Document Summary

Important points: stimulus detection, visual system, auditory systems, other sensory systems, gestalt rules, depth. Perception, subliminal perception: you should get an idea of how the systems work rather than the minute details of the components. In some ways, sensation and perception blend together in a way making them difficult to separate but psychologists do distinguish them: sensation: stimulus detection process. Sharks sense electrical currents leaking through fish skins hiding in undersea crevices. If it weren"t for tiny involuntary eye movements that keep images from moving about the retina, stationary objects would fade from sight if we stared: r. m. Photoreceptors: the rods and cones: the retina is a multilayered screen that lines the back surface of the eyeball and contains specialized sensory neurons; is an extension of the brain. If nerve responses are triggered at each of the 3 levels (rode/cone, bipolar cells, ganglion cells), the message is instantly on its way to the visual relay station in the thalamus.
