Abstract
[Purpose] Eye movements during single- and dual-task walking were compared. [Subjects and Methods] Fourteen healthy young participants walked with (single-) and without (dual-task walking) calculation to measure the angles of combined movements of both their eyes using an eye movement measurement system. [Results] On comparing single- and dual-task walking, the angles of combined movements of both eyes were significantly greater in the former. [Conclusion] Eye movements were promoted during dual-task walking, reflecting increased attention needed for calculation. The results suggest that attention to the frontal eye field is reduced when walking while calculating.
