Document Summary

Sensation: stimulation of sensory receptor cells that relay this info to the brain for processing. Perception: result of the neural processing that organize and interpret sensations as representing a certain object of an event.

Psychophysics: the study of the relationship between physical events and the corresponding experience (response) of those events. Sensory transduction: process of converting a specific form of stimuli into neural impulses. Sensory receptor cells: specialized cells that convert some specific stimuli into neural impulses. Light (photons: absolute threshold: minimum amount of a stimulus that is necessary for a person to notice it. 50% of the time, smallest amount of stimulus that one can detect. Smell, taste, touch, hearing, sight: just-noticeable difference (jnd): smallest difference in amount of the stimulation that a specific sense can detect.
