Document Summary

Sensation - act of using our sensory systems to detect environmental stimuli. Perception - conscious recognition and identification of a sensory stimulus. Sensory receptor cells - specialized cells that convert a specific form of environmental stimuli into neural impulses. Sensory transduction - process of converting a specific form of environmental stimuli into neural impulses. Absolute threshold - minimal stimulus necessary for detection by an individual. Difference threshold/just noticeable difference - minimal difference between two stimuli necessary for detection of a difference between the two. Sensory adaptation - process whereby repeated stimulation of a sensory cell leads to a reduced response. Bottom-up processing - raw sensory data is sent to the brain and your brain uses all of that data to build a perception. Top-down processing - using previously learned information to help recognize and interpret the data coming into your brain. Perceptual set - readiness to interpret a certain stimulus in a certain way.
