In individuals with autism spectrum disorder (ASD), de novo mutations have previously been shown to be significantly correlated with lower IQ but not with the core characteristics of ASD: deficits in social communication and interaction and restricted interests and repetitive patterns of behavior. We extend these findings by demonstrating in the Simons Simplex Collection that damaging de novo m...

Difficulties in handwriting are often reported in children with developmental coordination disorder, and they represent an important element in the diagnosis. The present study was aimed at investigating the relation between motor coordination and handwriting skills, and to identify differences in handwriting between children without and with coordination difficulties. In particular, we asked w...

Use of automatically reinforced stereotypy as reinforcement has been shown to be successful for increasing socially desirable behaviors in persons with intellectual disabilities (Charlop, Kurtz, & Casey, 1990; Hanley, Iwata, Thompson, & Lindberg, 2000; Hung, 1978). A component analysis of this treatment was conducted with 3 adolescents who had been diagnosed with autism, and then extended by (a...

BACKGROUND Poor motor and social skills as well as peer victimization are commonly reported in both ADHD and autism spectrum disorder. Positive relationships between poor motor and poor social skills, and between poor social skills and peer victimization, are well documented, but the relationship between poor motor skills and peer victimization has not been studied in psychiatric populations. ...

Developmental coordination disorder (DCD) is often called a motor learning deficit. The question addressed in this paper is whether improvement of motor skills is just a matter of mere practice. Without any kind of intervention, children with DCD do not improve their motor skills generally, whereas they do improve after task-oriented intervention. Merely offering children the opportunity to pra...

The Effectiveness of Computerized Visual-Motor Skills Training on the Severity Symptoms Children with Attention Deficit / Hyperactivity Disorder

BACKGROUND Comorbidity among developmental disorders such as dyslexia, language impairment, attention deficit/hyperactivity disorder and developmental coordination disorder is common. This study explores comorbid weaknesses in preschool children at family risk of dyslexia with and without language impairment and considers the role that comorbidity plays in determining children's outcomes. MET...

OBJECTIVE To investigate associations between motor skills, exercise capacity and cognitive functions, and evaluate how they correlate to academic performance in mathematics and reading comprehension using standardised, objective tests. METHODS This cross-sectional study included 423 Danish children (age: 9.29±0.35 years, 209 girls). Fine and gross motor skills were evaluated in a visuomotor ...

abstract objective development is a complex process, completed over a specific period of time, through the maturation of the nervous system. it is affected by genetic, ethnic, nutritional, social, and economic factors; one of the environmental factors affecting the acquisition of motor skills in infants is the use of baby walkers. since this device is very commonly used for infants in our count...
