Tasks have received increased attention in SLA research for the past decade, as has the role of focus on form. However, few empirical studies have investigated the relationship among tasks, focus-on-form techniques, and second language (L2) learning outcomes. To help address this gap, the present study examined how the task variable +/− contextual support combined with the focus-on-form technique known as recasting affects L2 morphosyntactic development. The participants were 90 adult learners of English as a foreign language, randomly assigned to one of five groups: four comparison groups and a control group. The comparison groups differed as to (a) whether they received recasts while describing photos and (b) whether they could see the photos while describing them. The control group only participated in the testing sessions. A pretest-posttest-delayed posttest design was employed to detect any improvement in participants’ ability to use the linguistic target, which was the past progressive form. Results from multifaceted Rasch measurement yielded two main findings. First, learners who received recasts but did not view photos outperformed learners who received recasts while viewing photos. Second, the group that viewed photos but did not receive recasts achieved greater L2 gains than the group who neither viewed photos nor received recasts.

Research suggests that students put more effort into language learning when they feel that it is a voluntary and self-relevant activity or they enjoy the process of mastering that language (i.e., they have a more self-determined orientation). This orientation is fostered when learners feel autonomous, competent, and related to others in their learning environment. We followed 162 university students of French across one semester to examine these causal claims longitudinally. Latent growth curve modeling showed that feelings of autonomy, competence, and relatedness and self-determined motivation increased across the semester while engagement declined. Parallel processes growth curve modeling showed that declines in engagement across the semester were attenuated to the extent that self-determined motivation increased. Auto-regressive cross-lagged analysis showed that, contrary to expectation, more engagement as the semester started predicted greater self-determination mid-semester (instead of vice versa), but these relations became reciprocal from mid-semester on. These findings are consistent with a dynamic model of motivation that emphasizes the reciprocal interplay between motivational constructs over the duration of a language course. The implications of these findings for motivation theory and instructional practices are discussed.

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.

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 investigated the acquisition of the comprehension of overt morphological case marking by adult native speakers of English who were learning Russian or German as a second language (L2). The Russian case-marking system is more complex than the German system, but it almost always provides the listener with case inflections that are reliable cues to sentence interpretation. Two approaches to learning of inflectional morphology were contrasted: the rule-based approach, which predicts that learning is determined by paradigm complexity; and the associative approach, which predicts that learning is determined by the cue validity of individual inflections. A computerized picture-choice task probed the comprehension of L2 learners by varying the cues of case marking, noun configuration, and noun animacy. The results demonstrated that learners of Russian use case marking much earlier than learners of German and that learners of German rely more on animacy to supplement the weaker case-marking cue. In order to further explore the underlying mechanisms of learning, a connectionist model was developed that correctly simulated the obtained results. Together, these findings support the view that adult L2 learning is associative and driven by the validity of cues in the input.

Reading affords opportunities for L2 vocabulary acquisition. Empirical research into the pace and trajectory of this acquisition has both theoretical and applied value. Charting the development of different aspects of word knowledge can verify and inform theoretical frameworks of word learning and reading comprehension. It can also inform practical decisions about using L2 readings in academic study. Monitoring readers’ eye movements provides real-time data on word learning, under the conditions that closely approximate adult L2 vocabulary acquisition from reading. In this study, Dutch-speaking university students read an English expository text, while their eye movements were recorded. Of interest were patterns of change in the eye movements on the target low-frequency words that occurred multiple times in the text, and whether differences in the processing of target and control (known) words decreased overtime. Target word reading outside of the familiar text was examined in a posttest using semantically neutral sentences. The findings show that orthographic processing develops relatively quickly and reliably. However, online retrieval of meaning remains insufficient for fluent word-to-text integration even after multiple contextual encounters.

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.

Interaction research about the role of language production in second language (L2) development has focused largely on modified output, specifically learners' responses to negative feedback (Iwashita, 2001; Loewen & Philp, in press; Mackey & Philp, 1998; McDonough, 2005; McDonough & Mackey, in press; Nobuyoshi & Ellis, 1993; Pica, 1988; Shehadeh, 2001). However, other processes involved in language production might help account for the beneficial relationship between interaction and L2 development. This paper reports the findings of two experiments that examined the occurrence of syntactic priming—a speaker's tendency to produce a previously spoken or heard structure—during interaction between L2 English speakers. Both studies used confederate scripting to elicit dative constructions from advanced English L2 speakers. In experiment 1, the participants (n = 50) were exposed to both prepositional and double-object dative primes. The linear mixed-model analysis indicated that syntactic priming occurred with prepositional datives only. In experiment 2, the English L2 participants (n = 54) received double-object dative primes only; results showed no evidence of syntactic priming. The implications are discussed in terms of the potential role of syntactic priming in driving L2 development in interactive contexts.This research was supported by grants (03135 and 04184) from the campus research board at the University of Illinois at Urbana-Champaign.

