Document Summary

Information comes in through our senses: organs translate stimuli into nerve impulses, organizing & giving meaning to input, our brains interpret this information, you look with your eyes - you see with your brain. The perceptual process: the major events that occur between the time a person looks at the stimulus in the environment (the tree in this example) and a the tree, recognizes it and takes action towards it. Step 1: information about the tree (the distal stimulus) is carried by light. Step 2: the light is transformed when it is reflected from the tree, when it travels through the at(cid:373)osphere, a(cid:374)d (cid:449)he(cid:374) it is fo(cid:272)used (cid:271)(cid:455) the e(cid:455)e"s opti(cid:272)al s(cid:455)ste(cid:373). Receptor processes (step 3: the process, sensory receptors are cells specialized to respond to environmental energy, visual pigment are specialized cells that react to light, transduction occurs, which changes environmental energy to nerve impulses. Specialized receptors change the light energy into nerve impulses.
