Sensation and Perception

Flashcards covering key concepts of sensation and perception, including definitions, theories, and important terms.

Sensation

The process of detecting a stimulus in the environment through our five senses.

Perception

The organization and interpretation of sensory information by the brain.

Difference between Sensation and Perception

Sensation is the 'feeling' or detection of stimuli, while perception is the 'thinking' or interpretation of those sensations.

Gregory's Constructivist Theory

Proposes that perception is a combination of stimulus information and the brain's past experiences.

Gibson's Direct Theory

Suggests that sensation and perception are essentially the same, as the visual signals convey all the necessary information for understanding.

Sense Receptors

Cells in the senses (eyes, ears, nose, tongue, skin) that detect sensation.

Visual Signals

Characteristics of an object that help the brain understand its function and meaning.
