Semantic diversity quantifies the similarity in the content of contexts a word has been experienced in. Four experiments investigated its effect on lexical and semantic judgments in 9- to 10-year-olds and adults. In Experiment 1, a cross-modal semantic judgment task, participants decided whether a visually presented word matched an audio…

The present study investigated the association between vocabulary size and depth of Iranian EFL learners at different language proficiency levels. Additionally, the extent that this relationship could be different for low-and high-word-frequency bands was probed. In so doing, the Word Associates Test (WAT), the Vocabulary Levels Test (VLT), the…

We have developed a program called Content Integrated Language Instruction for Adults, incorporating research-based practices in vocabulary and language instruction to facilitate a deep and broad understanding of complex content. A subset of words critical to comprehension of the subject matter is covered in each lesson, using group discussion and…

The study aimed to examine the relationship between morphological knowledge and reading comprehension ability among college-level English as a foreign language (EFL) students. One hundred and twenty-one students participated in this study and they completed two morphological knowledge measures (morpheme-form knowledge and morpheme-meaning…

Bilingual children's dominance can predict a variety of language and cognitive outcomes. The purpose of this study was to test the validity of parents' classifications of 3- to 6-year-old bilingual children's dominance against relative receptive vocabulary scores. In Study 1, the parents' classifications of Mandarin-English bilingual children's…

The purpose of this study is to examine whether a difference exists in TOEIC Bridge® Institutional Program scores between Japanese English as a Foreign Language (EFL) students at a technical college who did extensive reading (ER) for one year and those who did ER for two years. Furthermore, by dividing the students who experienced ER for two years…

The current study examined the extent to which cognitive fluency (CF) contributes to utterance fluency (UF) at the level of constructs. A total of 128 Japanese-speaking learners of English completed four speaking tasks--argumentative task, picture narrative task, reading-to-speaking task, and reading-while-listening-to-speaking task--and a battery…

Derivational morphology (DM) and how it can be assessed have been investigated relatively rarely in language learning and testing research. The goal of this study is to add to the understanding of the nature of DM knowledge, exploring whether and how it is separable from vocabulary breadth. Eight L2 (second or foreign language) English DM…

Education policy in England's schools is driven by the 'what works' agenda, characterised by interventions claiming to be scientifically objective and evidence-led. In this article I show how what works interventions reproduce anti-Black linguistic racism because to be perceived as someone who is 'working', racialised children must assimilate…

This dissertation presents four iterative experiments which explore the quantitative benefits of introducing linguistics to language learners. Previous work has connected exploration of linguistic with improved morale and engagement in language classrooms, as well as reduced language discrimination and validation of students' languages and…

We conducted a meta-analysis to investigate reading-writing relations. Beyond the overall relation, we systematically investigated moderation of the relation as a function of linguistic grain size (word reading and spelling versus reading comprehension and written composition), measurement of reading comprehension (e.g., multiple choice,…

One in seventy-five college students sustains at least one mild traumatic brain injury (mTBI) each academic year. Individuals with TBI, including mTBI, tend to have difficulties with passage comprehension and reading rate, along with reporting reading to be effortful. As reading is fundamental to students' academic success, contributors to reading…

The history of vocabulary research has specified a rich and complex construct, resulting in calls for vocabulary research, assessment, and instruction to take into account the complex problem space of vocabulary. At the intersection of vocabulary theory and assessment modeling, this paper suggests a suite of modeling techniques that model the…

Word frequency has a long history of being considered the most important predictor of word difficulty and has served as a guideline for several aspects of second language vocabulary teaching, learning, and assessment. However, recent empirical research has challenged the supremacy of frequency as a predictor of word difficulty. Accordingly,…
