sensation and perception

Perception

A true representation of sensation, involving the organization and interpretation of incoming stimuli.

Sensation

A straightforward process of detection, defined as the stimulation of a sensory organ by external stimuli.

Threshold of Sensation

The minimum amount of stimulus required for detection, which varies depending on the individual and stimulus.

Weber's Law

States that experiences related to perception vary as a function of a constant ratio of the initial intensity of the stimulus.

"Black Hole" (in cognitive processing)

A term used to denote the unknown cognitive processing that transforms sensory inputs into perceptual outputs.

Mental Representation

A mental framework or category, such as the concept of a chair, that plays a role in transforming sensory inputs into perceptual outputs and differentiating objects.

Frontal Lobe's role in perception

Involved in decision-making and behavior during perception.

Parietal Lobe's role in perception

Processes sensory information during perception.

Temporal Lobe's role in perception

Implicated in auditory processing and memory during perception.

Occipital Lobe's role in perception

Responsible for processing visual stimuli, with the V4 area specifically processing color (e.g., gray).
