In this paper we describe an experiment in explicit instruction that compares traditional form-focused instruction and what we call processing instruction. Traditional instruction involves explanation and output practice of a grammatical point. Processing instruction involves explanation and practice/experience processing input data, taking learner strategies in input processing as the starting point for determining what explicit instruction should look like. Pretest and posttest measures involving both a sentence-level interpretation (comprehension) task and a sentence-level production task were submitted to an analysis of variance. Results reveal significant gains in both comprehension and production for subjects who experienced processing instruction. For those experiencing traditional instruction, significant gains were made in production only.

This paper examines how the cognitive notion of attention has been employed in SLA and how it is understood in cognitive science. It summarizes recent research on attention from cognitive and neuroscience approaches. Some reformulations of problems raised in SLA research related to attention are proposed. Current research offers detailed ideas about attention and its component processes. These ideas, elaborated theoretically and empirically in cognitive neuroscience, may help untangle some important but difficult issues in SLA. Early, coarse-grained conceptions of attention, such as the limited-capacity metaphor or the automatic versus controlled processing dichotomy, are recast into an integrated human attention system with three separate yet interrelated networks: alertness, orientation, and detection. This finer grained analysis of attention is employed in a model of the role of attention in SLA.

Research on Second Language (L2) Acquisition, over the past ten years, has undergone substantial changes by shifting its focus of interest away from an analysis of linguistic structures alone, concentrating more on the learner himself or, rather, on the process of learning. It had become obvious that one of the major shortcomings in contrastive studies as well as in the usual kind of error analysis is that they lack thorough investigation of factors which determine the kind of approach a learner may take to acquire a second language. This again implies that it is more fruitful to study the process of learning itself instead of merely analysing its outputs. It is by now widely accepted that the learner takes an active part in the learning process and does not merely get trapped in structural gaps which linguists may find when comparing the source language (the learner's L1) and the target language (L2).

We used event-related brain potentials (ERPs) to investigate the contributions of explicit and implicit processes during second language (L2) sentence comprehension. We used a L2 grammaticality judgment task (GJT) to test 20 native English speakers enrolled in the first four semesters of Spanish while recording both accuracy and ERP data. Because end-of-sentence grammaticality judgments are open to conscious inspection, we reasoned that they can be influenced by strategic processes that reflect on formal rules and therefore reflect primarily offline explicit processing. On the other hand, because ERPs are a direct reflection of online processing, they reflect automatic, nonreflective, implicit responses to stimuli (Osterhout, Bersick, & McLaughlin, 1997; Rugg et al., 1998; Tachibana et al., 1999).

We used a version of the GJT adapted for the ERP environment. The experimental sentences varied the form of three different syntactic constructions: (a) tense-marking, which is formed similarly in the first language (L1) and the L2; (b) determiner number agreement, which is formed differently in the L1 and the L2; and (c) determiner gender agreement, which is unique to the L2. We examined ERP responses during a time period between 500 and 900 ms following the onset of the critical (violation or matched control) word in the sentence because extensive past research has shown that grammatical violations elicit a positive-going deflection in the ERP waveform during this period (e.g., the “P600”; Osterhout & Holcomb, 1992).

We found that learners were sensitive (i.e., showed different brain responses to grammatical and ungrammatical sentences) to violations in L2 for constructions that are formed similarly in the L1 and the L2, but were not sensitive to violations for constructions that differ in the L1 and the L2. Critically, a robust grammaticality effect was found in the ERP data for the construction that was unique to the L2, suggesting that the learners were implicitly sensitive to these violations. Judgment accuracy was near chance for all constructions. These findings suggest that learners are able to implicitly process some aspects of L2 syntax even in early stages of learning but that this knowledge depends on the similarity between the L1 and the L2. Furthermore, there is a divergence between explicit and implicit measures of L2 learning, which might be due to the behavioral task demands (e.g., McLaughlin, Osterhout, & Kim, 2004). We conclude that comparing ERP and behavioral data could provide a sensitive method for measuring implicit processing.This research was supported by a National Institutes of Health Individual National Research Service Award (NIH HD42948-01) awarded to Natasha Tokowicz and a National Institutes of Health Institutional National Research Service Award (T32 MH19102) awarded to Brian MacWhinney.

