Document Summary
The detection of environmental stimuli, such as sounds, objects and smells. The organization, identification and interpretation of that sensation in order to form a mental picture. Synesthesia: perceptual experience of one sense that is evoked by another one: 1. Reception-- the stimulation of sensory receptor cells by energy (sound, light, heat, etc. : 2. Transduction-- transforming this cell stimulation into neural impulses: 3. Rate how bright the light is, how loud the tone is, how large or small: matching: adjust one of two stimuli so they look or sound the same. Turn down volume of one source to match the other. Adjust the colour so they match: detection: detect small differences between stimuli. Measuring sensitivity (for example, just noticeable difference: adjustment: adjust the intensity of the light until you judge it to be just barely detectable. The smallest difference between two stimuli that people perceive 50% of the time.
