This paper reviews developmental studies on children in infancy, early, and middle childhood. The target studies are journal articles published in The Japanese Journal of Educational Psychology, The Japanese Journal of Developmental Psychology, The Japanese Journal of Psychology, and The Japanese Psychological Research from July 2019 to June 2020. This review also addresses trends in poster presentations delivered at The 62nd Annual Meeting of the Japanese Association of Educational Psychology. Due to the large number of studies on children's social involvement, the journal articles are classified into three categories — involvement with parents, with teachers, and with people around the children — and then reviewed. The findings from the articles are highlighted and future directions are discussed.
