The present cross-linguistic study deals with the relevance of principles of information organization in adult second language acquisition. It looks at typological features of information structure that allow speakers to organize and shape the flow of information when carrying out complex tasks, such as giving a description, and pinpoints factors that lead to the selection of linguistic form. At the focus of our attention are means used in reference introduction, such as existential and locational constructions, the morphosyntactic forms of expressions applied in reference maintenance, and word order. The cross-linguistic comparison shows that the options found in the expression of these functions in German, English, and Romance languages (French, Italian, and Spanish) follow distinct patterns in that the linguistic means used reflect unifying principles of a typological nature. These principles are perspective driven and are associated with patterns of grammaticization. Structures in language that reflect core principles in information organization may be difficult to acquire because learners have to recognize clusters of form-function relations that range over different domains. The nature of the analyses required is described for learners of German with English and Spanish as their source languages. The interlanguages (ILs) of these speakers show a high degree of compatibility with German in formal syntactic terms and are near native in many respects, but the levels at which the IL and target language diverge can be linked to fundamental principles of organization underlying information structure. Although the stage of acquisition is advanced, the languages still retain core principles in information structure typical of those found for English and Romance languages.

Research investigating incidental vocabulary learning through listening to songs has primarily relied on participant’s self-report surveys on listening behaviors and its relationship with their vocabulary knowledge (Kuppens, 2010). Only one experimental study has investigated vocabulary learning gains from listening to songs (Medina, 1993). From the results, the researcher concluded that learning does occur from listening to songs. However, the learning gains were not provided. The present study investigated incidental learning of three vocabulary knowledge dimensions (spoken-form recognition, form-meaning connection, and collocation recognition) through listening to two songs. The effects of repeated listening to a single song (one, three, or five times) and the relationship between frequency of exposure to the targeted vocabulary items and learning gains were also explored. The results indicated that (a) listening to songs contributed to vocabulary learning, (b) repeated listening had a positive effect on vocabulary gains, and (c) frequency of exposure positively affected learning gains.

Researchers have claimed that recasts might be ambiguous as feedback. Because recasts serve a dual function, as both feedback and conversational response, learners might not always interpret them as feedback (e.g., Lyster & Ranta, 1997). This study explores how learners interpret recasts they notice (as responses to content, negative evidence, positive evidence, or a combination of negative and positive evidence) and how recast features (linguistic targets, length, number of changes) might affect their interpretations. Forty-nine learners of Japanese engaged in task-based activities during which they received recasts of morphosyntactic and lexical errors. When learners noticed recasts, they occasionally interpreted them as responses to content, particularly when recasts were long and substantially different from their problematic utterances. In contrast, learners were significantly more likely to attend to the linguistic evidence in recasts when these were short and closely resembled the original utterances. These patterns were generally observed for both morphosyntactic and lexical recasts. Results suggest that length and number of changes might, in part, determine the explicitness of recasts as feedback and thus affect learners' abilities to interpret them as such.I am grateful to Alison Mackey, Helen Carpenter, and Ana-Maria Nuevo for their insightful suggestions on an earlier version of this article.

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 study examined an integrated process model of second language motivation based on the framework of self-determination theory (SDT). Specifically, this research investigated the extent to which satisfying basic psychological needs (BPN) are related to SDT orientations and, in turn, to the effort expended and how these factors relate collectively to vocabulary knowledge. Revised scales assessing students’ BPN (the Basic Psychological Needs of Second Language Scale) and SDT orientations (the Self-Determination Theory of Second Language Scale) were considered and tested using a higher-order confirmatory factor analysis solution. The results of the structural model showed that BPN were only directly related to vocabulary knowledge, which indicated their direct importance for the attainment of the vocabulary. No other indirect effects through SDT orientations or effort were identified. Nonetheless, SDT orientations were both directly and indirectly linked to vocabulary knowledge over and above the role of expended effort. The results elucidated motivational pathways that yielded pedagogical implications for language learning.

