Many children grow up hearing multiple languages, learning words in each. How does the number of languages being learned affect multilinguals' vocabulary development? In a pre-registered study, we compared productive vocabularies of bilingual (n = 170) and trilingual (n = 20) toddlers aged 17-33 months growing up in a bilingual community where…

Others' emotional expressions affect individuals' attention allocation in social interactions, which are integral to the process of word learning. However, the impact of perceived emotions on word learning is not well understood. Two eye-tracking experiments investigated 78 British toddlers' (37 girls) of 29- to 31-month-old retention of novel…

The purpose of the study was to examine word learning in preschool children from families who differed in socioeconomic status (SES). Preschool children (N = 58) were assigned to SES groups based on maternal education and completed a dynamic assessment of explicit word learning 2 times. At the first administration, no SES-group differences were…

It was still true that some children came to school with a smaller vocabulary than their peers (David, 2010, Duff & Brydon, 2020; Templin, 1957; White, Graves, & Slater, 1990). If students did not have enough word knowledge to access the correct meanings of the words they read in text, they failed to comprehend those texts and struggled to…

Young children seem to pick up words quickly, almost effortlessly, through various media in the early years. Studies have shown that storybooks, TV, screen media, and ebooks can all be sources for incidental word learning without formal instruction. Yet, typically, research has investigated learning from a single medium in isolation or in…

The present study aimed to investigate whether and how Chinese single character reading and 2-character word reading can reflect somewhat different processes. Tasks of Chinese rapid automatized naming (RAN), morphological awareness, phonological awareness, orthographic knowledge, along with vocabulary knowledge and nonverbal intelligence tasks,…

The account that word learning starts in earnest during the second year of life, when infants have mastered the disambiguation skills, has recently been challenged by evidence that infants during the first year already know many common words. The preliminary ability to rapidly map and disambiguate linguistic labels was tested in Italian-speaking…

Children can learn words incidentally from stories. This kind of learning is enhanced when stories are presented both aurally and in written format, compared to just a written presentation. However, we do not know why this bimodal presentation is beneficial. This study explores two possible explanations: whether the bimodal advantage manifests…

This study investigates the levels of social language and vocabulary characteristics of three- to six-year-old children with autism in Vietnam. The research is based on analysis of the developmental assessment reports of 151 children with autism, and 42 parents' reports on their children's vocabulary (recorded using the Child Word Inventory form).…

This study examines whether children acquiring Tseltal (Mayan) demonstrate a noun bias -- an overrepresentation of nouns in their early vocabularies. Nouns, specifically concrete and animate nouns, are argued to universally predominate in children's early vocabularies because their referents are naturally available as bounded concepts to which…

The current study set out to examine to what degree age of acquisition (AOA), defined as a learner's first intensive exposure to a second language (L2) environment, mediates the final state of postpubertal, spoken vocabulary attainment. In Study 1, spontaneous speech samples were elicited from experienced Japanese users of English (n = 41) using…

Students with reading disabilities generally know fewer words (breadth) with less in-depth knowledge of those words (depth) than typical students. The present study examined the effects of a "moderately rich vocabulary instruction" in which both breadth and depth of vocabulary are addressed. Nineteen U.S. 4th- and 5th-grade students with…

Engaging in frequent, meaningful conversation during the early years of schooling is foundational for children's literacy development. Specifically, developing oral language through daily conversations is essential for language comprehension, and eventually, reading comprehension. In this article, we discuss how teachers can use the…
