Foreign language learning contrasts with native language development in two key respects: It is unreliable and it is nonconvergent. At the same time, it is clear that foreign languages are languages. The fundamental difference hypothesis (FDH) was introduced as a way to account for the general characteristics of foreign language learning. The FDH was originally formulated in the context of the theory of rich Universal Grammar, and this theory has guided much foreign language acquisition research over the past two decades. However, advances in the understanding of language have undermined much of the supporting framework.

The FDH—indeed all of SLA research—must be rethought in light of these advances. It is proposed here that (a) foreign language grammars make central use of patches, which are also seen as peripheral phenomena in native languages; (b) non-domain-specific processes are used in foreign language acquisition, but that these are also employed—although more effectively because they are integrated into the language system—by native language development; and (c) foreign language online processing relies heavily on the use of shallow parses, but these are also available in native language processing, although less crucially.

This paper is a longitudinal study of the acquisition of pragmatic competence. Advanced adult nonnative speakers of English were taped in advising sessions over the course of a semester. Two speech acts, suggestions and rejections, were analyzed according to their frequency, form, and successfulness and compared with similar data gathered for native speakers. The nonnative speakers showed change toward the native speaker norms in their ability to employ appropriate speech acts, moving toward using more suggestions and fewer rejections, and became more successful negotiators. However, they changed less in their ability to employ appropriate forms of the speech acts, continuing to use fewer mitigators than the native speakers. Furthermore, unlike native speakers, they also used aggravators. We claim that these results may be explained by the availability of input: Learners receive positive and negative feedback from the advisor regarding the desirability and outcome of particular speech acts, but they do not receive such feedback regarding the appropriateness of the forms of such speech acts.

Current research into second-language learning has tended to ignore (or at best to treat incidentally) a linguistic phenomenon that once used to be a particular preoccupation of applied linguists, the interference error. Instead, the limelight is now firmly focussed on developmental phenomena, with many studies using an approach to data gathering and analytical methodology strongly reminiscent of research into child language acquisition and language contact. There have been specific attempts to establish developmental sequences in the TL, in morpheme acquisition, for instance, so as to compare first and second language learning, and not a little attention is now being paid to such sociolinguistic notions as variability, continua and simplification. In other words, the main emphasis in interlanguage research has shifted from a rather static error-oriented view of language learning to a dynamic view of learners' language as a constantly evolving system. The calls for longitudinal studies of interlanguage of the late sixties and early seventies have not gone unheeded, eve if the word ‘longitudinal’ is sometimes rather liberally interpreted, as in those cases where a tacit (and probably justifiable) assumption is made that studying groups of learners of varying proficiency in respect of given TL features at one and the same time is really the same as following the progress of one group over a long period.

This paper reexamines claims that second language learners are more accurate at judging long-distance object extraction than subject extraction and that the difference in accuracy is due to processing factors rather than differences in underlying competence. Although previous studies have reported robust effects for the subject/object asymmetry, the global nature of the response measures leaves open the question of whether the subject gap is in fact the locus of difficulty for second language learners. Using many of the same stimuli sentences from original research in combination with a theory of principle-based parsing, this study employs the moving window display technique to collect on-line measures of processing long-distance wh-extraction. Twenty-five advanced Chinese-speaking ESL learners provided grammaticality judgments in two presentation conditions: full-sentence, where judgment reaction times are measured from sentence onset to the learner's judgment; and word-by-word reading, where word-by-word latencies are collected in addition to judgments. The accuracy and reaction time results from the full-sentence condition replicated previous findings. The word-by-word results confirm that it is the subject gap that is the source of difficulty for the learners. Claims in the literature that principles of Universal Grammar are not available to adult learners are not supported by these results, which show that parsing, and not grammatical competence, is the source of difficulty on performance with subject extraction sentences.

This paper is a report on a quasi-experimental study designed to investigate contributions of form-focused instruction and corrective feedback to the development of interrogative constructions in the oral performance of English-as-a-second-language (ESL) learners. The subjects were young francophone learners of English (age 10–12) receiving intensive ESL instruction. Their accuracy and developmental progress in the use of interrogative structures was measured prior to a 2-week period of instructional treatment. Immediate and delayed posttests were administered after the instruction. The language produced by the instructors while teaching interrogative structures was examined in relation to the learners' oral performance. Similar analyses were carried out with a comparison group. The results support the hypothesis that form-focused instruction and corrective feedback provided within the context of communicative interaction can contribute positively to second language development in both the short and long term.

