Recall readiness in children with autism

When people are asked to learn information they need to judge when they have encoded the information accurately and will be able to retrieve it correctly. Making such a judgment is an aspect of metacognitive ability, and is referred to as "recall readiness." Previous researchers have not considered recall readiness in children with autism, therefore we asked matched groups of children with autism, children with mental retardation, and normally developing children (mean mental age: 7 years) to study several pictures of objects until they felt ready to recall all the objects without error. Their recall was then tested. The children with autism and the children with mental retardation had impaired recall readiness compared to the normally developing children. We discuss this result with reference to other research into the metacognitive abilities of children with autism.
