In this study, we assessed metacognition in nonnative language speech perception and production. Spanish novice learners of French identified and produced the French vowel contrast /ø/--/oe/ and, on each trial, rated their confidence in their responses. Participants' confidence in perception predicted their identification accuracy, suggesting that…

Second language implicit learning research has shown that a variety of linguistic features can be acquired without awareness. However, this research overwhelmingly uses comprehension tests to measure implicit learning. It remains unclear whether newly acquired implicit knowledge can also be recruited for production. To address this question, we…

Making adults learn from larger linguistic units can facilitate learning article-noun agreement. Here we ask whether initial exposure to larger units improves learning by increasing the predictive associations between the article and noun. Using an artificial language learning paradigm, we taught 106 Hebrew-speaking participants novel article-noun…

Exploring the underinvestigated area of instruction during study abroad, this article offers a quantitative study of linguistic development among second language university learners of Chinese during a semester in China. A comparison is made between learners following task-based language teaching and a comparison group following a traditional…

The last two decades have seen a significant amount of interest in bilingual language learning and processing. A number of computational models have also been developed to account for bilingualism, with varying degrees of success. In this article, we first briefly introduce the significance of computational approaches to bilingual language…

Recent research on second or additional language (L2) pragmatics instruction in study abroad has incorporated the technique of encouraging students to gather data about pragmatics, for example, by asking members of the host country to complete questionnaires, practice using pragmatic features, or answer questions about pragmatics (e.g., Hernández,…

This study investigated how students' self-reported individual differences predicted second language (L2) spoken discussion task output, an objective behavioral outcome, in the Japanese university English as a Foreign Language (EFL) context. Although numerous psychological theories are used as a rationale for task-based language teaching (TBLT),…

Stern (1983) reminds us of the ethical reasons for doing second language (L2) research. That is, given the considerable human and financial investments that go into language education, the practical activities of teaching "should not exclusively rely on tradition, opinion, or trial-and-error but should be able to draw on rational enquiry,…

This study examines learner deliberations over their discursive plans during second language (L2) instructional tasks, which we call "intersubjectivity negotiation episodes" (INEs). We argue that these provide essential contexts for negotiations over L2 form-meaning mappings, known as "language related episodes" (LREs). Our…

This study demonstrates how conversation analysis can illuminate the interactional practices through which the Present-Attention-Co-construction-Extension (PACE) approach to grammar instruction, which involves a guided, inductive co-construction of grammar rules with learners, is realized in the classroom. The data consist of three whole-class…

Situated within Sociocultural theory (SCT), this article analyzed an existing data set (Toth, 2021a, 2021b, 2021c, available at https://www.iris-database.org) to investigate learners' development through participation in a dialogic approach to grammar instruction called PACE. The target of instruction was the Spanish pronominal clitic…

This article focuses on the role of crosslinguistic patterns with verbs in the mapping of noun phrases/semantic roles to positions in morphosyntax, with a particular focus on second language (L2) development of Spanish "se." The data set derives from high school learners of Spanish in the United States under broadly deductive and…

Multisite research (MSR) offers the key advantages of greater statistical power and external validity via larger and more diverse participant pools. In second language acquisition (SLA) research, recent developments in meta-analysis have created a robust foundation for MSR. Although logistical and financial obstacles can complicate expansion…

The interactionist hypothesis holds that conversational interaction facilitates second language (L2) learning by providing learners opportunities to receive meaningful input, modify their output, and attend to language form. Although research has often explored the efficacy of different types of L2 instruction (deductive or inductive), few studies…

The current study investigated the effects of repetition on the learning of second language (L2) spoken word forms. Japanese university students learning L2 English were randomly assigned to one of three treatment conditions (one, three, and six exposures) and learned 40 words while hearing them and viewing their corresponding pictures. A…
