This article reviews studies on psychological development during adolescence and beyond. The target studies are journal articles published in Japan from July 2018 to June 2019, and poster presentations delivered at The 61st Annual Meeting of the Japanese Association of Educational Psychology. In the review, studies on adolescence are classified from the viewpoint of the stage of schools and main topics, and their contents are summarized. As a result, it is revealed that many of the studies delivered at the meeting were biased towards research about college students. Additionally, these studies also contained issues related to sampling methods, sample size, and the generalization of their research findings. As an alternative, it is suggested that the background, context, and characteristics of the participants and location of their colleges be carefully described.
