While the recent explosion of work on L2 discourse has provided researchers with a mass of data on the development of communicative abilities, we find that most of this work is predicated on a single (perhaps even curious) assumption: that all discourse, of which L2 discourse is taken as a subcategory, is intended by its speakers to be informative to some interlocutor (i.e., transmits a message via an acoustic or graphic conduit) and that the production of discourse entails the formulation of strategies on the part of speakers in order to maximize this transmission of data. That discourse is not communicative (i.e., sending and receiving information) by nature has, in fact, been long known, but overlooked, especially in L2 research. Malinowski pointed out as early as 1935 that:

Language is an activity the function of which is not an expression of thought or communication of ideas … the neglect of the obvious has often been fatal to the development of scientific thought. The false conception of language as a means of transferring ideas from the head of the speaker to that of the listener has, in my opinion, largely vitiated the philological approach to language (Malinowski, 1935, 9).

The article first calls attention to research on learner strategies and to the significant role that verbal report data have played in such research. While various research methods have been used to describe such strategies, verbal report measures are being used more and more as a means for describing cognitive processes in such areas as communicating, translating, test taking, and language learning. The article focuses just on the use of verbal report in describing learner strategies in language learning and language using. It is noted that information on learner strategies has evolved from partially intuited lists of strategies to empirically derived taxonomies that have as their ultimate purpose that of training learners to be more successful at language learning. Second, the controversy regarding the use of verbal report measures is discussed. Finally, the article describes a study that employed a variety of verbal report measures in an effort to understand better the strategies that teachers use in giving feedback on compositions and the strategies that learners use in handling this feedback in the English-foreign-languge and Portuguese-native-language classrooms, respectively.

This paper critically examines Tomlin and Villa's (1994) fine-grained analysis of attention and Leow's (1998) attempt to operationalize their model. Our position is that whereas Tomlin and Villa have moved the attention research forward by describing the nature of attentional processes and by pointing out that detection is a critical function of SLA, their claim that alertness and orientation are not necessary for detection to occur is currently unsupportable and does not reflect the complex nature of SLA. We argue that Leow's efforts to provide empirical support for this model fall short of that goal. Additionally, we cast doubt on Tomlin and Villa's position that awareness is not required for the detection of L2 data by arguing that the issue of awareness as well as the role of attentional functions must be viewed from a more interactive perspective in terms of the nature of the task, the nature of the linguistic item, and individual learner differences. We conclude by proposing research orientations that may help advance the discussion on this topic.

This paper argues that the study of second language acquisition theory and pedagogy can be enhanced through the use of time-series research designs. As quasi-experiments, time-series designs have features that improve internal validity. In addition, because these designs only require a small number of subjects, they are very practical, encouraging a greater number of empirical investigations of the many claims within the field and permitting the use of authentic measures that have high construct validity. The longitudinal nature of the designs also enhances construct validity, potentially yielding new insights into the effects of instruction on SLA. The designs utilized in two time-series studies (Kennedy, E., 1988, The Oral Interaction of Native Speakers and Non-Native Speakers in a Multicultural Preschool: A Comparison between Freeplay and Contrived NS/NSS Dyads, unpublished master's thesis, University of British Columbia, Vancouver; Mellow, J. D., 1996, April, A Longitudinal Study of the Effects of Instruction on the Development of Article Use by Adult Japanese ESL Learners, unpublished manuscript, University of British Columbia, Vancouver) are reviewed in order to illustrate the design features, the questions that may be investigated, and the issues that are raised in interpreting data.

This study examines the emergence of complex syntax in interlanguage (IL) development through a functionalist analysis of longitudinal, conversational IL data from two Vietnamese learners of English. The study focuses on discourse-pragmatic factors in the learners′ production and acquisition of complex syntax, specifically on their reliance on collaboration by interlocutors in the production of complex syntactic structures. Its findings offer a test of the utility of Givón's functionalist approach in SLA studies, and of claims by Hatch and others to the effect that “syntax develops out of conversation.” The interdependence of different linguistic levels in IL development is demonstrated, and the use of a variety of analytical units is shown to be critical in characterizing prepositional encoding in IL speech.

