Summary

Extinction and positive reinforcement increased untrained toy play in children. When previously reinforced actions were stopped, new ways of playing with toys emerged.

Area of Science:

  • Behavioral Psychology
  • Child Development
  • Applied Behavior Analysis

Background:

  • Children with developmental disabilities often exhibit restricted play repertoires.
  • Understanding how to expand play skills is crucial for cognitive and social development.

Purpose of the Study:

  • To investigate the impact of extinction and positive reinforcement on the emergence of novel toy play topographies in children.
  • To determine if withholding reinforcement for established play behaviors could induce untrained play topographies.

Main Methods:

  • A baseline assessment of toy play was conducted.
  • Children were individually trained on specific toy play topographies.
  • Previously reinforced topographies were then placed on extinction.

Main Results:

  • Baseline play was characterized by a lack of appropriate toy engagement.
  • Training on specific topographies led to initial skill acquisition.
  • Extinction of previously reinforced topographies resulted in the induction of untrained topographies.

Conclusions:

  • Extinction procedures can be effective in increasing the variety of play behaviors.
  • Positive reinforcement combined with extinction offers a viable strategy for expanding children's play repertoires.
  • This approach has implications for therapeutic interventions aimed at enhancing children's play skills.
