Outline of Final Research Achievements

This study examined whether the season of birth was associated with self-regulation, i.e., effortful control and aggression, in infancy using the Hamamatsu Birth Cohort for Mothers and Children. Compared to those born in winter, infants aged 18 months who born in spring and summer were higher on effortful control and were lower on aggression. The findings suggest that season of birth may predict development of self-regulation in infancy. Further research should focus on the underlying mechanisms of the effects of birth season on development of children's self-regulation.
