In the context of examination as for the relation between handedness and brain function, many studies have investigated cognitive function of the left-handed people using behavioral measures such as the Stroop test, however the relation still remains unclear. In this study, the relation between handedness and executive function was examined using the Stroop test performances of 100 left-handed (50 males and 50 females) and 100 age-matched right-handed (50 males and 50 females) healthy community dwellers. They were from the database of the Yokumo Study. The mean age of the participants was 61.7 (SD = 10.8). The results of the present study did not show any significant difference either in the color naming speed or the Stroop interference effect size. Possible contribution of aging effects of hemisphere lateralization on cognitive function in upper middle aged left-handedness was discussed.
