Document Summary

Sensation: the detection of environmental stimuli, such as sounds, objects and smells. Reception: the stimulation of sensory receptor cells by energy (sound, light, Transduction: transforming this cell stimulation into neural impulses. When many sensors in the body convert to physical signals from the environment into encoded signals sent to the cns. You can enjoy ice cream even if you don"t that it"s the process of transduction. Transmission: delivering this neural information to the brain to be processed. Perception: the organization, identification and interpretation of that sensation in order to form a mental picture. Synesthesia: perceptual experience of one"s senses that is evoked by another scent. Psychophysicists: often measure the minimum amount of a stimulus needed for detection. Psychophysics: methods that measure the strength of a stimulus and the observer"s sensitivity to that stimulus. Example: rate how bright the light is, how loud the tone is, how large or.
