Document Summary
Chapter 7 stimulus control: discrimination and generalization. Operant behavior is strengthened when it is followed by a reinforcing consequence; it is weakened when the reinforcing consequence no longer follows the behavior (extinction) Antecedents are stimulus events that precede an operant response the antecedents of a behavior are the stimuli, events, situations, or circumstances that are present when it occurs or were present immediately before the behavior. Stimulus control occurs when a behavior is more likely to occur when a specific antecedent stimulus was present. The antecedent stimulus that is present when a behavior is reinforced is known as the discriminative stimulus (sd) The process of reinforcing a behavior only when a specific antecedent stimulus (sd) is present is called stimulus discrimination training. Two steps are involved in stimulus discrimination training: when the sd is present, the behavior is reinforced, when any other antecedent stimuli except the sd are present, the behavior is not reinforced.