Interaction research that has investigated the relationship between language production and second language (L2) development has largely focused on learners' immediate responses to interactional feedback. However, other speech production processes might help account for the beneficial relationship between interaction and L2 development. The current study examines whether syntactic priming—the tendency to produce a syntactic structure encountered in the recent discourse—is associated with English as a second language (ESL) question development. The participants were intermediate-level Thai learners of English (N = 46) at a large public university in northern Thailand. In two 20-min sessions, the participants carried out communicative activities with a more advanced L2 English interlocutor who had been scripted with developmentally advanced question forms. They also completed an oral pretest and two posttests that consisted of activities similar to those carried out during the treatment sessions. The results indicated that participants who evidenced high levels of syntactic priming were likely to advance to a higher stage in the developmental sequence of ESL question formation.

This review examines whether similarity between the first language (L1) and second language (L2) influences the (morpho)syntactic processing of the L2, using both neural location and temporal processing information. Results from functional magnetic resonance imaging (fMRI) and event-related potential (ERP) studies show that nonnative speakers can exhibit nativelike online L2 (morpho)syntactic processing behavior and neural patterns. These findings are contrary to predictions of the shallow structure hypothesis for syntactic processing (Clahsen & Felser, 2006a, 2006b). The data are in line with predictions of the (morpho)syntactic domain of the unified competition model of L2 acquisition (MacWhinney, 2005): Differences in L2 processing as compared to the L1 (or to native speakers of the L2) were generally associated with constructions that were crosslinguistically dissimilar or unique to the L2. The processing of crosslinguistically similar constructions generally produced no differences in brain activity between the L1 and L2. Overall, the available data suggest that cross-language similarity is an important factor that influences L2 (morpho)syntactic processing.

In this paper we address the need for replication studies in the field of second language acquisition and discuss the problems surrounding standards of reporting research. A particular focus is on the level of detail necessary for replication to take place. The lack of uniform standards is noted with specific examples of problematic reporting taken from descriptions of second language learners' proficiency levels and measures of linguistic accuracy in second language writing research. We propose ways that we believe will lead to more thorough reporting of research and that will therefore allow others to engage in replication.

In this response to Ellis's target article on frequency in language processing, language use, and language acquisition, we argue in favor of a role for frequency in several areas of second language acquisition, including interactional input and output and speech processing. We also discuss areas where second language acquisition appears to proceed along its own route and at its own pace regardless of the frequency of the input, as well as areas where input is infrequent but acquisition appears to be unimpeded. Our response is intended to highlight the complexity of the task of deciphering the role and importance of frequency.

This study explores the question of whether native and nonnative listeners, some familiar with the language and some not, differ in their accent ratings of native speakers (NSs) and nonnative speakers (NNSs). Although a few studies have employed native and nonnative judges to evaluate native and nonnative speech, the present study is perhaps the first to include nonnative judges who were unfamiliar with the language they were judging. This study compares accent ratings of four different groups listening to Brazilian Portuguese spoken by NSs and NNSs. The 25 speakers of Portuguese were 5 NSs and 20 NNSs who were NSs of American English. The four listening groups were (a) Brazilian Portuguese listeners, (b) American English listeners with Portuguese experience, (c) American English listeners without Portuguese experience, and (d) English as a second language listeners without Portuguese experience. Although there were some differences, the results show striking similarities across groups, suggesting that listeners' first and second languages do not strongly affect ratings of foreign accents. The study also has implications for the critical period hypothesis because it raises the possibility that there are salient universal features of nonnative speech.

The present study addresses the reactivity of two types of verbal protocols in SLA research. It expands on the work of Leow and Morgan-Short (2004), who found nonmetalinguistic verbalization during a second-language reading task to be nonreactive for beginning learners' text comprehension, intake, and production of the targeted morphological form. The present study investigated the reactivity of both metalinguistic and nonmetalinguistic protocols, using a syntactic structure and advanced language learners of Spanish. Results indicated that neither type of verbalization significantly affected text comprehension or written production of old or new exemplars of the targeted structure when compared to a control group, although metalinguistic verbalization appeared to cause a significant decrease in text comprehension over nonmetalinguistic verbalization. Furthermore, both types of verbalization significantly increased the amount of time on task.

