Some reports suggest that there is an increase in the number of children identified as having developmental language impairment (Bercow, 2008). yet resource issues have meant that many speech and language therapy services have compromised provision in some way. Thus, efficient ways of identifying need and prioritizing intervention are required.…

Background: Primary school math skills form a basis for academic success down the road. Different math skills have different antecedents and there is a reason to believe that more complex math tasks require better self-regulation. Aims: The study aimed to investigate longitudinal interrelations of calculation and problem-solving skills, and…

Difficulties suppressing previously encountered but currently irrelevant information from working memory characterize less skilled comprehenders in studies in which they are matched to skilled comprehenders on word decoding and nonverbal IQ. These "extreme" group designs are associated with several methodological issues. When sample size…

The main focus of this study was to refine our understanding of the link between English proficiency and mainstream acculturation in adolescent Chinese immigrants. The sample consisted of 112 adolescents in grades 7-12 living in urban areas in southern Ontario, Canada. English proficiency was assessed individually using standardised tests of…

This study investigated whether the amount and timing of group-based childcare between birth and 51 months were predictive of cognitive development at 51 months, taking into account other non-parental childcare, demographic characteristics, cognitive development at 18 months, sensitive parenting and a stimulating home environment. Children's…

The present study investigated the contribution of morphological and cognate awareness to the development of English and French vocabulary knowledge among young minority and majority language children who were enrolled in a French immersion program. Participating children (n = 75) were assessed in English and French on measures of morphological…

Children with autism spectrum disorder present with a variety of social communication deficits such as atypicalities in social gaze and verbal and non-verbal communication delays as well as perceptuo-motor deficits like motor incoordination and dyspraxia. In this study, we had the unique opportunity to study praxis performance in deaf children…

West Syndrome is a severe, early-onset epilepsy syndrome, with significant implications for subsequent neurological and cognitive development. While most children with a prior diagnosis of West Syndrome initially follow a normal developmental trajectory, there is evidence of subsequent emergence of clusters of difficulties, including autism…

Cognate awareness is the ability to recognize the cognate relationship between words in two etymologically related languages. The current study examined the development of cognate awareness and its contribution to French (second language) reading comprehension among Canadian French immersion children. Eighty-one students were tested at the end of…

Research Findings: This study examined the heterogeneity in Spanish-speaking children's (N = 117; M age = 53 months; SD = 5 months; 57% boys) vocabulary and letter-word skills in English and Spanish after one year of preschool and the extent to which early self-regulation abilities (i.e., executive function and effortful control) were associated…

This book presents original, empirical data from quantitative and qualitative research studies in the field of language learning aptitude, ability, and individual differences. It does so from the perspectives of Second Language Acquisition, psychology, neuroscience and sociolinguistics. All studies included in the book use a similar and uniform…

Background: Diagnosis of "specific" language impairment traditionally required nonverbal IQ to be within normal limits, often resulting in restricted access to clinical services for children with lower NVIQ. Changes to DSM-5 criteria for language disorder removed this NVIQ requirement. This study sought to delineate the impact of varying…

This study investigated associations between school-readiness patterns of Latino students and their subsequent academic achievement. After identifying a subgroup of students with academic risk at kindergarten entry who showed signs of later average or better academic skill development, academic data were gathered to explore how this group of…

Through a review of the literature on mathematical learning disabilities (MLD) and low achievement in mathematics (LA) we have proposed a model classifying mathematical skills involved in learning mathematics into four domains (Core number, Memory, Reasoning, and Visual-spatial). In this paper we present a new experimental computer-based battery…

This study compared bilingual and monolingual school beginners on measures of simple and complex verbal working memory and receptive and expressive vocabulary. The aim was to determine whether the tests of working memory are fairer measures of language ability than the vocabulary tests for bilingual children when tested in their second language.…
