The Eyes Never Lie: Detecting Simulated Traumatic Brain Injury With Eye-Tracking, Robert John Kanser

Wayne State University Dissertations

Performance validity test (PVT) inaccuracies can be explained by both test and extra-test (e.g., research design components) factors. Eye-tracking is a promising technology to enhance assessment of performance validity. Prior research has established that ocular behaviors are reliable biomarkers of (un)conscious cognitive processes. Experimental research on deception has shown that ocular behaviors reliably distinguish feigned concealment of information from honest responding. The primary objective of this study was to examine the incremental utility of incorporating eye-tracking into a clinical PVT to distinguish adults with verified TBI from adults coached to feign cognitive impairment. A secondary objective was to determine the …
