This study examined the influence of linguistic input on the development of productive and receptive skills across three fundamental language domains: lexico-semantics, syntax, and phonology. Seventy-one (35 female) Basque-Spanish bilingual children were assessed at three time points (Fall 2018, Summer 2019, Winter 2021), between 4 and 6 years of…

This study investigated the feasibility of a vocabulary-based teacher intervention to increase preschool teachers' production of complement clauses (e.g. "I wonder if we can put the monkey in the tree") in teacher-children play interactions. Using a multiple baseline across participants design we measured the impact of an intervention…

Spontaneous verbal repetition is part of early adult-child conversational interchanges. However, most of the studies devoted to verbal repetition analyse child-produced and adult-produced repetition independently. The aim of this study is to analyse verbal repetition sequences that are extended by children and adults participating in turns. We…

Little analytical scrutiny has been devoted to teacher accommodation of academic language at the early childhood level, despite being a critical school-level factor to consider when addressing at-risk learners' academic needs. The present study investigates how fifteen Head Start teachers support three components of academic language during…

Researchers consistently report that children from low socioeconomic status (SES) families have, on average, smaller vocabularies as assessed by measures of existing vocabulary knowledge than children from higher SES families. Yet, few studies have examined the word-learning process of children from low SES families. The present study was an…

This article evaluates the extent to which pre-schoolers' picture books can be viewed as a form of enriched linguistic input. Twenty best-selling picture books were analysed in terms of syntactic constructions and compared with a sample of Child Directed Speech. The findings of the study demonstrate the prevalence of canonical utterances (i.e.…

Research indicates that linguistic input from teachers may affect child vocabulary development in preschool and beyond (Dickinson & Tabors, 2001). Currently, there is little research on the relationship between specific teacher language use in individual interactions on child language outcomes for preschool children at risk for academic delays.…

Existing work on the acquisition of syntax has been concerned mainly with the early stages of syntactic development. In the present study we examine later syntactic development in children. Also, existing work has focused on commonalities in the emergence of syntax. Here we explore individual differences among children and their relation to…
