This study examines the development of speech rhythm in second language (L2) learners of typologically different first languages (L1s) at different levels of proficiency. An empirical investigation of durational variation in L2 English productions by L1 Mandarin learners and L1 German learners compared to native control values in English and the learners’ L1s showed that the L1 groups followed comparable developmental paths in their acquisition of vocalic variability and accentual lengthening. However, the two L1 groups diverged in the proportion of vocalic materials in their L2 utterances, exhibiting L2 acquisition patterns that are consistent with direct transfer from the L1. The results support a multisystemic model of L2 rhythm acquisition in which the various linguistic-systemic properties that contribute to speech rhythm are acquired at different proficiency levels and depend on different acquisition processes with respect to L1 influence and universal effects. We conclude that theories of L2 phonology need to be able to accommodate the multisystemic nature of L2 prosodic acquisition. Additionally, L2 phonological acquisition theories, and SLA theories more generally, should take into account the nonuniform manner in which the various prosodic properties of the interlanguage reflect L1 transfer effects as well as universal constraints on acquisition.

Although many theoretical issues revolving around implicit and explicit knowledge in second language (L2) acquisition hinge on the ability to measure these two types of knowledge, few empirical studies have attempted to do so. However, R. Ellis (2005) did develop a battery of tests intended to provide relatively separate measures. This study aims to validate the use of Ellis’s test battery in an English as a foreign language context and to investigate the extent of Chinese first-year university students’ implicit and explicit L2 knowledge. Test scores loaded on two factors, as in R. Ellis (2005), thus demonstrating construct validity for the tests as measures of implicit and explicit knowledge in a population of Chinese university-level learners of English in a Chinese (as opposed to English as a second language) context. These learners were found to have higher scores on measures of explicit knowledge than on those of implicit knowledge because of the instruction they had received and their English learning environment.

This investigation of NS–NNS interaction in same- and cross-gender dyads on four information exchange tasks revealed that male and female NNSs made and received a comparable number of opportunities to request L2 input and modify interlanguage output during interaction with female NSs, but during interaction with male NSs, these opportunities were significantly lower for female than for male NNSs. In addition, more request-response exchanges were found on tasks in which either the NS or the NNS was given initial control over task-related information. Findings of the study were attributed to cultural similarities and differences in the interactional behaviors of the participants.

Voice onset time (VOT) was measured in the production of /t/ in the initial position of 60 English words spoken by native English (NE) speakers and native Spanish (NS) speakers who began learning English before or after the age of 21 years. The subjects rated the words for familiarity, age of acquisition, imageability, and relatedness to word(s) in the Spanish lexicon. The subjects in all three groups showed two well-known phonetic effects: They produced longer VOT values in the context of high than nonhigh vowels, and longer VOT in one- than in two-syllable words. As expected, the NS subjects who learned English prior to the age of 21 years judged the English words to be more familiar and more like a Spanish word than did the subjects who began learning English later in life. Also, many but not all of the NS subjects produced /t/ with shorter VOT values than did the NE subjects. However, regression analyses showed that none of the lexical factors mentioned above or the text frequency of the 60 English words examined affected the NS subjects' VOT values. Thus, variation in the accuracy with which NS subjects produce English /t/ must be accounted for by factors other than the lexical status of the words in which /t/ occurs.

This study investigates the effects of simplification, type of linguistic item, and second language experience on learners' intake of linguistic items contained in written input. Learners at two levels of language experience were exposed to one of the following four conditions: a simplified or unsimplified reading passage with the present perfect tense form or a simplified or unsimplified reading passage with the present subjunctive form. To measure learners' intake, a repeated-measures analysis of variance was performed on the raw scores obtained on a task consisting of a pre- and posttest. The tests were a multiple-choice recognition assessment task. Significant main effects were found for type of passage and language experience, and there was a significant interaction between type of passage and task. Results suggest that simplification does not have a facilitating effect on learners' intake and that learners at different levels demonstrate a different pattern of performance while internalizing written input. Implications for pedagogical written materials and future research are also discussed.

Findings from a longitudinal study of bilingual children acquiring Cantonese and English pose a challenge to the noun phrase accessibility hierarchy (NPAH; Keenan & Comrie, 1977), which predicts that object relatives should not be acquired before subject relatives. In the children's Cantonese, object relatives emerged earlier than or simultaneously with subject relatives, and in their English, prenominal relatives based on Cantonese emerged first, with object relatives followed by subject relatives. These findings are discussed in light of findings on the typology and acquisition of relative clauses (RCs) and the underlying processing motivations of the NPAH. Prenominal object relatives in the bilingual children's Cantonese and English have the same word order as main clauses and can be analyzed as internally headed RCs. The reconceptualization of RCs as attributive clauses (Comrie, 1998a, 1998b, 2002) is supported by children's early RCs lacking a strict grammatical relationship between the head noun and the predicate. Furthermore, as observed by Diessel and Tomasello (2000, 2005) for English, bilingual children's earliest RCs consist of isolated noun phrases (NPs). The early object relatives produced by bilingual children are therefore essentially NPs with the linear order of a main clause, resulting in a configuration that is conducive to early production.We thank Yasuhiro Shirai for organizing the workshop on second language acquisition of RCs at Cornell University in January 2006, where this paper was presented, as well as for his valuable comments on earlier versions of this paper.

