Which of the following is an example of negative reinforcement?

Negative reinforcement involves a process where a behavior is strengthened by the removal of an aversive stimulus. In this context, the example of removing chores when a child behaves well aligns perfectly with the principle of negative reinforcement. By eliminating the chores, which could be seen as an unpleasant task or a burden, it increases the likelihood that the child will continue to exhibit the desired behavior in the future. Here, the removal of chores serves as the reinforcing factor that encourages the child to behave well again, showcasing an application of negative reinforcement in behavior modification.

Other choices involve different types of reinforcement or rewards that are not related to the removal of an aversive condition, thus not fitting the definition of negative reinforcement.
