Document Summary

Sensation: the process of detecting external events by sense organs and turning those stimuli i(cid:374)to (cid:374)eural sig(cid:374)als. At the se(cid:374)sory le(cid:448)el the sou(cid:374)d of so(cid:373)eo(cid:374)e"s (cid:448)oi(cid:272)e is si(cid:373)ply (cid:374)oise, a(cid:374)d the sight of a person is merely a combination of color and motion. All of this raw sensory information is then relayed to brain where perception occurs. Perception: involves attending to, organizing and interpreting stimuli we sense. Perception includes the recognizing the sound as human voices, and understanding colors and shapes and motions together make up the image. The raw sensation detected by the sensory organs are turned into information that the brain can process called transduction. Transduction: when specialized receptors transform the physical energy of the outside into neural impulses. These neural impulses travel into the brain and influence the activity of different brain structures. We hear because auditory information gets sent to our temporal lobes.
