We examined how noun frequency and the typicality of surrounding linguistic context contribute to children's real-time comprehension. Monolingual English-learning toddlers viewed pairs of pictures while hearing sentences with typical or atypical sentence frames ("Look at the…" vs. "Examine the…"), followed by nouns that were…

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…

In spite of the proliferation of research studies on vocabulary knowledge, investigating the relationship between self-regulation, vocabulary size, and collocational knowledge among English as a Foreign Language (EFL) learners has received scant attention. The current study aimed to investigate whether vocabulary and collocation size can explain…

Three modes of deliberate vocabulary study were investigated to determine how well they assisted learners' recall of the meaning of target concrete nouns. Two modes of tablet-based augmented reality, one context-independent (AR1) and one context-dependent (AR2), were compared with each other and with paper-based word cards (WC) in the deliberate…

Research has shown that learning a known-and-unknown word combination leads to greater learning than learning an unknown word alone (Kasahara, 2010, 2011). These studies found that attaching a known adjective to an unknown noun can help learners remember the unknown noun. Kasahara (2015) found that a known verb can serve as an effective cue to…

The present study examines the mechanisms of lexical case acquisition in Russian by two-to-five-year-old Russian monolingual (n = 54) and Russian-English bilingual children (n = 38). Participants performed a picture-based sentence completion task. Sentences were constructed to elicit production of real Russian words (n = 24) and nonce words (n =…

While previous research has provided insights into vocabulary learning through extensive reading, the differential effects of word frequency and word class on active form and passive meaning word recognition remain less understood. By evaluating learners' post-test performance in active form recognition and passive meaning recognition, this study…

Research into vocabulary knowledge often differentiates between breadth (how many words a person knows) and depth (how well the words are known). Both theoretical categories are essential for understanding language learners' lexical development, but how the different aspects of vocabulary knowledge interconnect has not received the same attention…

Arabic is characterized by diglossia, which involves the use of two language varieties within a single speech community: Spoken Arabic (SpA) for everyday speech and Modern Standard Arabic (MSA) for formal speech and reading/writing. Earlier research suggests that some Arabic-speaking children with Autism spectrum disorder (ASD) might favor MSA…

Typically developing (TD) children, as young as four years of age, have demonstrated enhanced noun learning when orthographic representations are presented during learning tasks. This dissertation investigated the impact of orthographic support on word learning in diverse populations, focusing on children from a variety of clinical categories…
