Involves organizing and translating sensory input into something meaningful such as your best friend"s face or other environmental stimuli. Psychophysics: the study of how physical stimuli are translated into psychological experience. Thresholds: looking for limits: sensation begins with a stimulus, any detectable input from the environment, a threshold is a dividing point between energy levels that do and do not have a detectable effect. An absolute threshold for a specific type of sensory input is the minimum amount of stimulation that an organism can detect.
