This study examined the linguistic dimensions of comprehensibility and perceived fluency in the context of L2 argumentative speech elicited from 40 Japanese-speaking learners of English. Their speaking performance was judged by 10 inexperienced native speakers of English for comprehensibility and perceived fluency, and was also objectively analyzed in terms of complexity, accuracy, and fluency as well as pronunciation and discourse features. The results showed that comprehensibility and fluency judgments strongly correlated with each other and that native listeners were significantly more severe when they judged fluency. Furthermore, multiple regression analyses revealed that both constructs were commonly associated with a set of underlying linguistic dimensions (grammatical accuracy, breakdown fluency, and pronunciation). However, comprehensibility was best predicted by articulation rate (speed fluency) whereas perceived fluency was most strongly associated with the frequency of mid-clause pauses (breakdown fluency).

This paper reports on a study designed to investigate psychological factors that affect access to metalinguistic knowledge in second language (L2) production. Based on previous cognitive and psycholinguistic research, it was hypothesized that real-time access to metalinguistic knowledge would be largely determined by three interacting factors: attention to form, processing automaticity, and linguistic prototypicality (i.e., whether a rule concerns a central or peripheral use of a target structure). The subjects were 64 adult Chinese learners of English. A verbalization task was used to assess their metalinguistic knowledge about 12 target uses, and a judgment test was administered to determine the relative prototypicality of these uses. Attention to form was operationalized by two consciousness-raising tasks and by time pressure. Analyses of the subjects' output on writing and error-correction tasks revealed significantly greater grammatical accuracy for more prototypical uses and on tasks that allowed more attention to form. There was also a significant interaction between prototypicality and attention to form, suggesting the influence of processing automaticity. These results are taken as evidence that there are major psychological constraints on the utility of metalinguistic knowledge in L2 performance.

This paper provides evidence from a study of ESL speakers that cross-language transfer effects interact, sometimes in very subtle ways, with developmental effects in the construction of L2 syllable structures. It extends Broselow and Finer's (1991) proposal for the Minimal Sonority Distance Parameter-Setting (MSD) model in L2 syllables by (a) adding evidence from a language that unambiguously exhibits transfer in complex onsets and (b) examining syllable codas to see whether the MSD parameter can be extended to account for the distribution of error patterns there, as well. The results of the study generally support the predictions that the MSD model makes for consonant cluster difficulty in specific syllable positions; however, it does not make predictions about the patterns that are found in learner error types. We argue that optimality theory (Prince & Smolensky, 1993) provides a more explicit account of the interactions between transfer and developmental effects in L2 syllables, allowing us to interpret within a singular grammatical framework not only why learners have difficulty with specific ESL structures but also how they resolve it.

This paper argues that the brain is the seat of cognition, that cognitive processes are neural processes, and that, in the brain, affect and cognition are distinguishable but inseparable. This perspective allows a reconceptualization of the affective filter in terms of the brain's stimulus appraisal system, which interacts with cognition to promote or inhibit second language acquisition. A research strategy is proposed for investigating these ideas.

We report the results of a 2-year longitudinal comparison of grade 3 and grade 4 English-as-a-second-language learners in an experimental, comprehension-based program and those in a regular (i.e., more typical) language learning program. The goal was to examine the extent to which sustained, long-term comprehension practice in both listening and reading—in the virtual absence of any speaking—can help develop learners’ second language (L2) pronunciation. We analyzed learners’ sentences from an elicited imitation task using several accuracy and fluency measures as well as listener ratings of accentedness, comprehensibility, and fluency. We found no differences between the two programs at the end of year 1. However, at the end of year 2, there were some differences—namely, in the listener ratings of fluency and comprehensibility—that favored learners in the regular program. These findings highlight the beneficial effects of comprehension practice for the development of L2 pronunciation but also point to some potential limits of this practice.

The study reported in this paper examined four groups of readers (L2-Intermediate, L2-Advanced, L1-Japanese, and L1-English) when they processed and recalled two passages that varied in degree of causal coherence (Trabasso & van den Broek, 1985). Concurrent verbal reports and recall data were collected. It was found that L1 readers used much of their attention for higher level processes such as the generation of inferences and general knowledge associations. They processed the high- and low-coherence texts differently, generating more elaborations for low-coherence texts than for high-coherence texts. Furthermore, L1 readers generated backward inferences according to the text's causal structure and recalled events with many causal connections more frequently than events with few connections. These findings confirm L1 research findings (Fletcher & Bloom, 1988; Goldman & Varnhargen, 1986; Graesser & Clark, 1985; Singer, 1995; Trabasso & van den Broek, 1985; van den Broek, 1994). On the other hand, L2 readers paid more attention to lower level processes and did not process differently between the high- and low-coherence texts. L2-Advanced readers generated both backward and forward inferences during reading, whereas L2-lntermediate readers did not. Although L2-Advanced readers' generation of backward inferences did not correspond to the text's causal structure, their second recall indicated they were sensitive to it. A closer look at the data suggests that there were some delays in lower level processes such as understanding words and sentences, as well as resolution of anaphoric relations by these readers.

