Document Summary

Sensation and perception at a glance (module 4. 1) Sensing the world around us sensation 132 the process of detecting external events by sense organs and turning those stimuli into neural signals perception 132. Attending to, organizing, and interpreting stimuli that we sense. Ex) recognizing the sounds as a human voice and understanding that certain colours, shapes, and motion together make up the image of a human being walking toward you. A skill that our brains learn through experience transduction 132 specialized receptors transform the physical energy of the outside world (raw sensations from the sensory organs) into neural impulses. These neural impulses travel into the brain and influence the activity of different brain structures, which ultimately gives rise to our internal representation of the world. The brain separates different sensory signals from one another so that we can experience distinct sensations (sight, sound, touch, smell, and taste).
