organising
interpreting
making sense of the input
reflect beliefs what real + exists
problem of qualia
currency: neuron structure similar
how do brain know wht cause stimuli it receive
how do it separate the signal they receive
brain can mix up signal -> synesthesia
one trial learning
know pattern once cannot unseen it
importance illusion
show brain active make sense
visual goes beyond input
general rules that visual extract information in environment
dimensionality reduction
in taste
- lots of chemical stuff
-> want to distinguish if certain food contain more type of which chemical
-> simplify it to simple class of events
taste have 5
papillae
bump
tongue
3/4 have taste receptors
filliform doesnt have taste receptors
sweet
energy,
less sensitive
by smell
umami
not in rank sensi
amino acid, msg, can taste by tongue
salt
electrolyte balance
more sensi than sweet 2x
sour
acid, too high = dangerous
-> way more sensitive to this
bitter
potential poison, more more sensitive
taste localise in tongue
wrong
labelled line
each receptor receive certain type of taste
eg bitter receptor response to bitter and transfer info to brain
non-taster
less sensi
-> food need to have lots of flavour
supertaster
sensitive to flavour
women
less coffee fatty food
asian african
spicy
not taste
pain + temperature
from chemosensory irritation
spicy receptor
trigeminal nerve
olfaction
smell
pattern shape theory
smell like chemical molecular
lock and key
chemical shape comes bind into receptors
-> know what the molecular is
prob olfaction theory
same shape different smell
same smell different chemical shape
flavour
taste smell temperature
adaptation
always adapt to own smell, sensitive with other smell
