The current study reports on a meta-analysis of the relative effectiveness of interaction in synchronous computer-mediated communication (SCMC) and face-to-face (FTF) contexts. The primary studies included in the analysis were journal articles and dissertations completed between 1990 and 2012 (k = 14). Results demonstrate that interaction in SCMC and FTF had a significant impact on second language (L2) development, providing further support for previous research demonstrating the efficacy of interaction in both communication modes (e.g., Mackey & Goo, 2007; Pellettieri, 2000; Smith, 2004, 2005). There was also a small advantage for interaction in SCMC on measures of overall L2 learning outcomes, with additional analyses indicating a small advantage for SCMC interaction on productive and written measures and a small advantage for FTF interaction on receptive and oral learning outcomes. Interestingly, there were no significant differences between SCMC and FTF, suggesting the mode of communication has no statistically significant impact on the positive developmental benefits associated with interaction.

Untrained native English listeners assigned foreign accent scores to sentence and narrative utterances that had been rendered unintelligible through low-pass filtering. Utterances produced by native English talkers were assigned consistently higher ratings than those produced by Mandarin-speaking learners of English, even when the listeners were unfamiliar with the content. Because these filtered speech stimuli contained very little of what could be considered segmental information, the results suggest that untrained listeners can identify foreign-accented speech on the basis of nonsegmental information alone, whether they are presented with material of known or of unknown content. Acoustical analyses of the stimuli suggested that differences in speaking rates, intonation patterns, and timing may have played a role in the listeners' assessments, although the cues to foreign-accentedness may have varied from talker to talker and from utterance to utterance. Surprisingly, no relationship was observed between the ratings of the filtered and unfiltered versions of the nonnative stimuli.

Although it is well known that many second language (L2) learners have trouble using articles “properly,” the primary causes of their difficulties remain unclear. This study addresses this problem by examining the metalinguistic knowledge of the English article system that learners employ when selecting articles in a given situation. By doing this, the present study attempts to better understand the process of “making sense” of the English article system by learners who are at different stages in their interlanguage development. Eighty Japanese college students with varying levels of English proficiency participated in this study. Immediately after completing a fill-in-the-article test, a structured interview was conducted to investigate the reasons for their article choices. The quantitative and qualitative analyses reveal a number of conceptual differences with regard to their considerations of the hearer's knowledge, specific reference, and countability, which may account for learners' errors in article use across different proficiency groups.

This study examines the relationship between the repetition of oral monologue tasks and immediate gains in L2 fluency. It considers the effect of aural-oral task repetition on speech rate, frequency of clause-final and midclause filled pauses, and overt self-repairs across different task types and proficiency levels and relates these findings to specific stages of L2 speech production (conceptualization, formulation, and monitoring). Thirty-two Japanese learners of English sampled at three levels of proficiency completed three oral communication tasks (instruction, narration, and opinion) six times. Results revealed that immediate aural-oral same task repetition was related to gains in oral fluency regardless of proficiency level or task type. Overall gains in speech rate were the largest across the first three performances of each task type but continued until the fifth performance. More specifically, however, clause-final pauses decreased until the second performance, midclause pauses decreased up to the fourth, and self-repairs decreased only after the fourth performance, indicating that task repetition may have been differentially related to specific stages in the speech production process.

This paper takes the papers in this special collection as a starting point and raises issues concerning key terms, with particular emphasis on incidental. It is argued that there is no clear way to show that a word has been learned incidentally, if one means that specific attention is not drawn to that word either by some external force or by the learner. I further argue that, to understand vocabulary learning, linguists cannot limit the investigation to word meaning. Essential to a study of the lexicon is the study of syntax—in particular, the incorporation of syntactic subcategorizations. Taking all of these factors into account, a more nuanced approach to the study of incidental vocabulary learning is needed.

Two hypotheses regarding the distribution of emergent tense-aspect morphology in SLA have been proposed: the aspect hypothesis, which claims the distribution of interlanguage verbal morphology is determined by lexical aspectual class, and the discourse hypothesis, which claims it is determined by narrative structure. Recent studies have tested and supported both hypotheses individually. This study expands the investigation to include an analysis of both narrative structure and lexical aspectual class in a single corpus comprising 74 narratives (37 oral and written pairs) produced by adult learners of English as a second language at various proficiency levels. The results suggest that both hypotheses are necessary to account for the distribution of verbal morphology in interlanguage.

