Twenty-one participants (11 females) were subjected to a cognitive test before and after being exposed to a stereoscopic 3D environment. They were categorized into two groups, fatigued and unfatigued, based on their response times and subjective data. The fatigued group exhibited significantly reduced P600 amplitudes and delayed P600 latencies in the post-viewing condition compared to those in the pre-viewing condition. Significant fatigue effects for the fatigued group were also observed at P-4 and O-2 sites during the 8.57 Hz attended task; attend/ignore ratios in this cortical hemisphere after 3D viewing were smaller than those before 3D viewing.
