Children who are diagnosed with autism are described as being “on the spectrum,” sitting along the range of neurological impairments, from mild to severe, that compose autism spectrum disorders, or ASDs, but it could be said those so diagnosed are not the only ones on an autism spectrum.In the politically-tinted scientific world, there is what might be called a spectrum of causality, a sweep of beliefs about autism yielding two opposing viewpoints – those who believe the globe is engulfed in an autism pandemic constituting a major public health crisis, and those scientists who say it is all a myth. Put UW-Madison Dr. Morton Anne Gernsbacher in the latter group.