This study examines the acquisition of the featural constraints on clitic and null distribution in Spanish among simultaneous and sequential Chinese-Spanish bilinguals from Peru. A truth value judgment task targeted the referential meaning of null objects in a negation context. Objects were elicited via two clitic elicitation tasks that targeted anaphoric contexts and left-dislocated topics. An acceptability task tested sensitivity to left-dislocated object drop. Although simultaneous bilinguals were mostly undistinguishable from monolinguals, the late learners differed from both of these groups across tasks. Age of arrival led to different outcomes, with late learners showing more deficits than the child learners. Late learners avoided using clitics and relied on lexical and null objects. Residual transfer effects were observed among the child learners in the form of insensitivity to the features that serve as the basis for null argument identification and clitic deficits in production. It is also argued that transfer persists despite early and intense exposure to the second language in a natural environment because of the existence of an unmarked argument identification option in the first language.

This study examines the role of environment in the development of pragmatic comprehension. It tracks two groups of Japanese students of English: 60 students in a college in Japan (English as a foreign language [EFL] learners) and 57 students in a college in the United States (English as a second language [ESL] learners). The learners completed a computerized listening task that measured their ability to comprehend two types of implied meaning: indirect refusals (k = 24) and indirect opinions (k = 24). The task was given to each group twice, before and after the students received approximately 120–130 hr of classroom instruction. Comprehension was analyzed for accuracy (scores) and speed (average time taken to answer each item correctly). Results showed that, in both learner groups, accuracy and comprehension speed improved significantly over time. For the EFL group, the magnitude of effect was much less for speed than for accuracy. In contrast, ESL learners showed significant improvement in comprehension speed, with a sizable effect size, but only marginal improvement in accuracy.

Meta-analytic research suggests an edge of explicit over implicit instruction for the development of complex L2 grammatical structures, but the jury is still out as to which type of explicit instruction—deductive or inductive, where rules are respectively provided or elicited—proves more effective. Avoiding this dichotomy, accumulating research shows superior results for guided induction, in which teachers help learners co-construct rules by directing their attention to relevant aspects in the input and asking guiding questions. However, no study has jointly investigated the effects of guided induction on both learning outcomes and processes, or whether guided induction can prove effective outside classroom settings where teacher mediation is not possible. In this study, which targeted the complex Spanish gustar structures, 70 English-speaking learners of beginning Spanish received either guided induction via a videogame, deductive instruction in a traditional classroom setting, or no instruction. Learning outcomes were measured via one receptive and two controlled production tasks (oral and written) with old and new items. Results revealed that while both instruction groups improved across time, outperforming the control group, the guided induction group achieved higher learning outcomes on all productive posttests (except immediate oral production) and experienced greater retention. Additionally, the think-aloud protocols of the guided induction group revealed high levels of awareness of the L2 structure and a conspicuous activation of recently learned knowledge, which are posited to have contributed to this group’s superior performance. These findings thus illustrate, quantitatively and qualitatively, the potential of guided induction for the development of complex L2 grammar in online learning environments.

This paper illustrates the advantages of laboratory research into SLA by describing two studies of acquisition of second language syntax. The first addresses the question of whether human morphological abilities can be understood in terms of associative processes or whether it is necessary to postulate rule-based symbol processing systems underlying these skills. We demonstrate that acquisition of L2 morphology shows frequency effects for both regular and irregular forms and that the acquisition course of learners' accuracy and reaction time can be accurately simulated by connectionist systems. The second concerns a bootstrapping account of SLA whereby processes of chunking in phonological memory underpin the acquisition of long-term memory for utterances and abstractions of grammatical regularities. It shows that phonological short-term memory is particularly important in the acquisition of long-distance dependencies. In both cases, it is argued that these aspects of SLA reflect associative learning processes. When SLA research is properly focused on acquisition, laboratory research allows investigation of the learners' exposure to evidence, their processes of perception and learning, and their resultant language representations.

This study investigated whether the role of working memory capacity varies over the course of second language (L2) morphosyntactic development. Eighty-seven beginning, intermediate, and advanced university L2 Spanish learners completed two nonverbal tasks measuring executive function (EF) and phonological working memory (PWM) in their native language (English) and two tasks measuring knowledge of ten grammatical structures in Spanish at three points during and after a semester of instruction. Robust relationships between both working memory components, especially PWM, and L2 performance, emerged only for lower level learners, particularly at the start of instruction and 3.5 months later. Findings demonstrate that the facilitative effects of cognitive ability appear to lessen with increasing L2 proficiency and empirically support a developmental perspective of L2 learning.

