Auditory script location does not affect acquisition and maintenance of vocal initiations by children with autism

Increasing Verbal Interaction in Children with Autism Spectrum Disorders Using Audio Script Procedure

This study aimed at investigating the effectiveness of audio script and script-fading procedure in teaching initiation to children with ASD. Three children with ASD and a parent of each child participated in the study. A nonconcurrent multiple baseline design across children was used. The findings showed that the initiation emitted by the children increased during audio script and script-fading procedure. Children also generalized initiation across different conditions and maintained the acquired skills. Finally, the social validity findings showed that the opinions of the parents regarding the procedure were overall positive. Results were discussed in terms of recommendations for practitioners and future research.

Establishing a Generalized Repertoire of Initiating Bids for Joint Attention in Children with Autism

The current study evaluated whether multiple-exemplar training, auditory scripts, and script-fading procedures could establish a generalized repertoire of initiating bids for joint attention in four young children with autism. Stimuli drawn from each of three experimenter-defined categories were used during teaching to program for generalization of initiations of bids for joint attention from trained stimuli to novel stimuli. A fourth category was reserved for assessment of across-category generalization of bids for joint attention. The four categories were (a) visually enticing toys, (b) unusually placed items, (c) environmental sounds, and (d) pictures. Assignment of categories for teaching and assessment of generalization was counterbalanced across the participants. Three different auditory scripts were used during intervention for each of the training stimuli to program for response generalization. All four children learned to initiate bids for joint attention. After scripts were subsequently faded and reinforcement was thinned, bids for joint attention were maintained and also generalized to novel stimuli and settings.
