Influence on concentration and work efficiency by wearing of Hachimaki

Abstract

Japanese people often wear a Hachimaki on our heads in order to increase their concentration and work efficiency. In this paper, we investigate whether wearing a Hachimaki can improve concentration and the amount of work per unit time. We focus on a change in the performance in two types of tasks with or without a Hachimaki. The first task is Uchida-Kraepelin test. The purpose of this experiment is to determine whether wearing a Hachimaki has a relation to concentration. The second task is a pegboard test. The purpose of this experiment is to examine whether wearing a Hachimaki influences the amount of fingertip work. As a result, we could not find a significant difference by t-tests in the Uchida-Kraepelin test and a pegboard test with or without a Hachimaki. This result suggests that wearing a Hachimaki does not change concentration and work efficiency.
