A Choice Analysis of Food Stealing Consequences in Children With Autism

The team watched autistic children choose between two plates of snacks. One plate sat alone. The other plate had an adult nearby who would scold or block taking food.

Kids went first to the free plate. If they took food there, nothing happened. If they tried the adult plate, the adult stepped in. The researchers counted how often each child stole food under each rule.

Almost every child, 94%, grabbed food when no adult was watching. Only eight of the 17 kids stopped stealing once the adult spoke up.

The big clue: social consequences barely mattered. Most kids kept eating because the taste, smell, and feel of the food felt good all by itself.

McCarron et al. (2002) ran a similar test with finger sucking. Parents watched at home. They also saw the behavior keep going without any social payoff. Both studies show that body-focused or food-focused actions can run on pure sensory fuel.

Goodwin et al. (2012) worked with the same population, autistic children, but looked at asking instead of taking. They learned that kids ask more when they have not had free access to the item. McCord et al. (2025) adds the flip side: when food is free and tasty, many kids will just take it, social rules or not.

Wilkinson et al. (1998) proved that human choice tracks overall payoff. McCord’s team now shows that for autistic children, the immediate sensory payoff often outweighs any later social cost.

Before you write “attention” or “tangible” on the FBA form, run a quick choice check. Put the snack out of reach, then in reach, then with a brief block. If the child still grabs when no one is looking, you have automatic reinforcement. Build your plan around competing sensory items, not time-out or reprimands.
