Which term refers to a consequence that decreases the likelihood of a behavior reoccurring?

The correct term that refers to a consequence that decreases the likelihood of a behavior reoccurring is punishment. In behavioral psychology, punishment is defined as any stimulus that follows a behavior and reduces the frequency of that behavior in the future. It serves to discourage certain actions by introducing negative consequences, thereby making it less likely for the individual to engage in that behavior again.

In contrast, terms like reinforcer and reward are associated with increasing the likelihood of a behavior reoccurring by providing positive consequences or incentives. An incentive is often seen as a factor that motivates or encourages a specific behavior, typically involving a positive outcome. This highlights the fundamental difference between how punishment operates to reduce behaviors versus how other terms aim to promote them.
