Driving requires a high level of cognitive capacity, but it tends to decline as older. The data set covered in this study relates to the gaze time measured when a subject 60 years of age or older is actually driving. We studied by correlation and regression analysis the relationship between these data and results of various cognition tests. In result, divided attention is related with the collected data when eyeball is moving at high speed and processing speed is related with these of at low speed. We also examined the possibility that the required cognitive abilities differ depending on speed.
