Behavior Modification • Based on ______techniques (B. F. Skinner, 1947). – – e. g. , – These conditions are called____ – Once cued by an antecedent

Behavior Modification • Consequence of the response. • Scenario 1: A person approaches the elevator and sees the heart smart sign. It is the person’s first time at this elevator, she sees the sign and takes the stairs. Once at the top, she realizes how good that made her feel and she also beat the elevator to the top. Because of this positive reinforcement, she will take the stairs again.

Behavior Modification • Scenario 2: A person approaches the elevator and has seen the signs many times before. The stairway is dirty, cold and empty. In this scenario, there is no reinforcing consequence associated with taking the stairs, but there is a reinforcing consequence take the elevator (safer). It is likely that the antecedent cue of this heart smart sign is not enough to elicit the behavior of taking the stairs in this scenario. •
