Further evaluation of contingency modeling to increase consumption of nutritive foods in children with autism and food selectivity
Model eating the food, reinforce bites, and keep the spoon in place only if needed—this three-step chain expands food choices for autistic kids with severe selectivity.
01Research in Context
What this study did
Flanagan and team worked with three autistic children who ate only a few foods.
They used contingency modeling: the adult ate the target food first, then praised and gave a toy when the child took a bite.
If the child still refused after several tries, they added nonremoval of the spoon until one bite was taken.
What they found
All three kids started eating the new foods.
Two children moved forward with just modeling and rewards.
The third child needed the spoon prompt before any food crossed his lips.
How this fits with other research
Demchuk et al. (2026) got the same pattern: most kids responded to simple pairing and shaping, but one needed the spoon prompt.
Peterson et al. (2016) showed that an ABA package beat the SOS sensory method; Flanagan’s modeling tactic is a leaner slice of that same ABA toolbox.
Taylor et al. (2024) later added caregiver check-ins while using the spoon prompt, proving you can keep the procedure parent-friendly.
Why it matters
You now have a quick hierarchy: model, reinforce, then hold the spoon. Start sessions with enthusiastic bites of the target food, deliver big praise and a favorite toy for acceptance, and reserve the gentle spoon prompt for stalls. This sequence keeps treatment light while still having a plan B ready.

03Original abstract
AbstractResearch suggests contingency modeling with differential reinforcement of alternative behavior can increase consumption of nonpreferred foods in some children with feeding problems. The current study further evaluated the effectiveness of this treatment with three children with food selectivity and autism. Participants first observed a positive reinforcement contingency in which the confederate model accessed preferred items and edibles contingent on consuming all of the target foods on their plate. If the participant imitated the model and consumed all of their food, they too received access to the same preferred items and edibles. When this contingency was ineffective for two participants, the confederate and feeder modeled nonremoval of the spoon, which increased consumption for both participants. We conclude with a discussion of potential underlying mechanisms for the effects and future research.
