Chapter 5: perceiving objects and scenes Flashcards
what is the inverse projection problem?
a particular image on the retina can be created by many different objects
viewpoint invariance is the ability to:
recognize an object seen from different viewpoints
selective adaptation:
neurons tuned to specific stimuli properties fatigue with prolonged exposure to stimuli containing those properties
selective rearing:
raising animals in environments that contain only certain types of stimuli
the dorsal pathway tells us _____ and the ventral pathway tells us ________
where, what
cortical magnification refers to:
a small area of the fovea being represented by a large area on the visual cortex
IT neurons respond to more ____ stimuli than neurons in the striate
complex
the FFA has neurons which respond best to ____
faces
the medial temporal lobe (MTL) has structures important for _____
memory
specificity coding:
individual neurons respond to specific stimuli
population coding:
pattern of firing across many neurons coded to specific objects
sparse coding:
only a small number of neurons are necessary to code for each concept/identity
prosopagnosia is the inability to recognize ____ and is caused by damage to the _______
faces, temporal lobe
inversion effects
occur for stimuli that people have difficulty noticing unusual details in when turned upside down
perceptual organization:
the process by which objects in the environment get grouped together to create a perception of the environment
