The effects of learner- and task-related variables on second language (L2) writing syntactic complexity (SC) have been extensively investigated. However, previous research has rarely assessed the reliability of computational tools for analyzing the SC of L2 spoken production, and we know less about the effects of such variables on L2 speaking SC.…

This study proposed a set of measures for assessing noun phrase (NP) complexity in second language (L2) Chinese writing and compared the predictive power of these measures for L2 Chinese writing quality to that of a set of syntactic complexity measures based on the topic-comment unit (TC-unit). Our data consisted of 101 narratives written by…

Linguistic complexity serves as an important measure of second language (L2) writing development. Complexity indices, however, rarely feature in the studies of learner languages other than English. Additionally, L2 writing studies have been criticized for the lack of consistency in defining proficiency. The current study addresses these gaps by…

Focus on form (FonF) studies have predominantly addressed its effectiveness in improving learners' syntactic, lexical, orthographic, and phonological knowledge. Extending the scope of this line of research to formulaic FonF practices, this study investigates the relative effectiveness of incidental FonF targeting formulaic versus nonformulaic…

Learner corpus studies using syntactic complexity as a construct for characterizing learner proficiency have found that higher proficiency permits learners to produce more complex syntactic structures. However, the majority of previous studies have focused on writing, almost exclusively with adult second language (L2) learners. Given the…

We examined the role of modality in learning second language (L2) grammar and forming implicit (unconscious) and explicit (conscious) knowledge. To this end, we isolated the effects of the physical medium of input (i.e., aural or visual) from those of the presentation method (i.e., word-by-word or simultaneous). We also explored the role of test…

Research has painted a pessimistic picture of students' second language (L2) writing skills in secondary education. One innovative tool that may help students foster their L2 proficiency, including writing ability, is in-class debate. Debate is commonly associated with oral communication and argumentation skills. However, debate may also offer…

This study investigates the role of prosodic cues and explicit information (EI) in the acquisition of German accusative case markers. We compared 4 groups of 3rd-semester learners (low intermediate level) who completed 1 of 4 Processing Instruction (PI) treatments that manipulated the presence or absence of EI and focused prosody. The results…

The present study explores the independent and interactive effects of task complexity and task modality on linguistic dimensions of second language (L2) performance and investigates how these effects are modulated by individual differences in working memory capacity. Thirty-two intermediate learners of L2 Spanish completed less and more complex…

This study explores the teaching of second language (L2) Spanish sociopragmatics through concept-based pragmatics instruction (van Compernolle, 2014). The concepts of self-presentation, social distance, and power were the focus of a pedagogical enrichment program in 2 sections of a beginning-level Spanish class at a northeastern U.S. university.…

This study introduces an approach to providing corrective feedback to L2 learners termed analogy-based corrective feedback that is motivated by analogical learning theories and syntactic alignment in dialogue. Learners are presented with a structurally similar synonymous version of their output where the erroneous form is corrected, and they must…

This study investigated whether second language (L2) speakers' morphosyntactic pattern learning was predicted by their statistical learning and working memory abilities. Across three experiments, Thai English as a Foreign Language (EFL) university students (N = 140) were exposed to either the transitive construction in Esperanto (e.g., "tauro…

An experiment investigated adult language learners' ability to develop fully integrated cognitive representations of a difficult second language (L2) morphosyntactic feature: the Korean honorific verbal affix "(u)si." Native speaker (NS) and nonnative speaker (NNS) latencies during a word-by-word self-paced reading comprehension task…

This study tracks the development of syntactic complexity in the writing of two beginning German as a second language learners with English as a first language over four semesters of collegiate language study by using developmental profiling techniques applied to an annotated learner corpus. The focus of the investigation is on individual…

Motivated by cognitive-interactionist frameworks for task-based learning, this study explores whether task complexity affects the extent to which learners focus on form-meaning connections during task-based work in a classroom setting, and whether this relationship is modulated by 3 individual difference factors--linguistic self-confidence,…