Second language (L2) anxiety has been the object of constant empirical and theoretical attention for several decades. As a matter of both theoretical and practical interest, much of the research in this domain has examined the relationship between anxiety and L2 achievement. The present study meta-analyzes this body of research. Following a comprehensive search, a sample of 97 reports were identified, contributing a total of 105 independent samples (N = 19,933) from 23 countries. In the aggregate, the 216 effect sizes (i.e., correlations) reported in the primary studies yielded a mean of r = −.36 for the relationship between L2 anxiety and language achievement. Moderator analyses revealed effects sizes to vary across different types of language achievement measures, educational levels, target languages, and anxiety types. Overall, this study provides firm evidence for both the negative role of L2 anxiety in L2 learning and the moderating effects of a number of (non)linguistic variables. We discuss the findings in the context of theoretical and practical concerns, and we provide direction for future research.

At least 40 studies have been conducted of the linguistic and conversational adjustments made by native speakers of a language using it for communication with non-native speakers. The modifications sometimes result in ungrammatical speech. Generally, however, they serve to provide input that is well-formed, a sort of linguistic and conversational cocoon for the neophyte second language acquirer. Most of the findings hold across age groups, social classes and settings, although some differences, both qualitative and quantitative, have been noted in these areas, too.

In making the adjustments described, native speakers appear to be reacting not to one, but to a combination of factors. These include the linguistic characteristics and comprehen-sibility of the non-native's interlanguage, but particularly his or her apparent comprehension of what the native speaker is saying. The adjustments appear to be necessary for second language acquisition, in that beginners seem unable to acquire from unmodified native speaker input. There is some doubt as to their sufficiency in this regard.

Working memory capacity refers to the ability to store and process information simultaneously in real time and has been shown to correlate highly with first language (L1) reading skill. This study examines the sensitivity of second language (L2) working memory capacity to differences in reading skill among advanced L2 learners. The index of working memory capacity used was the reading span test (Daneman & Carpenter, 1980). Subjects with larger working memory capacities scored higher on measures of reading skill, in contrast with the lack of strong correlations between measures of passive short-term storage (memory for strings of random words or digits) and the same reading measures. This result is consistent with an interpretation of the reading span test as an index of working memory capacity, in which capacity is defined functionally in terms of a trade-off between active processing and storage. Issues involved in investigating working memory capacity are discussed and the role of capacity limitations in models of L2 comprehension is considered.

We compared the acquisition of various dimensions of fluency by 28 students of French studying in three different learning contexts: formal language classrooms in an at home (AH) institution, an intensive summer immersion (IM) program, and a study abroad (SA) setting. For the purpose of oral data collection, students participated in oral interviews (similar to the Oral Proficiency Interview) at the beginning and the end of the semester and provided information regarding language use and interactions. Analyses included comparisons of gain scores as a function of the learning context and as a function of the time reported using French outside of class. The main findings that reached statistical significance include: (a) The IM group made significant gains in oral performance in terms of the total number of words spoken, in length of the longest turn, in rate of speech, and in speech fluidity based on a composite of fluidity measures. When compared to the AH group, the SA group made statistically significant gains only in terms of speech fluidity but fewer gains than the IM group. The AH group made no significant gains. (b) The IM students reported that they spoke and wrote French significantly more hours per week than the other two groups. The SA group reported using English more than French (although the difference was not statistically significant) and reported using significantly more English in out-of-class activities than the IM group. (c) Multiple regression analyses revealed that reported hours per week spent writing outside of class was significantly associated with oral fluidity gains.Appreciation is expressed to a number of organizations and individuals without whom this project would not have been brought to completion.

This study investigates the potentially facilitative effects of internal and external attention-drawing devices—output and visual input enhancement—on the acquisition of English relativization by adult English as a second language (ESL) learners. Specifically, the study addresses: (a) whether the act of producing output promotes noticing of formal elements in the target language (TL) input and affects subsequent learning of the form; and (b) whether such output- induced noticing and learning, if any, would be the same as that effected by visual input enhancement designed to draw learners' attention to problematic form features in the input. These questions were examined in a controlled experimental study in which the requirements of output and exposure to enhanced input were systematically varied. A computer-assisted reconstruction and reading task was used as the vehicle of presentation of the target input materials. The major findings are: (a) Those engaged in output-input activities outperformed those exposed to the same input for the sole purpose of comprehension in learning gains; (b) those who received visual input enhancement failed to show measurable gains in learning, despite the documented positive impact of enhancement on the noticing of the target form items in the input; and (c) in view of the above, no support was found for the hypothesis that the effect of input enhancement was comparable to that of output. The subsequent discussion centers on reexamining the construct of noticing and argues for the need to consider levels and types of processing in order to account for how sensory detection can lead to learning.

