CERTIFICATION TEST BANK WITH VERIFIED
ANSWERS GRADED A+
⫸ visual perception cortex - occipital
⫸ ventral pathway of perception - what; occipital to temporal
⫸ pathways of perception: Mishkin monkey lesion study -- what are
monkeys doing? - object/landmark task
⫸ object/landmark task - pathways of perception: Mishkin monkey
lesion study; selecting foodwell based on either identity of object or
location of landmark
⫸ landmark task - pathways of perception: Mishkin monkey lesion
study; choose foodwell next to landmark
⫸ object task - pathways of perception: Mishkin monkey lesion study;
choose object that hides reward
⫸ pathways of perception: Mishkin monkey lesion study -- IV - task
(object or landmark), lesion location (dorsal or ventral)
,⫸ pathways of perception: Mishkin monkey lesion study -- DV -
accuracy on two tasks
⫸ pathways of perception: Mishkin monkey lesion study -- can you test
brain activity? - no, would be 0 in areas of lesions
⫸ dorsal lesions location - parietal
⫸ ventral lesions location - temporal
⫸ pathways of perception: Mishkin monkey lesion study -- monkey
with dorsal lesions results - performs well on object task but poorly on
landmark
⫸ pathways of perception: Mishkin monkey lesion study -- monkey
with ventral lesion results - performs well on landmark task but poorly
on object
⫸ pathways of perception: Mishkin monkey lesion study -- conclusions
- dorsal pathway necessary for perceiving where something is; ventral
necessary for perceiving what
⫸ pathways of perception: Mishkin monkey lesion study -- example of
what concepts? - independence (double dissociation) and necessity
(lesion study)
,⫸ optic ataxia - can recognize objects but cannot use visual information
to guide actions; damage to fine motor coordination
⫸ optic ataxia associated with lesions in which cortex? - parietal
⫸ dorsal neurons receptive fields - non-foveal
⫸ damage to dorsal pathway leads to what? - optic ataxia (inability to
coordinate to a specific location)
⫸ ventral neurons receptive fields - always encompass the fovea
⫸ Slot task with agnostic patients results - Cannot orient hand so the
card fits into the slot (deficit in perception); could insert the card into the
slot -- shape and orientation information was not available to the
processing system for object recognition, but it was available for the
visuomotor task (action system has access to information about
orientation)
⫸ Slot task with agnostic patients conclusions - "perceived" information
may not be available to all processing systems in the brain
, ⫸ Slot task with agnostic patients is an example of what concept? -
single dissociation -- selective impairment in using vision to recognize
objects while remaining proficient in using vision to perform actions
⫸ damage to ventral pathway results in what? - visual agnosias
⫸ pathway to object recognition - early vision (sensation and
perception) --> shape encoding (perception) --> object matching
(recognition)
⫸ what type of study used to study shape encoding? - human PET
⫸ shape encoding: Kanwisher human PET study -- what are participants
doing? - viewing scrambled, familiar, or novel stimuli
⫸ shape encoding: Kanwisher human PET study -- IV - type of stimulus
(familiar, novel, scrambled)
⫸ shape encoding: Kanwisher human PET study -- DV - Brain activity
(for whole shapes vs. parts)
⫸ shape encoding: Kanwisher human PET study -- familiar condition
has which of the following: feature extraction, shape encoding, memory
matching? - all
