Sibling bullying is highly prevalent and has been found to have adverse effects on mental health lasting into early adulthood. What is unknown is what predicts sibling bullying roles (uninvolved, victim, bully-victim and bully). This study aimed to identify precursors of sibling bullying roles in middle childhood using a large sample of 6,838…

Introduction: In the "new ecology of learning" it is becoming crucial to trace the paths of learning experiences that students develop both in school and outside it. Few research studies have focused on out-of-school activities. In this paper, we explore differences between children and adolescents in their participation through 26…

The Ministry of Education, Culture, Sports, Science and Technology in Japan (2011) started the 'Foreign Language Activities' in fifth grade based on the new Courses of Study in April of 2011. The ministry has considered beginning this course in third grade and the 'English Course' in 5th grade in order to improve students' reading, writing,…

Autism spectrum disorders (ASD) are characterized by early onset qualitative impairments in reciprocal social development. However, whether individuals with ASD exhibit impaired recognition of facial expressions corresponding to basic emotions is debatable. To investigate subtle deficits in facial emotion recognition, we asked 14 children…

Substantial individual differences exist in regard to type and amount of experience with variable speech resulting from foreign or regional accents. Whereas prior experience helps with processing familiar accents, research on how experience with accented speech affects processing of unfamiliar accents is inconclusive, ranging from perceptual…

Many interventions are characterized by repeated observations on the same individuals (e.g., baseline, mid-intervention, two to three post-intervention observations), which offer the opportunity to consider differences in how individuals vary over time. Effective interventions may not be limited to changing means, but instead may also include…

This study explored the profiles of Longitudinal Life Environmental Satisfaction (LLES) during the COVID-19 pandemic, evaluating their predicting role in social-emotional adjustment in children and early adolescents. 488 children (M[subscript age] = 8.54; SD = 0.63), and 129 early adolescents (M[subscript]age = 11.08, SD = 0.48) completed two…

The present study examined individual differences in theory of mind (ToM) among a group of 60 children (7-11 years-old) with autism spectrum disorder (ASD) and average intelligence. Using open-ended and structured tasks to measure affective ToM, cognitive ToM, and spontaneous social attribution, we explored the nature of ToM and assessed whether…

The Short Sensory Profile (SSP) is one of the most commonly used measures of sensory features in children with autism spectrum disorder (ASD), but psychometric studies in this population are limited. Using confirmatory factor analysis, we evaluated the structural validity of the SSP subscales in ASD children. Confirmatory factor models exhibited…

Both genes and the environment are important for individual differences in expertise, but little is known about gene-environment interactions underlying domain-specific achievement. Here we explored this issue in a large Swedish twin cohort (N = 6,610), using moderator modeling with musical expertise as a model domain. Specifically, we tested…

This article outlines research in which six primary teachers were interviewed and asked to discuss their ability to identify giftedness in a range of domains. Teachers seemed more likely to identify giftedness in domains in which they perceived themselves to have a higher level of content knowledge. This small-scale study suggests that variations…

Scholars in the field of conflict resolution in schools theoretically argued that minor distractions and disturbances are conflicts. In the present study, we refer to them as emerging conflicts. The study has been carried out within the phenomenographic research tradition and used semi-structured interviews. We addressed the professionals -- the…

There is considerable variability in the extent to which young people with developmental language disorder (DLD) experience mental health difficulties. What drives these individual differences remains unclear. In the current article, data from the Twin Early Development Study were used to investigate the genetic and environmental influences on…

The aim of the current article is to extend prior conceptualizing by presenting a model of social and emotional competence that recognizes both the mechanisms and the manifestations of social and emotional competence. The Social and Emotional Competence School Model draws together conceptual underpinnings from the social and emotional competence…

An association between attachment and academic performance appears to be consistently found in children; however, reports on such an association in adolescents are contradictory. This study aimed to determine whether the attachment dimensions of anxiety or avoidance significantly correlate with a student's academic performance at university.…
