This study examined an integrated process model of second language motivation based on the framework of self-determination theory (SDT). Specifically, this research investigated the extent to which satisfying basic psychological needs (BPN) are related to SDT orientations and, in turn, to the effort expended and how these factors relate collectively to vocabulary knowledge. Revised scales assessing students’ BPN (the Basic Psychological Needs of Second Language Scale) and SDT orientations (the Self-Determination Theory of Second Language Scale) were considered and tested using a higher-order confirmatory factor analysis solution. The results of the structural model showed that BPN were only directly related to vocabulary knowledge, which indicated their direct importance for the attainment of the vocabulary. No other indirect effects through SDT orientations or effort were identified. Nonetheless, SDT orientations were both directly and indirectly linked to vocabulary knowledge over and above the role of expended effort. The results elucidated motivational pathways that yielded pedagogical implications for language learning.

This study offers methodological synergy in the examination of factorial structure in second language (L2) research. It illustrates the effectiveness and flexibility of the recently developed exploratory structural equation modeling (ESEM) method, which integrates the advantages of exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) into one complete measurement model. Two sets of data were collected using the L2 Passion Scale, which measures a dualistic model of passion. Study 1 participants were 220 L2 students. A comparison was made between the CFA and the ESEM models. The results demonstrated the superiority of the ESEM method relative to CFA in terms of better goodness-of-fit indices and realistic correlated factors. These results were replicated in another sample of 272 L2 students, providing support for the predictive validity using a structural ESEM model. Guidelines are provided and Mplus syntax files (codes) are included to help analysts apply the methods. We also make the data available publicly. Overall, this research demonstrated the usefulness of ESEM for examining the construct, discriminant, and convergent validity of L2 scales over CFA.

The extent to which individual differences in cognitive abilities affect the relationship among task complexity, attention to form, and second language development has been addressed only minimally in the cognition hypothesis literature. The present study explores how reasoning demands in tasks and working memory (WM) capacity predict learners’ ability to notice English question structures provided in the form of recasts and how this contributes to subsequent development of English question formation. Eighty-one nonnative speakers of English completed three interactive tasks with a native speaker interlocutor, one WM task, and three oral production tests. Prior to the first interactive task, participants were randomly assigned to a task group (simple or complex). During task performance, all learners were provided with recasts targeting errors in question formation. The results showed that learners’ cognitive processes during tasks were in line with the cognitive demands of the tasks, at two complexity levels. The findings suggest that WM was the only significant predictor of the amount of noticing of recasts as well as of learners’ question development. With regard to interaction effects between WM and task complexity, high WM learners who carried out a complex version of the tasks benefitted the most from task-based interaction.

Typological markedness has been suggested as a possible explanation or a means of predicting the development of Interlanguage (IL) syntax (Eckman, 1977; Hyltenstam, 1978, 1984; Rutherford, 1982). More specifically, the Accessibility Hierarchy (AH) (Keenan & Comrie, 1977, 1979) has been used to predict the acquisitional order of relative clauses in a second language (Hyltenstam, 1984). No research, however, has been conducted to investigate the possible influence of learning context on relative clause (RC) formation. In this study, English relative clauses were elicited from two groups of Italian learners. The first group was composed of 48 formal learners and the second group of 38 informal learners. It was hypothesized that the order as predicted by the AH would be yielded by both groups with the formal group's IL exhibiting more marked structures than the informal group's. The type of discourse—planned versus unplanned—to which learners were mostly exposed was thought to have an effect on the level of linguistic elaboration achieved.

This study explored the usefulness of dual-task methodology, self-ratings, and expert judgments in assessing task-generated cognitive demands as a way to provide validity evidence for manipulations of task complexity. The participants were 96 students and 61 English as a second language (ESL) teachers. The students, 48 English native speakers and 48 ESL speakers, carried out simple and complex versions of three oral tasks—a picture narrative, a map task, and a decision-making task. Half of the students completed the tasks under a dual-task condition. The remaining half performed the tasks under a single-task condition without a secondary task. Participants in the single condition were asked to rate their perceived mental effort and task difficulty. The ESL teachers provided expert judgments of anticipated mental effort and task difficulty along with explanations for their ratings via an online questionnaire. As predicted, the more complex task versions were found and judged to pose greater cognitive effort on most measures.

Research investigating incidental vocabulary learning through listening to songs has primarily relied on participant’s self-report surveys on listening behaviors and its relationship with their vocabulary knowledge (Kuppens, 2010). Only one experimental study has investigated vocabulary learning gains from listening to songs (Medina, 1993). From the results, the researcher concluded that learning does occur from listening to songs. However, the learning gains were not provided. The present study investigated incidental learning of three vocabulary knowledge dimensions (spoken-form recognition, form-meaning connection, and collocation recognition) through listening to two songs. The effects of repeated listening to a single song (one, three, or five times) and the relationship between frequency of exposure to the targeted vocabulary items and learning gains were also explored. The results indicated that (a) listening to songs contributed to vocabulary learning, (b) repeated listening had a positive effect on vocabulary gains, and (c) frequency of exposure positively affected learning gains.

