Document Summary
Sensation: the reception of physical stimulation and encoding of it into the nervous system. Perception: the process of interpreting and understanding sensory information, the act of sensing then interpreting that information. Cones: 7 million color sensitive- red, green and blue: fovea (the highly sensitive region of the retina responsible for precise, focus vision): where most of the cones lie in, some cones have private bipolar cells iii. Inattentional blindness: failure to see an object we are looking directly because our attention is directed elsewhere. Tachistoscope (t-scope): an apparatus designed to present visual stimuli in a controlled position for a short period of time (ms) nowadays, computer instead control preexposure and postexposure fields. 3x4 array of letters in 50 ms blank postexposure field report remembered display. Pattern recognition: written language visual sensory memory here is to encode the visual information into the memory system.