This paper reports the results of an exploratory cross-sectional study of pragmatic development among three groups of primary school students in Hong Kong who completed a cartoon oral production task (COPT) designed to elicit requests, apologies, and compliment responses. The first two of these speech acts are among the most well represented in the pragmatics literature and are also included in the Hong Kong English language syllabus for primary schools. The latter has also been studied extensively but is not part of the syllabus. Data was collected in Cantonese using the same instrument. Although a number of developmental patterns are revealed—particularly in choice of request strategy, frequency of supportive moves, and use of adjuncts with apologies and compliment responses—there is little evidence of sensitivity to situational variation or pragmatic transfer from Cantonese. This study adds to the small, but growing, body of research on pragmatic development in a second language.

It is now generally accepted that second language (L2) acquisition can take place as a result of learning how to communicate in the L2. It is less clear, however, whether the kind of communication that occurs in a classroom is sufficient to ensure development of full target language competence. This article examines the extent to which the opportunities for communication in an English as a Second Language (ESL) classroom result in the acquisition of one particular illocutionary act—requests. A total of 410 requests produced by two child learners over 15–21 months were examined. The results suggest that although considerable development took place over this period, both learners failed to develop either the full range of request types or a broad linguistic repertoire for performing those types that they did acquire. The learners also failed to develop the sociolinguistic competence needed to vary their choice of request to take account of different addressees. One explanation for these results is that although the classroom context fostered interpersonal and expressive needs in the two learners, it did not provide the conditions for real sociolinguistic needs.

Context of learning, such as whether a learner studies a second language (L2) in a formal classroom—“at home” or abroad—may be a key factor in developing grammatical and lexical abilities. Yet, little empirical data is available comparing the effects of study abroad (SA) and formal instruction “at home” (AH) experiences on such development (Freed, 1995). The scant research that exists presents conflicting results (DeKeyser, 1986, 1991; Isabelli, 2002; Lennon, 1990; Regan, 1995; Ryan & Lafford, 1992; Schell, 2001). This paper provides a multivariate analysis (see Biber, 1988) of the effects of learning context on grammatical and lexical abilities in oral conversational discourse. The data compare the abilities of two groups before and after studying Spanish as an L2 for approximately one semester (N = 46): (a) a SA group in Alicante, Spain, and (b) a formal-classroom AH group at an American university. The corpus comprises oral segments produced by the learners in an Oral Proficiency Interview before and after the experimental period. In a corpus-based analysis, each segment was transcribed and tagged for various lexical and grammatical features. In two discriminant analyses, I identified various grammatical and lexical features that differentiated the two groups in terms of program gains. The results indicated that the AH context facilitated more development on discrete grammatical and lexical features. However, quantitative discourse analyses of the corpus revealed that the SA group achieved better narrative abilities and could produce language that was more semantically dense. The data are explained in consideration of the SA group's improved fluency and sociolinguistic pressures that distinguished its learning conditions.I would like to express my gratitude to the Council on International Educational Exchange, Barbara F.

The extent to which form-focused instruction contributes to the acquisition of second language implicit knowledge is controversial. Whereas Krashen (1993) has argued that the effects of FFI on acquisition are peripheral, N. Ellis (this issue) sees FFI as facilitative and even necessary for developing implicit L2 knowledge. This article examines the role of FFI in developing implicit knowledge by reviewing 11 studies that have examined the effect of FFI on learners' free production. The review suggests that FFI can contribute to the acquisition of implicit knowledge and points to two variables that appear to influence its success—the choice of the target structure and the extent of the instruction. FFI involving extensive instruction directed at “simple” structures was more likely to succeed. However, limited instruction directed at complex structures also proved effective, provided that the target structures are readily available in noninstructional input.

This study examines the role of task-based conversation in second language (L2) grammatical development, focusing on the short-term effects of both negative feedback and positive evidence on the acquisition of two Japanese structures. The data are drawn from 55 L2 learners of Japanese at a beginning level of proficiency in an Australian tertiary institution. Five different types of interactional moves made by native speaker interlocutors during task-based interaction were identified, by way of which learners received implicit negative feedback and positive evidence about the two target structures. The relative frequency of each interactional move type was calculated, and associated changes in the learners' performance on immediate and delayed posttests were examined. It was found that, although native speaker interactional moves containing positive evidence about the two target structures were 10 times more frequent during task-based language learning than those containing implicit negative feedback, only learners who had an above-average score on the pretest benefited from the positive evidence provided. Implicit negative feedback, on the other hand, had beneficial effects on short-term development of the grammatical targets regardless of the learner's current mastery of the target structures. Moreover, recasts were found to have a larger impact than other conversational moves on short-term L2 grammatical development.

This study analyzed phonological short-term memory (PSTM) and working memory (WM) and their relationship with vocabulary and grammar learning in an artificial foreign language. Nonword repetition, nonword recognition, and listening span were used as memory measures. Participants learned the singular forms of vocabulary for an artificial foreign language before being exposed to plural forms in sentence contexts. Participants were tested on their ability to induce the grammatical forms and to generalize the forms to novel utterances. Individual differences in final abilities in vocabulary and grammar correlated between 0.44 and 0.76, depending on the measure. Despite these strong associations, the results demonstrated significant independent effects of PSTM and WM on L2 vocabulary learning and on L2 grammar learning, some of which were mediated by vocabulary and some of which were direct effects.

