The Feeling and Psychophysics
The feeling is the stimulation of sensory organs by a stimulus. Perception is the organization, interpretation, analysis, and integration of stimuli from our sense organs and brain.
Psychophysics studies the relationship between the physical nature of sensory stimuli and the responses they evoke.
Sensory Thresholds and Adaptation
The absolute threshold is the minimum amount of physical intensity needed to detect a stimulus.
