Motion Flashcards
what are 5 types of motion
ego-self motion object motion apparent motion biological motion motion parallax
what is ego motion
motion induced by movement of observer or optic flow
what is object motion
motion induced by movement of objects
what is apparent motion
when stationary objects appear to move
e.g. flipbook
what is biological motion
specific motion pattern of living things- stickmen dots
what is motion parallax
depth from motion
close objects move faster etc
how do u build a motion detector
two adjacent receptors separated by distanc
induces a delay line in first detector as object pass second detector
what are two problems with motion detectors
correspondence and aperture
describe correspondence problem for motion detecotr
faced by motion detection system of knowing whihc feature at time 2 corresponds to feature at time
describe aparture problem for motion detecton
fact that moving object is viewed through an aperuture direction of motion of local feature may be ambiguius
what is motion afteraffect
illusion of motion of stationary object that occurs after prolonged exposure to moving object
existence of motion after implies opponent processing
what is interocular transfer
transfer of an effect -adaptation- from one eye to the other
what was Newsome and Pares experiment
trained monkeys to respond to dot motion displays
injection of neurotoxing in MT area- increased motion threshold- monkeys needed more dots
what is akinestopia
rare disorder where indivua has no perception of motion
what cause akinetopia
caused by disruption to MT
