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…

Background: Despite accumulated evidence that language development depends on basic cognitive processes, the balance in contributions of verbal and non-verbal cognitive skills to language abilities is still underexplored. Little is known about which cognitive measures best predict the degree of severity in children with language disorder (LD).…

The study examined storytelling prosody (i.e., prosodic variations in retelling a story) and the relation with oral language in Taiwanese preschool children. One hundred and twenty-eight preschool children aged 4 and 5 were recruited and given the following tasks: nonverbal intelligence, vocabulary, syntax, and storytelling prosody. Children's…

In this study, we investigated the direct and indirect associations of different cognitive-linguistic skills and Chinese reading comprehension in Hong Kong kindergarteners. We assessed 179 children's nonverbal IQ, cognitive-linguistic skills, word reading, listening comprehension, and reading comprehension. Results showed significant correlations…

This study investigated the executive functions (EF) of preschool children and their associations with emotional, linguistic, and cognitive skills, using parent and teacher reports. A total of 130 children aged 34 to 71 months participated. The preschool version of the Behavior Rating Inventory of Executive Function (BRIEF-P) was completed by both…

The purpose of the present research was to comprehensively assess the language abilities of Russian primary-school-aged children with Autism Spectrum Disorder (ASD), varying in non-verbal IQ, at all linguistic levels (phonology, lexicon, morphosyntax, and discourse) in production and comprehension. Yet, the influence of such non-language factors…

Purpose: The purpose of this study was to examine quality of life (QOL) and its relation to language skills in children with developmental language disorder (DLD). This was examined by comparing QOL to a control group of children with typical development (TD), as well as children with cochlear implants (CIs), who potentially struggle with language…

During human childhood, brain development and body growth compete for limited metabolic resources, resulting in a trade-off where energy allocated to brain development can decrease as body growth accelerates. This preregistered study explores the relationship between language skills, serving as a proxy for brain development, and body mass index at…

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…

Purpose: The aims of this study were to investigate the occurrence of stuttering behavior across time and to evaluate the relationship between stuttering behavior and language ability in children with Down syndrome. Method: A national age cohort of Norwegian first graders with Down syndrome (N = 75) participated in the study. Speech samples from a…

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…

The importance of early childhood narrative skills in social relationships and children's internal capacity is of utmost interest to be studied. This aim of this study is to examine how the social group functioning, narrative skills, school success and non-verbal intelligence are interconnected. This is a mixed design study with a sample of 109…

The study's purpose was to clarify the developmental characteristics of working memory in hard of hearing children on the basis of language ability and task variables. Eighty-three congenitally severely hard of hearing children in grades 3-9 attending Japanese elementary and junior high school were aggregated on the basis of grade and language…

This study examines whether, and how, multiple risks in early childhood are associated with an increased likelihood of a poor language or literacy outcome in early adolescence. Using data from 210 participants in the longitudinal Twins Early Developmental Study, we focus on the following risk factors at age 4: family risk, and poor language,…

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…
