Final answer:
Brianna giving her son a ten-dollar bill for completing his homework is an example of positive reinforcement, which aims to increase the likelihood of the behavior being repeated by introducing a desirable stimulus. The answer is option A.
Step-by-step explanation:
When Brianna gives her son Pauly a ten-dollar bill for doing all his homework, this is an example of positive reinforcement. Positive reinforcement is a concept in operant conditioning where adding a desirable stimulus strengthens the likelihood of the behavior being repeated. In this scenario, the money serves as the reinforcing stimulus, increasing the likelihood of Pauly completing his homework in the future.
Consequently, positive reinforcement not only encourages the continuation of a specific action but also plays a critical role in behavior modification, particularly in educational settings where students may be incentivized for academic achievements. B.F. Skinner, a renowned psychologist who heavily contributed to the field of behaviorism, highlighted the effectiveness of positive reinforcement, and his principles continue to influence modern approaches to teaching and parenting.
