Question

Quizplus · Accepted Answer

The description matches the trichromatic theory, which proposes that there are three types of cone cells in the eye that are each sensitive to a different range of wavelengths.

Answer: D
 The opponent-process theory proposes that there are three pairs of opposing color channels in the visual system, with each pair being sensitive to either red versus green, blue versus yellow, or black versus white.

Answer: A
 Signal-detection theory deals with the ability to distinguish meaningful sensory stimuli from background noise.

Answer: C
 Gate-control theory deals with how pain signals are processed in the spinal cord and how they can be modulated by factors such as attention and emotion.

Answer: B
 Gestalt principles deal with how people perceive and organize visual stimuli into meaningful wholes, based on concepts such as similarity, proximity, and closure.
