Exam 4 (Part 3) Perceptual Constancies Flashcards
1
Q
Perceptual constancies
A
- Helps us see things as the same even if they appear to be changing
- Allows us to recognize familiar stimuli under varying conditions
2
Q
Size constancy
A
- Changes in size of a retinal image is interpreted as changes in distance
- Not changes in the actual size of the stimulus
3
Q
Shape constancy
A
- The perceived shape of an object remains the same, even when seen at different angles
4
Q
Brightness/Color constancy
A
- Brightness or color of object remains the same under different conditions of illumination
5
Q
Depth perception
A
- Distance between objects
- How far or near away objects are
- Two types of cues
6
Q
Binocular depth cues
A
- Require use of both eyes
7
Q
Eye convergence
A
- Produced by feedback from the muscles in your eyes
- Eyes rotate inward to view a close object or project it onto the retina
8
Q
Binocular disparity
A
- Also called retinal disparity
- Each eye sees slightly different image
- Slightly different viewing angle in each eye
9
Q
Monocular depth cues
A
- Cues about distance that requires only one eye
10
Q
Pictorial depth cues
A
Cues about distance that can be given in a flat picture
11
Q
Linear perspective
A
- Perception that parallel lines converge in the distance
12
Q
Interposition
A
- Also called superposition
- Objects closer to us may cut off parts of our view of more distance objects
13
Q
Elevations
A
- Height in plane
- Height on the horizontal plane
14
Q
Texture gradient
A
- Closer objects have greater detail
15
Q
Relative size
A
- If two objects are (thought to be) of similar size
- The one that looks smaller
- Will be judged to be farther away
