Although identifying the referents of single words is often cited as a key challenge for getting word learning off the ground, it overlooks the fact that young learners consistently encounter words in the context of other words. How does this company help or hinder word learning? Prior investigations into early word learning from children's…

Vocabulary knowledge plays a critical role in supporting text comprehension and broader learning across the school day. While school offers opportunities to build vocabulary knowledge, studies have shown that very little time is devoted to vocabulary instruction at the elementary level. This may be, in part, because educators commonly report being…

Purpose: The word learning of preschool-age children with developmental language disorder (DLD) is improved when spaced retrieval practice is incorporated into the learning sessions. In this preregistered study, we compared two types of spacing--an expanding retrieval practice schedule and an equally spaced schedule--to determine if one of these…

Bilingual environments present an important context for word learning. One feature of bilingual environments is the existence of translation equivalents (TEs)--words in different languages that share similar meanings. Documenting TE learning over development may give us insight into the mechanisms underlying word learning in young bilingual…

Recent work has investigated the origin of infant colour categories, showing pre-linguistic infants categorise colour even in the absence of colour words. These infant categories are similar but not identical to adult categories, giving rise to an important question about how infant colour perception changes with the learning of colour words. Here…

Word learning is typically studied as a problem in which children need to learn a single meaning for a new word. And by most theories, children's learning is itself guided by the assumption that a new word will have only one meaning. However, the majority of words in languages are polysemous, carrying multiple related and distinct meanings. Here,…

In word learning, learners need to identify the referent of words by leveraging the fact that the same word may co-occur with different sets of objects. This raises the question, what do children remember from "in the moment" that they can use for cross-situational learning? Furthermore, do children represent pictures of familiar animals…

In this theoretical review, evidence for the link between spoken and written word knowledge is summarised, highlighting the specific hypotheses posed in this field and the extent to which they are informative regarding causation. A brief overview of major theories of orthographic learning draws attention to how each characterises the role of oral…

There are calls for developing ways to teach language that can inspire and motivate students to study additional languages. While previous research has pointed toward benefits of arts-based activities in language learning, combining language and dance has mainly been studied with younger language learners. Contextualized within the course…

Toddlers vary widely in the rate at which they develop vocabulary. This variation predicts later language development and school success at the group level; however, we cannot determine which children with slower vocabulary development in the second year will continue to have difficulty. In this article, I argue that this is because we lack…

Third language (L3) lexical acquisition is still underexplored. In this article I overview theoretical and empirical evidence on L3 lexical acquisition and the role of cross-linguistic influence (CLI) in learning L3 words. I explain the mechanism of CLI as resulting from language co-activation in the multilingual learner's/user's mind.…

Studies on multilingual word learning have focused on identifying a bilingual advantage over monolingual peers, paying little attention to the relationships between bilinguals' existing vocabulary size and novel word learning. This study compared monolingual and bilingual school-age children on word learning tasks in familiar and unfamiliar…

Lower vocabulary in German is repeatedly reported for students with Turkish migration background attending school in Germany. We investigated whether in students of Turkish descent (a) learning vocabulary is impaired when the teacher activates the negative stereotype that students with Turkish family language learn less well and (b) whether a…

We investigated indexical variation as a variable that promotes second language (L2) vocabulary learning across language modalities. In three experiments, we presented Catalan Sign Language signs (Experiments 1a and 1b), pseudowords (Experiment 2), and English words (Experiment 3) to participants in three conditions that varied in the number of…

Recent years have seen a flourishing of Natural Language Processing models that can mimic many aspects of human language fluency. These models harness a simple, decades-old idea: It is possible to learn a lot about word meanings just from exposure to language, because words similar in meaning are used in language in similar ways. The successes of…
