Stimulus (psychology)
In psychology, a stimulus is an energy change (such as light or sound) which is registered by the senses. In behaviorism and related stimulus–response theories, a stimulus constitutes the basis for behavior, whereas it constitutes the basis for perception in perceptual psychology. In this context, a distinction is made between the distal stimulus (the external, perceived object) and the proximal stimulus (the stimulation of sensory organs).
