Document Summary

Explain how sensation and perception are the same, and how they are different. Compare structuralist, gestalt, and constructivist (knowledge-based accounts) of perception. Describe the gestalt principles contributing to visual perception. Explain the psychophysical concepts of just noticeable difference, difference thresholds, and absolute thresholds. Explain how signal detection theory differentiates sensitivity and bias. Describe how the psychological attributes pitch, loudness, and timbre are coded in the auditory system, and the physical characteristics of sounds to which they correspond. Describe the cues contributing to visual depth perception. Contrast the functions of the dorsal and ventral streams of cortical processing in vision, and describe visual perceptual disorders that result from damage to different brain regions. Describe lateral inhibition and its role in helping the brain find edges" of objects. Describe the concept of the receptive field and how receptive fields contribute to perception. Describe how perception of a visual object differs from the raw retinal image.
