We explored associations among the core behavioural features and developmental/cognitive abilities of 155 autistic children, assessed between ages 13-67 months and again around 1-year later to understand predictive directionality. Bidirectional, cross-domain association was apparent, albeit with stronger direction of effect from earlier cognition…

Purpose: Developmental language disorder (DLD) is a lifelong condition associated with poorer outcomes than neurotypical peers, yet relatively little is known about long-term quality of life in DLD. This preliminary study adopts a neurodiversity-informed approach by exploring "self-reported" quality of life in an adolescent and young…

A growing body of evidence demonstrates that individual differences in declarative memory may be an important predictor of second language (L2) abilities. However, the evidence comes from studies using different declarative memory tasks that vary in their reliance on verbal abilities and task demands, which preclude estimating the size of the…

This study examined the independent contribution of morphological awareness and orthographic awareness in reading comprehension, controlling for working memory and reading fluency in Arabic-speaking children. Participants (N = 244) from grades four and five, were classified into typical comprehenders (n = 207) and poor comprehenders (n = 37). All…

Child temperament is a predictor of non-verbal ability (i.e. thinking and problem-solving skills that do not fundamentally require verbal language production and comprehension). Given that temperament scores might vary depending on whether the reporter is a parent or a teacher, this study analyses (a) whether those reports are different and (b)…

Purpose: The current study addresses a gap in the literature regarding syntactic development of adolescent boys with fragile X syndrome (FXS) and Down syndrome (DS). Specifically, we ask whether syntactic skills plateau or continue to change during adolescence for these groups and whether the profile of syntactic change differs between boys with…

We aimed to investigate the effects of phonological awareness -- PA, rapid automatised naming -- RAN, visuospatial and verbal working memory -- WM and executive functions -- EF on the reading and arithmetic skills of children with low- to medium-performance levels. Participants were 472 Brazilian children from 3rd to 5th grades. Quantile…
