Final answer:
Behaviorism is the subdiscipline in psychology that believes consequences shape behavior and that elements in our environment change our behavior. B.F. Skinner was the leader of this field.
Step-by-step explanation:
The subdiscipline in psychology which believes that consequences shape behavior and that elements in our environment change our behavior is behaviorism.
B.F. Skinner, the leader of this subdiscipline, focused on how behavior was affected by its consequences. He spoke of reinforcement and punishment as major factors in driving behavior. Skinner's research led to the development of the operant conditioning chamber, also known as a Skinner box, which is used by researchers to study behavior.
According to Skinner, behavior is motivated by the consequences we receive for our actions. Behaviors that are followed by satisfying consequences are more likely to be repeated, while behaviors followed by unpleasant consequences are less likely to be repeated.
