The purpose of this study is to equate and further validate three forms of the vocabulary size test (VST) created by Aizawa and Mochizuki (2010). These three forms, VST 1, 2, and 3, were administered to a cohort of 189 high school students ranging in age from 16 to 18 in April of their 1st, 2nd, and 3rd year of high school. Although these…

Toddlerhood is marked by advances in several lexico-semantic skills, including improvements in the size and structure of the lexicon and increased efficiency in lexical processing. This project seeks to delineate how early changes in vocabulary size and vocabulary structure support lexical processing (Experiment 1), and how these three skills…

Based on 312 samples, this study investigated the relationship between two dimensions of L2 vocabulary knowledge (VK) and listening comprehension (LC) by comparing written and oral vocabulary measurements and further examined the mediating effect of L2 vocabulary fluency (VF) by using Bootstrapping and Monte Carlo Method. Results show that: (1)…

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…

The present study primarily aims to investigate the relationship between Pakistani students' receptive vocabulary growth and their reading development at two different points: at the beginning and the end of English course. The standardized vocabulary size test (VST) and reading comprehension test (TOEFL) were administered to 123 first year…

This study documented the standardized tests and informal assessment techniques that school-based speech-language pathologists (SLPs) reported as most helpful for identifying vocabulary deficits and for monitoring progress. Speech-language pathologists (N = 142) working in U.S. public school settings completed an online survey that included…

This study investigates how learners use a freely available web-based multimodal language learning environment based on videos and newspaper articles with corresponding exercises and learning support in the form of help options, "NedBox," for learning L2 Dutch. In order to measure learners' use, a combination of eye movement and screen…

This study examined the effects of three subtitle conditions on English vocabulary learning, form recognition and meaning recall, from TED Talks videos while controlling for vocabulary size and initial knowledge of the target words. The participants, 105 Libyan students (16 males and 89 females) at intermediate English proficiency level, were…

Many words are associated with more than a single meaning. Words are sometimes "ambiguous," applying to unrelated meanings, but the majority of frequent words are "polysemous" in that they apply to multiple "related" meanings. In a preregistered design that included 2 tasks, we tested adults' and 4.5- to 7-year-old…

Although retrieval of lexical forms is a prerequisite for language production, research of L2 vocabulary learning has focused much more on meanings and form-meaning mappings than on development of detailed, accessible mental representations of forms. This is particularly true with respect to multi-word items (MWIs). We report an experimental study…

This study investigates the relationship between depth of academic vocabulary knowledge and academic success among Saudi English-as-a-foreign-language university students. Fifty fourth-year university students majoring in English completed a vocabulary depth test, the Word Associates Test (WAT), based on the Academic Word List (AWL). Then,…

This study investigated the effects of processing three types of texts, namely expository texts, narrative texts, and a combination of both known as twin texts, on incidental vocabulary acquisition and retention in L2 learners. College freshmen (N = 109), who were lower to upper intermediate learners of English, were assigned into a control group…

The current study was planned to find out if the use of blended learning as a combination of face-to-face instruction and mobile-assisted language learning using WhatsApp contributed to the vocabulary learning and autonomy of Iranian EFL learners compared to the traditional method. To assess their English skills, PET was given to 80 homogenous…

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,…

The study's objective is to examine the effects of Blended Mobile Learning (BML) on the vocabulary development of EFL preparatory students and their views of BML. As a mixed method study, it was conducted with 40 preparatory students at a state university in Turkey. While the control group studied vocabulary by reading texts only in the classroom…
