Using multiple-tact training to produce emergent visual categorization in children with autism

Area of Science:

• Behavioral science
• Developmental psychology
• Autism spectrum disorder research

Background:

• Children typically learn object names before category names.
• Previous studies suggest a link between naming, tacting, and categorization in children with autism spectrum disorder (ASD).

Purpose of the Study:

• To replicate previous findings on categorization and naming in children with ASD.
• To investigate if multiple-tact training can establish visual categorization and listener behavior in children with ASD.

Main Methods:

• A nonconcurrent multiple baseline design was employed across two children with ASD.
• Multiple-tact training was used to teach common names for stimuli.
• Visual categorization was assessed using a picture sorting test.
• Listener behavior was evaluated in relation to the learned names.

Main Results:

• Both participants successfully categorized visual stimuli based on common names after training.
• Participants demonstrated corresponding listener behavior, indicating understanding of the category names.
• The results support the effectiveness of multiple-tact training for establishing categorization.

Conclusions:

• Multiple-tact training is an effective method for teaching visual categorization and listener behavior in children with ASD.
• This approach may help bridge the gap between learning specific object names and understanding broader categories.
• Findings have implications for educational and therapeutic interventions for children with ASD.