This study investigated the relationship between receptive and productive vocabulary size. The experimental design expanded upon earlier methodologies by using equivalent receptive and productive test formats with different receptive and productive target words to provide more accurate results. Translation tests were scored at two levels of sensitivity to measure receptive and productive knowledge of meaning and form. The results showed that total receptive vocabulary size was larger than productive vocabulary. When responses were scored for fuller knowledge, receptive vocabulary size was also found to be greater than productive vocabulary size in each of three word frequency bands, with the difference between receptive and productive knowledge increasing as the frequency of the words decreased. However, when responses were scored for partial knowledge, there was little difference among vocabulary sizes at each frequency band. The findings also indicated that receptive vocabulary size might give some indication of productive vocabulary size. Learners who have a larger receptive vocabulary are likely to know more of those words productively than learners who have a smaller receptive vocabulary.

This paper reports on a study that examines the pattern of interaction in child native speaker (NS)–nonnative speaker (NNS) conversation to determine if the NSs provide negative feedback to their NNS conversational partners. It appears that just as children are able to modify their input for their less linguistically proficient conversational partners in first language acquisition (Snow, 1977), so too are children able to modify their interactions for NNS peers in the second language acquisition process and, in doing so, provide negative feedback. Two forms of NS modification were identified in this study as providing reactive and implicit negative feedback to the NNS. These were (a) negotiation strategies, including repetition, clarification requests, and comprehension checks, and (b) recasts. The results indicated that NSs respond differentially to the grammaticality and ambiguity of their NNS peers' conversational contributions. Furthermore, NS responses (negotiate, recast, or ignore) appeared to be triggered by the type and complexity of NNS errors, although it was more likely overall that negative feedback would be used rather than the error ignored. Additionally, evidence suggested that negative feedback was incorporated by the NNSs into their interlanguage systems. This indicates that not only does negative evidence exist for child second language learners in these types of conversations, but that it is also usable and used by them in the language acquisition process.

A fundamental question in the study of second language (L2) fluency is the extent to which temporal characteristics of speakers’ first language (L1) productions predict the same characteristics in the L2. A close relationship between a speaker’s L1 and L2 temporal characteristics would suggest that fluency is governed by an underlying trait. This longitudinal investigation compared L1 and L2 English fluency at three times over 2 years in Russian- and Ukrainian- (which we will refer to here as Slavic) and Mandarin-speaking adult immigrants to Canada. Fluency ratings of narratives by trained judges indicated a relationship between the L1 and the L2 in the initial stages of L2 exposure, although this relationship was found to be stronger in the Slavic than in the Mandarin learners. Pauses per second, speech rate, and pruned syllables per second were all related to the listeners’ judgments in both languages, although vowel durations were not. Between-group differences may reflect differential exposure to spoken English and a closer relationship between Slavic languages and English than between Mandarin and English. Suggestions for pedagogical interventions and further research are also proposed.

This article reports on a strategy training study that investigated the lexical processing strategies (LPSs; ignore, consult, infer) used by L2 learners when they encounter unfamiliar vocabulary while reading and the impact of these strategies on vocabulary learning. A time-series with repeated-measures design was used. Introspective data were gathered from eight participants (Francophone university students, intermediate ESL proficiency) on eight texts over 5 months to elicit LPS use on self-identified unfamiliar words. Then, 1 week after each reading, participants completed a cued recall task to measure their learning of these words. An analysis of overall LPS use (changes in patterns and effectiveness of strategy use with LPS-focused instruction) and word retention rates demonstrates the potential for vocabulary learning through reading and indicates that some LPSs lead to higher retention rates than others. This research increases our understanding of the role of LPS use in vocabulary learning and suggests some reevaluation of current pedagogic practice.

In this paper we show that supplying positive evidence in the second language (L2) classroom does not necessarily trigger the appropriate L2 value of a parameter of Universal Grammar. The parameter we investigate is the verb movement parameter of Pollock (1989), which accounts for the fact that English and French adverbs differ as to where they occur in relation to the verb: In French the verb raises past the adverb, allowing the order SVAO but not SAV, whereas in English the verb does not raise, allowing SAV but not SVAO. Fifty-four francophone children (aged 11) in intensive English-as-a-second-language programs in Quebec, Canada, were exposed to a 2-week input flood of specially prepared materials containing English adverbs used naturalistically. No form-focused instruction or negative evidence on adverb placement was provided. Subjects were pretested immediately prior to the input flood, posttested immediately afterward, and again 3 weeks later, on four different tasks. On all tasks there is a change between pretest and posttest behavior, namely, a dramatic increase in use of the English SAV order but little or no decline in incorrect usage of SVAO. Results are also compared to groups reported in White (1991a, 1991b); the subjects in the present study differ from both groups in the previous studies. The results of the present study suggest that positive evidence does not serve to preempt the first language parameter setting in this case; acquiring the correct English SAV order did not lead to loss of incorrect SVAO. Implications of this result for theories of preemption and parameter setting in L2 acquisition are discussed.

