Abstract
Metacognition is one of the cognitive processes included under the general term executive functions. The executive functions are widely held to be under the control of the prefrontal cortex, an area often damaged after severe traumatic brain injury (TBI). We examined the metacognitive processing of a group of 9 children with TBI, and a group of 9 healthy, age-matched control children. Children with TBI showed significant impairments in their accuracy of prediction of the ease with which an item would be learned and their ability to predict recall of an item after a 2-hr delay. No significant differences in recall performance between the TBI and control groups were exhibited. The results are interpreted as suggesting an impairment in metacognitive processing resulting from frontal lobe damage after TBI in children. Additional research is necessary to confirm the relation of frontal lobe pathology and severity of injury to metacognitive impairments.
