Both classic thought experiments and recent empirical evidence suggest that children frequently encounter new words whose meanings are underdetermined by the extralinguistic contexts in which they occur. The role that these referentially ambiguous events play in children's word learning is central to ongoing debates in the field. Do children learn…

Children can acquire novel word meanings by using pragmatic cues. However, previous literature has frequently focused on in-the-moment word-to-meaning mappings, not delayed retention of novel vocabulary. Here, we examine how children use pragmatics as they learn and retain novel words. Thirty-three younger children (mean age: 5.0, range: 4.0-6.0,…

Purpose: This study investigated the dimensionality of language in bilingual children using measures of semantics and morphosyntax in English and Spanish. Method: Participants included 112 Spanish-English bilingual children ages 4-8 years from a wide range of language abilities and dominance profiles. Using measures of semantics and morphosyntax…

Children's early grammatical constructions, e.g., SVO, exhibit a learning curve with cumulative verb types (CVT) increasing exponentially. According to Ninio (2006), the fact that learning curves, though nonlinear, can be modelled by a continuous regression suggests instant generalisation. Moreover, differences in initial verbs across children…

Learning the meaning of a verb is challenging because learners need to resolve two types of ambiguity: (1) word-referent mapping--finding the correct referent event of a verb, and (2) word-meaning mapping--inferring the correct meaning of the verb from the referent event (e.g., whether the meaning of an action word is TURNING or TWISTING). The…

Purpose: The purpose of this study was to determine if the Vocabulary Acquisition and Usage for Late Talkers (VAULT) intervention could be efficaciously applied to a new treatment target: words a child neither understood nor said. We also assessed whether the type of context variability used to encourage semantic learning (i.e., action or object)…

This study examined the acquisition of numeral classifiers in 120 monolingual Japanese children. Previous research has argued that the complex semantic system underlying classifiers is late acquired. Thus, we set out to determine the age at which Japanese children are able to extend the semantic properties of classifiers to novel items/situations.…

Combining adjective meaning with the modified noun is particularly challenging for children under three years. Previous research suggests that in processing noun-adjective phrases children may over-rely on noun information, delaying or omitting adjective interpretation. However, the question of whether this difficulty is modulated by semantic…

Numerous developmental findings suggest that infants and toddlers engage predictive processing during language comprehension. However, a significant limitation of this research is that associative (bottom-up) and predictive (top-down) explanations are not readily differentiated. Following adult studies that varied predictiveness relative to…

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…

Classrooms with multilingual students are rich spaces for enacting linguistically sustaining practices that encourage students to use all their language resources. When teachers have some knowledge of their students' home languages, they can facilitate making connections across languages which strengthens students' language development. In this…

Five-to-six-year-olds' abilities to detect and solve ambiguities in spoken language have been found to be a predictor of their later reading abilities in first-to-third grade. However, the origins of this relationship remain unclear. Success in ambiguity detection may be reflective of overall language attainment, which varies with socioeconomic…

Extensive research has shown that children's early words are learned through sensorimotor experience. Thus, early-acquired words tend to have more concrete meanings. Abstract word meanings tend to be learned later but less is known about their acquisition. We collected meaning-specific concreteness ratings and examined their relationship with…

This study investigates the impact of structured vocabulary review on vocabulary acquisition among middle-grade students (grades 6-8) using an experimental, parallel design. Twenty-four classrooms (310 students) were randomly assigned to review different sets of academic vocabulary. Students completed 20 weeks of the Word Generation curriculum,…

The present study complemented the extant second language (L2) Age of Acquisition (AoA) normative database by providing over 3500 English L2 words on objective AoA and over 2600 English L2 words on subjective AoA. The correlation between the objective and subjective L2 AoA confirmed the validity of the present database. The objective L2 AoA was…
