This paper represents a summary and discussion of the three studies presented at the morning session of the Fall 2022 JALT Vocabulary SIG. The papers, which were written by Ali Al-Hoorie, Masaki Eguchi, Derek Canning, Stuart McLean, Christopher Nicklin, and Joseph Vitta, represent a range of topics and study designs that are common in recent…

This study investigated phase transitions in EFL students' speech fluency development using a complex dynamic systems perspective. Two students with different proficiency levels were selected from an intact speaking class. These students learned and practiced specific strategies to improve their speech fluency. Phase transitions were analyzed…

This paper problematizes the assessment of speakers' proficiency in endangered language communities. We focus in particular on processes of lexical production and elicitation as proxies for full proficiency assessment. Among linguists, it is standard to assess a speaker's knowledge of specific lexical items in order to set a baseline for further…

Children acquire argument structure through distributional evidence, but how does this interacts with event semantics and existing verb knowledge? The current study compares verb learning in adult speakers of Japanese (where lexical causatives span wider semantic categories) and English (where alternation is more restricted). In the Fully…

Testing is increasingly recognized as a vital part of language revitalization. I demonstrate here that assessment of linguistic knowledge should also be part of the planning process that precedes the creation of a revitalization program. I take as an example Jejueo, the language of Korea's Jeju Island. Whereas previously published work…

The vocabulary research of the 1980s and 1990s brought a breath of fresh air into the language classroom. Teachers in many remote EFL locations had long suspected that vocabulary was their learners' main challenge, but there was little research evidence to confirm this or say what to do about it. Then, suddenly, work by Nation, Laufer, Meara,…

The current study examined the occurrence and benefits of linguistic alignment in two modalities, face-to-face (FTF) and synchronous computer-mediated communication (SCMC), focusing on stranded prepositions in relative clauses. It further examined how learner characteristics (i.e., working memory, language proficiency, previous knowledge of the…

Extending new verbs is important in becoming a productive speaker of a language. Prior results show children have difficulty extending verbs when they have seen events with varied agents. This study further examines the impact of variability on verb learning and asks whether variability interacts with event complexity or differs by language.…

The "Common European Framework of Reference" (CEFR) is the most widespread reference tool for linking language tests, curricula, and national educational standards to levels of foreign language proficiency in Europe. In spite of this, little is known about how the CEFR levels (A1-C2) relate to empirical learner language(s). This article…

This article reviews a selected sample of 70 empirical studies in journal articles and doctoral dissertations on language assessment in China between 2011 and 2018. Following a brief introduction to the history and current state of language assessment in China, the article presents a critical review of language assessment research on six themes…

Whilst the links between learner corpus research (LCR) and Second Language Acquisition (SLA) have long been debated, McEnery et al. (2019. "Corpus Linguistics, Learner Corpora, and SLA: Employing Technology to Analyze Language Use." Annual Review of Applied Linguistics 39: 74-92. doi:10.1017/S0267190519000096) claim that learner corpus…

This article focuses on the acquisition of mood in early complement clauses of European Portuguese (EP). Two semantic features are involved in the EP mood system--epistemicity and veridicality. An elicited production task administered to 80 children aged 4 to 9 showed that, even though children use the subjunctive in [-- epistemic] contexts, the…

This study investigated second language distribution of Chinese connectives by tallying responses on a mini-discourse completion test taken by English-speaking learners with different language learning backgrounds and at different proficiency levels. The results showed that an underuse pattern underlay practically all Chinese connectives as a…

Is there an ideal time window for language acquisition after which nativelike representation and processing are unattainable? Although this question has been heavily debated, no consensus has been reached. Here, we present evidence for a sensitive period in language development and show that it is specific to grammar. We conducted a masked priming…

This article proposes that second language learners can use indirect positive evidence (IPE) to acquire a phonological grammar that is a subset of their L1 grammar. IPE is evidence from errors in the learner's L1 made by native speakers of the learner's L2. It has been assumed that subset grammars may be acquired using direct or indirect negative…
