Traditionally, children have generally been considered as developmentally immature and unable to experience spirituality. However, more recent studies seem to indicate the opposite.

Academic attainment is a core education policy priority. Wellbeing is recognized as critical for adolescent development, and is linked to academic attainment.

Research shows that peer relationships are associated with students' school adjustment. However, the importance of advantageous and disadvantageous factors for students' educational outcomes may vary by socioeconomic positioning. Drawing on sociometric and register data from a nationally representative sample of Swedish youth (n = 4996, girls 50%;…

The purpose of this study was to address the role of social comparison in determining individual development by exploring the relationship of four types of social comparison with academic persistence-procrastination and subjective well-being among Chinese adolescents (n = 530, M[subscript age] = 14.59) from both variable- and person-centered…

The benefits of afterschool activity participation for youth development are well-documented. An interesting question dominating this field is whether there is a threshold at which point participating in too many activities (breadth) and spending too much time in those activities (intensity) is negatively associated with desirable outcomes. Using…

In this study, we investigate how the accumulation of stressful life events and chronic stressors experienced in adolescence predict young adults' future self-identification (i.e., connectedness, vividness, and valence of the future self) in a sample of 1482 Swiss youth. Furthermore, we investigate future self-identification as a source of…

Cultural background can influence cognition, including executive functions (EFs), abilities that encompass skills responsible for self-regulation of thoughts and behavior. The seminal unity and diversity model of EFs proposes the existence, in adulthood, of at least three correlated but separable EF latent (shared variance in more than one…
