chapter 5 Flashcards
(25 cards)
1
Q
bottom up processing
A
- physical stimuli influence how we perceive them
2
Q
top down processing
A
- existing knowledge of objects influences how we perceive them
3
Q
recognition
A
- ability to match a presented item with an item in memory
4
Q
representation
A
- storage/reconstruction of information in memory when that information is not in use
5
Q
perceptual organization
A
- multiple objects in the environment are grouped
- allows us to identify multiple objects in complex scenes
6
Q
grouping
A
- elements in a figure are brought together into a common unit/object
7
Q
segregation
A
- process of distinguishing 2 objects as being distinct/discrete
8
Q
figure ground organization
A
- ability to tell which part of an image is the front vs the background of a scene
9
Q
gestalt laws
good continuation
A
- edges that are smooth are more likely to be seen as continuous
10
Q
gestalt laws
proximity
A
- elements closer together are more likely to be seen as a unified group
11
Q
gestalt laws
similarity
A
- elements that are similar, more likely to be seen as a unified group
12
Q
gestalt laws
symmetry
A
- elements that are symmetrical, more likely to be seen as a unified group
13
Q
gestalt laws
common fate
A
- elements moving together, more likely to be seen as a unified group
14
Q
edge completion
A
- perception of an absent but inferred edge, complete perception of a partially hidden object
15
Q
illusory contors
A
- perceptual edges that exist because of edge completion but aren’t actually present
16
Q
geons
A
- basic units of objects, simple shapes
17
Q
recognition by components
A
- theory, object recognition occurs by representing each object as a combination of geons that make up the object
18
Q
viewpoint invariance
A
- perception that an object doesn’t change when an observer views the object from a new vantage point
19
Q
V4
A
- area of the brain involved in color vision and shape perception
20
Q
inferotemporal area
A
- area of the temporal lobe involved in object perception
- receives input from V4 and other areas in the occipital lobe
21
Q
fusiform face area
A
- area in the inferotemporal area of the temporal lobe
- recognising familiar faces
22
Q
occipital face area
A
- area of the brain in the occipital lobe
- recognising faces as distinct from other objects
23
Q
parahippocampal place area (PPA)
A
- area within the inferotemporal cortex
- scene recognition
24
Q
topographic agnosia
A
- deficit in recognising spacial landscapes
- damage to PPA
25
extrastriate body area
- area within the inferotemporal cortex
- recognising body parts/bodies but not faces
