Purpose: We measure typically developing monolingual child Spanish speakers' lexical development with a range of standard expressive and receptive tests. We also measure their comprehension of sentences with the existential quantifier "algunos" "some" to determine their abilities to generate "some, but not all" scalar…

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…

This study assessed the effect of adjectives and noun premodifiers on L2 noun phrase comprehension and error types among English Language Learners. We also examined the correlation between L2 noun phrase comprehension and L2 reading comprehension, as well as the contribution of L2 noun phrase comprehension to L2 reading comprehension. One hundred…

This study explores the effects of receptive derivational affix knowledge, derivative frequency, part of speech, and vocabulary breadth on production of derivatives. Twenty-one speakers of English as a first language and 107 learners of English as a second language were asked to produce derivatives for 90 prompt words on a decontextualized…

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…

Growing up in the digital era, young children are exposed to numerous educational applications and programs, some with well-designed curricula and others focused more on entertainment or game-like qualities. With the increasing popularity of mobile language-learning applications among young children, this dissertation raises a crucial question: do…

When linguistic input contains inconsistent use of grammatical forms, children produce these forms more consistently, a process called "regularization." Deaf children learning American Sign Language from parents who are non-native users of the language regularize their parents' inconsistent usages. In studies of artificial languages…

For elementary learners of Japanese, one of the main difficulties in reading is to distinguish words written in kana. This paper reports on a survey of elementary level learners with two different levels of proficiency to investigate the effectiveness of Japanese graded readers with parts of speech color-coded to distinguish nouns, verbs,…

This paper examined to what extent causal explanation speaking tasks (CESTs) are cognitively appropriate for assessing young language learners' (YLLs) L2 speaking. Ninety-six YLLs (48 from Grade 4 and 6 each) in China performed two CESTs in both L1 (Chinese) and L2 (English). They also completed receptive and productive L2 vocabulary size tests.…

Dialogic reading during shared book reading between adults and children is an effective way to promote vocabulary acquisition. However, there is limited research on what strategies parents are spontaneously using during book reading sessions, which are important to understand for optimizing parent training in dialogic reading. The current study…

Experimental research on the interface between second language vocabulary knowledge, including collocations, and translation competence is scarce. The present study investigates the role played by three determinants of collocation knowledge (knowledge level -- recall versus recognition, congruency, and constituent word types) in the accuracy of…

Purpose: There are strong retention benefits when learners frequently test themselves during the learning period. This practice of repeated retrieval has recently been applied successfully to children's word learning. In this study, we apply a repeated retrieval procedure to the learning of novel adjectives by preschool-age children with…

Purpose: Recent findings in preschool children indicated novel adjective recall was enhanced when learned using repeated retrieval with contextual reinstatement (RRCR) compared to repeated study (RS). Recall was similar for learned pictures used during training and new (generalized) pictures with the same adjective features. The current study…

This study sought to explore the advanced lexicon, one of the hallmarks of text quality. To this end, we analysed the advanced lexicon deployed in the production of two types of texts -- a descriptive and an argumentative -- by Hebrew-speaking school children. Our study had two goals, the first to trace the developmental path of the use of…

Purpose: The aim of this study was to gain more insight into the linguistic characterization of dyslexia by investigating vocabulary acquisition. In a previous study, vocabulary at 17 months of age appeared to be related to familial risk (FR) of dyslexia. The aim of this study was to investigate how the differences in lexical composition further…
