Virtually all behavior produces a change in the environment that can function as a stimulus. Any movement that an organism makes results in a change in the visual stimulation affecting another organism that is observing the situation. Many actions also result in the production of other stimuli. Appropriate movements of the vocal musculature result in auditory stimuli. Behavior that results in contact with another organism may result in tactile stimuli which can affect the other organism. Behavior may result in permanent or relatively permanent stimuli, as do the arm movements required for writing when they leave visible marks on a piece of paper.
A stimulus with the following features:
It is the result of someone’s behavior
Formal or dynamic characteristics of the stimulus (e.g., mode or intensity)
Formal or dynamic characteristics of the response that produces it
The function of the stimulus (e.g., discriminative, reinforcing)