This study offers methodological synergy in the examination of factorial structure in second language (L2) research. It illustrates the effectiveness and flexibility of the recently developed exploratory structural equation modeling (ESEM) method, which integrates the advantages of exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) into one complete measurement model. Two sets of data were collected using the L2 Passion Scale, which measures a dualistic model of passion. Study 1 participants were 220 L2 students. A comparison was made between the CFA and the ESEM models. The results demonstrated the superiority of the ESEM method relative to CFA in terms of better goodness-of-fit indices and realistic correlated factors. These results were replicated in another sample of 272 L2 students, providing support for the predictive validity using a structural ESEM model. Guidelines are provided and Mplus syntax files (codes) are included to help analysts apply the methods. We also make the data available publicly. Overall, this research demonstrated the usefulness of ESEM for examining the construct, discriminant, and convergent validity of L2 scales over CFA.

Evidence of learning following incidental exposure has been found for aspects of nonnative syntax in adults (Rebuschat & Williams, 2006, 2012; Williams & Kuribara, 2008). However, little research has tested delayed effects of learning under an incidental condition or moved beyond word order. This study investigated learning of third language (L3) morphosyntax (word order and case marking) under an incidental exposure condition. Participants were second language Spanish learners exposed auditorily to a semiartificial language, Japlish, during a semantic plausibility judgment task. Performance following exposure to L3 Japlish was assessed with acceptability judgment and picture-matching tasks that were administered immediately after exposure and 2 weeks later. Results on immediate tests showed a significant learning effect on acceptability judgment but none for picture matching. At delayed testing, results showed maintenance of the learning effect on acceptability judgment and significantly improved performance on picture matching. Results additionally showed that many of the learners arrived at the correct Japlish word-order rule; fewer did so for case marking. Follow-up analyses indicated that this rule knowledge, as measured by debriefing information, was important for performance on both assessment tasks, particularly at delayed testing. The results suggest that learning of L3 structures can take place following incidental exposure, that such learning is durable and undergoes improvement, and that development of reportable rule knowledge may also play an important role.

We revisit morpheme studies to evaluate the long-standing claim for a universal order of acquisition. We investigate the L2 acquisition order of six English grammatical morphemes by learners from seven L1 groups across five proficiency levels. Data are drawn from approximately 10,000 written exam scripts from the Cambridge Learner Corpus. The study establishes clear L1 influence on the absolute accuracy of morphemes and their acquisition order, therefore challenging the widely held view that there is a universal order of acquisition of L2 morphemes. Moreover, we find that L1 influence is morpheme specific, with morphemes encoding language-specific concepts most vulnerable to L1 influence.

The present study brings together methods of extensive reading studies and eye-movement research to track the cognitive effects of exposure frequency on vocabulary processing and learning. Forty-two advanced second language learners of English read a stage 1 graded reader, Goodbye Mr. Hollywood, on a computer screen while their eye movements were recorded. The eye-tracking task was followed by comprehension questions and vocabulary posttests. Target vocabulary consisted of 20 pseudo words and 20 known words with a range of repetition from 1 to 30. Eye-movement data showed that readers spent more time on pseudo words than on familiar words and that fixation times decreased across encounters with more attention given to target words on early encounters. Repeated exposure supported form recognition but was not as significant for meaning recall and recognition. Total times spent on each encounter was positively associated with learning success in all vocabulary measures. The amount of attention, as reflected in total reading times on each pseudo word, positively predicted learning outcomes above and beyond the number of encounters. Results of the study add a cognitive dimension to the concept of engagement in lexical learning in the process of incidental learning from second language reading.

This paper examines the effects of a first language (L1 ) orthographic system on second language (L2) word recognition strategies. Lexical judgment tests using Japanese kana (a syllabic script consisting of hiragana and katakana) were given to native English and native Chinese learners of Japanese. The visual familiarity and length in test words were controlled to examine the involvement of phonological or visual coding in word recognition strategies. The responses of the English and Chinese subjects were compared on the basis of observed reaction time. The results indicated that (a) Chinese subjects relied more on the visual information in L2 Japanese kana words than did English subjects and (b) English subjects utilized the phonological information in Japanese kana words more than did Chinese subjects. Accordingly, these findings demonstrate that native speakers of English and Chinese utilize different word recognition strategies due to L1 orthographic characteristics, and such L1 word recognition strategies are transferred into L2 Japanese kana word recognition.