This study investigates the generalizability of claims by Logan (Klapp, Boches, Trabert, & Logan, 1991; Logan, 1985, 1988a, 1988b; Logan & Klapp, 1991) about the development of automaticity in the adult learning of alphabet arithmetic problems to the context of adult second language acquisition. Logan's proposal is that as individual solutions to problems accumulate in memory a transition in problem-solving procedures takes place. This transition involves the shift from an algorithm-based procedure for deducing correct solutions to direct retrieval of individual solutions or instances from memory. In the present study, second language learners of English were presented with a rule for understanding the morphological constraint on the dative alternation (Mazurkewich & White, 1984) and asked to judge the acceptability of 36 sentences presented in a training set. The sentences were controlled for frequency of presentation, one being presented eight times, one seven times, and so forth. When presented together with novel instances of the same type in a transfer set, reaction times to old instances were significantly faster. Reaction times to repetitions of the previously presented verbs in new frames and novel verbs in old frames were compared as a test of hypotheses about strategy switches in processing alternating and nonalternating verbs.

Recently there has been some debate about the appropriacy of different lexical units in pedagogy and research (e.g., Brown et al., 2020; Dang & Webb, 2016a; Kremmel, 2016; Laufer & Cobb, 2020; McLean, 2018; Nation, 2016; Nation & Webb, 2011; Vilkaitė-Lozdienė & Schmitt, 2020). The lexical unit (word types, lemmas, flemmas, word families) needs to be considered when developing wordlists, vocabulary tests, and vocabulary learning programs. It is also central to the lexical profiles of text and corpora, which indicate the vocabulary learning targets associated with understanding different types of discourse. Perhaps most importantly, the lexical unit of words found in vocabulary learning resources such as word lists and tests may affect their pedagogical value. The aim of this article is to highlight aspects of research and pedagogy that are affected by lexical units and describe issues that should be considered when operationalizing words in studies of vocabulary and learning resources.

Meta-analytic reviews collect available empirical studies on a specified domain and calculate the average effect of a factor. Educators as well as researchers exploring a new domain of inquiry may rely on the conclusions from meta-analytic reviews rather than reading multiple primary studies. This article calls for caution in this regard because the outcome of a meta-analysis is determined by how effect sizes are calculated, how factors are defined, and how studies are selected for inclusion. Three recently published meta-analyses are reexamined to illustrate these issues. The first illustrates the risk of conflating effect sizes from studies with different design features; the second illustrates problems with delineating the variable of interest, with implications for cause-effect relations; and the third illustrates the challenge of determining the eligibility of candidate studies. Replication attempts yield outcomes that differ from the three original meta-analyses, suggesting also that conclusions drawn from meta-analyses need to be interpreted cautiously.

In recent years, universities and secondary schools have increasingly used the ACTFL/ETS Oral Proficiency Interview (OPI) to measure the ability of learners to communicate in a foreign language. This article discusses the OPI in relation to current models of communicative skills and argues that the OPI fails to measure important aspects of communicative ability. Two Situation Tests, one written and one oral, are proposed as alternative measures of communicative ability and are described in detail. The two tests as well as the OPI were administered to American university students who had spent a year abroad studying French. This article reports on the changes in the communicative skills of the students during the year after their return to the United States. Statistical comparisons between the OPI and the Situation Tests are presented showing that the OPI is primarily a measure of grammatical competence. The article concludes with the claim that Situation Tests can provide a more complete assessment of communicative ability than the OPI.

In this focused methodological synthesis, the sample construction procedures of 110 second language (L2) instructed vocabulary interventions were assessed in relation to effect size–driven sample-size planning, randomization, and multisite usage. These three areas were investigated because inferential testing makes better generalizations when researchers consider them during the sample construction process. Only nine reports used effect sizes to plan or justify sample sizes in any fashion, with only one engaging in an a priori power procedure referencing vocabulary-centric effect sizes from previous research. Randomized assignment was observed in 56% of the reports while no report involved randomized sampling. Approximately 15% of the samples observed were constructed from multiple sites and none of these empirically investigated the effect of site clustering. Leveraging the synthesized findings, we conclude by offering suggestions for future L2 instructed vocabulary researchers to consider a priori effect size–driven sample planning processes, randomization, and multisite usage when constructing samples.

