Abstract
This article reviews studies on development during childhood and adolescence published between July 2012 and June 2013 in Japan. These studies were published in the Japanese Journal of Educational Psychology, the Japanese Journal of Psychology, the Japanese Journal of Developmental Psychology, and the Proceedings of the 55th Annual Meeting of the Japanese Association of Educational Psychology. These studies are classified into six categories : cognitive development, social cognition, interpersonal relationships, self, mental health and adjustment, and the rest. In each category, various studies are reviewed, on such topics as information processing, understanding the concept of lying, peer groups, identity, resilience, and educational studies. In the general discussion section of this article, problems of method and future research directions building on these studies are discussed. The author suggests that developmental studies should emphasize social contributions and interdisciplinary studies.