The relative effects of various types of negative feedback on the acquisition of the English dative alternation by 100 adult Spanish-speaking learners of English as a second language were investigated. Our objective was to determine empirically whether feedback can help learners learn the appropriate abstract constraints on an overgeneral rule. All subjects were trained on the alternation, which was presented in terms of a simple structural change. Subjects were divided into groups according to the type of feedback they received when they made an error. Specifically, upon making an error, Group A subjects were given explicit metalinguistic information about the generalization we hoped they would learn. Group B subjects were told that their response was wrong. Group C subjects were corrected when they erred, giving them a model of the response desired along with implicit negative evidence that their response was incorrect. Group D subjects, having made an error, were asked if they were sure about their response. The comparison group received no feedback.

This study examines effects of short, medium, and extended second language (L2) experience (3 months, 3 years, and 10 years of United States residence, respectively) on the production of five suprasegmentals (stress timing, peak alignment, speech rate, pause frequency, and pause duration) in six English declarative sentences by 30 adult Korean learners of English and 10 adult native English speakers. Acoustic analyses and listener judgments were used to determine how accurately the suprasegmentals were produced and to what extent they contributed to foreign accent. Results revealed that amount of experience influenced the production of one suprasegmental (stress timing), whereas adult learners' age at the time of first extensive exposure to the L2 (indexed as age of arrival in the United States) influenced the production of others (speech rate, pause frequency, pause duration). Moreover, it was found that suprasegmentals contributed to foreign accent at all levels of experience and that some suprasegmentals (pause duration, speech rate) were more likely to do so than others (stress timing, peak alignment). Overall, results revealed similarities between L2 segmental and suprasegmental learning.This research was partially supported by research grants from the University of Illinois and Brigham Young University.

Within both first and second language acquisition research, a critical or sensitive period for complete attainment has largely been substantiated in phonological studies, although it is questionable whether age should be examined in isolation from sociopsychological influences and the extent of exposure to the second language. This study sets out to challenge the Critical Period Hypothesis (CPH) by examining phonological performance among highly motivated subjects who use German daily as graduate student instructors and who have been immersed in the language through in-country residence, augmented by years of instruction in both language- and content-based courses. The methodology developed seeks to expand the realm of factors that are potentially conflated with age, such as instruction, motivation, suprasegmental training, and self-perception of productive accuracy, and other factors that have not been addressed in previous studies on ultimate attainment. Production tasks target sounds difficult for nonnative speakers (NNSs) according to contrastive analysis, and task types range in complexity from isolated words to sentences, paragraphs, and free speech. A mean rating was computed for each speaker, including native speaker controls, according to native speaker judgments. When averaged across all tasks, nonnative speaker performance did not overlap with native performance. However, several variables correlated significantly with outcome, including suprasegmental training, which indicated performance closer to native level.

For more than a decade now, a great deal of research has been done on the topic of written corrective feedback (CF) in SLA and second language (L2) writing. Nonetheless, what those research efforts really have shown as well as the possible implications for practice remain in dispute. Although L2 writing and SLA researchers often examine similar phenomena in similar ways, they do not necessarily ask the same questions. SLA-focused researchers investigate whether written CF facilitates the acquisition of particular linguistic features. In contrast, L2 writing researchers generally emphasize the question of whether written CF helps student writers improve the overall effectiveness of their texts. Understanding these differences in starting points is important because it provides a possible explanation for the conflicting methodologies and conclusions of various reviews on this topic (e.g., Ferris, 2003, 2004; Truscott, 1996, 2007). This article briefly traces the history of these two parallel lines of research on written CF and notes both contrasts and convergences. It then moves to a focused discussion of the possible implications and applications of this body of work for the L2 language and writing classroom and for future research efforts.

