Purpose: The goal of this study was to examine potential mediators of the relationship between developmental language disorder (DLD) status and executive function performance. Method: Participants included preschoolers, of whom 80 met the diagnostic criteria for DLD and 103 were categorized as having typical language abilities. Participants'…

Children's word problem competence is a major determinant of their career prospects. Abstract word (AW) comprehension and equal sign knowledge (ESK) are considered the foundation of discourse comprehension and pre-algebra skills, respectively. However, the link between AW and ESK in relation to the meaningful agent representative information…

Purpose: Speech perception is facilitated by listeners' ability to dynamically modify the mapping to speech sounds given systematic variation in speech input. For example, the degree to which listeners show categorical perception of speech input changes as a function of distributional variability in the input, with perception becoming less…

Mutualism is a developmental theory that posits positive reciprocal relationships between distinct cognitive abilities during development. It predicts that abilities such as language and reasoning will influence each other's rates of growth. This may explain why children with Language Disorders also tend to have lower than average non-verbal…

Background & aims: Individuals with non- or minimally verbal autism (nvASD) are primarily characterized by a severe speech production deficit, with speech limited to no or only a few words by school age. Significant unclarity remains over variability in language profiles across the lifespan, the nature of the language impairment seen, and…

As we listen to speech, our ability to understand what was said requires us to retrieve and bind together individual word meanings into a coherent discourse representation. This so-called semantic unification is a fundamental cognitive skill, and its development relies on the integration of neural activity throughout widely distributed functional…

Purpose: Little is known about the specific nature of language abilities of autistic adolescents and young adults with language impairment (LI), limiting our knowledge of developmental trajectories and ability to develop efficacious speech/language supports. An important first step is establishing proof of concept of identification of LI in this…

Predictors of expressive grammar were compared in formal and naturalistic assessment tasks for children with typically developing (TD) language and with Developmental Langauge Disorder (DLD). Standardized expressive language assessments were administered to 110 preschoolers. The parents of these children reported whether or not they were concerned…

Word retrieval and lexical organization were explored in 16 Danish children with slight to severe hearing loss (HL), 11 children with developmental language disorder (DLD), and 25 typically developing (TD) children in the age range of 7 to 12 years. There is a special focus on children with HL with and without language difficulties compared with…

Background: Early and effective treatment for children with developmental language disorder (DLD) is important. Although a growing body of research shows the effects of interventions at the group level, clinicians observe large individual differences in language growth, and differences in outcomes across language domains. A systematic…

In Canada, approximately 12% of school-aged children are enrolled in French Immersion (FI), with some provinces estimating close to 30%. FI programs are intended to produce bilingual individuals who can functionally communicate in both of Canada's official languages. Yet, we are currently underinformed as to how to identify children with French…

The primary aim of this study was to evaluate and compare alternative modalities and stimuli used to measure receptive vocabulary skills in autistic children who are minimally verbal. This study systematically compared participants' outcomes on three different receptive vocabulary assessment conditions: a low-tech assessment that used a stimulus…

Background: The purpose of this study was to examine the relationship between selective visual attention (SVA), reading decoding, listening comprehension and reading comprehension in children with and without a reading disorder. Methods: We used longitudinal data from the Avon Longitudinal Study of Parents and Children. We split children into four…

This study investigated bilingualism effects on the production of focus in 5- to 9-year-old Cantonese-English bilingual autistic children's L1 Cantonese, compared to their monolingual autistic peers as well as monolingual and bilingual typically developing children matched in nonverbal IQ, working memory, receptive vocabulary and maternal…

Purpose: The aim of this study was to examine the relationship between functional communication skills, underlying speech, language, and cognitive impairments and school-based speech pathology services in students with cerebral palsy (CP). Method: Thirty-five participants with CP who had Individualized Education Programs (IEPs) were classified…
