Using audio script fading and multiple-exemplar training to increase vocal interactions in children with autism

Area of Science:

• Developmental Psychology
• Applied Behavior Analysis
• Autism Spectrum Disorder Research

Background:

• Script-fading procedures are effective for teaching social interactions to children with autism.
• Previous research lacked demonstration of generalized vocal interactions controlled by natural stimuli.

Purpose of the Study:

• To teach children with autism to initiate conversations using script-fading.
• To generalize vocal interactions across novel toys and settings.

Main Methods:

• A script-fading procedure was used with 4 boys with autism.
• Training involved multiple categories and exemplars of toys.
• A multiple-probe design across participants assessed the intervention's effects.

Main Results:

• The intervention successfully elicited vocal interactions from children with autism.
• Interactions were brought under the control of relevant environmental stimuli (toys).
• Generalization of vocal interactions across novel toys was demonstrated.

Conclusions:

• Script-fading is an effective method for teaching generalized vocal interactions in children with autism.
• The study highlights the importance of training with diverse stimuli for generalization.
• Further research should explore specific implementation variables like fading techniques and participant characteristics.
