Intertrial and interobserver variability of eye movements in Multiple Object Tracking

Popis výsledku v původním jazyce

Do we repeat our eye movements when we track the same multiple moving dots again? We analysed eye movements of twelve observers during 10-s multiple object tracking task (MOT). The experiment included 64 trials in 4 blocks, half of the trials were repeating trials presented once in each block. To estimate the similarity of eye-movements across conditions we used normalized scanpath saliency measure (NSS), similar to the recent NSS application in dynamic natural scenes. We compared the NSS scores using ANOVA with factors Subject (Same/Different) and Trial (Same/Different). Same Trial Same Subject condition means comparing a trial with its repetition in different blocks. We found both effects significant. The highest eye movement consistency was in samesubject watching the repeated trial condition, followed by the case when different subjects observe the same trial. The results show that there is a similarity of eye movements within the same MOT task.
