Document Summary

Perception: how we understand the stimulus. Synesthesia: associating one sense to another ex. tasting a color. Psychophysics: measuring strength of and sensitivity to stimuli. Transduction: taking wavelengths of energy and turning them into something that we can understand. Vision: visible light spectrum: 400nm-700nm, theories of color (both correct), trichromatic. We can only process three colors: blue, green, and red. Most other mammals can process only two: opponent processing. The more you excite the cells through one color, the more you inhibit the opposite color. White black: depth, binocular disparities. Both eyes focus on the same thing; eye can measure depth by the angle at which both eyes look at the object: monocular cues (picked up mostly through experience) Linear perspective (parallel lines getting close together the further they are) Relative height (assumption based on knowledge of how big things are, like a mountain vs. a flower) Interposition (you compare things on whether one thing is in front of the other)
