In this study, international and national assistant referees (ARs) were tested on offside decision-making accuracy and accuracy of memory. Eye movements were tracked during the observation of video clips and frozen frames. The international ARs clearly performed better than the national ARs for response accuracy on the video clips, but not for the frame recognition. Interestingly, for the incorrect responses, the international ARs chose more frames behind the offside line, and the national ARs more frames ahead. The eye movement data only revealed a significant longer observation length on the frames for the international ARs. These observations lead us to believe that international ARs used a strategy of compensation for the forward displacement of the attacker induced by the flash-lag effect. Future research should focus on the awareness of the perceptual illusion and the compensation strategy of the ARs.
