2nd Lesson - Perception Theory

A collection of vocabulary flashcards based on key concepts in perception theory and gestalt psychology from the lecture notes.

Gestalt theory

The nervous system is predisposed to respond to patterns of sensory stimuli through innate mechanisms according to principles of perceptual organization.

Proximity

Elements placed close together are perceived as related and grouped by our visual system.

Similarity

Similar elements tend to be perceived as grouped together based on visual characteristics.

Closure

The mind tends to fill in gaps, perceiving incomplete shapes as complete entities.

Continuity

We perceive lines and shapes as continuous, following the simplest paths.

Symmetry

Objects that are balanced and symmetrical are perceived as complete and whole.

Common Fate

Elements moving in the same direction and speed are viewed as parts of a single object.

Figure-ground

The perceptual tendency to distinguish a main object from its background.

Perceptual Constancy

Our perception of objects maintains certain characteristics despite changes in stimuli.

Color Constancy

The tendency to perceive an object as having the same color under varying lighting conditions.

Visual Illusions

Perceptions that misrepresent physical reality, highlighting the complexities of our visual processing.

Perceptual Ambiguity

Images that can be interpreted in multiple ways based on perceptual cues.

Law of Good Form (Prägnanz)

We tend to perceive visual reality in the simplest, most stable, and symmetrical forms possible.

Size Constancy

The perception that an object is the same size regardless of changes in distance.

Shape Constancy

The perception that an object maintains the same shape despite changes in viewing angle.