This article has two main goals. The first is to summarize and comment on the current state of affairs of generative approaches to SLA (GenSLA), 35 years into its history. This discussion brings the readership of SSLA up to date on the questions driving GenSLA agendas and clears up misconceptions about what GenSLA does and does not endeavor to explain. We engage key questions, debates, and shifts within GenSLA such as focusing on the deterministic role of input in language acquisition, as well as expanding the inquiry to new populations and empirical methodologies and technologies used. The second goal is to highlight the place of GenSLA in the broader field of SLA. We argue that various theories of SLA are needed, showing that many existing SLA paradigms are much less mutually exclusive than commonly believed (cf. Rothman & VanPatten, 2013; Slabakova, Leal, & Liskin-Gasparro, 2014, 2015; VanPatten & Rothman, 2014)—especially considering their different foci and research questions.

Although researchers argue that studying semantically related words simultaneously (semantic clustering) inhibits vocabulary acquisition, recent studies have yielded inconsistent results. This study examined the effects of semantic clustering while addressing the limitations of previous studies (e.g., confounding of semantic relatedness with other lexical variables). Furthermore, the study investigated the effects of spacing because spacing might facilitate the learning of semantically related items by alleviating interference. In this study, 133 Japanese university students studied 48 English-Japanese word pairs under two conditions: massed and spaced. Half the words were semantically related to each other while the other half were not. Although there were no significant differences between semantically related and unrelated items in posttest scores, semantically related items led to more interference errors than unrelated items. Furthermore, contrary to the authors’ hypothesis that spacing is particularly beneficial for semantically related items, spacing benefited unrelated items more than it did related items.

The distinction of two types of intransitive verbs—unergatives (with underlying subjects) and unaccusatives (with underlying objects)—may not exist at early stages of L2 acquisition, both being syntactically represented as unergatives. This idea, referred to here as the Unaccusative Trap Hypothesis, provides an elegant developmental account for a variety of seemingly unrelated syntactic phenomena in L2 English, Japanese, and Chinese. Target language input, structural constraints on natural language linking rules, and linguistic properties of a learner's L1s shape stages in the reorganization of the lexical and syntactic components of interlanguage grammars. Although nonnative grammars may initially override the structural constraints postulated as the Unaccusative Hypothesis (Burzio, 1986; Perlmutter, 1978) and the Uniformity of Theta Assignment Hypothesis (Baker, 1988), at later developmental stages some may still achieve conformity with the norms of natural languages.

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.

This paper has two main objectives: (a) to put the vast body of research on Swedish as a second language (SSL) into one coherent framework; and (b) to test the predictions deriving from processability theory (Pienemann, 1998a, 1998b) for Swedish against this empirical database. We will survey the 14 most prominent research projects on SSL covering wide areas of syntax and morphology in longitudinal and cross-sectional studies. This survey is the first to be carried out for Swedish, and it will bring the body of two decades of research into one unified framework. We proceed in the following steps: First, a brief summary of processability theory is given. Then the theory is used to generate a unifying framework for the development of the specific L2 grammatical system (Swedish). Finally, the new framework is tested in the above-mentioned empirical studies.

I wish to warn young men against the invincible attraction of theories which simplify and unify seductively. Ruled by the [reticularist] theory, we who were active in histology then saw networks everywhere [italics added].… This [reticularist theory] was admirably convenient, since it did away with all need for the analytical effort involved in determining in each case the course through the gray matter followed by the nervous impulse. It has rightly been said that the reticular hypothesis, by dint of pretending to explain everything easily and simply, explains absolutely nothing; and, what is more serious, it hinders and almost makes superfluous future inquiries regarding the intimate organization of the centers [italics added]. (Ramóny Cajal, 1989, pp. 303–337)

Language learners’ mindsets–their beliefs about whether language is a fixed aptitude that is immutable or a malleable capacity that can be developed–are associated with achievement goals, language-use anxiety, reappraisals of challenges, and persistence. This study integrates these mindset-related constructs to identify mindset-system profiles among foreign language learners. A latent profile analysis of 234 university students in foreign language courses revealed three distinct profiles. The fixed (21.8%) and growth (20.5%) profiles showed distinct and contrasting patterns of goals, reappraisals, anxiety, and persistence. However, most learners (57.7%) endorsed a mixed profile. Although mindsets alone did not predict grades, students in the growth profile were consistently most engaged and achieved the highest grades, suggesting that mindsets function as a system, in concert with related factors. This person-centered approach enhances our understanding of the complexity and functions of the mindset system, as well as the motivation of learners with mixed mindsets.

Recent perspectives on language transfer have highlighted the role of psychotypology and have given new life to Newmark's ignorance hypothesis. This paper examines such perspectives in the light of a body of data in French from a beginning learner of that language whose native language is English but who in addition has some knowledge of Irish, Latin, and Spanish. The fact that Spanish emerges as a privileged transfer source seems to point to a psychotypology factor, and certain distributional and contextual evidence appears to show that ignorance is in many cases triggering thè transfers. However, because ignorance does not seem to explain all cases, some speculation is entered into, on the basis of clues in the data, regarding the role of memory codes in transfer.
