Background: The longitudinal impact of fetal growth on attention problems in males and females is unclear. This study aims to evaluate the impact of fetal growth assessed by neonatal anthropometry throughout childhood and adolescence in males and females separately. Methods: We compared neonatal anthropometry (birth weight (BW), head circumference…

Background: Studies suggest that prosocial behavior, having high empathy and engaging in behaviors intended to benefit others, may predict mental health or vice versa; however, these findings have been mixed. The purpose of the current study was to examine the bidirectional relationships between prosocial behavior and dimensions of psychopathology…

Objective: This study examined the prospective relationship from student inattention symptoms to changes in their psychological need satisfaction (PNS) during their transition to secondary school. In doing so, it has explored whether this temporal association was moderated by teachers' involvement (TI). Method: A sample of 688 students (46% male;…

Objective: Attention Deficit Hyperactivity Disorder (ADHD) is characterized by inattention, hyperactivity, and impulsivity; however, other executive function dysregulation is common, including inhibition and working memory. This study aims to identify CT differences based on executive function performance in individuals with and without ADHD.…

Background: International literature has underlined the complex interplay between genetic and environmental variables in shaping children's emotional-behavioral functioning. Objective: This study aimed to explore the dynamic relationship between children's Dopamine Transporter (DAT1) genotype and methylation, and maternal and paternal affective…

The present study examined individual differences in the development of sustained attention across toddlerhood, as well as how these individual differences related to the development of language and sleep. Toddlers (N = 314; 54% male) were assessed at 30, 36, and 42 months using multiple measures of attention, a standardized language assessment,…

Objectives: This study investigated the unique associations of motor competence and ADHD risk status on school functioning. Additionally, this study examined the factor structure of the Bruininks-Oseretsky Test of Motor Proficiency, Short Form (BOT2-SF). Methods: Participants included early elementary school children (N = 202, M[subscript age] =…

This study investigated the relationship between mathematics difficulties and psychopathology in a large community sample (N = 881) of youth (8-18 years of age) in the United States. The primary aims of the study were to (a) test the associations between mathematics difficulties and specific components of internalizing, externalizing, attention,…

The mediators of real-world executive functions in autism during the transition into adulthood are mainly unknown. This study aimed to identify the mediators for the behavioral and cognitive domains of real-world executive functions in late adolescent and young adult autistic populations. We followed up 289 autistic children (aged 11.6 ± 3.8, male…

We tested whether adoptive parenting played a role in the association between pre-adoption experiences and children's adaptive (responsiveness) and maladaptive (internalizing and externalizing behavioral problems, attention and sleep problems) behavioral adjustment over time. Ten-year-old girls, adopted at 13 months from institutional care (n =…

While a considerable number of youth with autism spectrum disorder exhibit impaired self-regulation (dysregulation), little is known about the neural correlates of dysregulation in autism spectrum disorder. In a sample of intellectually able boys with autism spectrum disorder (further categorized as those with and without dysregulation) and…

Adults with autism spectrum disorder often experience co-occurring mental health problems such as attention-deficit/hyperactivity-disorder, as well as impairments in executive function. Sluggish cognitive tempo, a cluster of behaviors including slow processing, daydreaming, and mental fogginess, has been shown to be associated with…

Introduction: The primary aim of this retrospective study was to assess differential associations between sleep disturbances with externalizing/internalizing problems, ADHD profiles (inattention, hyperactivity/impulsivity), and social impairment among children with ADHD, autism spectrum disorder (ASD), and comorbid diagnoses (ASD+ADHD). Methods:…

The purpose of this study was to investigate the self-perception bias (SPB) in adolescents with attention-deficit hyperactivity disorder (ADHD). The SPB was defined as adolescent underestimation of their learning and behavior problems in comparison to parent- or teacher-reports or a standardized achievement test. The sample comprised 74…

In this study, we concurrently investigated 3 possible causes of dyslexia--a phonological deficit, visual stress, and a reduced visual attention span--in a large population of 164 dyslexic and 118 control French children, aged between 8 and 13 years old. We found that most dyslexic children showed a phonological deficit, either in terms of…