Results from a number of recent studies suggest that nativelike adult second language (L2) learners possess a high degree of language learning aptitude, the positive effects of which may have compensated for the negative effects of a critical period in these learners. According to the same studies, child learners seem to attain a nativelike command of the L2 regardless of high or low aptitude, which has led researchers to conclude that this factor plays no role in early acquisition. The present study investigates the L2 proficiency and language aptitude of 42 near-native L2 speakers of Swedish (i.e., individuals whom actual mother-tongue speakers of Swedish believe are native speakers). The results confirm previous research suggesting that a high degree of language aptitude is required if adult learners are to reach a L2 proficiency that is indistinguishable from that of native speakers. However, in contrast to previous studies, the present results also identify small yet significant aptitude effects in child SLA. Our findings lead us to the conclusions that the rare nativelike adult learners sometimes observed would all turn out to be exceptionally talented language learners with an unusual ability to compensate for maturational effects and, consequently, that their nativelikeness per se does not constitute a reason to reject the critical period hypothesis.

The developing oral English of approximately 100 second language learners (four intact classes) was examined in this study. The learners were native speakers of French (aged 10–12 years) who had received a 5-month intensive ESL course in either grade 5 or grade 6 in elementary schools in Quebec. A large corpus of classroom observation data was also analyzed.

Substantial between-class differences were found in the accuracy with which students used such English structures as progressive -ing and adjective–noun order in noun phrases. There was some evidence that these differences (which were not correlated with performance on listening comprehension tests) were due to differences in teachers' form-focused instruction. These findings are discussed in terms of current competing views of the role of form-focused instruction in second language learning.

The article reviews the methods of data collection employed in 39 studies of interlanguage pragmatics, defined narrowly as the investigation of nonnative speakers' comprehension and production of speech acts, and the acquisition of L2-related speech act knowledge. Data collection instruments are distinguished according to the degree to which they constrain informants' responses, and whether they tap speech act perception/comprehension or production. A main focus of discussion is the validity of different types of data, in particular, their adequacy to approximate authentic performance of linguistic action.

The purpose of the present study was to examine the relations between emotions, classroom environment, and willingness to communicate (WTC) using the advanced quantitative methodological procedure of doubly latent multilevel analysis. To this end, 1528 secondary school students from 65 different classrooms in Iran participated in the study. Results of the doubly latent multilevel analysis showed that a positive classroom environment is related to fostering WTC and enjoyment, while it reduces anxiety among students. Moreover, enjoyment was found as an important factor in increasing WTC at both student and classroom level, while anxiety reduced WTC only at the student level. Finally, the results of the study are discussed and pedagogical implications are provided for language teachers.

Progress toward establishing a model of lexical development to guide vocabulary acquisition research requires more precise specification of the various dimensions of lexical competence, the interrelationships among them, and how they interface with processes of word learning and use. Three dimensions of lexical competence are proposed: (a) partial to precise knowledge, (b) depth of knowledge, and (c) receptive to productive use ability. The relationship between the two knowledge dimensions and the acquisition of word meaning is considered, with emphasis on the complexity of the semantization1 process and on the need for redefining lexical development as both item-learning and system-changing. The adequacy of the three-dimensional description as a reflection of the process of vocabulary development is then discussed. Consideration of the nature of the developmental interrelationships among the dimensions raises two further questions: (a) Is depth of knowledge a prerequisite for developing precise comprehension? and (b) Are precise knowledge and depth of knowledge prerequisites for a word to become productive?

This study is a fine-grained analysis of extensive empirical data on the automatization of explicitly learned rules of morphosyntax in a second language. Sixty-one subjects were taught four morphosyntactic rules and 32 vocabulary items in an artificial language. After they had reached criterion on a set of metalinguistic tests of grammar and vocabulary, they engaged in systematic, computer-controlled comprehension and production practice for 8 weeks. Comprehension practice consisted of choosing between pictures displayed on the computer screen to match a sentence; production practice consisted of typing the correct sentence corresponding to a picture. All subjects were taught the same rules and then practiced them, and all subjects had the same amount of comprehension and production practice, but which rules were practiced in comprehension and which in production varied between groups. Results show that the learning of morphosyntactic rules is highly skill-specific and that these skills develop very gradually over time, following the same power function learning curve as the acquisition of other cognitive skills. These results are consistent with current skill acquisition theory.

The role of conversational interactions in the development of a second language has been central in the recent second language acquisition literature. While a great deal is now known about the way in which nonnative speakers interact with native speakers and other nonnative speakers, little is known about the lasting effects of these interactions on a nonnative's linguistic development. This paper specifically investigates the relationship among input, interaction, and second language production. Through data from native–nonnative speaker interactions in a direction-giving task, we show that both modified input and interaction affect task performance. However, only interaction has an effect on subsequent task performance.
