[Purpose] This study examined the visual and cognitive factors affecting Multiple Object Tracking (MOT) skills using visual search strategies. Cognitive functions of selective attention and information processing speed were studied. [Subjects] Participants were 25 male college students with 19.44 years as average age. [Methods] The Neuro Tracker MOT task was used to measure the participants’ MOT skills. We used glasses measuring Ocular Motor Skills to simultaneously measure visual search activity during the task. Ocular Motor Skills data included the gaze travel distance, the number of stops, the stop time, and the stationary point’s travel speed. For visual function measurement, we adopted eight standard Japanese items (Static Visual Acuity, Kinetic Visual Acuity, Dynamic Visual Acuity, Contrast Sensitivity, Ocular Motor Skills, Depth Perception, Visual Reaction Time, and Eye/Hand Coordination). For cognitive function measurement, we used the Stroop/Reverse-Stroop Test-II. [Results] MOT skills were designated as the dependent variable, Ocular Motor Skill data (4 items), visual function (8 items), and cognitive function (2 items) were designated as the independent variables. Multiple regression analyses were performed for all the independent variables. No significant differences were found for any item with Ocular Motor Skill data and cognitive function as independent variables. However, among visual functions, a significant difference was observed in the Visual Reaction Time. [Conclusion] The results suggest that improving the visual functions to acquire information instantaneously (0.1 sec) may improve MOT skills. This study is useful for research on the expansion of conventional training methods and determinants of MOT skills.
