Psyc/Biol 240 - Exam 4 Review Terms


These terms and phrases are provided as a study aid. You should know what they mean and how they are relevant to vision/perception, but you should not rely on this list as your only (or even primary) study aid. Of far more value is the lecture outline for this section of the course, which you can get to from the Section 4 - Course Material for Exam 4 page.

DEPTH PERCEPTION
- oculomotor depth cues: convergence and accomodation
- pictorial monocular depth cues: Interposition (occlusion), relative size/familiar size, linear perspective, texture gradient, atmospheric perspective, shading
- movement cues: motion parallax, deletion and accretion
- stereopsis, binocular depth cues: retinal disparity, angle of disparity, crossed vs. uncrossed disparity, horopter, corresponding vs. non-corresponding points
- What do random-dot stereograms tell us about how stereopsis is accomplished by the visual system?
- disparity selective cells: What sort of information are they sensitive to?
- development of depth perception
- What are amblyopia and strabismus?? What happens if problems are not corrected early in development?
- size constancy, size-distance scaling (Emmert's Law), Holway & Boring experiment
- depth illusions: moon illusion

MOTION PERCEPTION
- motion pathways in the brain, magno, MT, MST?
- functions of movement in perception
- What are the different functions of the image-retina and the eye-head systems?
- image-retina system: motion and direction selective neurons (How do they work?), factors affecting the firing of movement detectors, perceptual evidence for movement detectors, apparent movement
- eye-head system (corollary discharge theory): 3 signals, how are movements of the eyes and head compensated for in motion perception?
- three types of eye movements (saccade, pursuit, vestibular)
- perception of structure from motion (kinetic depth effect), biological motion
- Visual guidance of movement: How do we maintain heading and judge our time of arrival?; optic flow, focus of expansion, locomotor flow line, rate of angular expansion
- effects of movement on balance
