Metacognition and executive functioning are two higher order cognitive processes that share similarly structured theoretical models, as well as common areas of associated neural networks. Despite the similarities, little research has been done to investigate the potential relationship between these two congruent processes. This current study aims to empirically and objectively examine the relationship between executive functioning and metacognition using a sample of adults with moderate to severe traumatic brain injury. Participants were recruited to complete a neuropsychological battery that included tests of both metacognition and executive functioning that would provide the data necessary to determine the nature of the relationship between the processes. Results suggest that the participants in the traumatic brain injury sample performed as well as healthy individuals on tasks of metacognition, and that performance on executive functioning tasks that involve a problem solving component were associated with metacognitive ability.
