The architecture of sleep undergoes distinct changes during childhood and early adolescence. Slow wave sleep is involved in memory processing and may support active consolidation of newly encoded representations to support the formation of abstracted "gist" memories. Here, we examined sleep and overnight memory formation in German school…

Autobiographical remembering develops in childhood. A late-developing cognitive tool is the cultural life script. The present study aimed at exploring the beginnings of its acquisition and at replicating its acquisition in early adolescence in a Southern-European culture. Study 1 established the Portuguese normative adult cultural life script,…

Divergent cultural, religious, and ideological beliefs and practices are often challenging to contemplate and difficult to accept when they conflict with an individual's own convictions and way of life. The recognition that children and adolescents grow up in an increasingly diverse world has led to a general interest in fostering tolerance. In…

The brain undergoes profound development across childhood and adolescence, including continuous changes in brain morphology, connectivity, and functioning that are, in part, dependent on one's experiences. These neurobiological changes are accompanied by significant changes in children's and adolescents' cognitive learning. By drawing from studies…

Although peer relations are recognized as a fundamental developmental context, they have been rarely studied as a means of understanding the effects of socioeconomic status and inequality. In this paper, we show how and why peer relations provide a unique and powerful opportunity to assess the differential risks and resources available in the peer…

Poor mental health in childhood and adolescence has a significant impact on both physical and mental health throughout life. However, growing evidence suggests that current levels of child and adolescent mental health (CAMH) care are insufficient to meet the needs of many children and adolescents in the United States as evidenced by increasing…

Body neutrality is a concept wherein individuals embody a neutral attitude toward the body that is realistic and flexible, appreciate and care for the function of the body, and acknowledge that self-worth is not defined by one's outward appearance. Family behavior regarding body image has been related to higher levels of body dissatisfaction and…

The aim of this study was to examine the developmental trajectories of comprehension of relational concepts among 557 participants with intellectual disability (ID) of undifferentiated etiology (M age = 12.20 years, SD = 3.18) and 557 typically developing (TD) participants (M age = 4.57 years, SD = 0.80). Logistic regression analyses, with…

This paper explores the external developmental assets and how they manifest in specific youth programs from Colombia, Guatemala, and Honduras. An evaluation process was created through a qualitative phenomenological with the youth programs' leadership. To triangulate the data, a survey was developed and piloted with a small sample from three youth…

Studying development processes, as they unfold over time, involves collecting repeated measures from individuals and modeling the changes over time. One methodological challenge in this type of longitudinal data is separating retest effects, due to the repeated assessments, from developmental processes such as maturation or age. In this article,…

There is limited research on the trajectory of restricted and repetitive behaviors (RRBs) in fragile X syndrome (FXS), with previous studies only examining males and/or examining RRBs as a unitary construct rather than delineating subtypes of RRBs. Thus, we described the trajectory of five subtypes of RRBs in 153 males and females with FXS (aged…

The overall aim of this grounded theory multiple-case study was to better understand how K-12 independent schools ("schools") in the United States cultivate a connection between children and adolescents ("students") and the natural world ("environment") by exploring the interplay between this connection and (a) the…

Despite increased popular and research interest in youth development and outdoor education, very little research has focused upon the design principles that enhance the effectiveness of these programs. This article presents a scoping review of the literature discussing youth development activities occurring in outdoor environments, in order to…

The psychological impacts of war on young learners' social and emotional development are examined in this integrated review. Not only can war and armed conflict have a profound influence on individual children, but they also negatively affect the entire family system. The difficulties associated with relocation, migration, and acclimatisation to…

Emotion regulation abilities play a crucial role in child and adolescent development. Thus, there is a need to investigate correlates and predictors of the emotion regulation abilities in adolescents. Previous studies have shown that attachment security plays an important role in the development of adaptive emotion regulation strategies; however,…
