Document Summary
4. 1 - sensation and perception at a glance. The process of detecting external events by sense organs and turning those events into neural signals. At the sensory level, the sound of someone"s voice is simply noise and the sight of a person is a combination of colour and motion. Involves attending to, organizing, and interpreting stimuli that we sense. Perception includes recognizing the sounds as a human voice and understanding that the colours, shape, and motion together make up the image of a human being. Is the process in which physical/chemical stimulation is converted into a nerve impulse that is relayed to the brain. The transduction of sound takes place in a specialized structure called the cochlea, where what we hear is converted into messages that travel to hearing centers of the brain. Is the reduction of activity in sensory receptors with repeated exposure to stimulus.
