Individuals with mild intellectual disability (MID) were worse than their peers who typically develop in motor skills and attention-demanding assignments. In this study, effect of a 14-week physical activity and attention training practise on the motor skills, visual retention, perception and attention levels of students with MID were analysed.…

Visuo-spatial training is considered a promising approach to provide young children with a sound foundation for later mathematical learning. We developed and implemented a tablet-based visuo-spatial intervention in kindergarten classrooms aiming to foster the development of children's visuo-spatial and numerical abilities. A sample of N = 125…

Because math knowledge begins to develop at a young age to varying degrees, it is important to identify foundational cognitive and academic skills that might contribute to its development. The current study focused on two important, but often overlooked skills that recent evidence suggests are important contributors to early math development:…

Introduction: This study explored the variables of executive functioning (EF) that permitted the evaluation of EF both at home and at school. The objective was to compare the results of the evaluations of these functions in children aged 5 to 6 years, and see to what extent these variables predicted mathematics performance best. Method: Sixty-six…

West Syndrome is a severe, early-onset epilepsy syndrome, with significant implications for subsequent neurological and cognitive development. While most children with a prior diagnosis of West Syndrome initially follow a normal developmental trajectory, there is evidence of subsequent emergence of clusters of difficulties, including autism…

The relations among various spatial and mathematics skills were assessed in a cross-sectional study of 854 children from kindergarten, third, and sixth grades (i.e., 5 to 13 years of age). Children completed a battery of spatial mathematics tests and their scores were submitted to exploratory factor analyses both within and across domains. In the…

Aim: To describe neuropsychological disturbances and the developmental course associated with cerebellar cortical dysplasia (CCD). Method: The neuroimaging findings from 10 children (five males, five females; aged 3-10y) with CCD were reviewed and classified. These children all underwent clinical neurological examination and neuropsychological…

Because of ongoing neuromaturation, youth with chronic alcohol/substance use disorders (AUD/SUD) are at risk for cognitive decrements during young adulthood. We prospectively examined cognition over 10 years based on AUD/SUD history. Youth (N = 51) with no AUD/SUD history (n = 14), persisting AUD/SUD (n = 18), or remitted AUD/SUD (n = 19) were…

Occupational therapists assess fine motor, visual motor, visual perception, and visual skill development, but knowledge of the relationships between scores on sensorimotor performance measures and handwriting legibility and speed is limited. Ninety-nine students in grades three to six with learning and/or behavior problems completed the Upper-Limb…

This study explored the cognitive performance of children with Attention Deficit/Hyperactivity Disorder (ADHD) and/or Developmental Coordination Disorder (DCD) using the Wechsler Intelligence Scale for Children-IV. Participants were 62 children with ages between 9 years 8 months and 12 years 7 months. These children were placed into one of the…

Relatively brief interactions with a commercial game that involved blocks and matching patterns are shown to cause a significant improvement in children's performances on the WISC-R Block Design subtest. Two experiments are described using 10-year-old children in game and no-game conditions. (Author/CM)

Applies the analytic technique of maximum likelihood factor analysis to the intercorrelations of the Wechsler Intelligence Scale for Children-Revised's subtests as a means for assessing more or less differentiation and integration. (HOD)

Analyzed WISC-R profiles of 42 conduct problem children to generate hypotheses concerning the children's intellectual strengths and weaknesses. Used a variety of subtest groupings to interpret ability patterns. Findings revealed relative strengths in perceptual organization skills, and weaknesses in skills that involve sequencing, memory, and…

This speech offers a guide to identifying and teaching high-risk children, those who exhibit a lag in development severe enough to be a handicap in learning. The high-risk children focused on are those whose developmental lag is frequently not recognized until they fail in school. The two major areas of neurodevelopmental learning disorders are in…

This cross-sectional study explored whether participation, from early childhood, in play involving different cognitive abilities predicts visuo-spatial achievement at ages 9, 12, and 15. Based on parental assessment, prior and present practice of spatial manipulation play was found to be consistently more frequent in boys than in girls; the…
