By adulthood, most males with fragile X syndrome (FXS) require support to navigate day-to-day settings. The present study cross-sectionally: (1) characterized the profile of daily living skills in males with FXS and (2) examined associated participant characteristics (i.e., fragile X mental retardation protein [FMRP] expression, nonverbal…

This study aimed to determine the effect of exercise training on mental adaptation levels and communication skills in mentally handicapped individuals who were at an educable level. Based on this purpose, the Performance Determination Form for Individuals with Intellectual Disabilities, which was created in 2018 within the scope of the Ministry of…

Purpose: Chromosome 16p11.2 deletion syndrome (OMIM #611913) is a rare genetic condition resulting from the partial deletion of approximately 35 genes located at Chromosome 16. Affected people exhibit a variable clinical profile, featuring mild dysmorphisms, motor problems, developmental delay, mild intellectual disability (ID), socialization…

Background & aims: Due to the complexity of early diagnostic decision making, we examined the predictive value of an early diagnostic classification and early abilities on later best estimate diagnosis for 22 clinically referred children with language difficulties. Methods and procedures: Four years after initial evaluation (Time 1), the…

Purpose: Multiple factors impact reading acquisition in individuals with reading disability, including genetic disorders such as Williams syndrome (WS). Despite a relative strength in oral language, individuals with WS usually have an intellectual disability and tend to display deficits in areas associated with reading. There is substantial…

Background: Language assessment is a key element of evaluations of children and adolescents with neurodevelopmental disorders (NDDs). The present study examined the validity of a gaze-based receptive language index (RLI) in predicting language test results.Method: Participants included toddlers, pre-school, and school age children and adolescents…

Many Early Intensive Behavioral Intervention (EIBI) curricula recommend teaching receptive responding before targeting expressive responding (Leaf & McEachin, 1999; Lovaas, 2003). However, a small literature base suggests that teaching expressive responses first may be more efficient when teaching children with ASD and other developmental…

Purpose: The aim of this study was to investigate language growth in individuals with fragile X syndrome (FXS) from early childhood to adolescence and the influence of maternal responsivity on language growth. Method: We conducted a longitudinal analysis of language development in 55 youths (44 males, 11 females) with FXS. Data collection spanned…

Background: This study aimed to compare developmental courses of structural and pragmatic language skills in school-aged children with Williams syndrome (WS) and children with idiopathic intellectual disability (IID). Comparison of these language trajectories could highlight syndrome-specific developmental features. Method: Twelve monolingual…

Background: Individuals with Williams syndrome (WS) show a disharmonic linguistic profile with a clear pattern of strengths and weaknesses. Despite their sociable nature, atypical socio-communicative abilities and deficits in communication and relationship with others have been found. Aim: The aim of the present study was to investigate whether…

Background: There is a dearth of research or inconsistency in findings of behaviours among children with autism spectrum disorder (ASD) and children with intellectual disability (ID) as well as children who are typically developing (TD). This study compared 7 behavioural domains of 96 behaviours among Chinese children. Method: There were 803…

This report describes a project that uses existing data sets to describe the population of students with significant cognitive disabilities and known or suspected dual sensory loss. It includes students with suspected dual sensory loss because students with significant cognitive disabilities are reported to have unidentified sensory loss (Erickson…
