By age 2, children are developing foundational language processing skills, such as quickly recognizing words and predicting words before they occur. How do these skills relate to children's structural knowledge of vocabulary? Multiple aspects of language processing were simultaneously measured in a sample of 2-to-5-year-olds (N = 215): While older…

Codeswitching is a common feature of bilingual language practices, yet its impact on word learning is poorly understood. Critically, processing costs associated with codeswitching may extend to learning. Moreover, verbs tend to be more difficult to learn than nouns, and the challenges of learning verbs could compound with processing costs…

Although much is known about supporting preschoolers' alphabet knowledge, less is known about instructional moves that support preschoolers' narrative comprehension or how preschoolers' developing cognitive skills may support their narrative comprehension development. This school-university partnership project examined relations of preschoolers'…

Young children can exploit the syntactic context of a novel word to narrow down its probable meaning. This is "syntactic bootstrapping." A learner that uses syntactic bootstrapping to foster lexical acquisition must first have identified the semantic information that a syntactic context provides. Based on the "semantic seed…

Purpose: This study investigated the attentional tendencies of preschool children with developmental language disorder (DLD) and their typical language (TL) peers during a word learning task to examine what visual properties of novel objects capture their attention. Method: Twelve children with DLD and 12 children with TL completed a novel name…

This study reports the results of a Give-X task investigating the comprehension of ordinal and cardinal numbers in monolingual Russian-speaking children. Data collected from 36 children between the ages of 4;06 and 5;10 provided evidence that Russian learners follow the well-attested pattern for cardinal acquisition, but that children use a…

We studied English-learning children's ability to learn the meanings of novel words from sentences containing truth-functional negation (Exp1) and to use the semantics of negation to inform word meaning (Exp2). In Exp1, 22-month-olds (n = 21) heard dialogues introducing a novel verb in either negative-transitive "("Mary didn't blick the…

Purpose: The aim of this study was to identify variability in word-learning mechanisms used by late-talking children using a longitudinal study design, which may explain variability in late-talking children's outcomes. Method: A cohort of typically developing children (n = 40) and children who were classified as late-talking children at age 2;0…

Rehearsal is a form of self-talk used to support short-term memory. Historically, the study of rehearsal development has diverged from the study of self-talk more generally. The current experiment examines whether two characteristics of self-talk (impact of task difficulty and self-talk's narrative vs. planning purpose) are also observed in…

How do children succeed in learning a word? Research has shown robustly that, in ambiguous labeling situations, young children assume novel labels to refer to unfamiliar rather than familiar objects. However, ongoing debates center on the underlying mechanism: Is this behavior based on lexical constraints, guided by pragmatic reasoning, or simply…

Children often hear many new words in one conversation, and yet word learning research overwhelmingly focuses on how children learn and retrieve the meanings of single words. The current experiment tests how the number of labeled objects affects preschoolers' novel word referent selection immediately after encoding and after a one-week delay.…

Research on young English language learners has been gaining popularity in recent years, but to this day remains underdeveloped. The present study aimed to add to this body of research by exploring the effects of visual arts activities implemented via comprehension and compared to more commonly used flashcard activities implemented via…

When referring to objects, adults package words, sentences, and gestures in ways that shape children's learning. Here, to understand how continuity of reference shapes word learning, an adult taught new words to 4-year-old children (N = 120) using either clusters of references to the same object or no sequential references to each object. In three…

One primary problem in extremely preterm children is the occurrence of atypical language development. The aim of this study was to explore the components of language (articulatory phonetics, lexicon and syntax) in comprehension and production in extremely preterm children between the 4th and 5th year of age. The language section of the Preschool…

Assessing vocabulary knowledge is an important part of establishing language proficiency in bilingual children. The crosslinguistic lexical tasks (CLTs) provide a framework for testing vocabulary development in three-to-six year-olds using a standard procedure and comparable items for multiple languages. This study describes the development of the…
