Choosing which words to teach is a key consideration for language teachers and materials writers. Some studies have shown that teaching words in semantically related clusters can make learning more difficult. However, others argue it is the physical similarity of the referents of words that causes confusion. Importantly, studies have employed…

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…

Nonverbal behavior can impact language proficiency scores in speaking tests, but there is little empirical information of the size or consistency of its effects or whether language proficiency may be a moderating variable. In this study, 100 novice raters watched and scored 30 recordings of test takers taking an international, high stakes…

Background: Word-to-text integration (WTI) can be challenging for second-language (L2) learners, although it can positively contribute to reading comprehension. The present study examined the role of WTI, after controlling for decoding, vocabulary and morphosyntactic awareness, in predicting English as an L2 reading comprehension development in…

This study revisits the roles of different aspects of phonological vocabulary knowledge in second language (L2) listening. Japanese learners of English (n = 114) completed the TOEIC Listening test and three phonological vocabulary tests assessing (a) ability to recognize the meanings of aural forms (meaning recognition), (b) ability to recall the…

This study investigates the use of formulaic sequences (FS) in academic writings of Chinese learners of English as a foreign language across different levels of studies at a public university in China. Frequency-based formulas were retrieved from a corpus of student academic texts written at five time points between Year 1 and Year 3. The…

This study used event-related potential (ERP) and retrieval practice effect paradigm to investigate the neurocognitive mechanisms underlying the retrieval practice effect in a third language (L3) vocabulary learning. Thirty-five Chinese (First Language, L1)-English (Second Language, L2) bilinguals without prior knowledge of French (L3) studied 120…

Besides explicit inference of word meanings, associating words with diverse contexts may be a key mechanism underlying vocabulary learning through reading. Drawing from distributional semantic theory, we developed a text modification method called reflash to facilitate both word-context association and explicit inference. Using a set of left and…

Few studies aimed to disentangle different aspects of vocabulary depth (VD) knowledge and examine their contribution to second-language (L2) reading comprehension. To fill this gap, this study distinguished between two VD aspects, that is, semantic network knowledge and polysemous knowledge; and tested how they, together with vocabulary size (VS),…

This corpus-based study investigates the similarities and differences among the three synonymous adjectives: "careful," "cautious," and "wary" in terms of genre distribution, collocational patterns, semantic preference, and semantic prosody. Data were drawn from the Corpus of Contemporary American English (COCA). The…

Developing L2 learners' productive mastery of vocabulary is a challenging task. Recent research has called for greater attention to understanding how receptive vocabulary may be transformed for productive use (Schmitt, 2019). Using a design-based research methodology, this study investigated adult ESL learners' productive oral vocabulary…

This meta-analysis aims to investigate gamification's impact on improving tertiary-level second-language learners' lexical repertoire. Forty-seven peer-reviewed works were evaluated for this analysis. The analysis focused on determining the effectiveness of gamified learning environments in the context of improving vocabulary and learning and…

This study analyzes four English synonyms -- clear, obvious, apparent, and evident -- concentrating on meanings, distribution across genre, collocations, and semantic preference and prosody. The data were drawn from learner's dictionaries and the Corpus of the Contemporary American English (COCA). It was discovered that the four synonyms share the…

Various aspects of semantic features drive early vocabulary development, but less is known about how the global and local structure of the overall semantic feature space influences language acquisition. A feature network of English words was constructed from a large database of adult feature production norms such that edges in the network…

Age of Acquisition (AoA) scores approximate the age at which a language speaker fully understands a word's semantic meaning and represent a quantitative measure of the relative difficulty of words in a language. AoA word lists exist across various languages, with English having the most complete lists that capture the largest percentage of the…
