Document Summary

> neural messages based directly on sensory input. > application of expectations & prior knowledge in the organization & interpretation of sensory input. > how sensory input is interpreted can also vary as a function of how the input is organized. > detection of light energy that reflects off objects & surfaces & travels in waves. > the eye detects waves of electromagnetic radiation (light energy) that reflect off of objects & surfaces. > wave length combinations give rise to color complexity. > 3 types of cones in the retina are sensitive to different wavelengths of light. > support of this theory comes from dichromatism. > genetic variation that results in one or more cone types to be missing. > the firing rate of opponent-process cells in the retina, thalamus, & visual cortex increases is inhibited in response to some wavelengths & triggered by others. > support of this theory comes from negative after-image.
