PSYCH 1XX3 Chapter Notes - Chapter 4: Retinal Pigment Epithelium, Visual Acuity, Vitreous Body
Document Summary
1/3 brain devoted to processing visual information. When visual info is in conflict with info from other senses, we bias visual information. We see with our brain eye: instrument to collect, focus and sense light stimulus. John blind at age 30 by occipital lobe stroke. John can navigate his way through the cluttered hallway in the new house of his friend and side step a toy truck. Eye: detects the light stimulus, takes care of the initial stages of processing, and sends the result to the brain for further processing. Light travels as a wave and can vary in two respects: Wavelength: distance between the peaks of successive waves. Variations in amplitude affect the perception of brightness. The greater the amplitude of light wave, the more light is being reflected or emitted by that object, and so that object appears brighter or more intense to us. Greater amplitude more light reflected by object object appears brighter.
