Autism severity may stem from fear

Most people know when to be afraid and when it’s ok to calm down.

But new research on autism shows that children with the diagnosis struggle to let go of old, outdated fears. Even more significantly, the Brigham Young University study found that this rigid fearfulness is linked to the severity of classic symptoms of autism, such as repeated movements and resistance to change.

For parents and others who work with children diagnosed with autism, the new research highlights the need to help children make emotional transitions – particularly when dealing with their fears.

“People with autism likely don’t experience or understand their world in the same way we do,” said Mikle South, a psychology professor at BYU and lead author of the study. “Since they can’t change the rules in their brain, and often don’t know what to expect from their environment, we need to help them plan ahead for what to expect.”

The complete study appears in the journal Autism Research.
