Although vocabulary size is thought to index children's language abilities, an increasing body of work suggests that regularities in children's vocabulary composition, particularly the proportion of shape-based nouns (e.g., cup), support language development. Here we examine initial vocabulary composition in children with hearing loss following…

Drawing on recent scholarship integrating usage-based linguistics (UBL) and conversation analysis (CA) in the investigation of second language development, this paper reports on a microanalysis tracing one adult learner's recurring, increasingly frequent, and diverse use of the multiword expression "det er sant" (it/that is true) (DES)…

Research examining relations between language skills and social competence has yielded mixed findings. Three meta-analyses investigated links between language skills (overall, receptive, and expressive) and social competence in 2- to 12-year-old children. Data from 130 studies representing 62,120 children (M age at language assessment = 4.70…

Purpose: Children with Down syndrome often have poor speech intelligibility, which can mask expressive language competence; this, in turn, can lead to serious misconceptions about overall competence and intellectual abilities. Although aided augmentative and alternative communication (AAC) can be used to bridge these gaps, children with Down…

This study compared the use of delivering a single instruction (e.g., Who is it?) versus varied instructions (e.g., What's their name? Who is this? What about this one?) when teaching three children diagnosed with autism spectrum disorder (ASD) novel expressive label targets via direct telehealth. The present investigation utilized an adapted…

The present study explored developmental differences in preschoolers' use of reported speech and internal state language in personal narratives. Three-, four-, and five-year-olds attending a laboratory preschool shared 204 stories about 'a time when you were happy/sad'. Stories were audio-recorded, transcribed, and coded for reported speech…

Social anxiety is a prevalent issue among college students, often leading to poor academic and psychosocial adjustment. Expressive writing has shown promise as a brief, cost-effective intervention for improving mental and physical health. This study investigated the effects of a 15-min expressive writing session on the social performance of mildly…

Background: Prelinguistic communication complexity refers to the use of different communication forms such as eye gaze, gestures and vocalisations and the degree to which these forms are coordinated and how directed to a communication partner. To date, little is known about the relationship between prelinguistic communication complexity and…

Background: The evidence on the effect of age on the receptive and expressive language skills of individuals with Down syndrome is inconclusive. Recent research highlights the relevance of having tools to detect age-related changes in language skills. Method: Data were collected on 45 adults with Down syndrome. All were assessed with the Peabody…

Purpose: The present study explored the extent to which early prelinguistic communication skills predict expressive language in toddlers with autistic siblings (Sibs-autism), who are known to be at high likelihood for autism and language disorder, and a comparison group of toddlers with non-autistic older siblings (Sibs-NA). Method: Participants…

Sonority and its language-universal sonority-sequencing principle (SSP) define an important dimension of phonological grammar which aids in the segmentation of words into syllables (Clements in Pap Lab Phonol 1:283-333, 1990). Studies have yielded contradictory findings on sonority and SSP phonotactics in lexical perception of speech by children…

Researchers have demonstrated that dialogue-based intelligent tutoring systems (ITS) can be effective in assisting students in learning. However, little research has attempted to explore the necessity of equipping dialogue-based ITS with one of the most important capabilities of human tutors, that is, maintaining polite interactions with students,…

This study investigated the acquisition of early expressive vocabulary among young children who are deaf and hard-of-hearing (DHH; n = 68) using auditory technology (hearing aids and cochlear implants). Parents completed a standardized vocabulary checklist, which allowed analyses of (i) the size of their child's spoken vocabulary; (ii) composition…

The present study investigated the relationship between lexicon and grammar in individuals who use graphic symbol-based aided augmentative and alternative communication (AAC). Data came from 60 transcripts of generalization sessions that were part of two previous intervention studies, aimed at improving the expressive vocabulary and grammar of 12…

During the COVID-19 pandemic, lecturers wore masks which covered facial cues. In two studies, we examined students' ability to comprehend both factually and inferentially presented information when the speaker's facial cues were or were not available and when delivered with or without expressive prosody. While comprehension was not affected by the…
