Final answer:
Nonexclusion time-out is a form of negative punishment where a child is removed from an activity to decrease misbehavior, without being completely isolated from the environment.
Step-by-step explanation:
Nonexclusion time-out occurs when a child is temporarily removed from an engaging activity as a form of negative punishment, but not completely isolated from the environment where the activity is taking place. Instead of being sent to a different location, the child might be required to sit on the sidelines, still in view of the activity they were participating in before the misbehavior. This strategy is aimed at decreasing unwanted behaviors by limiting access to reinforcing situations without complete exclusion from the social or physical environment.