Reading in a second language (L2) can produce inefficient processing in otherwise proficient readers. This paper argues that mental translation during L2 reading may facilitate the generation and conservation of meaning by allowing the reader to represent portions of L2 text that exceed cognitive limits in a familiar, memory-efficient form. Fifty-one intermediate-level French students, in high, middle, and low reading ability groups, participated in think-aloud interviews while reading French texts. The relative frequency of translation use among these groups is compared at the beginning and end of a semester and is found to decrease with level of reading ability. The specific contexts in which students relied on translation are identified, and functional benefits and strategic uses of translation are discussed. Finally, hypotheses and questions are developed for future research.

This paper reports replications of studies of implicit artificial grammar (AG) learning and explicit series-solution learning with experienced second language learners in order to examine their population and content generalizability. As found by Reber, Walkenfeld, and Hernstadt (1991), there was significantly greater variance in explicit compared to implicit learning. In contrast to Reber et al.'s findings, intelligence quotient (IQ) was significantly negatively related to implicit learning. As found by Knowlton and Squire (1996), chunks that appeared with high frequency (high chunk-strength) in AG training influenced incorrect acceptance of ungrammatical transfer test items containing them but did not affect the judgments of grammatical items. In a third experiment, learners semantically processed sentences in Samoan, a novel language for this population. This experiment found little evidence for the content generalizability of these AG findings to the incidental learning of Samoan. Implicit AG and incidental Samoan learning had different patterns of correlation with cognitive abilities (IQ, working memory, and aptitude) and differed in sensitivity to chunk-strength. As found for AG learning, high chunk-strength negatively affected correct rejection of ungrammatical Samoan transfer test items. Additionally, high chunk-strength negatively affected correct acceptance of grammatical items. For these grammatical items, the number of chunks they contained—not their frequency during training—positively influenced grammaticality judgments.I gratefully acknowledge the helpful comments and advice on this paper given by the editors of this special issue, Jan Hulstijn and Rod Ellis, and also by Nick Ellis, Barbara Knowlton, and two anonymous SSLA reviewers.

German participles offer a distinction between regular forms that are suffixed with –t and do not exhibit any stem changes and irregular forms that all have the ending –n and sometimes undergo (largely unpredictable) stem changes. This article reports the results from a series of psycholinguistic experiments (acceptability judgments, lexical decision, and masked priming) that investigate regular and irregular participle forms in adult native speakers of German in comparison to advanced adult second language (L2) learners of German with Polish as their first language (L1). The most striking L1-L2 contrasts were found for regular participles. Although the L1 group’s performance was influenced by the combinatorial structure of regular participle forms, this was not the case for the L2 group. These findings suggest that adult L2 learners are less sensitive to morphological structure than native speakers and rely more on lexical storage than on morphological parsing during processing.

This paper explores the possibility that, contrary to the findings of past studies, the L1 and L2 mental lexicon may in fact be structurally similar, with depth of individual word knowledge determining a given word's degree of integration into the mental lexicon. The paper begins by reviewing the body of evidence relevant to the research question, and then presents the design and results of an investigation comparing nonnative and native speaker patterns of responses in light of depth of word knowledge scores. In discussing the results of the study, a tentative model for the process by which words are integrated into the mental lexicon is proposed, and the long-standing belief that a shift from predominantly syntagmatic to predominantly paradigmatic responses is indicative of lexical development is challenged.

Second-language (L2) sentence processing may differ from processing in a native language in a variety of ways, and it has been argued that one major difference is that L2 learners can only construct shallow representations that lack structural details (e.g., Clahsen & Felser, 2006). The present study challenges this hypothesis by comparing the extent to which advanced L1 Spanish-L2 English learners and English native speakers make use of the relative clause island constraint in constructing filler-gap dependencies. In offline acceptability judgment and online self-paced reading experiments that used stimuli adapted from Traxler and Pickering (1996), both the L2 group and the native-speaker control group demonstrated clear evidence for application of the relative clause island constraint. These findings suggest that advanced L2 learners not only build abstract structural representations but also rapidly constrain the active search for a gap location. These results cast doubt on the proposal that L2 learners are unable to build structural representations with grammatical precision.

