Abundant research has indicated fluency features as meaningful predictors of second language proficiency. However, the extent to which different fluency dimensions and features can predict proficiency remains underexplored. This meta-analysis employed a multilevel modeling approach to synthesize fluency-proficiency relationships from 71 empirical…

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…

This article examines how tertiary language learners of German engaged with the novel "Blutbuch" (2022) by Swiss author Kim de l'Horizon. Celebrated as the first nonbinary novel in German literature, excerpts of this autofictional text were taught in a 3-week unit, which was part of a semester-long German course targeted at university…

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 study examined second language (L2) learning difficulty of 13 Chinese grammatical constructions on the basis of teachers' perceptions and associated the L2 learning difficulty of Chinese grammatical constructions with teacher-perceived learner grammatical competence and with the instructional levels. A total of 77 experienced teachers were…

This study investigates the strategies employed by Thai learners of Chinese as a second language (L2) to comprehend metaphors, focusing on how language proficiency shapes their approach. Using a mixed-methods design, 29 participants--ranging from beginner to advanced levels--completed metaphor interpretation tasks and provided self-reports on…

Scores of different language tests intended for similar purposes (e.g., admission to higher education) are used to determine candidates' language proficiency and readiness for a chosen domain. To be fair to all students irrespective of the test they took, score requirements should be comparable. Score concordance tables provide an empirical basis…

Although researchers have found strong relationships between first language (L1) skills and second language (L2) anxiety, less is known about how L1 skills in primary school impact L2 anxiety years after L1 has been acquired. Previous research lacked evidence for the mediating role of L2 aptitude and L2 achievement in the relationship. This study…

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…

The measurement of second language (L2) productive lexical proficiency has driven a great deal of research over the past two decades. Research has indicated that more proficient speakers and writers tend to use a wider range of words and that more proficient writers tend to use words that are more sophisticated (less frequent in reference…
