Using a Prerequisite Skills Assessment to Identify Effective Communication Modalities for Mand Training

Many children with Autism Spectrum Disorder (ASD) need support to learn how to communicate their wants and needs. This study examined three different ways to teach children to request preferred items or activities: using sign language, exchanging pictures, and speaking. We compared how three children learned each communication method to determine whether their existing skills influenced which method was most effective. No clear relationship was found between children's existing abilities and how well they learned each communication method. These findings suggest that selecting the most effective communication approach may require considering each child's individual strengths and learning history rather than relying on a single method for all learners.
