Ch. 8 Motion Perception

the illusion of motion of a stationary object that occurs after prolonged exposure to a moving object

retinal image movement or pursuit eye movement

deciding if its object or eye movement

no retinal image movement

velocity thresholds and basic/original visual capability

lowest motion speed at which we can perceive or highest motion speed at which we can perceive

phi phenomenon and stroboscopic motion

the illusory impression of smooth motion resulting from the rapid alternation of objects that appear in different location in rapid succession

knowing which feature in frame 2 corresponds to a particular feature in frame 1

relative displacement and enclosed objects

made of the magnocellular system, complex cells, and the medial temporal area

involves optic flow field and looming, and object moving across a background (perceive motions from objects in environment and interpret by brain, bottom-up theory)

collection of light rays that interact with objects in the world that are in front of a viewer

changing angular positions of points in a perspective image that we experience as we move through the world

signal sent to comparator to inform that the eye has moved

retinal image movement and a corollary discharge signal

pattern of movement of living beings (humans and animals) clues to biological status, gender, and activity

how to define an objects shape and be able to segregate an object from its background

voluntary eye movement in which the eyes move smoothly to follow a moving object

an involuntary, small, jerklike eye movement

conscious movement of eyes from one direction to the next, takes roughly 250 milliseconds to take effect