This study examined contributions of lexical factors to native-speaking raters’ assessments of comprehensibility (ease of understanding) of second language (L2) speech. Extemporaneous oral narratives elicited from 40 French speakers of L2 English were transcribed and evaluated for comprehensibility by 10 raters. Subsequently, the samples were analyzed for 12 lexical variables targeting diverse domains of lexical usage (appropriateness, fluency, variation, sophistication, abstractness, and sense relations). For beginner-to-intermediate speakers, comprehensibility was related to basic uses of L2 vocabulary (fluent and accurate use of concrete words). For intermediate-to-advanced speakers, comprehensibility was linked to sophisticated uses of L2 lexis (morphologically accurate use of complex, less familiar, polysemous words). These findings, which highlight complex associations between lexical variables and L2 comprehensibility, suggest that improving comprehensibility requires attention to multiple lexical domains of L2 performance.

Within the field of SLA, the incidence of nativelikeness in second language (L2) speakers has typically been explained as a function of age of acquisition. An alternative interpretation, however, is that L2 learners do not attain nativelike proficiency because of first language (L1) maintenance. This interpretation has nevertheless remained mostly theoretical due to the lack of empirical evidence. This study sets out to address the role of L1 proficiency in L2 ultimate attainment by examining L1 and L2 proficiency in 30 early L1 Spanish–L2 Swedish bilinguals. Language proficiency was assessed through grammaticality judgment tests and cloze tests, and additional data on language aptitude were collected through the Swansea Language Aptitude Test (v.2.0; Meara, Milton, & Lorenzo-Dus, 2002). The results showed positive correlations between nativelike L1 and L2 behavior. Additionally, it was found that language aptitude was positively correlated with nativelike L1 and L2 performance. In view of these findings, it is suggested that (a) L1 maintenance does not hamper L2 nativelikeness and (b) language aptitude is an important factor for bilingual ultimate attainment.

John Schumann and colleagues (Jacobs, 1988; Jacobs & Schumann, 1992; Pulvermüller & Schumann, 1994; Schumann, 1990a, 1990b) have argued for a neurobiological perspective on language acquisition, one that denies a role for a specifically linguistic mental module of the sort proposed by, for example, Chomsky (e.g., 1986). In this paper, we challenge this perspective by offering evidence that such a mental module must be involved in the acquisition of grammatical competence.

The L2 lexical proficiency of 69 grade 6 French immersion students is compared with that of 22 native French-speaking peers, based on verb use in five written compositions. Measures of lexical error, variety, specificity, and sophistication show clear differences between the two groups. The learners' patterns of use of verb vocabulary are considered in relation to frequency and utility in French, the degree of congruence between L2 and L1, and the morpho-syntactic complexity of some specific types of French verbs. Results are further discussed in relation to observational data from grade 6 immersion classrooms.

The major purposes of this article are to briefly describe the rationale and history of development of the “proficiency-based” testing movement in the United States, its current status, and areas in which additional research and development work are recommended to enhance both the psychometric validity and practical value of this approach.

This study explored the roles of exposure frequency, aural enhancement (AE) of input, and individual differences in working memory (WM) during L2 incidental vocabulary learning while reading. Eighty intermediate-level English learners were divided into four treatment groups, and given reading tasks with target words embedded two or four times. Listening while reading was controlled, as well as duration of exposure to new words through timed reading tasks, and comprehension questions helped to ensure a focus on meaning. Surprise posttests assessed initial form recognition and form-meaning connections. Proficiency and WM measures were administered, with English proficiency used as a covariate. Results indicated that measurable learning occurred at the two-exposure level for new words, both in form recognition and form-meaning connections. Frequency effects held from two to four exposures across AE and non-AE conditions, but were influenced by AE on the form-meaning outcome. This indicated support for simultaneous input modalities facilitating deeper processing and better learning outcomes. WM outcomes correlated with vocabulary outcomes for form recognition, and an aptitude by treatment interaction was found for form recognition.

This article provides a comprehensive synthesis of research on language attrition to date, with a view to establishing a theoretically sound basis for future research in the domain of second language (L2) attrition. We identify the variables that must be tracked in populations who experience language loss, and we develop a general model for the assessment of the processes involved. This critical review suggests that future research in this domain should establish baselines for attainment against which to measure attrition, and that learners must be compared to themselves in longitudinal designs that involve periodic assessment of both linguistic and extralinguistic factors. In the proposed model, populations are defined as sets of variables, which are subject to change following shifts in discrete time periods in the general process of acquisition and attrition. A working model is elaborated for the assessment of L2 attrition and retention, which, we hope, might encourage additional work in this area.

