What the researchers found was that parents did not accurately perceive the level of their kids’ suffering. Instead, parents based their ratings of Autism “severity” on how much their kids’ behavior bothered them and required a lot of their time and attention. Many children described by parents as “high functioning” were quietly coping with debilitating sensory pain, or were falling behind academically or socially in significant ways. This carries over to how Autistic adults are perceived, and the expectations that neurotypical institutions place on us to appear “normal.”