This article reports on the design and use of a profiler for lexical sophistication (i.e., use of advanced vocabulary), which was created to assess the lexical richness of intermediate and advanced Swedish second language (L2) learners’ French and Italian. It discusses how teachers’ judgments (TJs) of word difficulty can contribute to the methodology for lexical profiling and compares two methods, one purely frequency based and one modified on the basis of TJs of word difficulty. It has been suggested elsewhere that factors other than frequency play an important role in vocabulary acquisition. Here it is argued that cognates and thematic vocabulary related to teaching materials, although infrequent in target language (TL) corpora, should not necessarily be considered advanced and that analyses of learners’ lexical sophistication would benefit from integrating these aspects. In this study, the frequency-based method normally used in lexical profiling was modified by recategorizing some low-frequency words considered easy by many teachers. On the basis of the TJs, a basic vocabulary, which consisted mainly of high-frequency words but also of cognates and thematic words, was defined, which was based on the fact that teachers judged certain low-frequency cognates and thematic words as relatively easy. Using the modified method, learners’ lexical profiles were found to be more homogeneous within groups of learners at specific proficiency levels. The superiority of the new method over the purely frequency-based one was shown when comparing effect sizes. It is argued that this method gives a more correct picture of advanced L2 lexical profiles.

This article examines how changes in linguistic theory affect the debate between the fundamental difference hypothesis and the access-to-Universal Grammar (UG) approach to SLA. With a focus on subjacency (Chomsky, 1973), a principle of UG that places constraints on wh-movement and that has frequently been taken as a test case for verifying second language (L2) access to UG, we reanalyze earlier L2 findings in terms of a revised constraint, which effectively prohibits extraction out of subjects and adjuncts. We show that L2 learners indeed observe such a constraint on wh-movement, and, at the same time, we suggest that recent claims for a universal computational system (e.g., Chomsky, 1995; Uriagereka, 1999) make the respective roles of the first language and UG difficult to tease apart.

In the 12 years since Studies in Second Language Acquisition published its first thematic collection on L2 lexical issues, “The use and acquisition of the second language lexicon,” edited by S. Gass (1987), the centrality of lexical development in second language acquisition has received ever increasing recognition from researchers (see, for example, volumes by Arnaud & Béjoint, 1992; Coady & Huckin, 1997; Haastrup, 1991; Haastrup & Viberg, 1998; Harley, 1995, 1996; Hatch & Brown, 1995; Huckin, Haynes, & Coady, 1993; Meara, 1992; Nation, 1990; Schmitt & McCarthy, 1997; Schreuder & Weltens, 1993; Tréville, 1993; Tréville & Duquette, 1996). The 1987 collection was a leading foray into new territory, following a period of relative neglect of the lexicon in SLA. The issues taken up by its authors were quite diverse, ranging from the organization and components of the L2 lexicon, to aspects of acquisition such as cross-linguistic influence, restructuring, and rate, to L2 lexical-use issues such as retrieval and access. Since that time, a large body of L2 research and theory has developed around these and other topics, and it has become possible to deal comprehensively with single core issues in L2 lexical acquisition from multiple perspectives. The current collection is one such attempt, offering a set of related papers on the topic of incidental L2 vocabulary acquisition. Unlike the 1987 collection, which argued for recognition of the importance of the lexicon in a field dominantly concerned with the acquisition of syntax, the authors of the present collection assume the central importance of lexical acquisition.

There is presently a lively debate in second language (L2) acquisition research as to whether (adult) learners can acquire linguistic phenomena located at the interface between syntax and other modules, such as semantics, pragmatics, and lexical semantics, in contrast to phenomena that are purely syntactic in nature. For some researchers, the interface is precisely the place where fossilization occurs and the source of nonconvergence in L2 speakers. In this article we focus on the acquisition of the morphosyntax-semantics interface by examining the acquisition of mood in Spanish relative clauses by native speakers (NSs) of English. In particular, we focus on the contrast illustrated by Busco unas tijeras que corten “I am looking for scissors that cut-subj” versus Busco unas tijeras que cortan “I am looking for scissors that cut-ind.” When the indicative is used, there is a specific pair of scissors that the speaker is looking for. With the subjunctive, any pair of scissors will do, as long as it satisfies the condition expressed by the relative clause; the determiner phrase is nonspecific. In other words, we are dealing not with ungrammaticality, as both moods are possible in these contexts, but rather with differences in interpretation. General results showed that the learners could appropriately select the expected mood. We also saw that performance was not uniform across the various conditions tested. However, variability is not solely a product of L2 acquisition; we show it can be found in NSs as well.