Building on the control-value theory, the present study examined the independent and joint predictive effects of three emotions—enjoyment, anxiety, and boredom—on L2 achievement over time. The participants of the study were a group of junior secondary English learners in rural China, a population that has hitherto never featured in L2 learning research. Questionnaire data and achievement data were collected at four different time points (Time 1–Time 4: T1–T4) from a large sample of 954 learners. Structural equation modeling results show that: (a) the three emotions at T1 predicted English achievement at T2 (one week after T1) and T3 (five weeks after T1) independently, while only enjoyment predicted achievement at T4 (nine weeks after T1); (b) when combined, enjoyment was the strongest and most enduring predictor across T2–T4, followed by anxiety predicting achievement at T2–T3 negatively, while boredom completely lost its predictive power across T2–T4.

This paper discusses the simplification of forms ending in obstruents by native speakers of Mandarin, in particular two effects that are not obviously motivated by either the native- or the target-language grammars: a tendency to devoice final voiced obstruents and a tendency to maximize the number of bisyllabic forms in the output. These patterns are accounted for within Optimality Theory, which describes a grammar as a set of universal, ranked constraints. It is argued that the devoicing and bisyllabicity effects result from universal markedness constraints that are present in all grammars but that are masked in the learner's native-language grammar by the effects of higher ranking constraints.

A major requirement for theory development in L2 vocabulary acquisition is an adequate model of L2 lexical organization and processing. At present, there is no widely accepted model of this kind, but recent research has demonstrated the potential usefulness of Levelt's (1989, 1993) L1 speech processing model (de Bot & Schreuder, 1993; Green, 1993; Poulisse, 1993). This paper explores the relevance of the model as adapted for L2 lexical processing of written texts, with particular attention to its mental lexicon components (concepts, lemmas, and lexemes) and organization. The model is first discussed in terms of its relevance to L2 lexical access, retrieval, and acquisition processes. Findings of an introspective L2 vocabulary study follow, detailing how university ESL learners reported dealing with unfamiliar words while carrying out L2 reading tasks. The information provided on their lexical inferencing strategy and varied knowledge sources used in the process provide support for the lexical components and organization proposed by Levelt. It is argued in this paper that the process of inferring the features of unknown words in a reading passage can be described in terms of lemma construction, as defined in the model.

Subjective theories are very complex cognitive structures: they are highly individual, relatively stable, and relatively enduring. Examples are learners' and teachers' general beliefs about language, and about learning and teaching. In psychology and educational science it has been demonstrated that subjective theories are an important tool for the explanation and prediction of human action and thinking, and a special methodology for their analysis has been developed. It is characteristic of this methodology that it is based on both hermeneutics and empiricism, which are integrated into a coherent framework. In the present article, it is argued that the concept of subjective theory and the corresponding methodology have a considerable potential for second language research. The methodology is discussed at some length, and its application to second language research is shown.

Ninety undergraduate students enrolled in Foreign language courses in French, Spanish and German were asked to respond to a questionnaire concerning their engagement in certain selected learning behaviors culled from recent literature on good language learners. The data reported by the students are described and analyzed according to level of language course, and language. They are also related to student's grades and instructors' evaluations of students' progress, effort and voluntary classroom participation. The main finding is that there is some evidence for a link between certain behaviors and student achievement. However, links between learning behavior and achievement seem dependent on course level and methodology, and suggest the possibility of a learning behavior/treatment interaction.

