The REAL difference between AUTISM and Language Delays

As a psychologist I get asked the question, ... ..."How do you really know the difference between AUTISM and language delays?" ... ..."How do you know it's AUTISM and not deficits in social skills because they are stuck at home due to COVID and not seeing any other kids?" ... ..."How do you know it's AUTISM and not strong-willed, normal three year old behavior??" In this video I share the behaviors that professionals look for in their assessments for characteristics of AUTISM and how that differs from pure language delays and other copy-cat behaviors.
