Eta-squared (?[superscript 2]) and partial eta-squared (?[subscript p][superscript 2]) are effect sizes that express the amount of variance accounted for by one or more independent variables. These indices are generally used in conjunction with ANOVA, the most commonly used statistical test in second language (L2) research (Plonsky, 2013).…

The last 15 years has seen a tremendous growth in research on structural priming among second language (L2) speakers. Structural priming is the phenomenon whereby speakers are more likely to repeat a structure they have recently heard or produced. Research on L2 structural priming speaks to key issues regarding the underlying linguistic and…

The construct of awareness plays a pivotal role in several big debates in the field of second language acquisition. It lies at the heart of discussions about the (im)possibility of learning without awareness, or conversely, whether some degree of awareness is a requirement for learning to take place. In this study, I propose a research agenda to…

Although increasing literature has suggested that emotion-label words (e.g., anger, delight) and emotion-laden words (e.g., thief, bride) were processed differently in native language (L1), there was a lack of neuroimaging evidence showing such differences in second language (L2). The current study compared the cortical responses to emotion-label…

The extensive literature on subject expression in Spanish makes for rich comparisons between generative (formal) and usage-based (functional) approaches to language acquisition. This article explores how the problem of subject expression has been conceptualized within each research tradition, as well as unanswered questions that both approaches…

Previous studies in the acquisition of clitic se in Spanish have focused on the syntactic processes needed to perform detransitivization. However, current approaches on event structure reveal that "se" encodes aspectual information which is crucial for its acquisition. We examine the use, intuition and interpretation of the aspectual…

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…

This study reports on a self-paced reading experiment in which native and non-native speakers of English read sentences designed to evaluate the predictions of usage-based and rule-based approaches to second language acquisition (SLA). Critical stimuli were four-word sequences embedded into sentences in which phrase frequency and grammaticality…

This study investigated French and Spanish EFL (English as a foreign language) learners' preferred use of three-word lexical bundles with discourse or stance-oriented function with a view to exploring the role of first language (L1) frequency effects in foreign language acquisition. Word combinations were extracted from learner performance data…

This article presents a generative analysis of the acquisition of formulaic language as an alternative to current usage-based proposals. One influential view of the role of formulaic expressions in second language (L2) development is that they are a bootstrapping mechanism into the L2 grammar; an initial repertoire of constructions allows for…

A study was conducted to examine production variability in American Sign Language (ASL) in order to gain insight into the development of motor control in a language produced in another modality. Production variability was characterized through the spatiotemporal index (STI), which represents production stability in whole utterances and is a…

The present study examines and compares the extent to which advanced L2 learners of Spanish and Spanish heritage speakers acquire the syntactic and semantic properties that regulate the grammatical representation of double complementizer questions in Spanish, a CP-related structure not present in English. Results from an aural sentence completion…

The present study is an attempt to empirically test and compare the results of three methods of word association (WA) analysis. Two of the methods--namely, associative commonality and nativelikeness, and lexico-syntactic patterns of associative organization--have been traditionally used in both first language (L1) and second language (L2)…

The present article focuses on data collection through web questionnaires, as opposed to the traditional pen-and-paper method for research in second language acquisition and bilingualism. It is argued that web questionnaires, which have been used quite widely in psychology, have the advantage of reaching out to a larger and more diverse pool of…

The present article provides an exploration of ultimate attainment in second language (L2) and its limitations. It is argued that the question of maturational constraints can best be investigated when the reference population is bilingual and exposed on a regular basis to varieties of their first language (L1) that show cross-linguistic influence.…
