The development of executive function (EF) has been linked to various life outcomes, motivating intense research on the topic. While much of this research has focused on more thoroughly understanding age-related changes of the underlying neurocognitive mechanisms involved, recent theoretical and empirical works have stressed how the immediate…

Social gaming--online gameplay involving digital interactions with others--is a common form of social media use among adolescents. Research on this topic has neglected the social aspect of gaming and the potential role of social gaming in adolescent development. In this article, we define social gaming, drawing on interdisciplinary theories to…

Loneliness becomes more prevalent as youth transition from childhood into adolescence. A key underlying process may be the puberty-related increase in biological stress reactivity, which can alter social behavior and elicit conflict or social withdrawal (fight-or-flight behaviors) in some youth, but increase prosocial (tend-and-befriend) responses…

Forming and maintaining friendships is one of the most important developmental tasks in adolescence. Supportive and high-quality friendships have been related to positive developmental outcomes and mental health, both concurrently and in the long term. Friendships also protect against negative effects of adverse experiences, such as peer…

Many young people are inclined toward risk taking and also toward helping other people. "Prosocial risk taking" is a term that can describe different ways that youth provide significant instrumental and emotional support to family members, friends, and strangers, even when it involves a personal risk. In this article, we review research…

Recent genetic discoveries offer a new lens through which to study cognitive, emotional, behavioral, and social processes that are foundational to children's development. In this article, we review the latest advances in genomics--genome-wide association studies and the polygenic scores that have come out of them--and discuss how these techniques…

How does language shape mathematical development? In this article, we consider this question by reviewing findings from cross-sectional and longitudinal research. In this literature, we find that differences in the structures of languages and individual variations in language ability are associated with mathematical performance in both obvious and…
