Study of Decision-Making Fatigue Using Computerized Tests After Mild to Moderate Traumatic Brain Injury

What this Trial Is About

Researchers are investigating decision-making fatigue after mild to moderate traumatic brain injury TBI using two computerized tasks COGED and Restless Bandit. This study aims to measure the effects of TBI during the acute and subacute recovery phases. Both tasks are noninvasive and designed to assess cognitive effort and decision-making behavior in TBI patients and healthy controls. Participants will complete three visits where they perform the COGED task, which includes working memory challenges through the N-back test and a valuation phase measuring perceived cognitive effort. They will also complete the Restless Bandit task, involving choices among targets with changing reward probabilities, while eye tracking records their focus. These computerized assessments help evaluate mental fatigue related to decision-making. During each visit, participants will complete surveys and computer-based tests. Researchers will analyze effort discounting curves from the COGED task and behavioral patterns from the Restless Bandit task to understand decision-making fatigue. The study will track feasibility and acceptability of these assessments over four years, with participants completing all scheduled visits and consenting to the procedures.
