2.1.B—Explain how visual perceptual processes produce correct or incorrect interpretations of stimuli

Explain how visual perceptual processes produce correct or incorrect interpretations of stimuli.

• Binocular depth cues of retinal disparity (the difference between the images projecting onto the retina) and convergence (the merging of the retinal images by the brain) utilize images from each eye to provide perception of depth.
• Monocular depth cues (relative clarity, relative size, texture gradient, linear perspective, and interposition) give the illusion of depth on flat or two-dimensional surfaces.
  • Exclusion: The AP Psychology Exam will only address the listed monocular depth cues in EK
• Visual perceptual constancies maintain the perception of an object even when the images of the object in the visual field change.
• Apparent movement can be visually perceived even when objects are not actually moving.