To investigate the role of context in reading development, a comparison of reading comprehension and processes was conducted between learners of Japanese as a second language in study abroad (SA; n = 15) and intensive domestic (in the United States) immersion (IM; n = 15) contexts. A significant difference was found between contexts in pretest to posttest gains on only one measure of reading comprehension, a self-assessment. Differences on the two other measures of comprehension—free-recall and vocabulary knowledge—were not significant. The self-assessment measure indicated that SA students felt more confident reading the second language than their IM counterparts. In terms of reading processes, think-aloud protocols showed significant differences in changes over time in the amount of monitoring understanding (less for IM than SA) and responding and reacting to text content affectively or emotionally (more for IM than SA). In the IM context, office-hour interaction with teachers influenced students to monitor comprehension less and more efficiently and to respond affectively to text more often. Variability in terms of gains on reading measures and contact with language and culture outside of class was greater for SA than for IM. The controlled IM setting and the open SA context contributed to differences in variability. The need for a variety of new measures designed to capture gains specific to any given context is discussed and specific suggestions for new measures are given.I wish to thank the following individuals for their help: Joe Collentine and Barbara F.

This study builds upon prior research dealing with the nature of discourse involving non-native speakers. In particular, we examine variables influencing native speaker foreigner talk and the form that speech modification takes. The data bases are (1) 80 taped telephone interviews between NNSs at two distinct proficiency levels, (interviewer) and NSs (interviewee), and (2) 20 NS-NS interviews. We consider five variables: 1) negotiation of meaning, 2) quantity of speech, 3) amount of repair (following a specific NNS request for repair), 4) elaborated responses, and 5) transparent responses. We find that the speech of NSs changes as a function of an NNS's ability to understand and be understood. We further suggest a general cognitive principle—transparency—underlying aspects of both foreigner talk and second language acquisition.

This experimental study investigates the differential effects of three conditions (nonnegotiated premodified input, negotiation without “pushed output” [Swain, 1985], and negotiation plus pushed output) on L2 learners' vocabulary comprehension and acquisition (receptive and productive). Analyses of variance performed on the data indicated that: (a) negotiated interaction had a positive effect on the comprehension of L2 words; (b) only negotiated interaction that incorporated pushed output appeared to have promoted both receptive and productive acquisition of words as well as an increase in productive word retention; and (c) negotiated interaction plus output did not promote receptive acquisition more than negotiation without output, but it was more effective in promoting productive acquisition. The findings of this study provide empirical evidence for the important role of negotiation in facilitating the comprehension and acquisition of L2 vocabulary, which suggests that output plays a key role within the negotiation process for productive lexical acquisition.

This article examines whether there is any difference between the effect of oral and written corrective feedback (CF) on learners’ accurate use of English articles. To this end, the current research presents the results of a quasi-experimental study with a pretest, immediate-posttest, delayed-posttest design, using 12 intact intermediate English-as-a-second-language classes with adult learners of various first language backgrounds. Five groups were formed: oral recasts (n = 26), oral metalinguistic (n = 26), written direct correction (n = 31), written direct metalinguistic (n = 32), and control (n = 28). All four experimental groups completed two 30-min communicative narrative tasks. For the oral CF groups, students were asked to retell a story during which CF was provided. For the written CF groups, students were first asked to rewrite a story and then given CF. The acquisition of English articles was measured by means of a speeded dictation test, a written narrative test, and an error correction test. One-way ANOVAs with post hoc comparisons indicated that all CF groups, except for oral recasts, significantly outperformed the control group in the immediate and delayed posttests. These findings show that, whereas implicit oral recasts that involve article errors were not facilitative to learning, the other CF types were effective in helping learners improve the grammatical accuracy of English articles irrespective of language analytic ability. Overall, these results suggest that the degree of explicitness of both oral and written CF—rather than the medium in which the CF is provided—is the key factor that influences CF effectiveness.

This study attempts to test aspects of the input hypothesis (Krashen, 1980, 1983, 1985) and Long's modification of it (Long, 1980, 1983a, 1985). Specifically, it experimentally tests the hypothesis that both input and interactional modifications facilitate second language acquisition, using Japanese as the target language. Three experimental groups were differentiated in terms of input and interaction conditions: (1) unmodified input with no interaction, (2) premodified input with no interaction, and (3) unmodified input with the chance for negotiated interaction. The groups were compared in terms of (a) their degree of comprehension of the input and (b) their subsequent retention of vocabulary items and acquisition of two Japanese locative structures. The results indicated that moment-to-moment comprehension was highest for the negotiated interaction group, whereas there was no significant difference between the two noninteraction groups. Furthermore, there was no correlation found between differences in moment-to-moment comprehension and gains in vocabulary recognition and acquisition of structures, though significant gains on both measures were found for all three groups. Discussion of these findings centers on the relationship between comprehension and acquisition.

