Document Summary
Sensation: process of detecting external events w/ sense organs & turning those stimuli into neural signals (e. g. sound = air particles pushing against eardrum) Transduction: when specialised receptors transform physical energy of outside world into neural impulses. Perception: involves attending to, organising & interpreting stimuli that we sense (e. g. organise di vibrations of eardrum -> recognise as human voice) Internal representation of world (sense; stimuli; type of receptor) Vision; light waves; light-sensitive structures @ back of eye. Hearing; sounds waves; hair cells that respond to pressure ch in ear. Touch; pressure, stretching, warming, cooling or piercing of skin surface; diff types of nerve endings that respond to pressure, temp ch & pain. Taste; chemicals on tongue & in mouth; cells lining taste buds of tongue. Smell; chemicals contacting mucus-lined membranes of nose; nerve endings that respond selectively to diff compounds.
