Stanley Weiss's Presentations

Differential Reinforcement and the Stimulus Control of Behavior

Presented at the 2015 Art and Science of Animal Training Conference.

A primary objective of psychology is the prediction of behavior.  Operationally, that means what an individual will do in a particular situation can be anticipated.  When this is possible, we have identified, and understand,  the conditions  influencing the individual’s behavior.  The fact that the behaviors of those we interact with seldom surprise us is an indication that they are behaving as expected and therefore under stimulus control.  Imagine what our world would be like if they weren’t.  This presentation will discuss how stimulus control is acquired.  It will progress from simple biologically predisposed reflexive actions to behaviors that are the product of the differential consequences of one’s behavior in different situations.  A simple example:  One learns that they should use different language and manners when speaking to a teacher than to a fellow student. An understanding of stimulus control phenomena and its related processes can help you better understand your own behavior as well as the behavior of other animals.
