To address the variability of naturalistic developmental behavioral intervention outcomes, the current study sought to isolate the effects of the instructional strategies of caregiver-mediated naturalistic developmental behavioral interventions. In this comparative efficacy trial, mothers of 111 autistic children (18-48 months) were randomized to…

The aim was to investigate the staff's language support towards children in Swedish preschools after eight weeks of structured language support. This study took place after an initial study of six weeks' language support. To identify support of Language Learning Environment, Opportunities and Interactions an observation-tool was used. Structured…

This meta-analysis examined associations between the quantity and quality of parental linguistic input and children's language. Pooled effect size for quality (i.e., vocabulary diversity and syntactic complexity; k = 35; N = 1,958; r = .33) was more robust than for quantity (i.e., number of words/tokens/utterances; k = 33; N = 1,411; r = .20) of…

This paper discusses the innovative research method of using body-worn cameras for capturing speech and experiences of 3- to 5-year olds in English early years settings. The strengths and weaknesses will be discussed in this multiple case study approach to capturing the quality of speech from young children (n = 43). Adopting an interactionist…

Purpose: Sentence diversity is a measure of early language development that has yet to be applied to individuals with autism spectrum disorder (ASD). The primary aim of this study was to identify whether children with ASD show change in sentence diversity over 6 months of treatment with Naturalistic Developmental Behavioral Intervention (NDBI).…

Audio-visual recording and location tracking produce enormous quantities of digital data with which researchers can document children's everyday interactions in naturalistic settings and assessment contexts. Machine learning and other computational approaches can produce replicable, automated measurements of these big behavioral data. The…
