Understanding Selective Attention and Depth Perception

Continuity

Perceiving continuous patterns rather than disjointed ones.

Figure Ground

Distinguishing figures from their background.

Depth Perception

Ability to perceive three-dimensional space.

Linear Perspective

Perceived distance increases with angle of convergence.

Texture Gradient

Monocular cue indicating depth through texture detail.

Selective Attention

Focusing on a specific stimulus while ignoring others.

Selective Inattention

Ignoring stimuli while concentrating on something else.

Change Blindness

Failure to notice changes in the environment.

Gestalt Principles

Rules for organizing visual information into wholes.

Grouping

Organizing stimuli into coherent groups.

Proximity

Grouping nearby figures together.

Similarity

Grouping similar items based on shared characteristics.

Closure

Filling in gaps to create complete objects.

Retinal Disparity

Difference between images from each eye for depth.

Monocular Cues

Depth cues available to one eye.

Interposition

Object blocking another is perceived as closer.

Relative Size

Smaller images are perceived as farther away.

Relative Height

Higher perceived objects are seen as farther away.

Shadow/Light Contrast

Shading creates a sense of depth perception.

Motion Parallax

Closer objects appear to move faster than distant ones.

Phi Phenomenon

Illusion of movement from adjacent lights blinking.

Color Constancy

Perceiving familiar objects as having consistent colors.

Size Constancy

Perceiving objects as the same size despite distance.

Shape Constancy

Recognizing shapes as constant despite changes in perspective.
