Final answer:
Behaviorist B.F. Skinner would most likely describe Brody's response to earning an A in a course, where his parents give him $20 each time, as a positive reinforcement.
Step-by-step explanation:
Behaviorist B.F. Skinner would most likely describe Brody's response to earning an A in a course, where his parents give him $20 each time, as a positive reinforcement.
According to Skinner, behaviors that are followed by consequences that are satisfying to the organism are more likely to be repeated. In this case, receiving an A in the course and getting $20 from his parents are the positive consequences that reinforce Brody's behavior of earning good grades.
By providing Brody with a monetary reward for his achievement, his parents are using positive reinforcement to increase the likelihood that he will continue to earn A's in the future.
