Answer:
Punishment
Explanation:
B.F. Skinner was known for his work on Operant Conditioning.
Operant conditioning is a form of learning where behavior is strengthened when followed by reinforcement and weakened if followed by punishment.
Punishment could be positive or negative, where an aversive stimulus is introduced (for example, spanking a naughty child) or a desirable stimulus is withdrawn (for example, less TV time).
The end result of punishment is to decrease the likelihood of a behavior occurring again.
