Intro Flashcards
what is gestalt psychology
the mind perceives an external stimulus as a whole rather than a sum of its parts
what is perceptual segregration
which are objects which are not
the retina geniculate striate system
the p & m pathway
what doe the p pathway
sensitive to colour and detail… impact from cones
m pathway …
sensitive to movement, input from rods
wwhere is the damage if the person has optic ataxia
dorsal pathway
what is problem when have optic ataxia
visual motions
what is akinetopsia
brain damage where stationary object are seen well but not moving ones
what is achromatopsia
little or no colour perception
normans 2002
dual process approach
what is the retnopic map
nerve sells occupying the same respective portions as their relative fields on the retina
what is the executive network
target detection
supervisoring control
what is the alerting network
maintaining focus over a period of time
what is orienting network
directed attention
3 operations : disengage, move, engage
implicityly processed stimuli?
noticed and unreported
explicitly processed stimuli
noticed and consciously assessed
lead to an over attentional shift
overt orientating
eye movements accompany attentional shifts
covert orientating
attentional shifts occur in the absence of eye movements
what network is exogeneous
ventral
what network is endogeneous
dorsal
what is the receptive field
the region of the retina where light influences the activity of a particular neuron
cognitive bottleneck theory
postponing the processing due to a bottleneck, impossible for appropriate responses to 2 different stimuli to be made simultaniously
V5 area?
MT - middle temporal, involved in motion processing
V4 area?
colour processing
V2 area
orientation, spatial frequencies
V1 area
specialised for processing information about orientaions and spatial frequencies
