Research has demonstrated that features of lexical and lexicogrammatical use are important predictors of productive second language (L2) proficiency (e.g. Kyle et al. 2018). While some features of lexical use have been studied with L2s other than English (e.g. Tracy-Ventura 2017), multivariate lexical and lexicogrammatical approaches in these L2s…

The study aimed to explore the evidence of first language (L1) mediation in second language (L2) word associations and the L2 learner-related factors affecting the extent of L1 mediation with the following approaches. First, different from previous research, word association tests (WATs) embraced both receptive and productive word associations in…

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…

Most second language acquisition (SLA) research has documented the processes involved in learning second/foreign languages, with few studies focusing on the durability of attained second language (L2) skills once instructed learners/users are no longer receiving formal instruction. The current study examines the effects of continued exposure and…

Self-regulated learning (SRL) is considered a critical competence for lifelong learning that requires explicit instruction and consistent practice, especially for college students. Despite the abundant intervention studies on the role of SRL in students' academic performance in the Western world, very little is known in China in English as a…

This paper seeks to present the case of successful nativelike proficiency in L7, achieved in adulthood. As a case study of multiple language acquisition processes acquired, both in childhood and adulthood, this study operates in the fields of multilingualism and language acquisition. The author presents her experiences of language acquisition and…

The availability of a first language translation equivalent (i.e., congruency) has repeatedly been shown to influence second-language collocation processing in decontextualized tasks. However, no study to date has examined how L2 speakers process congruent/incongruent collocations on-line in a real-world context. The present study aimed to fill…

This article delves into the ongoing debate surrounding the role of age in second language acquisition, examining developments over the past three decades and highlighting contentious issues. We argue that the commonly held belief in age's pivotal role is frequently contradicted by empirical evidence. Additionally, we examine the agerelated debate…

This dissertation is a quantitative analysis of language proficiencies through the lens of the dynamic model of multilingualism, using survival analysis to evaluate time until thresholds of foreign language proficiency are reached and nonparametric tests (Wilcoxon signed rank and Kruskal-Wallis) to compare proficiencies at distinct time intervals…

Students act according to their beliefs and mindsets. Being aware of such individual differences can help L2 teachers make sound and evidence-based educational decisions. Having said this, the purpose of the current study was to explore the relationship among language mindset, language proficiency, and anxiety through a path analysis in an EFL…

This paper examines English's linguistic imperialism and the resulting widespread use of the language among speakers of various linguistic backgrounds. It challenges the mistaken belief that native speakers (NS) are inherently better at speaking English simply due to their birthplace. Despite the growing number of non-native speakers (NNSs),…

Attaining a high level of proficiency in speaking a second language (L2) is a formidable challenge, particularly in many English as a foreign language (EFL) settings, such as Taiwan. In such environments, students often encounter limited opportunities for English-speaking practice within formal classroom settings due to the prevalence of…

Despite the vast research on test anxiety and test performance since the 1950s, studies on how students' English test anxiety affects their English proficiency test performance in the context of second- and foreign language learning remain few. Therefore, using a quantitative research design, this study explored students' English test anxiety and…

Developing proficiency and intercultural competence are goals promoted by the Modern Language Association and widely shared by postsecondary second language programs across the United States. Although the development of proficiency has been studied extensively in this context, comparatively little is known about how intercultural competence…

Second language (L2) research on input manipulation has focused mainly on increasing the salience of target structures, but presentation formats of L2 input can be another important aspect for manipulation. This study compared the horizontal, vertical, and adjacent formats for presenting the characters, pinyin, and English meaning of L2 Chinese…
