Answer:
When Aaron's teacher began responding to his habit of kicking other children with an immediate time-out, the frequency of this misbehavior steadily declined. The time-out best illustrates as the punishment.
Step-by-step explanation:
In behavior analysis time out is considered as the negative punishment or the removal punishment as it separates the person from the environment which is reinforcing him/her to show certain behavior. As in the above mentioned case Aaron has the habit of kicking other children so the teacher gave him a time out punishment by removing him from the class.
