Document Summary

Module 4. 1 sensation and perception at a glance. Sensation and perception are different, yet integrated processes. Sensation the process of detecting external events by sense organs and turning those stimuli into neural signals. At this level, sound is just noise, and the sight of a person is merely a combo of color and motion this info is sent to the brain where perception occurs. Perception involve attending to, organizing and interpreting stimuli that we sense. Includes recognizing the sounds as a human voice and understanding that certain colors, shapes and motion together make up the image of a human being walking toward you. Transduction when specialized receptors transform the physical energy of the outside world into neural impulses. These impulses travel into the brain and influence the activity of different brain structures, which gives rise to our internal representation of the world. Sensory receptors involved in transduction are different for different senses.
