UNIT 3 and UNIT 4 Flashcards
Neural convergence
firing rate depends on the amount of light stimulating the sensory receptors
grating stimulus
adaptation process where the difference in alternating bars can be barely seen
selective rearing
an animal which lives in a specific environment will have more neurons which respond to that specific environment
‘What’ pathway
objects identity in temporal lobe
‘Where/How’ pathway
object’s location or interaction in parietal lobe
Inverse projection problem
an image on the retina can be created by various objects
viewpoint invariance
we are able to recognize objects from different viewpoints
perceptual organization
how elements tend to group together
figure-ground segregation
how an object is separated from another
Pragnanz “good figure”
the structure as simple as possible
proximity
objects close together tend to be grouped
similarity
similar objects tend tobe grouped
good continuation
objects that if joined will give a straight or smooth curved line
common region
elements in the same region tend to be grouped together
uniform connectedness
connected region seem a single unit
synchrony
elements that happen at the same time tend to be grouped together
common fate
elements that move together in the same direction are believed to be grouped together
familiarity
familiar or meaningful objects tend to be grouped together
closure
fragmentary stimuli is completed
apparent movement
illusion of movement
illusory contours
illusion of contour by contrast of colors
bistable figures
stimuli that can be represented in 2 different ways
geons
geometric icons used to recognize objects
NAPs
properties of edges
semantic regularities
functions in scenes
theory of unconscious inference
using knowledge to infer what is present in a scene
Fusiform Face Area
perceives faces. Contains amygdala (emotions) // superior temporal sulcus (mouth movements) // frontal cortex (evaluating appearance)
extrastriate body area
perceives bodies
parahippocampal place area
perceives places
grill spector experiment
face and then mask and you are asked what you see
Tong and Coworkers experiment
One eye you see a house, other a face. When you see the house the parahippocampal place area is activated and when you see the face the Fusiform face area is activated
