autistic EEG results (long SOA)
Even when the intervals between shifts are relatively long, the autistic brain still doesn't show the normal pattern of modulation of background EEG.

This is significant, because people with autism are able to detect targets at these long intervals.
This abnormality of the EEG even when behaviour is intact suggests that they must be using some compensatory mechanism that works at long intervals but breaks down when attention must be reoriented rapidly.
