What Is Reinforcement?

Reinforcement is the foundational principle of ABA therapy. It refers to any consequence that follows a behavior and increases the likelihood of that behavior occurring again. When a child uses words to request a toy and immediately receives it, the successful communication is reinforced. When a child completes a task and receives praise, task completion is reinforced. Reinforcement is not bribery; it is the natural mechanism through which all organisms learn.

Positive vs. Negative Reinforcement

Positive reinforcement involves adding something desirable after a behavior (giving praise, a preferred toy, or a treat). Negative reinforcement involves removing something aversive (ending a difficult task when the child requests a break appropriately). Both increase the target behavior. Modern ABA emphasizes positive reinforcement as the primary tool. Negative reinforcement is used strategically, such as teaching a child to ask for a break instead of engaging in problem behavior to escape demands.

Types of Reinforcers

Reinforcers fall into several categories. Primary (unconditioned) reinforcers include food, water, and sensory input that are naturally rewarding. Secondary (conditioned) reinforcers include tokens, stickers, praise, and access to activities that have been paired with primary reinforcers. Social reinforcers like praise, high-fives, and attention are particularly important because they are available in all environments. The most effective reinforcers are identified through preference assessments specific to each child.

Token Economies

Token economies are structured reinforcement systems where children earn tokens (stars, points, checkmarks) for demonstrating target behaviors and exchange accumulated tokens for preferred rewards. Token systems teach delayed gratification, build motivation for less-preferred activities, and bridge the gap between immediate and natural reinforcement. They are commonly used in both clinic and home settings and can be customized to each child’s interests and goals.

Fading Reinforcement

The goal of ABA is for behaviors to eventually be maintained by natural reinforcement rather than programmed rewards. Therapists systematically thin reinforcement schedules over time, moving from continuous reinforcement (every response) to intermittent schedules. External rewards are gradually replaced by natural consequences like social interaction, task completion satisfaction, and increased independence.
