Lecture 13 Flashcards
Motion and Depth Perception (13 cards)
What is real motion?
Actual physical movement of objects.
What is apparent motion?
Perception of movement from static images shown in succession.
What is induced motion?
Motion of one object causes a nearby stationary object to appear moving.
What is the motion aftereffect?
Illusion of motion in the opposite direction after watching movement.
Which brain area processes motion?
Middle Temporal (MT or V5) area.
What is akinetopsia?
Motion blindness caused by damage to area MT.
What are microsaccades?
Tiny eye movements that prevent image fading on the retina.
What is motion parallax?
Nearby objects move faster across the visual field than distant ones.
What is binocular disparity?
Difference in retinal images that helps with depth perception.
What is stereopsis?
Depth perception from binocular disparity.
What is convergence?
Inward movement of eyes when focusing on a close object.
What is the visual cliff?
An experiment showing infant depth perception.
What is pictorial depth?
Monocular cues like texture gradient, perspective, occlusion.
