Peggy has been working nights and weekends to get a project completed at work. She is successful, and a couple of weeks later she comes into work and her boss presents her with a bonus check. This BEST illustrates the value of reinforcement.

The correct answer is letter "B": positive reinforcement.

Explanation:

American psychologist B.F. Skinner (1904-1990) proposed the Operant Conditioning theory to describe the process by which individuals learn influenced by rewards and punishments. The theory establishes a direct relationship between behavior and the consequences of that behavior.

Skinner described positive reinforcement to the fact of providing a reward to an individual after a given behavior. The individual is likely to repeat the same behavior with the expectation of receiving the reward constantly. In such a way the reward represents the reinforcement stimulus.

Thus, the bonus check Peggy's boss gave her is a stimulus given to motivate her to continue working hard.
