Analyzing Consequence Variables Within the High-Probability Instructional Sequence for a Child Diagnosed With CHARGE...

Area of Science:

• Behavioral Psychology
• Developmental Disabilities
• Applied Behavior Analysis

Background:

• Individuals with developmental disabilities often display noncompliance during intensive instruction.
• The high-probability instructional sequence (high-p sequence) is a strategy to improve compliance by presenting high-probability requests before low-probability ones.

Purpose of the Study:

• To compare the effectiveness of different consequences (praise, edibles, videos) for compliance with high-p and low-p instructions.
• To investigate the efficacy of varied reinforcement using preferred music videos for a child with CHARGE syndrome.

Main Methods:

• A single-subject design was used with an 11-year-old girl diagnosed with CHARGE syndrome.
• Treatment analyses compared praise, edibles, and music videos as consequences for compliance.
• Presession preference assessments were conducted to identify preferred music videos for reinforcement.

Main Results:

• Edibles were initially more effective than praise but lacked maintenance.
• Music videos replicated the high-p sequence efficacy but failed to fade demands or maintain behavior.
• Varied reinforcement with preferred music videos resulted in high levels of compliance.

Conclusions:

• The high-p sequence is effective for increasing compliance in individuals with developmental disabilities.
• Varied reinforcement, specifically using preferred music videos identified through preference assessments, is crucial for maintaining compliance.
• Findings highlight the importance of motivating operations in behavioral interventions.
