Applied behavior analysis Definitions and concepts Differential Reinforcement
 Differential reinforcement is a way that people can learn to make correct responses over time. The correct behavior is reinforced and the incorrect behavior is not reinforced. Over time people will learn to make the correct response because they want to get the reinforcement. A SD signals that reinforcement is available. A S-delta does not tell the person anything about the availability of reinforcement. A S-delta is not likely to produce responses because there is reinforcement is not given.
