Punishment

Negative reinforcement and punishment serve distinct functions in behavior modification.

Negative reinforcement improves the desired behavior by removing an unpleasant stimulus, like turning off an annoying alarm by getting out of bed.

Conversely, punishment decreases the likelihood of undesired behavior.

Positive punishment involves adding an unpleasant stimulus, like sending a student to the principal's office to stop texting during class.

Negative punishment involves removing a pleasant stimulus, like taking away a child's toy for misbehavior.

Punishment often indicates what not to do but doesn't teach better behavior.

A student punished for mistakes may fear the teacher instead of learning not to commit the same mistake. It may also lead to subversive behavior, like a child avoiding stealing only when parents watch as parents punish the stealing behavior.

Physical punishment can model aggression. For example, spanking a child for misbehavior when angry might lead them to hit friends over toy-sharing disputes.

Reinforcement is often more effective than punishment. For example, praising a child for sharing encourages sharing better than punishing them for not sharing.