This paper examines the sources of miscommunication in a videotaped tutoring session involving a native speaker of Korean and a native speaker of U.S. English. Analysis revealed an initial nonmutual interpretation of participant role and status. These divergent interpretations appear to have resulted from the Korean tutor's transfer of a Korean conversational routine, which he defined as involving polite speaker modesty, to the U.S. English context. The initial conflicting interpretations are maintained and solidified by additional mismatches in discourse management strategies, schema, and contextualization cues. The cumulative effect of these mismatches was the judgment on the part of each of the interlocutors that the other was uncooperative.

This experimental study on English, Spanish, and Turkish as second languages investigates the interaction of universal principles and L1 knowledge in interlanguage grammars by focusing on verbs that participate in the causative/inchoative alternation (such as break in English). These verbs have the same lexico-semantic composition, but differ crosslinguistically as to how they encode the alternation morphologically. Results of a picture judgment task show that, as in L1 acquisition, L2 learners of Turkish, Spanish, and English with different L1s rely on a universal mechanism when learning transitivity alternations. L1 influence plays a prominent role in the morphological realization of the alternation. These findings suggest that UG and L1 knowledge may not affect all linguistic domains in the same way at a given stage of development. It is proposed that transfer is subject to modularity in interlanguage grammars.

In a paired-associate learning (PAL) task, Dutch university students (n = 129) learned 20 English second language (L2) idioms either receptively or productively (i.e., L2-first language [L1] or L1-L2) and were tested in two directions (i.e., recognition or production) immediately after learning and 3 weeks later. Receptive and productive performance was affected by direction of learning. This finding parallels findings from PAL experiments on L2 individual-word learning. On a productive test, productive learners had a sizable advantage over receptive learners, whereas on recognition, receptive learners outperformed productive learners. Two idiom characteristics, imageability (capacity to evoke a mental image) and transparency (overlap between literal and figurative meaning), as assessed in a norming study by an independent sample (n = 80), qualified these findings. Indicating the importance of dual coding in idiom learning, imageability predicted performance, and receptive learning was particularly inefficient for low imageable idioms. Transparency was a weaker predictor of performance and only affected recognition.This study is based on the first author's MA research. We would like to thank the four anonymous SSLA reviewers for their helpful comments on this manuscript. Any errors or omissions remain our own.

This paper reports on a test of the validity of Pienemann's (1998) Processability Theory (PT). This theory predicts that certain morphological and syntactic phenomena are acquired in a fixed sequence. Three phenomena were chosen for this study: attributive adjective morphology, predicative adjective morphology, and subordinate clause syntax (placement of negation). These phenomena are located at successive developmental stages in the hierarchy predicted by PT. We test whether they actually do appear in this predicted hierarchical order in the L2 of Danish, Norwegian, and Swedish learners. The three languages mentioned are very closely related and have the same adjective morphology and subordinate clause syntax. We can, therefore, treat them as one language for the purposes of this study. Three analyses have been carried out: The first follows Pienemann's theory and is concerned only with syntactic levels; the second is a semantic analysis of the acquisition of number versus that of gender; the third analysis studies the various kinds of mismatches between the inflection of the noun, the controller, and the adjective. The results are the following: The first test supports PT as it has been described by Pienemann. The second analysis shows that there is an acquisitional hierarchy such that number is acquired before gender (in adjectives), and the mismatch analysis raises questions about the fundamental assumptions of the theory.

Building on the cognitive and interactive perspectives of task research, the cognition hypothesis states that increasing task complexity promotes greater interaction and feedback and thus facilitates second language (L2) development (Robinson, 2001b, 2007a). To date, very little research has explored this claim during learner-learner interactions in English as a foreign language (EFL) classroom contexts in which a task-based syllabus is implemented. The purpose of this study was to examine the effects of task complexity on the occurrence of interaction-driven learning opportunities and question development in such a classroom context. Korean university students (N = 191) from four intact English classes were randomly assigned to one comparison group and three experimental groups with various task-complexity levels (i.e., simple, +complex, and ++complex) based on Robinson’s framework. Their interactions were audiorecorded, and occurrences of learning opportunities, operationalized as language-related episodes (LREs), were identified. Question development was identified between pretest and posttests on the basis of the learners’ stage advancement using Pienemann and Johnston’s (1987) developmental sequence. Results indicated that more complex tasks promoted a greater number of LREs and particularly led to LREs targeting developmentally advanced question structures, which result in question development.

