This article presents a theoretical review of and methodological guidelines for the study of two key notions in second language acquisition research, complexity and difficulty. The term "complexity" has gained considerable currency over the past decades and has taken on a wide range of meanings. We argue for a more restricted…

This study provides an overview of the level of students' cognitive load in learning English in vocational schools. A quantitative descriptive study uses a cross-sectional survey conducted to measure the level of cognitive load of students in learning English in vocational schools. The subjects are 69 respondents who are students from one of the…

This literature review explores the impact of music on tonal language learning, with a focus on Mandarin Chinese. Utilising searches across major databases such as ERIC (EBSCO), ProQuest Central, Google Scholar, and Web of Science from 2005 to 2024, we selected relevant peer-reviewed English-language articles examining music's role in aiding tone…

This study aims to investigate ChatGPT's ability to comprehend input from nonnative speakers, specifically those learning English as a second language, with Japanese speakers serving as the model population. The experiment examines how ChatGPT evaluates the difficulty levels of the Test of English for International Communication (TOEIC), which is…

This study examined the independent effects of working memory (WM) and the interactive effects of WM/L2 proficiency and WM/task complexity on L2 written performance. The study followed a within--between-participant factorial design, with two levels of task complexity as the within-participant variable and L2 proficiency and WM as…

The United States government is perennially in need of employees with proficiency in critical foreign languages to communicate with foreign counterparts and maintain relationships worldwide. In order to fulfill this need, the government devotes significant resources training federal employees to advanced levels of language proficiency through…

The ACTFL Oral Proficiency Interview--computer (OPIc) employs a self-assessment instrument to determine the nature of the speaking prompts to which the test taker will respond and, thus the difficulty of the test. Grounded in research demonstrating varying levels of accuracy in self-assessment among language learners, this study examines the…

The first part of this dissertation conducts a large-scale study comparing general and usage-based indices of syntactic complexity in L2 Mandarin writing samples across a wide range of proficiency levels. To do this, the Tool for the Automated Analysis of Syntactic Sophistication and Complexity (TAASSC; Kyle, 2016) was adapted for Mandarin by…

Reading ability in English is decisive in determining the academic achievement of university students who study the English language, or any other subject in English. Extensive research has been conducted to explore whether ESL/EFL reading problems are language-specific or general reading problems. In this regard, previous research on the…

This study is aimed to identify the effects of task complexity on first language (L1) use and the functions it may serve when two groups of learners of English as a foreign language (EFL) work on collaborative tasks. Twenty-four pairs of Chinese EFL learners from two universities were assigned to a lower-proficiency and a higher-proficiency group,…

Challenges in reading Chinese as a foreign language involve the large proportion of two-character compound words which have complex intra-word morphological structures and scriptal distance between learner's native language (L1) and Chinese as a second or foreign language. This study extended a previous investigation on the processing of Chinese…

The present study investigated the second language processing of grammatical mood in Spanish. Eye-movement data from a group of advanced proficiency second language users revealed nativelike processing with irregular verb stimuli but not with regular verb stimuli. A comparison group of native speakers showed the expected effect with both types of…

This study examined the effects of watching gestures and lip movement on second language (English) listening comprehension. The participants were 30 high and 22 low proficient learners of English. There were six listening tasks combining two variables: modality and difficulty. The modality consisted of three types of assessments: Body (the upper…

Accomplishing a communication task in the real world requires the ability not only to do the task per se but also to manage aspects of the context in which it occurs. For this reason, simulations of target language use contexts have been incorporated into the design of communicative language tests as a way of enhancing the authenticity of…

In order to assess the accuracy and validity of proficiency diagnostic tests in Second Language (L2), specifically regarding the linguistic (orthographic, semantic, syntactic, lexical) and cognitive (verbal reasoning, lexical decision) components for the immigrant population in Portugal, a study of cut-off points of 6 tests was conducted. This…
