Loneliness is prevalent in adolescents. Although it can be a normative experience, children and adolescents who experience loneliness are often at risk for anxiety, depression, and suicide. Research efforts have been made to identify the neurobiological basis of such distressful feelings in our social brain. In adolescents, the social brain is still undergoing significant development, which may contribute to their increased and differential sensitivity to the social environment. Many behavioral studies have shown the significance of attachment security and social skills in adolescents' interactions with the social world. In this review, we propose a developmental social neuroscience model that extends from the social neuroscience model of loneliness. In particular, we argue that the social brain and social skills are both important for the development of adolescents' perceived loneliness and that adolescents' familial attachment sets the baseline for neurobiological development. By reviewing the related behavioral and neuroimaging literature, we propose a developmental social neuroscience model to explain the heightened perception of loneliness in adolescents using social skills and attachment style as neurobiological moderators. We encourage future researchers to investigate adolescents' perceived social connectedness from the developmental neuroscience perspective.

This report is part of a larger project investigating school satisfaction of early adolescents in Hong Kong. The research questions in this part of the study focused on the school experience of 21 high-ability Chinese students aged 9–14 in Hong Kong primary and secondary schools. Semi-structured interviews were conducted with each of the participants. From the qualitative data collected, six influences on their school satisfaction emerged ― two that could be classified as ‘personal influences’ (goal-directed thoughts and motivation; self-discipline and self-regulation) and four themes that reflected ‘environmental influences’ (positive teacher-student relationships, classmates emotional and instrumental support, parental involvement in students’ learning, talent development opportunities). The findings from the study can help to inform school personnel on modifiable aspects of school environments that can help high-ability students succeed and at the same time enjoy their school life.
