Which example illustrates negative reinforcement?

The correct example of negative reinforcement is where a teacher removes homework for good behavior. Negative reinforcement occurs when a behavior is strengthened by the removal of an aversive stimulus. In this case, the aversive stimulus is the homework, which is removed as a reward for exhibiting good behavior. This encourages the child to repeat the good behavior in the future to avoid homework.

When thinking about negative reinforcement, it's essential to understand that it is not about punishment but rather about increasing a desirable behavior by eliminating something unpleasant. In the context of this scenario, the removal of an unpleasant task (homework) serves to reinforce and likely increase the occurrence of the good behavior.

Other examples may involve different mechanics of behavior modification, but the key here is that effective negative reinforcement relies on the relief or removal of an unpleasant condition, which positively influences the likelihood of a desired behavior reoccurring.
