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
