Eye movements in Multiple Object Tracking systematically lagging behind the scene content

Popis výsledku v původním jazyce

In the current experiment I investigated whether the eye movements during Multiple Object Tracking (MOT) are based on the object positions in future or rather in past. Importantly this can be done without assumptions about specific participants? strategies. I recorded eye movements in MOT with 60 trials (N=20). Participants tracked 4 of 8 objects for 10 seconds (speed 5deg/s). For every subject five trials were repeated four times each during the experiment and four times more in reversed direction. Foreach repeating trial I used Normalized Scanpath Saliency measure adapted for dynamic scenes to compare the eye movements between trials presented in forward and backward direction. I varied the latency between -250 ms (prediction) and +250 ms (lag) andlooked for the local maximum (90 % of comparisons had maxima within the inspected range). The systematical lag was present in each participant (mean 99ms; 95 %CI 81- 116 ms).
