To code-switch or not to code-switch? This is a dilemma for many bilingual language teachers. In this study, the influence of teachers' CS on bilingual children's language and cognitive development is explored within heritage language (HL) classes in Singapore. Specifically, the relationship between children's language output, vocabulary…

The present study examines the perceptual, linguistic, and social cues that were associated with preschoolers' (4;11) growth in word-learning during shared book-reading and guided play activities. Small groups of three preschoolers (n = 30) and one adult were video-recorded during an intervention study in which new vocabulary words were explicitly…

This study evaluated the development of vocabulary knowledge over the course of two academic years, beginning in preschool, in a large sample (N = 944) of language-minority children using scores from single-language vocabulary assessments and conceptual scores. Results indicated that although children began the study with higher raw scores for…

We explored the vocabulary and metaphor comprehension of learners of English as an additional language (EAL) in the first two years of UK primary school. EAL vocabulary knowledge is believed to be a crucial predictor of (reading) comprehension and educational attainment (Murphy, 2018). The vocabulary of five- to seven-year-old children with EAL…

This study is about the role of elicited verbal imitation in toddler word learning. Forty-eight toddlers were taught eight nonwords linked to referents. During training, they were asked to imitate the nonwords. Naming of the referents was tested at three intervals (one minute later [uncued], five minutes, and 1-7 days later [cued]) and recognition…

There is a noted advantage of dense neighborhoods in language acquisition, but the learning mechanism that drives the effect is not well understood. Two hypotheses--long-term auditory word priming and phonological working memory--have been advanced in the literature as viable accounts. These were evaluated in two treatment studies enrolling twelve…

Forty children, aged 1 ; 8-2 ; 0, participated in one of three training conditions meant to enhance their comprehension of the spatial term "under": the +Gesture group viewed a symbolic gesture for "under" during training; those in the +Photo group viewed a still photograph of objects in the "under" relationship; those in the Model Only group did…

Evaluates the effect of didactic techniques used during storybook reading on young children's acquisition of new vocabulary introduced in storybooks under three reading conditions: single-reading; repeated-reading and questioning. Findings suggest that didactic techniques used by adults have differential effects on preschoolers' receptive and…
