Answer:
The answer is "reinforcement and punishment"
Step-by-step explanation:
The introduction of a pleasant stimulus is reinforcement, which is its removal. For one thing, there are several different types of stimuli that drive activity toward a specific goal.
It is thought that when a nice stimulus is supplied, the best effect would be achieved, however when a pleasant load is presented, the intended consequence may no longer be necessary, even when an action has already been taken and may have been taken. This acts as a symbol of retribution.