This study examined the linguistic dimensions of comprehensibility and perceived fluency in the context of L2 argumentative speech elicited from 40 Japanese-speaking learners of English. Their speaking performance was judged by 10 inexperienced native speakers of English for comprehensibility and perceived fluency, and was also objectively analyzed in terms of complexity, accuracy, and fluency as well as pronunciation and discourse features. The results showed that comprehensibility and fluency judgments strongly correlated with each other and that native listeners were significantly more severe when they judged fluency. Furthermore, multiple regression analyses revealed that both constructs were commonly associated with a set of underlying linguistic dimensions (grammatical accuracy, breakdown fluency, and pronunciation). However, comprehensibility was best predicted by articulation rate (speed fluency) whereas perceived fluency was most strongly associated with the frequency of mid-clause pauses (breakdown fluency).

This article surveys the development of second language acquisition research in the area of tense and aspect. Research in the area has grown from the incidental investigation of tense-aspect morphology as part of the morpheme-order studies to investigations of the construction of interlanguage temporal semantics. Going beyond verbal morphology, many studies investigate a full range of temporal expression, including the use of pragmatic and lexical means. Much recent research also draws on theories of inherent, or lexical, aspect. An emphasis on the relation of form and meaning characterizes both the form-oriented approach and the semantic-oriented approach, the competing research paradigms that currently guide our work. The increase in scholarly activity in this domain of second language acquisition, as reflected not only in the number of studies undertaken but in the number of target languages investigated, bodes well for the understanding of temporality in second language.

Theoretical claims about the benefits of corrective feedback have been largely premised on learners’ noticing of feedback (e.g., Gass & Mackey, 2006; Long, 1996; Schmidt, 1990, 1995; Swain, 1995), and findings have demonstrated that both the feedback target (Mackey, Gass, & McDonough, 2000) and the mode of provision (Lai & Zhao, 2006) can affect learners’ accurate perception of feedback. The current study extended this research by investigating learners’ perception and use of feedback provided in task-based interaction in both computer-mediated (CMC) and face-to-face (FTF) modes. Utilizing stimulated recall, the study examined if 24 intermediate-level learners of Spanish as a foreign language accurately noticed feedback as feedback, if they noticed the feedback target, and if the environment in which they interacted (CMC vs. FTF) made a difference in their accuracy. The study also investigated if modality affected opportunities for modified output immediately following feedback and if learners used those opportunities differently according to mode. Results demonstrated that, overall, learners did notice feedback as feedback in both modes. Contrary to expectations, there were no statistical differences between modes in feedback perception accuracy. Significant differences were found, however, in learners’ opportunities for and use of feedback depending on the interaction environment and the type of error being addressed.

This article describes how information gap tasks can be designed as instruments for data collection and analysis and as treatments in interaction research. The development of such tasks is illustrated and data are presented on their role in drawing learners' attention to second language (L2) forms that are difficult to notice through classroom discussion alone. Because the tasks presented here are closed-ended and precision oriented and require the exchange of uniquely held information, they promote modified interaction among participants and orient their attention to form, function, and meaning. These processes can be observed by the researcher during task implementation. Thus, the tasks reduce researcher dependence on externally applied treatments and analytical instruments not integral to the interaction itself. To illustrate this methodology in use, we report on a study in which six pairs of intermediate-level English L2 learners carried out three types of information gap tasks in their classrooms. They first read passages on familiar topics, whose sentences contained L2 forms that were low in salience and difficult to master but developmentally appropriate. To complete the tasks, the learners were required to identify, recall, and compare the forms, their functions, and their meanings. Data revealed close relationships among learners' attentional processes, their recall of form, function, and meaning, and the interactional processes that supported their efforts.In carrying out the design and implementation of the tasks in this article, we have worked most closely with Kristine Billmyer and MaryAnn Julian, and also Jin Ahn, Marni Baker-Stein, Mara Blake-Ward, Lyn Buchheit, Junko Hondo, Sharon Nicolary, and Jack Sullivan.

In this paper we address the need for replication studies in the field of second language acquisition and discuss the problems surrounding standards of reporting research. A particular focus is on the level of detail necessary for replication to take place. The lack of uniform standards is noted with specific examples of problematic reporting taken from descriptions of second language learners' proficiency levels and measures of linguistic accuracy in second language writing research. We propose ways that we believe will lead to more thorough reporting of research and that will therefore allow others to engage in replication.

In this article, the current state of second language classroom-oriented research is subjected to critical review. The article begins by providing a brief overview of aims and issues in classroom-oriented research, before focusing more specifically on methodological issues in research. The review is based on an analysis of 50 empirical investigations of teaching and learning. These studies are analyzed in terms of their rationale, the environment in which they were carried out, the design and method of data collection, and the type of analysis carried out on the data. In the final part of the article, the implications of the study for future classroom research are presented and discussed.