This study examined the effects of acoustic variability on second language vocabulary learning. English native speakers learned new words in Spanish. Exposure frequency to the words was constant. Dependent measures were accuracy and latency of picture-to-Spanish and Spanish-to-English recall. Experiment 1 compared presentation formats of neutral (conversational) voice only, three voice types, and six voice types. No significant differences emerged. Experiment 2 compared presentation formats of one speaker, three speakers, and six speakers. Vocabulary learning was superior in the higher-variability conditions. Experiment 3 partially replicated Experiment 1 while rotating voice types across subjects in moderate and no-variability conditions. Vocabulary learning was superior in the higher variability conditions. These results are consistent with an exemplar-based theory of initial lexical learning and representation.Portions of these data were presented at the 143rd meeting of the Acoustical Society of America in Cancun, Mexico and at the Fourth International Conference on the Mental Lexicon in Windsor, Canada. The authors would like to thank Paola Rijos for help in data collection and scoring and the anonymous SSLA reviewers.

Schachter (1974) drew attention to the importance, in error analysis, of examining not only the L2 forms actually produced by the learners of a foreign language in their attempts to express themselves in L2, but also the L2 forms they seem consistently to avoid using. She also noted the close interrelation between such avoidance phenomena and the Contrastive Analysis approach to L2 teaching and learning: avoidance is the reverse side of negative transfer, since learners tend to avoid using in L2 those structures that have no parallel in their L1 and therefore provide them with no pattern for transfer. Of course, as Kleinmann (1977) has pointed out, “avoidance” implies that the structure in question is known to (i.e., can be passively recognized by) the learners, but not freely used by them; failure to use a structure or word that is unknown to the learners is an indication merely of ignorance, not of learning difficulty. Now a prime constructive purpose of error analysis is (or should be) to identify the sources of a learner's difficulties, as a necessary preliminary to helping him or her overcome them. Hence the importance of genuine avoidance phenomena that, when properly identified, can throw light on what would otherwise remain hidden recesses of uncertainty in the learner's mind. Levenston (1971) has convincingly argued, with numerous illustrations, that avoidance (“under-representation” in his terminology) of various English “clause (or group) structures” by Hebrew-speaking learners of English can be explained by the lack of Hebrew “translation-equivalents” for the English structures in question and the learners' consequent choice of less appropriate but more L1-equivalent structures. However, since Levenston was concerned not with avoidance phenomena as such, but rather with the evidence they provide of L1 interference with L2 learning and their stylistic effect on the learner's L2, he took the phenomena in question as established facts (on the basis, presumably, of his own teaching experience), without attempting to examine their frequency and extent.

The present study examines the relationship between syntactic development, or complexity, and overall accuracy evidenced in the written English of advanced adult foreign language learners. Similar acquisition profiles were found to exist for 30 learners across five language groups: Arabic, Chinese, Korean, Malay, and Spanish. Syntactic complexity, measured in number of clauses per T-unit, is found to be similar in all five groups. These advanced foreign language learners, who show similar patterns of error distribution, all show relative strength in syntax, what Newport, Gleitman, and Gleitman (1977) call a universal design feature of language, but relative weakness in morphology, which is always a language-specific system.

This paper investigates the various ways speakers manage problems and overcome difficulties in L2 communication. Following Dörnyei and Scott (1997), we distinguish four main sources of L2 communication problems: (a) resource deficits, (b) processing time pressure, (c) perceived deficiencies in one's own language output, and (d) perceived deficiencies in the interlocutor's performance. In order to provide a systematic description of the wide range of coping mechanisms associated with these problem areas (e.g., communication strategies, meaning negotiation mechanisms, hesitation devices, repair mechanisms), we adopt a psycholinguistic approach based on Levelt's (1989, 1993, 1995) model of speech production. Problem-solving devices, then, are analyzed and classified according to how they are related to the different pre- and post-articulatory phases of speech processing, and we illustrate the various mechanisms by examples and retrospective comments taken from L2 learners' data.

This study used the bibliometric method to examine the field of second language acquisition (SLA) between 1997 and 2018 to provide a systematic overview of the field and to discover major trends in SLA. Based on citation/cocitation information and keywords retrieved from Web of Science, this study performed three types of bibliometric analyses to identify the prominent scholarly documents, authors, research institutions, geographic regions, and research topics that have been highly influential in the field of SLA over the last two decades. The scientific network maps and the keyword analysis revealed a number of significant changes as well as new trends in the field.

Goo and Mackey (this issue) outline several apparent design flaws in studies that have compared the impact of different types of corrective feedback (CF). Furthermore, they argue that SLA researchers should stop comparing recasts to other types of CF because they are inherently different kinds of phenomena. Our response to their article addresses (a) the claim that the recast-learning relationship has been “settled,” (b) the misleading representation of our views on uptake, (c) the characterization of the CF comparison studies as being weak and invalid, and (d) Goo and Mackey’s recommendations concerning the most appropriate approach to investigating the effect of feedback on second language learning.
