Abstract

Eye movements reflect neurocognitive and psychophysiological processes linked to attention, cognitive load, and emotional arousal, making them relevant for forensic investigations. This study examined the integration of eye-tracking with Virtual Reality (VR) crime scene exposure. Forty participants (20 experimental, 20 control) were exposed to a VR mock crime scene and assessed using the Eye Detect Polygraph. The experimental group showed significantly greater fixation duration, gaze activity, pupil dilation, and AOI engagement for crime-related stimuli (p<.05). Eye Detect results largely classified experimental participants as deceptive and controls as credible or inconclusive, supporting VR-based eye tracking and ocular credibility assessment as a potential preliminary screening tool in forensic psychological investigations.