In this paper, various definitions of markedness are discussed, including the difference in the assumptions underlying psychological and linguistic approaches to markedness. It is proposed that if one adopts a definition derived from theories of language learnability, then the second language learner's prior linguistic experience may predispose him or her towards transferring marked structures from the first language to the second, contrary to usual assumptions in the literature that suggest that second language learners will avoid marked forms. To test this hypothesis, adult and child learners of French as a second language were tested using grammaticality judgment tasks on two marked structures, preposition stranding and the double object construction, which are grammatical in English but ungrammatical in French, to see if they would accept French versions of these structures. It was found that the second language learners did not accept preposition stranding in French but did accept the double object construction, suggesting that transfer takes place only with one of the two marked structures. In addition, the children took tests on these structures in their native language to see if they perceived them as in any sense psycholinguistically marked. Results show that they do not treat marked and unmarked structures differently in the native language. It is suggested that the concept of markedness may cover a range of phenomena that need to be further clarified and investigated.

In this paper the concept of “lexical unit” as proposed by Cruse (1986) is introduced in the context of L2 vocabulary learning to replace the rather vague notion of “word.” In the first part of the paper, this concept is defined in terms of lexical semantics and then applied to the L2 learning task. The second part describes two experimental studies in which the learning of different types of lexical units is examined. In the first study, totally new lexical units are compared with multiword items that are made up of familiar forms. In the second experiment, different types of new senses of familiar forms are compared. Both studies underscore the importance of knowledge of form—but not of previously learned meaning—for the learning of new meanings for familiar forms.

If one would ask me as a regular, though not systematic reader in applied linguistics to mention a major theoretical issue in this field of study, I would choose for the controversy about “behavioristic” audiolingual learning versus “mentalistic” cognitive code learning. This dichotomy is apparent in many theoretical papers, and starting point of various research programs.

This article reports an empirical study in which we explored the role played by two forms of feedback—error correction and model texts—on child English as a foreign language learners’ reported noticing and written output. The study was carried out with 11- and 12-year-old children placed in proficiency-matched pairs who engaged in a three-stage collaborative writing task involving (a) spontaneous noticing of linguistic problems while composing, (b) comparison of their texts with the feedback provided, and (c) rewriting of their original output. Results indicate that although the children noticed and later incorporated mainly lexical features into their output, gains in the linguistic acceptability and comprehensibility of their revised texts showed an advantage for error correction over models. Learners in the error correction condition reported more noticing of grammar at the comparison stage, which later emerged in their revisions. The potential effects of both feedback strategies on children’s reported noticing and output production are discussed, and conclusions are drawn for the role of feedback in children’s classroom second language acquisition.

The purpose of the present paper is to examine the hypothesis that there are fundamental differences between using language in different situations or for different purposes, and that these differences may be accounted for in terms of the requirement of the task to be solved on the basis of knowledge represented in a particular way.

The literature exploring the executive function correlates of bilingualism is vast, but to date, few studies have concentrated on children, for whom the bilingual advantage appears even more inconsistent than for adults. We investigate a highly heterogeneous group of children (in terms of bilingual experience and socioeconomic status) and identify the critical threshold of bilingual experience from which an advantage can be observed at group level. The modeling methods adopted allow the use of fine-grained, continuous factors for age and socioeconomic status, thereby effectively controlling for their effect and isolating the specific effect of bilingual experience. We pioneer the use of Cox Proportional Hazard regression to analyze performance in the Simon task. This allows the modeling of all data points without transformation or outlier removal, and captures both accuracy and reaction time within the same analysis, while being able to handle multiple predictor variables.

It is commonly believed that second language (L2) acquisition of lexical tones presents a major challenge for learners from nontonal language backgrounds. This belief is somewhat at odds with research that consistently shows beginning learners making quick gains through focused tone training, as well as research showing advanced learners achieving near-native performance in tone identification tasks. However, other long-term difficulties related to L2 tone perception may persist, given the additional demands of word recognition and the effects of context. In the current study, we used behavioral and event-related potential (ERP) experiments to test whether perception of Mandarin tones is difficult for advanced L2 learners in isolated syllables, disyllabic words in isolation, and disyllabic words in sentences. Stimuli were more naturalistic and challenging than in previous research. While L2 learners excelled at tone identification in isolated syllables, they performed with very low accuracy in rejecting disyllabic tonal nonwords in isolation and in sentences. We also report ERP data from critical mismatching words in sentences; while L2 listeners showed no significant differences in responses in any condition, trends were not inconsistent with the overall pattern in behavioral results of less sensitivity to tone mismatches than to semantic or segmental mismatches. We interpret these results as evidence that Mandarin tones are in fact difficult for advanced L2 learners. However, the difficulty is not due primarily to an inability to perceive tones phonetically, but instead is driven by the need to process tones lexically, especially in multisyllable words.

This study of five native speakers of Korean investigates the role of universals in their acquisition of English obstruent voicing contrasts. The data were gathered from a passage and a word list containing voiced and voiceless obstruents in initial, medial, and final word positions. Results reflected principles of markedness universals of L1 acquisition and adult natural languages, suggesting that interlanguage systems behave according to universals of natural languages.
