Perception

HideShow resource information
Perception
The way the brain makes sense of the visual image detected by the eyes.
1 of 30
Retina
The light-sensitive layer at the back of the eye. It is made up of nerve cells called rods and cones.
2 of 30
Rods
Light-sensitive cells in the retina that respond even in dim light.
3 of 30
Cones
Light-sensitive cells in the retina that can detect colour.
4 of 30
Optic nerve
Bundle of nerve cells that leads out from the retina at the back of the eye. It carries information from the rods and cones to the brain.
5 of 30
Blindspot
The area of the retina where the optic nerve leaves. It has no rods or cones so cannot detect light.
6 of 30
Optic chiasma
The cross-shape where some of the information from the left and right eye crosses over to pass into the opposite side of the brain.
7 of 30
Visual cortex
The area at the back of the brain that interprets visual information.
8 of 30
Depth cues
The visual 'clues' that we use to understand depth or distance.
9 of 30
Monocular depth cues
Information about distance that comes from one eye, such as superimposition, relative size, texture gradient, linear perspective and height in the plane.
10 of 30
Binocular depth cues
Information about distance that needs two eyes, such as stereopsis.
11 of 30
Size constancy
We perceive an object as the same size even when its distance from us changes.
12 of 30
Relative size
Smaller objects are perceived as further away than larger ones.
13 of 30
Texture gradient
An area with a detailed pattern is perceived to be nearer than one with less detail.
14 of 30
Height in the plane
Objects closer to the horizon are perceived to be more distant than ones below or above the horizon.
15 of 30
Superimposition
A partly hidden object must be further away than the object covering it.
16 of 30
Linear perspective
Parallel lines appear to converge (meet) in the distance.
17 of 30
Stereopsis
A binocular cue to depth. The greater the difference between the view seen by the left eye and the right eye, the closer the viewer is looking.
18 of 30
Figure - ground
A small, complex, symmetrical object (the figure) is seen as separate from a background (ground).
19 of 30
Similarity
Figures sharing size, shape or colour are grouped together with other things that look the same.
20 of 30
Proximity
Objects which are close together are perceived to be related.
21 of 30
Continuity
Straight lines, curves and shapes are perceived to carry on being the same.
22 of 30
Closure
Lines or shapes are perceived as complete figures even if parts are missing.
23 of 30
Fiction
An illusion caused when a figure is perceived even though it is not present in the stimulus.
24 of 30
Illusory contour
A boundary (edge) that is perceived in a figure but is not present in the stimulus.
25 of 30
Motion after-effect
An illusion caused by paying attention to movement in one direction and perceiving movement in the opposite direction immediately afterwards.
26 of 30
Colour after-effect
An illusion caused by focusing on a coloured stimulus and perceiving opposite colours immediately afterwards.
27 of 30
Visual illusion
A conflict between reality and what we perceive.
28 of 30
Ambiguous figure
A stimulus with two possible interpretations, in which it is possible to perceive only one of the alternatives at any time.
29 of 30
Distortion illusion
Where our perception is deceived by some aspect of the stimulus. This can affect the shape or size of an object.
