Purpose: The goal of this work was to examine the semantic and syntactic properties of the vocabularies of autistic and non-autistic infants and toddlers to see if children in these two groups know different kinds of words. We focused on both receptive and expressive vocabularies. For expressive vocabulary, we looked only at the "active"…

Purpose: Children's vocabulary and syntactic skills vary upon school entry in depth and breadth, persistently influencing academic performance, including reading. Enhancing early communicative abilities through multisensory, playful, and conversational experiences is essential and will benefit children's school readiness. This study investigated…

Purpose: To avoid misdiagnosis with developmental language disorder (DLD) in bilingual children, it is recommended to evaluate both languages. However, unlike their monolingual peers, bilingual children acquire their heritage language under adverse input conditions. Focusing on Levantine Arabic, the study evaluates the clinical utility of a…

Pragmatics lies at the point where language meets the social world and encompasses both the linguistic and the social dimensions of communication. However, the relationship between pragmatic abilities, other language skills, and socio-cognitive aspects such as mentalizing is still a matter of wide debate. This study sets out to investigate the…

Purpose: This cross-sectional study aimed to depict expressive language profiles and clarify lexical-grammatical interrelationships in Mandarin-speaking preschoolers with autism spectrum disorder (ASD) during the administration of the simplified Chinese Psychoeducational Profile--Third Edition screening. Method: We collected naturalistic language…

Background and aims: Nongenerative speech is the rote repetition of words or phrases heard from others or oneself. The most common manifestations of nongenerative speech are immediate and delayed echolalia, which are a well-attested clinical feature and a salient aspect of atypical language use in autism. However, there are no current estimates of…

This study explored performance on expressive and receptive graphic symbol tasks and spoken comprehension by individuals who use augmentative and alternative communication (AAC) as well as the relationship of performance with participants' skills and characteristics. Participants were 19 children and youth (aged 5- to 18-years-old) who used aided…

Background: Difficulties in language development are related to social and emotional problems, lower academic outcomes, and lower quality of life from childhood to adolescence. These grave consequences might be significantly reduced by timely identification and professional support. The introduction of systematic screening for language delay (LD)…

Children with autism spectrum disorder often have significant language delays. But do they learn language differently than neurotypical toddlers? We compared the lexical skills of 64 preverbal and minimally verbal children with autism spectrum disorder to 461 vocabulary-size-matched typically developing toddlers. We also examined social features…

To explore the roles of character recognition, expressive vocabulary, and syntactic awareness in deaf and hard of hearing (DHH) students' reading fluency, 52 Chinese DHH students (mean age = 13.29 years) in elementary school participated in the present study. The results showed that character recognition, expressive vocabulary, and syntactic…

Background: There is empirical evidence that a developmental language disorder (DLD) in early childhood leads to behaviour problems. However, it is still not clear how changes in language proficiency in these children influence the presence of behaviour problems. Aims: The aim of this study is to examine if changes in language proficiency are…

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…

Thirty-one children with and without autism spectrum disorder were asked to draw the meaning of 10 basic concepts. Following each drawing, children explained their drawing to the experimenter. Transcripts of the drawing task were coded for children's use of personal pronouns and internal state terms. Children's use of on- and off-task comments…

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…

Background: We discuss a free software system (Computerized Language Analysis [CLAN]) that can enable fast, thorough, and informative language sample analysis (LSA). Method: We describe methods for eliciting, transcribing, analyzing, and interpreting language samples. Using a hypothetical child speaker, we illustrate use KidEval to generate a…
