Error-correction problems in autism: evidence for a monitoring impairment?

Abstract

With a task involving the launching of missiles at targets, Malenka et al. (1982) and C. Frith and Done (1989) showed that schizophrenic patients with delusions of alien control and auditory hallucinations were likely to leave erroneous responses uncorrected whose outcomes were not visible until the missile hit or failed to hit the target, while being able to correct visible errors adequately. This is consistent with an impairment in the central monitoring of action. Using a similar task, we found that children with autism were more likely than controls to fail to correct both kinds of error. Data are interpreted in terms of difficulties with constructing visual schemata for actions.
