Sensory extinction and sensory reinforcement principles for programming multiple adaptive behavior change.

The team worked with children who had developmental delays. Each child spent long periods in self-stim behavior that gave its own sensory payoff.

The researchers first removed the payoff. They blocked the sound, feel, or sight that the behavior produced. Next they gave toys that gave the same feel or sound. They used an ABAB reversal design to show the change was real.

When the sensory payoff stopped, self-stim dropped sharply. The same sensory feel or sound later made good toy play rise.

The new play kept going even after extra reinforcers were removed. One procedure cut problem behavior and built a new skill at the same time.

Wilkie et al. (1981) conceptually replicated the idea. They showed vibration, music, and strobe lights work as well as food or praise for teaching language.

Osnes et al. (1986) extended the same logic to prevocational work. A teen earned brief object self-stim breaks and his work rate rose while stereotypy fell.

Li et al. (2025) used response-stimulus pairing instead of extinction. They also saw more toy play and less stereotypy in autistic preschoolers. The 1979 sensory-redirection idea holds across ages, tasks, and methods.

You can turn the very thing that fuels self-stim into fuel for learning. First block the payoff to cut the problem behavior. Then pick toys or tasks that give the same sound, feel, or light to build new skills. Start with a quick assessment of what sensory consequence the child seeks. Use simple barriers or mufflers during extinction, and keep the new item close at hand. The same sensory principle works for play, work, and language targets.

Sensory extinction is extinction applied to behavior maintained by automatic reinforcement. Many repetitive or self-stimulatory behaviors are not maintained by attention or escape but by the sensory feedback they produce, such as the sound of an object spinning or the visual and proprioceptive input from a movement. Sensory extinction masks or removes that sensory product so the behavior no longer pays off.

A classic example is placing carpet under a plate a child likes to spin: the spinning still happens, but the auditory feedback is muffled, so the behavior declines. Other arrangements include padding surfaces, using gloves, or blocking a specific sensory channel. The goal is to break the link between the response and its reinforcing sensory consequence.

This differs from the more familiar extinction of socially mediated behavior, where you withhold attention or stop allowing escape. With sensory extinction there is no other person delivering the reinforcer, so the procedure targets the physical sensory outcome instead.

Sensory reinforcement is the automatic sensory stimulation that maintains a behavior, whether auditory, proprioceptive, or visual. Sensory extinction is what happens when you remove that stimulation. The two ideas are two sides of the same relationship: identify the sensory reinforcer, then remove it to test and treat the behavior.

In this study the researchers first identified the sensory consequence maintaining each child's self-stimulation. They systematically removed and reintroduced auditory, proprioceptive, or visual consequences in a reversal design. When removing one specific consequence reduced or eliminated the behavior, that consequence was labeled the child's preferred sensory reinforcer.

Crucially, the same sensory reinforcer that maintained self-stimulation could also be used to build new, appropriate behavior. That link between diagnosis and treatment is what makes the sensory framework so useful.

In the study's second phase, children were offered toys that produced the kind of sensory stimulation they preferred. They played selectively with those matched toys, and the appropriate play was durable even without added external reinforcers or restraints on self-stimulation. The authors called this building play into a natural community of sensory reinforcement.

The practical lesson for behavior analysts is to pair sensory extinction with matched, appropriate alternatives. Removing the sensory payoff of a problem behavior works better when you also provide a socially acceptable activity that delivers the same class of stimulation, so the person has a good way to access the reinforcement they were seeking.
