Concepts

Reinforcement

A consequence is reinforcing when the behavior it follows becomes more likely.

Definition

Reinforcement is a process in which an action’s consequence increases the future probability or frequency of that action in relevant conditions.

How to understand it

Positive reinforcement adds something after an action; negative reinforcement removes or prevents something aversive. Both increase the action. Positive and negative describe the direction of an environmental change, not its moral value. The behavior must be named before the consequence can be classified accurately.

A promised reward is not automatically a reinforcer. If the intended action does not increase, calling the outcome reinforcement outruns the evidence. This functional definition directs attention to what happened over repeated opportunities rather than to what the person arranging the consequence hoped would happen.

Ending the reminder tone

Teaching scenario

A fictional study-room device emits a repetitive reminder until a participant stores shared headphones in their case. Across sessions, prompt storage increases. Ending the tone could be negative reinforcement of storage because something is removed and the behavior increases. In a separate arrangement, adding a preferred activity after storage might positively reinforce it. The example classifies relationships; it does not recommend using irritating devices or assume the same result for every participant.

Constructed for learning. This scenario is not a report of an empirical finding or a diagnosis.

Common confusion: Punishment

Reinforcement increases behavior; punishment decreases it. Removing something can serve either process, depending on what changes next.

Compare reinforcement and punishment

Limits of the concept

  • The same consequence may reinforce one person’s behavior without reinforcing another’s.
  • An outcome can reinforce an unintended action if that is what it consistently follows.
