Acquiring Answering Skills to WH-Questions in a Child with Intellectual Disability and Autism Spectrum Disorder;

The aim of this study was to investigate the effectiveness of intervention when it comes to facilitating the acquisition of interrogative response skills in a child with intellectual disability and autism spectrum disorder who was in the sixth grade of a prefectural special needs school.The four interrogatives targeted included "who," "what," "what is it doing," and "where."The intervention was divided into four stages: a stage to confirm that the participant understood the persons, objects, actions and places used in the practice (preliminary intervention); a stage to teach the participant to distinguish between the elements of the photo cards of persons, objects, actions, and places (Stage I); a stage to teach the participant to respond to interrogatives using the photo cards (Stage II); and a stage to teach the participant to respond to interrogatives using videos (Stage III).At the beginning of the intervention, the correct response rate for interrogatives was around 30% to 50%, but eventually rose to approximately 90%, and the intervention produced certain results.The effectiveness of the gradual intervention and using videos was discussed in relation to the results of the intervention.
