L33 Psych 100B Study Guide - Final Guide: Occipital Lobe, Roygbiv, Trichromacy
Document Summary
Respond (fire action potential) only for very specific stimuli: some will fire if see horizontal but not vertical line, some will fire if see l but not for straight line. Learning and feature detectors: normal kittens have neurons in occipital lobe respond to diagonal lines, effects of contact lenses that only allow kittens to see vertical and horizontal (not diagonal lines) Remove prior to age of 3 months (can still develop) Remove after age of 3 months (can never see diagonal lines again) The spectrum of light: white light combination of all colors, roygbiv. Theories of color vision: do not know exactly how perceive color, trichromatic theory (young-helmholtz) 3 different photochemicals respond best to 3 primary colors (red, green, blue) Any color can be made from combination of primary colors. Cone type most responsive to red fires most. Cone types most responsive to green and blue fires less.
