Purpose: The Arabic verb system features a nonlinear root and pattern derivational morphology. Previous studies suggest that young Arabic and Hebrew speakers' early verb use is based on semantic complexity rather than derivational morphological structure. The present study examines the role of morphological and semantic complexity in the emergence…

Background: The home literacy environment (HLE) has rarely been examined for individuals with neurodevelopmental disorders, including individuals with Williams syndrome and Down syndrome. Method: The current study surveyed carers of individuals with Down syndrome (n = 48) and Williams syndrome (n = 18) in the United Kingdom (UK). Results: The…

Introduction: Mental health concerns have been noted to be highly prevalent for youth with intellectual disability (ID), with or without autism spectrum disorder (ASD). The purpose of the current study was to examine a Canadian sample of youth with ID, with or without ASD, to explore caregiver-reported percentages, predictors, and treatment…

This study investigates typing skill acquisition in Japanese children with developmental dyslexia (DD) and other developmental disorders (ADHD, ASD). Given that phonological processing difficulties impair reading and writing, typing may serve as an alternative skill for written expression. Sixty-one students (ages 7-18) participated in five typing…

This cross-sectional study explored stressful situations of caregivers related to life events of their children suffering from neurodevelopmental disorders along with potential contributing factors. A total of 906 caregivers of children with diagnosed neurodevelopmental disorder, from eight administrative districts and two city corporation areas…

Background: Future planning has emerged as a global issue for families of individuals with intellectual and developmental disabilities due to the longer lives and limited long-term services and supports in the adult disability system. While it has received greater attention, most future planning studies only included parents of individuals with…

Background: Previous research, although scarce, has indicated that the general public is still relatively unaware of developmental language disorder (DLD), one of the most common (neuro)developmental disorders. Raising awareness would increase timely involvement in intervention procedures. Aims: To examine public awareness of DLD in the…

Motor abnormalities are highly prevalent in children with autism spectrum disorder and are strongly predictive of adaptive functioning. Despite the documented sex bias in the prevalence of the disorder, the impact of sex differences on motor abnormalities has been overlooked. The goal of this study was to investigate differences in the motor…

This study aimed to explore the prevalence of challenging behaviors (CBs) associated with students with severe developmental disabilities (SDDs) as rated by their teachers. The study also attempted to examine whether the occurrence and intensity of CBs might depend on certain socio-demographic variables. Data was collected using a questionnaire to…

This study explored the differences in mean length of utterance (MLU) and mean length of the five longest utterances (MLU5) between 5-6-year-old Mandarin-speaking children, and between typically developing children and children with developmental language disorders (DLD). Eighty-nine typically developing children and 35 children with a DLD…

Background: Limited data exist on problematic sexual behaviour (PSB) in youth with developmental disabilities in South Korea. Method: Sixty-one parents of children with intellectual disabilities or autism spectrum disorder (aged 13-30) reported children's PSB and emotional, behavioural, cognitive, and interpersonal factors. The frequency of PSB in…

Cross-cultural studies have suggested that reading deficits in developmental dyslexia (DD) can be moderated by orthographic depth. To further explore this issue and assess the moderating role of orthographic depth in the developmental cognitive trajectories of dyslexic and typical readers, we systematically reviewed 113 studies on DD that were…

Spelling difficulties often occur in children with developmental language disorder (DLD), the extent and drivers of these difficulties are underspecified. Meta-analyses were conducted to address this gap. We identified child-based factors (age, language spoken, profile of difficulties) and task-based factors (text production or dictation) as…

Purpose: This study examined whether monolingual German-speaking preschool children with developmental language disorder (DLD) were facilitated by the presence of case-marking cues in their interpretation of German subject and object "welcher" ("which")-questions, as reported for their typically developing peers. We also…

The goal of the present study was to assess the family quality of life (FQOL) in families with children with developmental disabilities in Bosnia and Herzegovina. We examined the FQOL in relation to parents' demographic variables (gender, age, employment status), children's gender and age, type of children's disability (mild and moderate…
