Are You Colorblind?

Perception How do sensations become perceptions?

Perceptual Constancy Objects maintain their size, shape, color, and other properties despite changes in their retinal image. Allows experience where solid objects do not continuously change

Misperceiving Reality Which Line Is Longer?

Impossible Figures

Magic Eye

Motion

Perception of Motion Looming stimulus (rapid expansion) Images moves, but eyes and head do not Image moves, but can’t be caused by movement of the body, eyes, or head. –Visual flow without appropriate sensations can result in motion sickness. Stroboscopic Motion

Recognizing the Perceptual World How do I recognize familiar people?

How Does Recognition Occur? Bottom-Up Processing: Basic features of the stimulus are analyzed to create the perceptual experience. Top-Down Processing: Reliance on one’s knowledge, especially when sensory information is vague or ambiguous.

What Can Influence Top-Down Processing? Schemas –Readiness to perceive a stimulus in a certain way Motivation Expectancy or prior context

Expectancy

Organizing the Perceptual World What determines how I perceive my world?

Principles of Perceptual Organization: Figure and Ground Figure: The part of the visual field that has meaning. Ground: The contourless part of the visual field.

Gestalt Grouping Stimuli are grouped together “Gestalt” is the German word meaning (roughly) “whole figure.”
