This article examines the relationships between second language acquisition (SLA), instructed second language acquisition (ISLA), and language teaching by examining them from the lens of the research on the acquisition and teaching of second language (L2) tense-aspect in the last 20 years (2000–2021). Review 1 examines 56 instructional effect studies on the acquisition of L2 tense-aspect, and Review 2 examines 38 pedagogical proposals for the teaching of L2 tense-aspect. The reviews investigate to what extent instructional effect studies and pedagogical proposals with tense-aspect as the target of investigation and instruction (a) provide a linguistic description of the instructional target, (b) engage with previous research, (c) implement results from previous research to design assessment or instruction, and (d) include elaborate descriptions of teaching interventions and teaching materials. The results show that there are clear attempts to establish connections between research and practice. However, neither instructional effect studies nor pedagogical proposals always engage with the SLA literature on the acquisition of tense-aspect; nor do they engage fully with language teaching.

Twenty years ago, a state-of-the-art review in SSLA marked the coming of age of the study of temporality in second language acquisition. This was followed by three monographs on tense and aspect the next year. This article presents a state-of-the-scholarship review of the last 20 years of research addressing the aspect hypothesis (AH) (Andersen, 1991, 2002; Andersen & Shirai, 1994, 1996), the most tested hypothesis in L2 temporality research. The first section of the article gives an overview of the AH and examines its central tenets, and then explores the results of empirical studies that test the hypothesis. The second section considers studies that have investigated four crucial variables in the acquisition of temporality and the testing of the AH. The third section discusses theoretically motivated areas of future research within the framework of the hypothesis.

This article reviews the recent research on formulaic language in pragmatics from three perspectives: foundational issues, recurrent research questions, and the populations studied. Examination of foundational issues, including definitions and operationalization of the concept of formula in pragmatics, shows the way in which pragmatics understands formulaic language and what it contributes to the study of formulaic language, namely, a strong sense of social contract. Recurrent themes in contemporary investigations include how formulas are used in general and in specific contexts, determining how extensive the use of formulas is, attitudes toward formulas, acquisition of formulas in second language (L2) pragmatics, and formulas in pragmatics pedagogy. The third section reviews pragmatic research according to language community, defined for the purposes of this review as first language (L1; native-speaker communities), L2, cross-cultural comparisons, indigenized varieties, and lingua franca communities. The investigation of formula use by different communities addresses questions of the particular and the universal in formula use and the importance of community and community membership.

This article provides a comprehensive synthesis of research on language attrition to date, with a view to establishing a theoretically sound basis for future research in the domain of second language (L2) attrition. We identify the variables that must be tracked in populations who experience language loss, and we develop a general model for the assessment of the processes involved. This critical review suggests that future research in this domain should establish baselines for attainment against which to measure attrition, and that learners must be compared to themselves in longitudinal designs that involve periodic assessment of both linguistic and extralinguistic factors. In the proposed model, populations are defined as sets of variables, which are subject to change following shifts in discrete time periods in the general process of acquisition and attrition. A working model is elaborated for the assessment of L2 attrition and retention, which, we hope, might encourage additional work in this area.

The task of all language learners is to match form and meaning. This study investigates the associations of form and meaning in the developing tense and aspect systems of adult learners of English as a second language. A cross-sectional study of 135 learners at six levels of proficiency was conducted using a cloze passage and compositions on the same topic. The interlanguage tense and aspect systems can be characterized as showing high formal accuracy, but relatively lower appropriate use across all levels. During the period when appropriate use lags behind formal accuracy, learners seem to associate form and meaning through alternative interim hypotheses related to lexical aspect and discourse function.

The use of formulaic expressions by second language learners has received little attention from second language acquisition research investigating interlanguage temporal systems. Instead, this field of inquiry has emphasized the productive use of verbal morphology by employing type-token analyses. This paper considers the proposed developmental sequence of formula > low-scope pattern > construction in the emergence of future expression in a longitudinal study of 16 adult learners of English as a second language. The findings suggest that the use of formulaic expressions may be subject to individual variation and that learners may use formulaic expressions to different degrees when developing form-meaning associations even in the same grammatical subsystem, such as the tense-aspect system. The findings also suggest, however, that the practice of favoring type over token analysis as a matter of course may eliminate valuable information about the emergence and development of temporal expression.

