Studying within-person variability in children's behavior is frequently hindered by challenges collecting repeated observations. This study used wearable accelerometers to collect an intensive time series (2.7 million observations) of young children's movement at school (N = 62, M[subscript age] = 4.5 years, 54% male, 74% Non-Hispanic White) in…

Symptoms of inattention (IA), hyperactivity, and impulsivity present in school-aged children are important indications of developmental problems. The assessment of these symptoms largely relies on questionnaires completed by parents, teachers, and the children themselves. However, inherent perceptual biases may lead to inaccuracies in these…

We used latent profile analysis to identify major behavioral self-regulation profiles among children who were assessed as developmentally vulnerable in terms of hyperactivity and inattention. We examined three domains of behavioral regulation: (a) cognitive--behavioral regulation by way of learning behaviors; (b) social-behavioral regulation by…

Objective: To examine the manifestation of cognitive control deficit of children with different levels of hyperactivity, an "at risk" dimension for ADHD. Method: A group of children with high hyperactivity (N = 40) and another group of children with low levels of hyperactivity (N = 38) performed a modified stop-signal anticipation task,…

Evidence points to the possibility of promoting executive functions (EF) through school interventions. Little is known, however, about the effectiveness of this type of intervention in situations of social vulnerability. This study investigated the effectiveness of an EF intervention program applied with a sample of preschool children, in a…

Current research has reported the beneficial effects of mindfulness-based interventions (MBIs) on general domains of cognition and behavior among children. The present study is the first meta-analysis with controlled studies investigating the pre-post change effects of MBIs on two widely experienced behaviors in childhood education, namely…

The aim of the study is to examine the predictive effect of self-regulation on peer relations. Data were collected from 3486 children. Of the study sample, 1736 were girls (49.9%) and 1747 were boys (50.1%). All the children were from high SES families and attending private preschools in 10 cities in Turkey. The results showed that all peer…

Research Findings: A successful transition from preschool to elementary school requires a high level of behavioral adaptation. The aim of our study was to analyze child-related factors in preschool that facilitate a positive behavioral adaptation in the transitional period to elementary school. A cluster analysis was conducted with the data from…

The present study examined how different externalizing child behaviors (i.e., hyperactivity, conduct problems) were uniquely associated with teachers' mental representations of relationships with individual children. Participants were 61 teacher-child dyads from typical Dutch elementary schools. Using a two-wave design, teachers first reported…

This paper explores the incidence of children's social, emotional and behavioural difficulties within areas of multiple deprivation in one Local Authority in Wales and the potential effects of targeted training interventions on the quality of adult-child interactions. The quality of adult-child interaction was measured pre and post-test using the…

Fetal alcohol spectrum disorder (FASD) is one of the leading causes of intellectual disabilities. Self-regulation in FASD is poorly defined and interpreted in varying ways, making informed clinical decision making difficult. The objective is to operationally define self-regulation in the FASD population using the Walker and Avant (2005)…

Background: The impact of chronic stressors like the COVID-19 pandemic is likely to be magnified in adolescents with pre-existing mental health risk, such as attention-deficit/hyperactivity disorder (ADHD). This study examined changes in and predictors of adolescent mental health from before to during the COVID-19 pandemic in the Southeastern and…

To date, the phenotypic significance of EEG abnormalities in patients with ASD is unclear. In a population affected by ASD we aimed to evaluate: the phenotypic characteristics; the prevalence of EEG abnormalities; the potential correlations between EEG abnormalities and behavioral and cognitive variables. Sixty-nine patients with ASD underwent…

Background: Children's sleep problems and self-regulation problems have been independently associated with poorer adjustment to school, but there has been limited exploration of longitudinal early childhood profiles that include both indicators. Aims: This study explores the normative developmental pathway for sleep problems and self-regulation…

Adolescence is a period in everybody's life that is usually referred to as "time that everybody must go through" or "parents' hell". Transition between childhood and adulthood is indeed of great importance in everybody's life, but it is usually accompanied with a variety of questions, problems, dilemmas and a constant need to…
