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…

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…

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…

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…

Background: Pivotal response treatment (PRT) is suggested to be an effective treatment for children with autism spectrum disorder (ASD). Objectives: We aimed to compile evidence examining the effectiveness of PRT on social communication, social interaction, and repetitive behavior for children with ASD. Methods: We performed a systematic and…

The relation between caregiver follow-in utterances with verbs presented in different states of dyadic engagement and later child expressive verb vocabulary in children with autism spectrum disorder (ASD) was examined in 29 toddlers with ASD and their caregivers. Caregiver verb input in follow-in utterances presented during higher order supported…

Purpose: This longitudinal study assessed continuity and stability of productive language (vocabulary and grammar) and discourse features (turn-taking; asking and responding to questions) during mother-child play. Method: Parent-child language use in 119 Spanish-speaking, Mexican immigrant mothers and their children at two ages (M = 2.5 and 3.6…

Younger biological siblings of children with autism spectrum disorder (sibs-ASD) are at a heightened risk for developing communication disorders, such as autism spectrum disorder or language impairment. Two strategies that are theoretically motivated as potentially beneficial for sibs-ASD are follow-in comments and providing input in episodes of…

Studies of language development in children with autism spectrum disorder (ASD) have been primarily focused on the influence of child-based factors such as autism traits, IQ, and initial language skills. Yet the findings of these studies are inconclusive. There has, moreover, been little research compared the relative influences of child-based…

The aim of this study was to develop a coding scheme that enables researchers and practitioners to conduct a detailed analysis of the communicative behavior of young children with significant cognitive and motor developmental delays. Currently, there is a paucity of methods to do conduct such an analysis. For the study, video observations of three…

Schools are the portal through which many children with autism spectrum disorder access early intervention. Collaborating with teachers can be an effective way to implement evidence-based practices. In this study, teachers learned to embed strategies from the Joint Attention, Symbolic Play, Engagement, and Regulation intervention into the standard…

Contemporary educational policies both at international and national levels acknowledge the educational rights of all children and their inclusion in mainstream educational practices. Like other children at risk, children with disabilities have opportunities to access mainstream education but their participation is not always realised in practice.…

The Internet, new media and social change have created issues requiring digital citizenship education, particularly within the socio-cultural context of Chinese education. Recent digital citizenship standards for education developed by organizations such as the International Society for Technology in Education (ISTE) highlight the importance of…
