Differentiate punishment and extinction with respect to behavior change mechanisms.

Differentiate punishment and extinction with respect to behavior change mechanisms.

• A. Punishment introduces a consequence to reduce behavior; extinction removes reinforcement for the behavior, leading to a decrease over time; both reduce behavior, but extinction does not introduce new aversive stimuli whereas punishment does.
• B. Punishment and extinction are identical; both remove all consequences.
• C. Punishment decreases behavior by withholding reinforcement; extinction decreases behavior by adding aversive stimuli.
• D. Punishment relies on extinction; extinction relies on punishment.

Answer: (A)

Punishment and extinction differ in how they change behavior. Punishment reduces behavior by introducing a consequence after the behavior, to make it less likely to occur in the future. This can be adding something aversive (positive punishment) or removing something desirable (negative punishment). Extinction reduces behavior by withholding the reinforcement that previously followed the behavior, so the behavior is no longer strengthened and tends to decrease over time. Importantly, extinction does not introduce new aversive stimuli; it simply blocks the reinforcement that was maintaining the behavior. You may see an extinction burst at first, but the mechanism is changing contingencies rather than adding a new consequence.
