Final answer:
Engaging in behavior to obtain rewards or incentives such as money is an example of operant conditioning, where behaviors are motivated by the consequences they bring. The law of effect explains that behaviors followed by satisfying consequences are more likely to be repeated.
Step-by-step explanation:
When we engage in behavior in order to obtain rewards or incentives such as money, it is an example of operant conditioning. Psychologist B.F. Skinner proposed that behavior is motivated by the consequences we receive for the behavior. According to the law of effect, behaviors that are followed by satisfying consequences are more likely to be repeated. So, when we engage in behavior to obtain rewards like money, it is because we have learned that doing so can lead to positive outcomes.
