Dyslexia is one of the most studied learning disorders. Despite this, its biological basis and main causes are still not fully understood. Electroencephalography (EEG) could be a powerful tool in identifying the underlying mechanisms, but knowledge of the EEG correlates of developmental dyslexia (DD) remains elusive. We aimed to systematically…

Mental illness, and its assessment and treatment, is a concern for caregivers and professionals working with people with intellectual disability (ID), as well as a cause of distress and disability for people with ID. Research in this area is hindered by difficulties associated with recognizing symptoms of mental illness and tracking their changes.…

Background: Developmental language disorder (DLD) is common in children, but little is known about its association with quality of life (QoL) in middle childhood. QoL is a complex construct, aligning with an individual's sense of well-being and is related to functional limitations associated with DLD. Biopsychosocial models of disability account…

Background: Myotonic dystrophy type 1 (DM1) is a slowly progressive multi-systemic disease with an autosomal-dominant inheritance caused by a mutation on chromosome 19 (19q13.3). Aims: To explore speech characteristics in a group of individuals with the congenital and childhood-onset forms of DM1 in terms of intelligibility, speech-sound…

This study explores social outcomes for adults with autism spectrum disorder (ASD) in comparison to adults with developmental disabilities other than ASD by investigating the relationships between the constructs Social Participation and Relationships, Social Determination, and Personal Control. Structural equation modeling (SEM) was used to test a…

Timing ability is essential for common everyday performance. The aim of the study was to compare timing abilities and temporal aspects of handwriting performance and relationships between these two components among children with Developmental Coordination Disorders (DCD) and a control group. Forty two children, 21 diagnosed as DCD and 21 with…

Social avoidance and anxiety are prevalent in fragile X syndrome (FXS) and are potentially mediated by the amygdala, a brain region critical for social behavior. Unfortunately, functional brain resonance imaging investigation of the amygdala in FXS is limited by the difficulties experienced by intellectually impaired and anxious participants. We…

Executive functions are crucial for efficient daily functioning. However, the contribution of executive functions to the participation in daily life activities of children, have been inadequately studied. The study aimed to examine the unique contribution of executive functions, beyond motor ability, to the diversity and independence of children's…

To evaluate evidence for motor impairment specificity in autism spectrum disorder (ASD) and attention deficit/hyperactivity disorder (ADHD). Children completed performance-based assessment of motor functioning (Movement Assessment Battery for Children: MABC-2). Logistic regression models were used to predict group membership. In the models…

Children with developmental coordination disorder (DCD) have deficits in working memory, but little is known about the everyday memory of these children in real-life situations. We investigated the everyday memory function in children with DCD, and explored the specific profile of everyday memory across different domains. Nineteen children with…

The present study examined the link between brain hemisphericity and dyslexia in secondary school students, using the Preference Test (PT), a widely used self-report index of preferred hemisphere thinking styles. The hypothesis was that differences would be revealed between the dyslexic group and their peers in hemispheric preference. A total of…

Problem Statement: Because communication skills, particularly pragmatic skills, are fundamental for living an independent life in society, these skills are vital to the quality of life of individuals with developmental disabilities (DD) and their families. Studies of the pragmatic skills of individuals with DD can provide important insights into…

The behaviors frequently displayed by students with autism can place them at risk for overly reactive behavior interventions with unwanted side effects. The current study examined the level of intrusiveness of behavioral treatments developed for 198 students with disabilities from 13 different states. Results demonstrated that students diagnosed…

The longitudinal relationship between attention deficit hyperactivity disorder (ADHD) and violent criminality has been extensively documented, while long-term effects of autism spectrum disorders (ASDs), tic disorders (TDs), and obsessive compulsive disorder (OCD) on criminality have been scarcely studied. Using population-based registers of all…

The aim of this study was to validate a questionnaire on mastery motivation (task and effort) for use with Chinese preschool children in Hong Kong. A parent version and a teacher version were developed and evaluated. Participants included 457 children (230 boys and 227 girls) aged four and five years old, their preschool teachers and their…