This article surveys the development of second language acquisition research in the area of tense and aspect. Research in the area has grown from the incidental investigation of tense-aspect morphology as part of the morpheme-order studies to investigations of the construction of interlanguage temporal semantics. Going beyond verbal morphology, many studies investigate a full range of temporal expression, including the use of pragmatic and lexical means. Much recent research also draws on theories of inherent, or lexical, aspect. An emphasis on the relation of form and meaning characterizes both the form-oriented approach and the semantic-oriented approach, the competing research paradigms that currently guide our work. The increase in scholarly activity in this domain of second language acquisition, as reflected not only in the number of studies undertaken but in the number of target languages investigated, bodes well for the understanding of temporality in second language.

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

Imagine a three-year longitudinal study of the acquisition of multiple target languages by learners of different language backgrounds. It may sound like an idealized example from a research-methods lecture, but it is the actual design of the European Science Foundation inquiry into adult second language acquisition and the latest report released by Benjamins, a substantial revision of Volume 5 of the final report on temporality (Bhardwaj, Dietrich, & Noyau, 1988). This volume reports on the acquisition of temporality in five target languages (English, German, Dutch, French, and Swedish) by 21 learners of six source languages (Punjabi, Italian, Turkish, Arabic, Spanish, and Finnish) with learners from two source languages for each target language. The volume has eight chapters written by the main authors and cooperating contributors: “Introduction” (Dietrich & Perdue), “Frame of Analysis” (Klein), five chapters on the acquisition of temporality by target language—English (Klein), German (Dietrich), Dutch (Klein, Coenen, van Helvert, & Hendricks), French (Noyau, Houdaïfa, Vasseur, & Véronique), and Swedish (Noyau, Dorriots, Sjöström, & Voionmaa)—and “Conclusions” (Klein, Dietrich, & Noyau).

This paper investigates the nature of input available to learners in the institutional setting of the academic advising session. The advisory session, an unequal status encounter that by nature is a private speech event and cannot be observed by other learners, provides a starting point for the investigation of real and perceived availability of input. Evidence for the realization of speech acts as well as appropriate content and form, positive evidence from peers and status unequals, the effect of stereotypes, and limitations of a learner's pragmatic and grammatical competence are factors that may influence the course of development of interlanguage pragmatics in the institutional setting.

This thematic issue on the construction of discourse by nonnative speakers brings together papers from a variety of perspectives. The papers illustrate how our understanding of various aspects of learner language are enriched by viewing them when situated in text. Of the variety of analyses used in this issue, the most well-known to SLA researchers investigates the organization of the text itself and the learners' ability to structure such a text. Other investigations in this issue include the study of grammatical features of interlanguage that contribute to the structure of the text and, conversely, the study of textual features that determine the use of grammatical features: neither of which may be accessible through the analysis of sentence-level production. In addition to grammatical features, the study of lexical development can be enhanced through the study of text. Whereas lexical inventories alone do not reveal the true nature of the learners' lexicon, a study of text reveals not only which lexical items are selected by learners but also how they are employed in discourse. These studies of text extend to other areas of linguistic competence as well. In the study of pragmatic competence, viewing speech acts as they are situated in speech events (e.g., the speech act of recommendation in the speech event of a letter of recommendation) not only contributes to our understanding of how certain acts are realized in context, but also how they contribute to the structure of the discourse. Finally, in the construction of text, speakers and writers must take into account the addressee.

A number of studies on the acquisition of tense and aspect by learners of a second language point to the hypothesis that narrative structure influences the distribution of tense/aspect forms in interlanguage. However, the studies have reported conflicting profiles of tense/aspect use. This study suggests that much of the variation that has been previously reported stems from the level of proficiency of the learners. This crosssectional study examines 37 written and oral narrative pairs produced in a film retell task by adult learners of English as a second language. The analysis approaches the texts from two perspectives, from the perspective of acquisition, taking narrative structure (specifically grounding) as an environment for acquisition of tense/aspect, and from the perspective of the narrative itself, characterizing the foreground and background by the tense/aspect forms used. The study finds a developmental pattern in the distribution of tense/aspect morphology with respect to narrative structure. These results permit the assimilation of earlier findings into a developmental sequence in the acquisition of the tense/aspect system.

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.
