chapter 5 Flashcards
1
Q
bottom up processing
A
- physical stimuli influences how we percieve them
2
Q
top down processing
A
- existing knowledge of objects influences how we perceive them
3
Q
recognition
A
- ability to match a currently viewed item with an item in memory
- perceptual matching of something currently present to our visual system with a stored representation in memory
4
Q
representation
A
- process translating stimulus information into a perceptual experience of that stimulus
5
Q
perceptual organization
A
- multiple objects in the environment are grouped allowing us to identify multiple objects in complex scenes
6
Q
grouping
A
- elements in a figure are brought together into a common unit or object
7
Q
segregation
A
- process of distinguishing 2 objects as being distinct or discrete
8
Q
figure ground organization
A
- experience viewers have as which part of an image is front and which part of an image is in the background of a scene
9
Q
gestalt laws of perceptual grouping
good continuation
A
- smooth edges, more likely to be seen as continuous
10
Q
gestalt laws of perceptual grouping
law of proximity
A
- elements close together are seen as a unified group
11
Q
gestalt laws of perceptual grouping
law of similarity
A
- elements that are similar are seen as a unified group, any similarity
12
Q
gestalt laws of perceptual grouping
law of symmetry
A
- elements symmetrical perceived as a unified group
13
Q
gestalt laws of perceptual grouping
law of common fate
A
- elements moving together seen as a unified group
14
Q
edge completion
A
- perception of a physically absent but inferred edge, complete the perception of a partially hidden object
15
Q
perceptual interpolation
A
- being able to see an object as a whole even if it is partially obstructed
16
Q
illusory contours
A
- perceptual edges that exist because of edge completion but are not physically present
17
Q
geons
A
- basic units of objects, consisting of simple shapes such as cylinders and pyramids
18
Q
recognition by components
A
- theory stating object recognition occurs by representing each object as a combination of basic units (geons)
- we recognise objects by geons
19
Q
viewpoint invariance
A
- an object does not change when the observer sees the object from a new vantage point
20
Q
V4
A
- area of the brain involved in color vision and shape perception
21
Q
inferotemporal area
A
- area of the temporal lobe involved in object perception, recieves input from V4 and other areas in the occipital lobe
22
Q
fusiform face area
A
- area in the inferotemporal area of the temporal lobe that specializes in recognising familiar faces
