Background: Core lexicon (CL) analysis is a time efficient and possibly reliable measure that captures discourse production abilities. For people with aphasia, CL scores have demonstrated correlations with aphasia severity, as well as other discourse and linguistic measures. It was also found to be clinician-friendly and clinically sensitive…

Although lexical diversity is often used as a measure of productive proficiency (e.g., as an aspect of lexical complexity) in SLA studies involving oral tasks, relatively little research has been conducted to support the reliability and/or validity of these indices in spoken contexts. Furthermore, SLA researchers commonly use indices of lexical…

Remote association, the ability to form new relations between independent elements, was assessed using the Remote Associates Test (RAT). The Chinese RAT (CRAT) includes the Chinese radical RAT (CRRAT), Chinese word RAT (CWRAT), and Chinese compound RAT (CCRAT). Behavioral research indicates that an individual's performance on the CRAT reflects…

The purpose of the current dissertation is to map the relationships between first language (L1), writing quality, and syntactic complexity, accuracy, lexical complexity, and fluency (CALF) in second language (L2) writing. CALF are characteristics of language production that have been of significant interest in L2 writing research for the past few…

The study examined the impact of a first language's summarizing skill and second language vocabulary size on summary performances in a second language. A total of 40 English as a Foreign Language (EFL) learners from a Japanese university with a mixed level of English language proficiency were asked to write a summary in English (i.e., their…

Many overseas students in Higher Education in the UK struggle to understand the compulsory texts for their course, and obtain lower scores for their modules than their monolingual peers. While the existence of this achievement gap is well established in the literature, little is known about the ways in which overseas students in HE with limited…

Efforts to improve classroom language practices and children's language learning, as a means of supporting reading comprehension, may depend on teachers' knowledge about language structures and language development. To date, however, educational researchers and teacher educators have little understanding about teachers' knowledge about oral…

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…

The sentence repetition (SR) test is considered as a promising diagnostic tool for detecting language proficiency in monolingual learners, but less is known about its potential to identify dual language learners' (DLLs) linguistic proficiency. Considering that challenges with language learning, such as developmental language disorders (DLDs), is…

Research with school-age readers suggests that the contributions of reading and language skills vary across reading comprehension assessments and proficiency levels. With a sample of 168 struggling adult readers, we estimated the explanatory effects of decoding, oral vocabulary, listening comprehension, fluency, background knowledge, and…

The current study sought to examine the validity of a General English Achievement Test (GEAT), administered to university students in the fall semester of 2018-2019 academic year, by hybridizing differential information (DIF) and differential distractor function (DDF) analytical models. Using a purposive sampling method, from the target population…

Research with school-age readers suggests that the contributions of reading and language skills vary across reading comprehension assessments and proficiency levels. With a sample of 168 struggling adult readers, we estimated the explanatory effects of decoding, oral vocabulary, listening comprehension, fluency, background knowledge, and…

The present study aims to reveal the effects of test type, pronunciation and proficiency levels of the students on speaking test scores. A total of 147 Turkish EFL students consisting of 38 beginner, 36 elementary, 37 pre-intermediate and 36 intermediate levels participated in the study. Presentation as planned, and paired speaking test as…

This study aims at investigating the relationship between student's second language lexical fluency and their C-test performance. Using cluster sampling procedure,75 undergraduate students of Engineering and Basic Sciences studying general English at Shahrood University of Technology were randomly selected to participate in this study. Controlled…

Purpose: We examined receptive verb knowledge in 22- to 24-month-old toddlers with a dynamic video eye-tracking test. The primary goal of the study was to examine the utility of eye-gaze measures that are commonly used to study noun knowledge for studying verb knowledge. Method: Forty typically developing toddlers participated. They viewed 2…
