Document Summary
4. 1 sensation and perception at a glance. Process of detecting and translating the complexity of world into meaningful experiences occurs in. Sensation: process of detecting external events by sense organs and turning these stimuli into neural signals. Raw sensory info is then relayed to brain. Perception: attending to, organizing, and interpreting stimuli that we sense. Includes recognizing the sounds, and understanding certain colours, motions, and shapes make up images. Transduction: specialized receptors turn physical energy of outside world into neural impulses. Neural impulses travel into brain and influence the activity of diff. brain structures, giving rise to our internal representation of the world. Sensory receptors involved are different for the different senses. Transduction of light occurs when it reaches receptors at back of the eye. Light sensitive chemicals in retina convert energy into nerve impulses which travel to various parts of the brain where colour, motion and objects are perceived.
