AP PSYCHOLOGY

Detailed explanation-1: -Skinner used the term reinforcer to refer to any event that strengthens or increases the likelihood of a behaviour, and the term punisher to refer to any event that weakens or decreases the likelihood of a behaviour.

Detailed explanation-2: -Pleasant consequences are reinforcers; they strengthen the behavior and make it more likely to occur in the future. Unpleasant consequences are punishers; they reduce the likelihood that the behavior will be repeated.

Detailed explanation-3: -A reinforcer is any consequence that causes the preceding behavior to increase. The increase may be in intensity, frequency, magnitude or some other quality.

Detailed explanation-4: -A Punisher is any aversive stimulus that is used as a consequence to an action for the purpose of decreasing or extinguishing repeated occurrences of that action. In other words, it’s what makes up a punishment.
