Motion Perception
The phenomenon where a highly salient stimulus automatically draws attention
What is attentional capture?
The distribution of light energy across different wavelengths
What is spectral power distribution?
The process by which the lens changes shape to focus on objects at different distances
What is accommodation?
The perception of motion when no actual movement occurs, such as in movies.
What is apparent motion?
The term for the vividness or purity of a color
What is saturation?
A type of depth cue that can be perceived with one eye alone
What is monocular cue?
The illusion of motion in the opposite direction after viewing a moving stimulus
What is motion aftereffect?
The process of mixing lights of different wavelengths to create new colors
What is additive color mixture?
The pictorial cue where one object partially hides another, indicating the hidden object is farther away
What is occlusion?
The term for the visual system’s mechanism that compares signals from the retina and eye movements to perceive motion
What is comparator?
This principle explains the inability of a single photoreceptor to distinguish between wavelength and intensity
What is principle of univariance?
The depth cue where distant objects appear hazier and bluer due to the atmosphere
What is atmospheric perspective?
The problem of determining motion direction when viewing an object through a small aperture
What is aperture problem?
The principle stating that the ratio of light reflected from two surfaces determines perceived brightness
What is the ratio principle?
The inward movement of the eyes that occurs when focusing on a nearby object
What is convergence?