This study focused on an instructional component often neglected when teaching the pronunciation of English as either a second, foreign, or international language—namely, the suprasegmental feature of lexical stress. Extending previous research on collaborative priming tasks and task repetition, the study investigated the impact of task and procedural repetition on eliciting target-stress patterns during collaborative priming tasks. It employed a pretest-posttest design with 57 Korean high school students who were randomly assigned to one of three groups: a control, priming with task repetition, and priming with procedural repetition. Learners participated in a pretest, two priming sessions, and two posttests over a 4-week period. Learners’ ability to produce target-stress patterns was measured through sentence read-aloud tasks. The task repetition group repeated the same primes and prompts twice, whereas the procedural repetition group performed priming tasks with different primes and prompts during two sessions. Results indicate that the amount of primed production was significantly more than unprimed production. Additionally, both experimental conditions promoted learners’ accurate production of target-stress patterns, though, in relation to long-term impacts, repeating the same task (i.e., same procedure and same content) twice was more effective than repeating the procedure for a second time with different content. The results are discussed in light of pronunciation teaching using auditory priming tasks.

This study is a conceptual replication of Rogers and Cheung’s (2018) investigation into distribution of practice effects on the learning of L2 vocabulary in child EFL classrooms in Hong Kong. Following a pretest, treatment, delayed posttest design, 66 primary school students (Cantonese L1) studied 20 vocabulary items over three training episodes under spaced-short (1-day interval) or spaced-long (8-day interval) learning conditions. The spacing of the vocabulary items was manipulated within-participants, and learning was assessed using crossword puzzles following a 4-week delay. While Rogers and Cheung (2018) resulted in minimal overall learning with a slight advantage for the spaced-short group, this study found large learning gains across the experimental conditions with no significant differences between the two learning schedules. Taken together, these results provide evidence that the results from previous research examining input spacing with adult populations in laboratory contexts might not generalize to authentic child learning contexts.

In this article, we challenge the notion that aptitude—operationalized as grammatical sensitivity as measured by the Words in Sentences section of the Modern Language Aptitude Test—is central to adult second language (L2) acquisition. We present the findings of a study on the acquisition of two properties of Japanese, head-final word order and case marking, by naïve learners of Japanese as a L2 who had no prior knowledge of this language or any other head-final, case-marking language. Participants underwent an input treatment in which they heard and saw basic subject-object-verb sentences in Japanese and were subsequently tested on these basic sentences and also on sentences to which they were not exposed during the treatment (i.e., polar questions and embedded clauses). Reading times on grammatical and ungrammatical sentences served as measures of underlying sensitivity to violations of grammatical word order for both the basic sentences and the novel sentences. Our results yielded three groups of learners: those who showed sensitivity to violations of basic word order, polar questions, and embedded clauses (parameter reset); those who showed sensitivity to violations of basic word order and polar questions only (partial parameter reset); and those who showed sensitivity to violations of basic word order only (no parameter reset). Because our measure of aptitude as grammatical sensitivity did not emerge as a factor distinguishing the three groups from one another, we argue that this component of aptitude is not a factor in whether learners are able to reset parameters. We also found that all participants, regardless of group, demonstrated sensitivity to case-marking violations, suggesting that aptitude as grammatical sensitivity plays no role in the acquisition of underlying features related to case or to the surface-level markings of case in Japanese.

The aim of this paper is to demonstrate the role played by linguistic universals in second language acquisition. Research reported here focuses on the acquisition of dative structures and dative questions in a passive context in English by French and Inuit (Eskimo) students. Data were also elicited from native English-speaking students to serve as the norm. The data are interpreted within the theory of markedness and core grammar, as well as Case theory. The results of the testing, showing that unmarked forms are acquired before marked ones, are consistent with the predictions made by the theory of markedness and the property of adjacency which is crucial for Case assignment.

This article examines the role played by functional approaches to linguistics in understanding second language acquisition (SLA). Central premises and tenets of functional approaches are described, and several key theoretical problems with functional efforts are detailed. The problem of referential management (the selection of nominal vs. pronominal NPs) in second language discourse production is examined. The general conclusions are drawn that (a) functional approaches to linguistics have a significant role to play in SLA studies, but (b) functional universals are insufficiently grounded theoretically and empirically at this point to contribute more than heuristic guidance to SLA theory.
