Background: Bilingual assessment is particularly difficult in the very first period of children's second language (L2) exposure. This exploratory, longitudinal study examined L2 learning after 1 and 2 years of L2 exposure by young immigrants and how it is affected by their age at first exposure to the L2 (AoE). Method: Participants were 18…

We investigate the mechanisms by which a student's age relative to classmates (i.e., relative age) influences risky health behaviors among European adolescents. Using a two-stage least squares approach, we show that relatively young students are more prone to engage in risky behaviors. These results hold after controlling for absolute age, country…

The intention of this article is to contribute to the debate about whether the voting age should be lowered to the age of 16, by examining quantitative and qualitative data collected in a local participation project with young people in Portugal: questionnaires (N = 961), interviews (N = 3), and focus group discussions (N = 15). Considering the…

Emotion dysregulation is common among individuals with autism spectrum disorder (ASD). This study examined the relationship between emotion dysregulation and resting heart rate variability (HRV), a marker of the autonomic nervous system, in ASD adolescents. Resting HRV data were collected from ASD (n = 23) and typically developing (TD) adolescents…

Early identification and intervention are recognised as important elements of the clinical pathway for autism spectrum disorder (ASD). Children with ASD and attention deficit hyperactivity disorder (ADHD) may be diagnosed at a different age than children who only have one of these diagnoses. This systematic review aimed to identify the age at…

Much research has been conducted "on" young people as a population rather than "with" them. Traditionally, porn research has focused on effects--on the assumption that people, especially young people, are impacted by the sexual media they consume, which leads to negative outcomes such as violence and addiction. In this sense,…

The current study investigated the age of diagnosis (AoD) of autism spectrum disorder (ASD) in Nepal by using de-identified data on 246 children with a diagnosis of ASD registered at AutismCare Nepal Society from 2010 to 2015. The mean AoD in children was 58 months (range 14-187 months). Majority of children were male (76%), lived in the Kathmandu…

Introduction: The study aims to investigate the perceived paternal attitudes of children aged between 9 and 17 years in relation to some variables such as child's gender, child's age, the number of siblings, father's working status, and father's level of education. Methods: The study used a survey design. The sample group consisted of 424 children…

The Cognitive Emotion Regulation Questionnaire (CERQ) is a multidimensional measure widely used to access nine cognitive emotion regulation strategies. In this study, we examined the psychometric properties of the CERQ-Short Portuguese version. A sample of 1052 adolescents (aged 10-25 years old, 60.53% females) completed the CERQ-Short form, the…

The presence of cyberspace in the lives of young people is such that we can no longer distinguish between online and offline spheres. They live a process of onlife development that is not always equitable in terms of gender. This paper aims to account for the online behaviour of Spanish adolescents according to gender and age, the decisions they…

This paper evaluates the influence of the classmates' age on individual academic achievement. The identification strategy explores a mechanism for the division of classes based on age homogeneity, with cutoff value determined by the Brazilian law of age at school entry. Fuzzy regression discontinuity estimates a local average treatment effect of…

The rate of child marriage worldwide reaches 21%. Indonesia was the 37th country with the second-highest percentage of child marriages in ASEAN. Adolescent knowledge and attitudes affect behavior in child marriages. Therefore, educational media is needed to increase knowledge and form positive attitudes in adolescents related to the maturation of…

Children develop their language capacities and executive functions (EF) throughout their school-aged years. Research has shown that bilingual children show different patterns of EF performance when compared to their monolingual counterparts. However, it is less clear how variations in children's multilingual experiences associate with variation in…

This study examined the within- and between-day variability of time-segmented sedentary behavior (SB), light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA) in adolescents. The sample comprised 154 adolescents (11-16 years old) from two public schools in Florianópolis, Brazil. The proportion of time spent in SB, LPA, and…

Identity is a foundational element in a person's development and can influence all aspects of a person's life. Although research on adolescent identity development is a growing field, there are opportunities for additional research on this stage of development, with specific focus needed on the role of asynchronous development. This study utilized…
