Outline of Final Research Achievements

Two longitudinal twin studies, for childhood and adulthood, were conducted.
In the children cohort, about 200 pairs of fifth graders(11yrs) answered the questionnaire asking academic abilities, social adaptability and educational environments. 120 pairs were given individual develpmental survey for executive functions and so on. Genetic and environmental stability and changes were found in those traits and rythmic tempo showed an interesting GxE interaction.
In the adulthood cohort, about 200 pairs of twins answerd the questionnaire asking social attainment, mental health and so on. Resting state of brain for IQ discrepant monozygotic twin paris (8 pairs) were investigated by fMRI and relationship between brain network in left Inferior Temporal Gyrus and IQ was found. It was also suggested that genetic contribution of prosocial behavior differed according to social situation.