This study investigated the effectiveness of providing L1 explicit information (EI) with practice for making more accurate and faster interpretations of L2 French Imparfait (IMP). Two treatments were investigated: (a) “L2-only,” providing EI about the L2 with L2 interpretation practice, and (b) “L2+L1,” providing the exact same L2-only treatment and including EI about the L1 (English) with practice interpreting L1 features that are equivalent to the IMP. Fifty L2 French learners were randomly assigned to either L2-only, L2+L1, or a control group. Online (self-paced reading) and offline (context-sentence matching) measures from pretest, posttest, and delayed posttests showed that providing additional L1 EI and practice improved not only offline L2 accuracy, but also the speed of online L2 processing. To our knowledge, this makes original and significant contributions about the nature of EI with practice and the role of the L1 (Tolentino & Tokowicz, 2014), and it extends a recent line of research examining EI effects in online sentence processing (Andringa & Curcic, 2015).

This paper reports the results of a study of the intonation of 18 Mandarin Chinese speakers lecturing in English. As a basis for the study, it is proposed that intonation be considered a grammar of cohesion in English discourse: Drawing from the intonational model of Pierrehumbert and Hirschberg (1990), it is argued that discrete morphemes of intonation correspond to the categories of cohesion in Halliday and Hasan's (1976) typology. The study investigated the hypothesis that the nonnative speakers who were able to use the intonation system of English most effectively would score higher on a global language test. Using a Computerized Speech Lab to measure pitch, four aspects of intonation were averaged for each speaker: (a) the pitch difference between newly introduced content words and function words, (b) the use of high pitch at phrase boundaries to link related constituents, (c) the use of pitch to distinguish contrasting items from given items, and (d) the paratone or increase in pitch range at rhetorical junctures to signal topic shift. These four measures were chosen for their contribution to the cohesion of the lectures. Multiple regression analysis indicates that the fourth intonation variable, the paratone, was a significant predictor of these subjects' English test scores. Examples are given of the other variables in context from both low- and high-scoring speakers. It is emphasized that intonation is not only a stylistic component of accent but also a meaning-bearing grammatical system.

To what extent do second language (L2) learners benefit from instruction that includes corrective feedback (CF) on L2 speech perception? This article addresses this question by reporting the results of a classroom-based experimental study conducted with 32 young adult Korean learners of English. An instruction-only group and an instruction + CF group were exposed to five 1-hr form-focused lessons that drew learners’ attention to the nonnative phonemic contrast /i/-/ɪ/, but only the instruction + CF group was given relevant feedback. Forced-choice identification tasks were completed by participants in a pretest, an immediate posttest, and a delayed posttest. The two groups showed similar accuracy on the pretest; however, the instruction + CF group outperformed the instruction-only group on the immediate and delayed posttests as well as on unfamiliar words. The significant predictors for these differences turned out to be perceptual accuracy vis-à-vis /ɪ/-natural and /ɪ/-synthesized sounds. These findings are discussed in terms of the pivotal role played by CF in developing accuracy in L2 speech perception.

This study investigates the interface between speech and gesture in second language (L2) narration within Slobin's (2003) thinking-for-speaking (TFS) framework as well as with respect to McNeill's (1992, 2005) growth point (GP) hypothesis. Specifically, our interest is in whether speakers shift from a first language (L1) to a L2 TFS pattern as manifested in the GP of narrations they produce. The data are drawn from the narrations of an animated cartoon story produced by advanced L2 speakers of Korean (L1 English) and L2 speakers of English (L1 Korean). Korean is a verb-framed language (Talmy, 2000) that conflates path of motion on the verb and expresses manner, if at all, through separate lexical items, onomatopoeia, or gesture alone. English is a satellite-framed language (Talmy, 2000) that encodes manner on verbs, expresses path through satellite phrases, and synchronizes manner-path conflated gestures with manner verbs when manner is in focus. The typological difference between the languages presents significant challenges for the L2 speakers, who, despite their high level of proficiency in their respective L2s, appear to retain their L1 TFS patterns.
