Objective: This study aimed to objectively assess signs of hyperactivity in adults suspected of having ADHD, addressing potential sex bias in diagnosis. Methods: About 13,179 (49% female) adults with an average age of 33 years with ADHD and 1,910 (41% female) adults with an average age of 36 years without ADHD were included. Motor activity was…

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…

This study investigated the effectiveness of applying a smartphone to reduce the hyperactive/impulsive behaviors of 3 students with attention deficit hyperactivity disorder (ADHD) in class. A smartphone that can simultaneously provide vibration and visual text prompts was adopted in this study to remind the participants when they exhibited…

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,…

Children with externalizing behavior problems are likely to show poor school achievements, problems in social interactions with teachers and peers and an elevated school-related stress. Though class climate is a meaningful variable to explain school achievements and aspects of emotional well-being, there are hardly any studies that consider class…

Ability-grouping has been studied extensively in relation to children's academic, but not emotional and behavioral outcomes. The sample comprised 7259 U.K. children (50% male) with data on between-class and within-class ability-grouping at age 7. Peer, emotional, hyperactivity, and conduct problems were measured at ages 7, 11, and 14 years.…

We examine the relationships of executive functioning problems (EFP) to academic cheating in a sample of 855 adolescents. Participants completed assessments of inattention, hyperactivity, and depression using the BASC-2, as well as peer-reports of externalizing behavior. After controlling for known predictors of cheating (e.g., demographics and…

Previous research, using a variable-centered approach, points out to the possibility that not all victims of bullying have the same mental health and social profile. The aim of the current investigation was to explore whether there are different profiles--related to emotional, behavioral, and social problems--of pure victims of bullying and…

Background: Attention-deficit hyperactivity disorder (ADHD) is a risk for learning. Because ADHD commonly includes behaviours of inattention and behaviours of hyperactivity/impulsivity, how the two types of behaviours independently affect children's academic competence remains poorly understood. Aims: To investigate the impact of behaviours of…

Autistic adults commonly experience sensory reactivity differences. Sensory hyperreactivity is frequently researched, whilst hyporeactivity and seeking, and experiences across domains, e.g., vision, are often neglected. Therefore, we aimed to understand more about the sensory experiences of autistic adults. We conducted a mixed-methods study,…

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…

Introduction: Individuals with intellectual disabilities (ID) are at heightened risk of behavioral problems. Methods: This study investigated differences in the severity of challenging behaviors (CBs) among individuals with IDs at varying life stages. Data were collected from parents' retrospective interviews. Surveys were completed by 47 parents…

Infants at elevated likelihood of developing autism display differences in sensory reactivity, especially hyporeactivity, as early as 7 months of age, potentially contributing to a developmental cascade of autism symptoms. Caregiver responsiveness, which has been linked to positive social communication outcomes, has not been adequately examined…

Various factors at the individual and school levels contribute to the impairment of academic achievement. We examined whether academic class composition, measured as average class achievement and class heterogeneity (variance in achievement within class), moderates the associations of inattentiveness and hyperactivity/impulsivity with academic…
