exam 3 sensation and perception

oculomotor cues

cues based on eye movement

convergence

inward movement of the eyes when we focus on nearby objects

accomodation

shape of lens change for focus

monocular cues

can be seen with one eye

pictorial cues

available in pictures

motion parrallax

objects in distance move slowly and objects that are closer move faster

deletion and accretion

objects are covered and uncovered as we move relative to them

stereoscopic depth perception

depth perception that is created by the overlapping input from both eyes

binocular disparity

seeing a different image in each eye

blake and hirsch cat study

cats had few binocular neurons, were unable to use binocular disparity to perceive depth

emmert’s law

Retinal size of an afterimage remains constant, Perceived size will change depending on distance of projection

muller lyer illusion

Straight lines with inward fins appear shorter than straight lines with outward fins

conflicting cues theory

our perception of muller lyer line length depends on The actual length of the vertical lines and The overall length of the figure