Thirty years ago, Dell Hymes (1972) observed that knowing what goes on outside the school setting is necessary to understanding what goes on inside. He noted further that “the key to understanding language in context is to start not with language but with context … [and then to] systematically relate the two” (pp. xix–lvii). Recently, the importance of learning context has stirred debate within SLA circles, and two coexisting lines of research have contributed to the overall picture that researchers and pedagogues have on SLA. On the one hand, scholars such as Long (1997) contended that it is important to provide an understanding of the acquisition process in psycholinguistic terms relatively independent of external factors (e.g., sociolinguistic variables or the particular methodology employed in a classroom). Researchers such as Firth and Wagner (1997) contended that the best predictive models of SLA consider the interaction of social activity and psycholinguistic elements.

Learning a second/foreign language (L2) is a long process and L2 learners certainly will encounter setbacks and discouragements during this process. However, their reactions to these failures might be different based on their perceptions of L2 learning ability and their subsequent effort put into L2 learning. Based on this, the present study aimed at exploring two underresearched constructs within the field of applied linguistics, namely grit (continuous effort and interest for long-term goals) and language mindset (individuals’ perceptions of their language learning ability). We had five main aims: to examine (a) the factor structure of grit, (b) the factor structure of language mindset, (c) whether there are gender differences in grit or language mindset, (d) the relationships between language mindset and grittiness, and (e) the roles of grit and language mindset as predictors of L2 achievement. To address these aims, a total number of 1,178 university students who were taking general English courses took part in our study and completed the questionnaires. Results of confirmatory factor analysis indicated that the two-factor structure for both grit and language mindset fit the data better than the single-factor structure. We also tested several structural equation models and found that a growth language mindset weakly, but positively, predicted one component of grit (perseverance of effort, or POE), but not the other (consistency of interest, or COI). A fixed language mindset did not predict POE, but did negatively predict COI. Finally, only growth language mindset was a weak, positive predictor of L2 achievement. At the end, theoretical and pedagogical implications regarding the role of grit and language mindset in L2 learning are presented.

This study examined the componential structure of second-language (L2) speaking proficiency. Participants—181 L2 and 54 native speakers of Dutch—performed eight speaking tasks and six tasks tapping nine linguistic skills. Performance in the speaking tasks was rated on functional adequacy by a panel of judges and formed the dependent variable in subsequent analyses (structural equation modeling). The following independent variables were assessed separately: linguistic knowledge in two tests (vocabulary and grammar); linguistic processing skills (four reaction time measures obtained in three tasks: picture naming, delayed picture naming, and sentence building); and pronunciation skills (speech sounds, word stress, and intonation). All linguistic skills, with the exception of two articulation measures in the delayed picture naming task, were significantly and substantially related to functional adequacy of speaking, explaining 76% of the variance. This provides substantial evidence for a componential view of L2 speaking proficiency that consists of language-knowledge and language-processing components. The componential structure of speaking proficiency was almost identical for the 40% of participants at the lower and the 40% of participants at the higher end of the functional adequacy distribution (n = 73 each), which does not support Higgs and Clifford’s (1982) relative contribution model, predicting that, although L2 learners become more proficient over time, the relative weight of component skills may change.

This study is a quantitative and qualitative investigation of the effects of awareness, or the lack thereof, on 32 adult second or foreign language (L2) learners' subsequent intake and written production of targeted Spanish morphological forms. Think-aloud protocol data, gathered while learners completed a problem-solving task (a crossword puzzle) and postexposure assessment tasks (a multiple-choice recognition task and a written production task), were used to measure awareness or the lack thereof, and morphological learning was assessed by learners' performances on the two postexposure tasks. From a theoretical perspective, no dissociation between awareness and further processing of targeted forms was found in this study, the results of which are compatible with the claim that awareness plays a crucial role in subsequent processing of L2 data (e.g., Robinson, 1995; Schmidt, 1990, 1993, 1994, 1995). From a methodological perspective, the data collection procedure clearly underscores the need for studies that investigate the roles of attention and awareness in second language acquisition (SLA) to gather as much data as possible from different sources that reveal participants' internal processes. By attempting to ascertain what learners really attend to or are aware of, or both, while exposed to or interacting with L2 data, such information can also address the methodological issue of how representative learners' performances in experimental groups really are in studies conducted under an attentional framework in SLA.
