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…

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…

We study the links between family configuration and formation on the one hand and adult literacy skills on the other by analysing data from the Programme for the International Assessment of Adult Competencies (PIAAC), a survey of 250,000 people aged 16 to 65 conducted by the OECD in 33 countries and economies. Literacy proficiency has an effect on…

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…

This article presents three studies, two of them longitudinal, which investigated the relations between age, processing speed, working memory (WM), and fluid intelligence ("g[subscript f]") from 4 to 16 years of age. Structural equation modeling showed that speed was a powerful covariate of age ([approximately] - 0.6 to - 0.7) from 4 to 13 years,…

This study examines the influence of players' age, gender, and gaming preferences and habits (from now on, "gaming preferences") on the effectiveness of a specific videogame that has been designed to increase the interest towards classical theater among teenagers. Using a validated instrument, participants were divided into four groups…

Prior studies have demonstrated that events causing displacement from parents--such as parental death, abandonment of the adolescent, or divorce--represent a risk factor for adolescent suicide, but research to date has not established a theoretical model explaining the association between parental displacement and adolescent suicidal behavior. The…

Identification of the causes of child maltreatment perpetration is prerequisite for developing efficacious prevention initiatives to reduce its occurrence. Earlier maltreatment victimization is often suggested as an important cause of subsequent maltreatment perpetration. This study investigates a) whether maltreatment victimization causes…

Enjoyment of physical activity (EPA) is positively correlated with activity, yet little is known of its relationship with enjoyment of physical education (EPE). This study's purpose was to explore EPE and its relationship to EPA. Cross-sectional data (N = 4122, average age 14.5 plus or minus 1.7 years, 48% male) were collected as part of the CSPPA…

Previous studies with adults have shown that age has an important influence on laypeople's wisdom theories. However, children's and adolescents' understanding of the concept of wisdom has hardly been investigated. In the current study, 80 children and adolescents completed a questionnaire concerning an event where they had been wise and an event…

The current study examined whether important distinctions are masked if participant age is ignored when modeling relationships among constructs associated with the work-family interface. An initial omnibus model of social support, work role stressors, and work-family conflict was tested. Multiple groups analyses were then conducted to investigate…

Despite being ignored, visual distractors often produce traceable negative priming (NP) effects that can be used to investigate inhibitory processes. Robust NP effects are typically found with young adults, but not with children. Using 2 different NP tasks, the authors compared NP in 5 different age groups spanning 5 to 25 years of age. The 1st…

Objective: To present estimates of the lifetime prevalence of "DSM-IV" mental disorders with and without severe impairment, their comorbidity across broad classes of disorder, and their sociodemographic correlates. Method: The National Comorbidity Survey-Adolescent Supplement NCS-A is a nationally representative face-to-face survey of…

The present study examined discrimination attributions in the psychological well-being of Black adolescents. Findings are based on a representative sample of 810 African American and 360 Caribbean Black youth, aged 13-17, who participated in the National Survey of American Life. Youth completed measures of perceived discrimination, discrimination…

Methods: The study used a cross-sectional experimental design. Post-primary schools in the Eastern Health Board Area of Northern…
