Brief Summary:
Metacognition, in-the-moment awareness of performance while engaging in cognitive tasks, is negatively affected by traumatic brain injury (TBI). Metacognitive deficits can greatly reduce quality of life for individuals with TBI as functioning in this domain has been closely linked with successful independent living and community re-integration. Problematically, there are currently no empirically validated treatment options that address metacognitive deficits after TBI. Recent research in healthy samples demonstrates that specific listening interventions may alter neural activation in brain works associated with metacognition and can improve metacognitive functioning; however, it remains unknown if these effects generalize to individuals with TBI. Thus, the objective of the proposed study is to use a double-blind, placebo controlled randomized clinical trial to determine the efficacy of applying a specific listening intervention to improve metacognition after TBI and to employ functional magnetic resonance imaging (fMRI) to document the neural mechanisms by which the intervention operates.

Primary Outcome Measures :
  1. Goodman and Kruskal gamma coefficient on MRI-based metacognitive task [ Time Frame: 7 weeks ]
    While participants are in the scanner, they will perform a metamemory paradigm that involves the completion of 2 components per trial: 1) a memory task (a non-verbal recognition task), and 2) a metacognitive task that immediately follows completion of every recognition item. Accuracy of metacognitive functioning can be quantified using the Goodman and Kruskal gamma coefficient,16 a value between -1 and 1, indicating the discrepancy between the participant's judgment and objective performance that is commonly used in the metacognitive literature.
