Study Arms:
- Control subjects (Type: None): Control subjects = 237. These subjects underwent extensive testing with computerized neuropsychological tests including digit span testing, spatial span testing, simple reaction time testing, choice reaction time testing, finger tapping, verbal fluency, design fluency, verbal list learning, questionnaire completion, and the trail making test.
- TBI patients (Type: None): TBI patients N = 28. These patients underwent extensive testing with computerized neuropsychological tests including digit span testing, spatial span testing, simple reaction time testing, choice reaction time testing, finger tapping, verbal fluency, design fluency, verbal list learning, questionnaire completion, and the trail making test.
