Summary

Children with developmental disabilities can overcome food selectivity. Limiting preferred foods and using positive reinforcement helps children consume nonpreferred foods, reducing problem behaviors associated with eating challenges.

Area of Science:

  • Behavioral Psychology
  • Developmental Pediatrics
  • Applied Behavior Analysis

Background:

  • Excessive food selectivity is common in children with developmental disabilities.
  • Problem behaviors often accompany food selectivity, complicating interventions.
  • Understanding controlling variables is crucial for effective treatment.

Purpose of the Study:

  • To identify variables controlling problem behavior during food selectivity.
  • To examine the role of establishing operations in improving food selectivity.
  • To assess the efficacy of a contingency-based intervention with and without prior access to preferred foods.

Main Methods:

  • Functional analyses were conducted to understand behavior.
  • Interventions varied based on access to preferred foods and reinforcement contingencies.

Related Experiment Videos

  • Problem behavior and food consumption were systematically measured.

    • Main Results:

    • Problem behavior was significantly higher when presented with nonpreferred foods.
    • Consumption of nonpreferred foods occurred only when preferred food access was limited and reinforcement was provided.
    • Functional analysis indicated negative reinforcement maintained problem behavior.
    • Establishing operations enhanced the effectiveness of the reinforcement contingency.

    Conclusions:

    • Limiting access to preferred foods can serve as an establishing operation, increasing the effectiveness of reinforcement for consuming nonpreferred foods.
    • Contingency-based interventions, when combined with appropriate establishing operations, can ameliorate food selectivity and associated problem behaviors in children with developmental disabilities.
    • Findings have implications for community-based interventions and inform the comparison of stimulus fading versus escape extinction strategies.
