four

Question 1

dorsal stream

Answer 1

-info from the somatosensory cortex contributes to the dorsal stare by specifying the movement used for grasping target
-uses visual info to move the body through space, egocentric

Question 2

ventral stream

Answer 2

-info form the second somatosensory cortex contributes to the ventral stream
-providing info about object size, shape and texture
-scene analysis

Question 3

face cells

Answer 3

-cells that respond to different complex images
-certain cells that respond to particular faces
-consistent even if image is rotated, diff colour, size
-are cells more likely to respond because of familiarity or emotional?

Question 4

gnostic/grandmother cells

Answer 4

-local coding, all elements of an object broken down
-allows for excellent discrimination between objects
-complete patterns and allow for generalisation

Question 5

what are the negatives to gnostic/grandmother cells

Answer 5

can be susceptible to damage and therefor could result in not recognising things

Question 6

paredoilia

Answer 6

-presented with ambiguous info an your nervous system interprets it as something else

Question 7

critical goals of visual system info processing

Answer 7

-discrimination
-generalisation
-need to balance these two things

Question 8

dense encoding theory

Answer 8

-no gma cells
-many cells that represent your gma (hair, nose, eyes)
-firing of a pattern of cells

Question 9

dense encoding allows for

Answer 9

generalistaion

Question 10

the visual system needs to balance

Answer 10

local encoding and dense encoding

Question 11

what did Doris tsao do

Answer 11

made and ‘average face’
-created synthetic faces by manipulating average faces

Question 12

what was found from doris tsao study

Answer 12

-many cells active for a face , coding a particular feature dimensions
-shut down the single cell codes for a particular face theory
