-
What is motion aftereffect?
the illusion of motion of a stationary object that occurs after prolonged exposure to a moving object
-
How is visual ambiguity determined?
retinal image movement or pursuit eye movement
-
What is retinal image movement?
deciding if its object or eye movement
-
What is pursuit eye movement?
no retinal image movement
-
What is real motion?
velocity thresholds and basic/original visual capability
-
What are velocity thresholds?
lowest motion speed at which we can perceive or highest motion speed at which we can perceive
-
What is involved in apparent motion?
phi phenomenon and stroboscopic motion
-
What is apparent motion?
the illusory impression of smooth motion resulting from the rapid alternation of objects that appear in different location in rapid succession
-
What is the correspondence problem?
knowing which feature in frame 2 corresponds to a particular feature in frame 1
-
What does induced movement involve?
relative displacement and enclosed objects
-
What is the motion detection system?
made of the magnocellular system, complex cells, and the medial temporal area
-
What is the Gibson's theory of motion perception?
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)
-
What is optic array?
collection of light rays that interact with objects in the world that are in front of a viewer
-
What is optic flow?
changing angular positions of points in a perspective image that we experience as we move through the world
-
What is the corollary discharge theory?
signal sent to comparator to inform that the eye has moved
-
What must be present for object motion perception?
retinal image movement and a corollary discharge signal
-
What is biological motion?
pattern of movement of living beings (humans and animals) clues to biological status, gender, and activity
-
What does structure motion tell us?
how to define an objects shape and be able to segregate an object from its background
-
What is smooth pursuit?
voluntary eye movement in which the eyes move smoothly to follow a moving object
-
What is a microsaccade?
an involuntary, small, jerklike eye movement
-
What is a saccade?
conscious movement of eyes from one direction to the next, takes roughly 250 milliseconds to take effect
