The diagnosis of attention deficit hyperactivity disorder (ADHD) distinguishes two dimensions of symptoms, inattention and hyperactivity-impulsivity for ages 3 to adulthood. Currently, no separate classification for preschool-age children exists, whereas preliminary research suggests that the two-factor structure of ADHD may not match the…

This study investigates the relationship between sensory processing patterns and behavioral patterns in children. The population consisted of all children in Tehran city. Participation included 229 school and 155 preschool children. We collected data using the Sensory Profile School Companion and Conners Teacher Rating Scale. Results showed that…

Objective: Despite strong evidence that inattentive and hyperactive/impulsive behaviors are associated with mathematical difficulties in school-age children, little research has been conducted to examine the link between these constructs before the start of formal education. The purpose of this study was to examine how different manifestations of…

We identified clusters of atypical sensory functioning adults with ASC by hierarchical cluster analysis. A new scale for commonly self-reported sensory reactivity was used as a measure. In a low frequency group (n = 37), all subscale scores were relatively low, in particular atypical sensory/motor reactivity. In the intermediate group (n = 17)…

Research Findings: Using data from 3,250 participants in the Early Childhood Longitudinal Study, Birth Cohort, we used structural equation modeling to investigate whether family routines (e.g., bedtime routine, reading routine) established in preschool predict children's school readiness (i.e., academic skills, social-emotional skills, and…

Background: Attention-deficit/hyperactivity disorder (ADHD) symptoms and mathematics ability are associated, but little is known about the genetic and environmental influences underlying this association. Methods: Data came from more than 6,000 twelve-year-old twin pairs from the UK population-representative Twins Early Development Study. Parents…

Objective: The goal of this study was to (a) investigate the association between nonprescription stimulant use (NPSU) and risky behaviors, including risky sex, driving, financial behaviors, and drug use and (b) collect preliminary evidence on mechanisms that may link NPSU to risky behaviors. Participants: A sample of 555 college students was…

The objectives of this study were (a) to evaluate parental stress in parents of children with autism spectrum disorders (ASD group) and compare it with the stress in parents of children with typical development (comparison group); (b) to study the relationship between parental stress, autism severity, and both verbal and performance IQ; and (c) to…

Introduction: Despite the clear relevance of the Student-teacher relationship, studies have rarely encompassed subjects with special education needs. Our study focused on the differences perceived by teachers in their relationships with these students. Method: We described the results obtained with different groups of children with special…

The link between behavior problems and low academic achievement is well established, but few studies have examined longitudinal relations between early externalizing behaviors before school entry and low academic achievement following transition to formal schooling. Early inattention has been particularly overlooked, despite strong associations…

This study aims to examine social competence of Chinese immigrant children and its associations with age, length of attendance in childcare, gender, generational status and proficiencies in English and Mandarin Chinese. One hundred Mandarin-speaking children aged three to five years from 15 childcare centres in Sydney were assessed by normed…

The present longitudinal study aimed to investigate the influence of ADHD symptoms on reading development in elementary schoolchildren. To this end, repeated assessments of ADHD symptoms (teacher ratings of inattention, hyperactivity, and impulsivity) and reading achievement (standardized tests of decoding speed and text comprehension) were…

This study investigates self-rated mental health in terms of psychological problems, protective factors and health-related quality of life (HRQOL) in a nationally representative sample of adolescents (n = 6813) aged 11-17 involved in violence with varying frequency. Using MANCOVA and ANCOVA, youth with single and multiple histories of violent…

Data on students' perceptions of teacher social support, academic functioning, and social-emotional functioning were collected from a sample of 796 7th and 8th grade middle school students using the Child and Adolescent Social Support Scale (CASSS; Malecki, Demaray, & Elliott, 2000), Iowa Tests of Basic Skills (ITBS) and school records, and…

Previous studies suggest that individuals with Williams syndrome (WS), a rare genetically based neurodevelopmental disorder, show specific weaknesses in visual attention and response inhibition within the visuospatial domain. Here we examine the extent to which impairments in attentional control extend to the visuomotor domain using a…
