Abstract
The purpose of the current study was to investigate which cognitive functions and
personalities were related with the occurrence of the inattentive following in right-turn
driving in intersections. Ten subjects drove the fixed routes in downtown city more
than 35 times. Inattentive following was defined as the followings in the HQL driving
database: 1) the number of visual safety confirmation decreased and 2) the speed at
the maximum steering angle increased with a precedent right-turning car, compared to
without it. These types of inattentive following are unsafe driving, and could lead to
accidents. Subjects also participated in cognitive function experiment (Operation-span
working memory) and answered personality questionnaires (independent – interdepen
dent construal of the self, emotional empathy，impulsiveness etc.). Results indicated
that subjects with low operation-span working memory, high interdependent construal,
high impulsiveness, and high emotional empathy showed the trend of the inattentive
followings in right turn driving situations.
