Evaluating Three Methods of Stimulus Rotation when Teaching Receptive Labels

Area of Science:

• Developmental Psychology
• Applied Behavior Analysis
• Autism Spectrum Disorder (ASD) Intervention

Background:

• Receptive label training (auditory-visual conditional discriminations) is a key component of early intervention for autism spectrum disorder (ASD).
• Discrete trial teaching (DTT) is a widely used method for teaching these skills.
• The role of stimulus arrangement (counterbalancing) in DTT is debated, with concerns about preventing unintended stimulus control.

Purpose of the Study:

• To evaluate the effectiveness of three distinct stimulus rotation strategies for teaching receptive labels.
• To compare counterbalanced, fixed, and clinician's choice methods in early intervention for young children with ASD.

Main Methods:

• An adapted alternating treatment design was employed across three stimulus sets and five young participants diagnosed with ASD.
• The study assessed three stimulus rotation approaches: counterbalanced, fixed, and clinician's choice.
• Maintenance and generalization of learned receptive labels were also evaluated for all conditions.

Main Results:

• All three stimulus rotation methods (counterbalanced, fixed, clinician's choice) proved effective in teaching receptive labels.
• The effectiveness was consistent across participants and stimulus sets.
• Maintenance and generalization data were collected for targets taught under each rotation condition.

Conclusions:

• The findings suggest flexibility in stimulus rotation methods can be effective for teaching receptive labels in early ASD intervention.
• This supports the use of various practical approaches within Discrete Trial Teaching (DTT).
• Implications for current early intervention practices are discussed, highlighting the efficacy of different stimulus rotation strategies.
