If you are a professional who is interested in showing these video clips in an upcoming presentation or training session, you may do so by linking your computer directly to the ASD Video Glossary on the Internet when you train or present. Alternatively, you can order a copy of the DVD, On the Spectrum: Children and Autism, a 24-minute educational video that shows side-by-side clips of typical and atypical development. Some of these clips are used in the ASD Video Glossary. For ordering information, click here.


Welcome to the ASD Video Glossary, an innovative web-based tool designed to help parents and professionals learn more about the early red flags and diagnostic features of autism spectrum disorders (ASD).

This glossary contains over a hundred video clips and is available to you free of charge. Whether you are a parent, family member, friend, physician, clinician, childcare provider, or educator, it can help you see the subtle differences between typical and delayed development in young children and spot the early red flags for ASD. All of the children featured in the ASD Video Glossary as having red flags for ASD are, in fact, diagnosed with ASD.

Please keep in mind that there are many presenting features associated with ASD that are depicted in the video clips you are about to see. However, most children do not show all of the features all of the time. Instead, many children have some of the features some of the time. Awareness of these common presenting features may help to heighten your index of suspicion. Individually, they may not indicate a problem; however, in combination, they may indicate a need to conduct a screening or a diagnostic evaluation. Not all signs and features need be present for ASD to be diagnosed. Please note: the ASD Video Glossary is not a diagnostic tool.
