Document Summary

Information comes through our sense: our brain interprets this information, you look with your eyes, you see with your brain. Stimulus-detection process: organs translate stimuli into nerve impulses, perception, organizing and giving meaning to input. 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 t(cid:396)a(cid:448)els th(cid:396)ough the at(cid:373)osphe(cid:396)e, a(cid:374)d (cid:449)he(cid:374) it is fo(cid:272)used (cid:271)y the eye"s opti(cid:272)al syste(cid:373). The result is the proximal stimulus, the image of the tree on the retina, which is a representation of the tree. Receptor processes (step 3: the process, sensory receptors are cells specialized to respond to environmental energy, ex. Rods and cones: visual pigment are specialized cells that reacts to light, transduction occurs, which changes environmental energy to nerve impulses. Specialized receptors change the light energy into nerve impulses. Figure: step 3 of the perceptual process.
