Vestibular input (VI) activities are linked with skill learning, engagement, and communication. This study investigated the influence of VI activities on the responses of non-verbal children with autism spectrum disorders (CWASD) when prompted to request a reinforcer using picture exchange communication. A single subject alternating treatment…

The Picture Exchange Communication System (PECS) has been widely used to teach functional requesting and commenting skills to children with autism spectrum disorder. Some researchers also modified the PECS to explore its effect on children with other disabilities. The main purpose of this study was to add tangible symbols to PECS (PECS-TS) in…

In the current investigation, we reviewed the literature on mand training for individuals with intellectual and developmental disabilities (IDD) in schools. Ninety-three studies met our inclusion criteria including 225 individual participants. Data were extracted related to participant demographics (e.g., age, disability, response form) and study…

The purpose of this study was to examine the effects of special educators' delivery of training that included an initial training session and follow-up coaching on paraprofessional implementation of an evidence-based practice for students with autism spectrum disorder (ASD). Three special educators each trained a paraprofessional in their…

The purposes of the study were to assess the effects of an online learning module on the implementation of mand training by a classroom team and determine whether training improved manding for a student with multiple disabilities.
