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)…

Purpose: This study evaluates the impact of temporal synchrony between maternal touch and speech on children's early language development. It investigates whether the proportion of word-touch co-occurrence, overlap, and alignment precision in maternal input influences language acquisition, hypothesizing that such synchrony boosts infants'…

Purpose: Conversational latency entails the temporal feature of turn-taking, which is understudied in autistic children. The current study investigated the influences of child-based and parental factors on conversational latency in autistic children with heterogeneous spoken language abilities. Method: Participants were 46 autistic children aged…

Children's exposure to talk about conceptual categories plays a powerful role in shaping their conceptual development. However, it remains unclear when parents begin to talk about categories with young children and whether such talk relates to children's language skills. This study examines relations between parents' talk about conceptual…

Objective: The current study tested an expressive writing intervention aimed at reducing alcohol use and sexual risk behavior among college women that consume alcohol. Methods: A 2 X 2 mixed between- within-subjects experimental design was utilized to test the effect of expressive writing on alcohol use and sexual risk behavior over time among…

Background: Related to the target group of young children with a significant cognitive and motor developmental delay, the aims of this study were to obtain more insight into (the interrelations between) several characteristics of these children's expressive communicative behaviour and to explore associations between child behaviour, partner…

We compared dyad-focused maternal speech (protoconversations and maternal speech describing the dyad) in interactions of mothers with their twin and singleton infants. Nine twins and nine singletons, coming from urban areas of Crete (Greece), were video-recorded at home in spontaneous face-to-face interactions with their mothers, from the 2nd to…

Improving social communication is a frequent goal of early autism services. However, it is unclear whether existing models of social communication align with the perspectives and priorities of key stakeholders, including parents, teachers, and expert clinicians. Stakeholder perspectives on social communication characteristics and priorities for…

Previous studies have shown that caregivers' sensitive, responsive interactions with young children can boost language development. We explored the association between caregivers' sensitivity and the vocabulary development of their 8-to-36-month-olds during COVID-19 when family routines were unexpectedly disrupted. Measuring caregivers'…

Minimal expressions are at the heart of interaction: Interjections like "Huh?" and "Mhm" keep conversations flowing by establishing and reinforcing intersubjectivity among interlocutors. Crosslinguistic research has identified that similar interactional pressures can yield structurally similar words (e.g., to initiate repair…

Looking to the mouth of a talker early in life predicts expressive communication. We hypothesized that looking at a talker's mouth may signal that infants are ready for increased supported joint engagement and that it subsequently facilitates prelinguistic vocal development and translates to broader gains in expressive communication. We tested…

Background: Early-language skills vary and are among the best predictors of later social and academic outcomes. High-quality early interaction supports strong early-language skills. Identifying modifiable sources of variability in early interaction quality is critical to determining intervention need, developing effective caregiver coaching, and…

The development of copying behaviours of a group of infants from 9 to 15 months of age is analysed. These behaviours are classified according to their type (mimetic or imitated) and function (instrumental, social or hybrid). The function of the behaviours is derived from observable indicators linked to dyadic interaction. Mimetic behaviours are…

This dissertation asks what young children do with style at a time when their social and linguistic worlds begin to expand beyond the home, into the peer group. Grounded in a yearlong ethnography of a preschool classroom in the San Francisco Bay Area, I show how play moved gradually from indoors to outdoors as children got older. This shift…

The use of interactive technologies has been demonstrated to enhance verbal and non-verbal communication, as well as the social interaction tendencies of children with Autism Spectrum Disorder (ASD). We examined effects of using Virtual Voice Assistant (VVAs) in children with ASD with respect to two outcomes: speech skills and social interaction…
