Ch 4 Lecture on Perception and Gestalt Principles

These flashcards cover key concepts on perception as discussed in the lecture notes, focusing on Gestalt principles, perception mechanisms, and optical illusions.

Gestalt Principles

Psychological concepts that emphasize that the whole is greater than the sum of its parts in perception.

Perceptual Constancy

The tendency to perceive objects as unchanging despite changes in sensory input.

Distal and Proximal Shapes

Distal refers to objects far from the observer, while proximal refers to objects close to the observer as they are perceived.

Retinal Disparity

The difference in images between the two eyes, which allows for depth perception.

Monocular Cues

Depth cues that require only one eye, such as size, texture, and perspective.

Müller-Lyer Illusion

An optical illusion that shows how the length of a line can be perceived differently based on the direction of arrowheads at its ends.

Enclosure Principle

The idea that objects are perceived as grouped together if they enclose an area.

Parallel Lines

Lines that never converge, no matter how far they are extended.

Binocular View

The visual perception resulting from both eyes working together.

Perception of Color

Influenced by the relationships and contrasts of colors around an object.
