Summary
To boost requesting in individuals with intellectual disabilities, presenting incomplete activities or objects as rewards proved effective. This method more than doubled requesting rates for most participants, offering a practical approach.
Area of Science:
- Behavioral Psychology
- Developmental Disabilities
- Applied Behavior Analysis
Background:
- Establishing and increasing manual signed and spoken requesting is crucial for individuals with intellectual disabilities.
- Previous methods include the blockable response conditioned establishing operation (BR-CEO) and interrupted chain procedures.
Observation:
- This study investigated a novel approach using incomplete versus complete referents as consequences for requesting.
- Six individuals with severe/profound intellectual disabilities participated in a reversal design study.
Findings:
- Presenting incomplete referents significantly increased requesting rates in five out of six participants.
- Requesting rates more than doubled for the majority of individuals studied.
Implications:
- Incomplete referent presentation is a potentially practical and effective strategy to enhance communication in individuals with intellectual disabilities.
- This finding contributes to the development of more effective intervention strategies for this population.
