Summary

Preferred stimuli effectiveness varies with task difficulty. Progressive-ratio schedules and behavioral economics can identify reinforcers for behavior change, especially for high-effort tasks.

Area of Science:

  • Behavioral psychology
  • Applied Behavior Analysis
  • Behavioral economics

Background:

  • Reinforcing stimuli may differ in effectiveness as response requirements increase.
  • Understanding differential reinforcer effectiveness is crucial for behavior modification.

Purpose of the Study:

  • To evaluate responding under increasing schedule requirements using progressive-ratio schedules and behavioral economic analyses.
  • To examine the differential effectiveness of preferred stimuli in treating destructive behavior maintained by automatic reinforcement.

Main Methods:

  • Utilized progressive-ratio schedules to assess response requirements.
  • Employed behavioral economic analyses to quantify reinforcer effectiveness.
  • Investigated the treatment of destructive behavior using differential reinforcement.

Main Results:

  • One of two tested stimuli was consistently associated with higher responding under increasing schedule requirements across participants.
  • Stimuli demonstrating greater effectiveness under high-demand conditions were generally more successful in reducing destructive behavior.
  • A differential effect was observed, with reinforcers showing varied efficacy based on task effort.

Conclusions:

  • Progressive-ratio schedules and behavioral economic analyses offer a promising technology for reinforcer identification.
  • Findings suggest that reinforcers may be equally effective for low-effort tasks but differentially effective for high-effort tasks in clinical settings.