This study addresses one of the functions of output proposed by Swain (1993, 1995, 1998). In particular, the activity of producing the target language may, under certain circumstances, prompt L2 learners to recognize some of their linguistic problems and bring to their attention something they need to discover about their L2. Two research questions were posed: (a) Does output promote noticing of linguistic form? and (b) Does output result in improved performance on the target form? In treatment phase 1, participants reconstructed a short passage after being exposed to it, followed by a second exposure to the same input material and a second reconstruction opportunity. In phase 2, participants wrote on given topics, followed by the presentation of a model written by a native speaker. Participants wrote a second time on the same topic. To test the noticing function of output, participants underlined parts of the sentences they thought were “particularly necessary” for subsequent (re)production. The control group was exposed to the same input materials but was not required to produce any output. Although phase 1 tasks resulted in noticing and immediate incorporation of the target form, the posttest performance failed to reveal their effects. In contrast, phase 2 tasks resulted in improvement on posttest 2. The results are discussed in terms of the efficacy of output in promoting noticing and learning and the conditions that may be required for output to be useful for SLA.

This study presents data collected from both natural settings and controlled experiments in order to describe native speaker responses to non-natives and to discuss what variables of a non-native's speech might elicit these responses. We present the results of three experiments. The first investigates native speaker reactions to requests for information by both native and non-native speakers in a natural setting. Experiment two is a controlled study focussing on two variables of non-native speech—pronunciation and grammar—and the response of native speakers to these variables. Experiment three examines the relationship between these variables and native speaker comprehension. Experiment four focuses on the effect of ordering on comprehensibility. We then discuss the role all of these factors play in the comprehensibility of non-native speech. We suggest that comprehensibility is achieved through a complex interaction of many factors and that it is comprehensibility which largely contributes to the use of foreigner talk by native speakers.

This response addresses the following points raised in the commentaries: (a) complementary learning mechanisms, the distinction between explicit and implicit memory, and the neuroscience of “noticing”; (b) what must and what need not be noticed for learning; (c) when frequency fails to drive learning, which addresses factors such as failing to notice cues, perseveration, transfer from L1, developmental readiness, thinking too hard, pedagogical input, and practicing; (d) attention and form-focused instruction; (e) conscious and unconscious knowledge of frequency; (f) sequences of acquisition—from formula, through low-scope pattern, to construction; (g) the Fundamental Difference hypothesis; (h) the blind faith of categorical grammar; (i) Labovian variationist perspectives; (j) parsimony and theory testing; (k) universals and predispositions; and (l) wanna-contractions. It concludes by emphasizing that language acquisition is a process of dynamic emergence and that learners' language is a product of their history of usage in communicative interaction.

In this study we compared two methods for correcting language transfer errors in the foreign language classroom. Thirty-two English-speaking college students enrolled in two sections of an introductory French course served as subjects. Eight commonly encountered English-to-French transfer errors were identified and randomly assigned to one of two teaching conditions for one class section; each error was assigned to the opposite condition for the other section. In both teaching conditions students began by translating English sentences into French. The sentences were such that an L1 (first language) transfer strategy produced correct translations (e.g., using savoir for some uses of “to know”). A sentence for which the transfer would not produce an adequate translation (e.g., a sentence requiring connaître) was then introduced in one of two ways. In one condition—what we have termed the Garden Path condition—students were given the new sentence and asked to translate as before. Their inevitable transfer error was then immediately corrected by the teacher. In the control condition students were simply given the correct French form and told that it differed from the English pattern (they were not given the opportunity to commit a transfer error). Student learning of the non-transferable form was assessed three times throughout the course of the semester, and at all time points performance was better in the Garden Path condition. We interpreted this finding as support for a cognitive comparison model of second language acquisition.
