ABSTRACTLanguage development is frequently characterized as a process where learning proceeds implicitly, that is, incidentally and in absence of awareness of what was learned. This article reports the results of two experiments that investigated whether second language acquisition can also result in implicit knowledge. Adult learners were trained on an artificial language under incidental learning conditions and then tested by means of grammaticality judgments and subjective measures of awareness. The results indicate that incidental exposure to second language syntax can result in unconscious knowledge, which suggests that at least some of the learning in this experiment was implicit. At the same time, however, it was also found that conscious (but unverbalizable) knowledge was clearly linked to improved performance in the grammaticality judgment task.

ABSTRACTThis study set out to test the degree to which second language inflectional morphology can be acquired as a result of incidental exposure and whether the resulting knowledge is implicit (unconscious) or explicit (conscious) in nature. Participants were exposed to an artificial language system based on Czech morphology under incidental learning conditions. In the testing phase, a grammaticality judgment test was utilized to assess learning. In addition, subjective measures of awareness and retrospective verbal reports were used to measure whether the acquired knowledge was conscious or not. The results of the experiment indicate that participants can rapidly develop knowledge of second language inflectional morphology under incidental learning conditions in the absence of verbalizable rule knowledge.

AbstractImplicit and explicit knowledge use in second language acquisition has been rigorously researched in areas such as syntax, however our understanding of how these knowledge constructs affect learner pragmatics is not well understood. Through an interlanguage pragmatic perspective we aim to understand how implicit and explicit knowledge intertwines with pragmalinguistic and sociopragmatic competence. This is investigated by testing for L1 politeness transfer in Korean learners of French regarding their acquisition of tu and vous, which provides a new perspective as past research focuses on Anglophone learners. By triangulating data from two test types, results show that the learners have difficulty with vous but not tu, attributed to negative language transfer of L1 politeness values. Moreover, learner variation of tu/vous use can be linked to the explicit/implicit status of their pragmalinguistic and sociopragmatic knowledge, showing that the implicitization of their sociopragmatic knowledge is a challenging hurdle towards native-like tu/vous use.

This article reviews studies in second language classroom research from a cross-theoretic perspective, arguing that the classroom holds the potential for bringing together researchers from opposing theoretical orientations. It shows how generative and general cognitive approaches share a view of language that implicates both implicit and explicit knowledge, and that holds a bias towards implicit knowledge. Arguing that it is implicit knowledge that should be the object of research, it proposes that classroom research would benefit from incorporating insights from a generative understanding of language. Specifically, there is a need for a more nuanced view of the complexity of language in terms of linguistic domain, and the interaction between those domains. Generative second language acquisition research that shows developmental differences in terms of both linguistic domain and interface is reviewed. The core argument is a call for more attention to the ‘what’ of language development in classroom research and, by implication, teaching practice. As such, the language classroom is seen to offer potential for research that goes beyond paradigm to address both the ‘what’ and the ‘how’ of language development.

This article takes a critical look at grammaticality judgment tasks in second language acquisition research. It begins by examining the theoretical assumptions that underlie grammaticality judgment tasks, pointing out that previous studies have reported considerable differences between the results obtained from grammaticality judgment tasks and from other, production-oriented tasks. A description of the design features of grammaticality judgment tasks that have been used to date is then provided. There follows an account of a small-scale study designed to investigate the nature of learner judgments. Twenty-one adult advanced Chinese learners of English were asked to judge sentences designed to test their knowledge of dative alternation. The results indicated that the learners rarely used the “not sure” option in the test. Eight of these subjects were then administered a reduced version of the original test as a think-aloud task 1 week later. The results showed that these learners were inconsistent in 22.5% of their judgments. The think-aloud protocols showed that they resorted to a variety of strategies in making judgments. The article concludes by arguing that grammaticality judgment tasks elicit a particular kind of performance that needs to be understood much more thoroughly before it is used as a basis for investigating second language acquisition.

AbstractResearch on age and second language acquisition (L2A) is vast, but inconclusive. Such research has mainly been motivated by the Critical Period Hypothesis (CPH), which postulates that language acquisition becomes extremely difficult after the onset of puberty. Also, there is a lack of research on age and third/additional language (L3/Ln) learning. To fill this gap, this article examines differences in morphosyntactic knowledge between early and late learners of English as a L3/Ln. In this study, ‘early’ and ‘late’ learners are those participants first exposed to English as a medium of instruction (MOI) in 1st and 11th grades, respectively. Participants’ morphosyntactic knowledge was assessed based on two tasks: (a) a Grammaticality Judgment Task (GJT) and (b) an editing task. Three hundred and thirty five undergraduate and graduate students from two universities in Pakistan voluntarily participated in the research. Results of the group comparisons showed no statistically significant differences between early and late learners on the GJT; however, on the editing task, a modest but significant difference was observed between the two groups, with late learners scoring higher. This finding contradicts the predictions of the CPH.

Second language learning outcomes are highly variable, due to a variety of factors, including individual differences, exposure conditions, and linguistic complexity. However, exactly how these factors interact to influence language learning is unknown. This article examines the relationship between these three variables in language learners.Native English speakers were exposed to an artificial language containing three sentence patterns of varying linguistic complexity. They were randomly assigned to two groups—incidental and instructed—designed to promote the acquisition of implicit and explicit knowledge, respectively. Learning was assessed with a grammaticality judgment task, and subjective measures of awareness were used to measure whether exposure had resulted in implicit or explicit knowledge. Participants also completed cognitive tests.Awareness measures demonstrated that learners in the incidental group relied more on implicit knowledge, whereas learners in the instructed group relied more on explicit knowledge. Overall, exposure condition was the most significant predictor of performance on the grammaticality judgment task, with learners in the instructed group outperforming those in the incidental group. Performance on a procedural learning task accounted for additional variance. When outcomes were analyzed according to linguistic complexity, exposure condition was the most significant predictor for two syntactic patterns, but it was not a predictor for the most complex sentence group; instead, procedural learning ability was.

AbstractThis article reports on a small study investigating whether teaching second language learners the long-distance (LD) properties of the Japanese reflexive zibun ‘self leads to acquisition of its subject-oriented status. The study involved low intermediate level learners of Japanese who were instructed on zibun over a four-week period. The focus of the instruction was that the reflexive zibun can take long-distance antecedents. At the same time, subjects were never taught that the antecedent must be a subject. Subjects were tested using a truth-value judgment task. Results show that the learners initially rejected LD binding; they showed a significant increase in acceptance of LD antecedents after the teaching intervention. Analyses of individual learners show that about half of them successfully acquired the relevant properties of zibun. With one exception, learners did not generalize from their instruction to assume that “anything goes” as far as antecedents for zibun are concerned. Rather, they acquired grammars of reflexive binding that fall within the range permitted by Universal Grammar.
