Summary
Functional Communication Training (FCT) and noncontingent reinforcement (NCR) equally reduced self-injurious behavior (SIB). However, FCT promoted more consistent increases in alternative behaviors, suggesting a distinct benefit beyond reinforcement control.
Area of Science:
- Behavioral Psychology
- Applied Behavior Analysis
- Developmental Disabilities
Background:
- Functional Communication Training (FCT) is a treatment for behavior disorders.
- Its effectiveness is often linked to an individual's perceived control over reinforcement delivery.
Observation:
- This study investigated the role of reinforcement control in FCT effectiveness.
- Three adults with mental retardation exhibiting self-injurious behavior (SIB) participated.
- A multielement design compared FCT to Noncontingent Reinforcement (NCR).
Findings:
- Both FCT and NCR were equally effective in reducing SIB.
- Control over reinforcement delivery did not appear to influence behavioral suppression.
- FCT resulted in more consistent increases in the alternative response compared to NCR.
Implications:
- The findings suggest that perceived control may not be the primary mechanism for SIB reduction via FCT.
- FCT may offer unique benefits in promoting adaptive communication skills.
- Further research can explore the specific mechanisms driving alternative response increases in FCT.
