摘要：The assignment of grammatical functions has been a key feature of hierarchical (serial) models of speech production since their inception in the 1970s. This article argues that grammatical function assignment is neither sufficient nor necessary in such models. It reports a study of the effects of the conceptual accessibility of referents on the selection of English dative syntactic frames in production and shows that the effects relate to linear precedence rather than grammatical function assignment. A secondary topic addressed in the same study is whether second language speakers of English have difficulty integrating syntactic knowledge where it interfaces with conceptual accessibility in speech production. Findings suggest that advanced proficiency speakers do not and are qualitatively similar to native speakers. The implications of this for the interface hypothesis about second language acquisition are discussed. Adapted from the source document

摘要：This study examined whether late-learning English-German second language (L2) learners and late-learning German-English L2 learners use prosodic cues to disambiguate temporarily ambiguous first language and L2 sentences during speech production. Experiments 1a and 1b showed that English-German L2 learners and German-English L2 learners used a pitch rise and pitch accent to disambiguate PP-attachment sentences in German. However, the same participants, as well as monolingual English speakers, only used pitch accent to disambiguate similar English sentences. Taken together, these results indicate the L2 learners used prosody to disambiguate sentences in both of their languages and did not fully transfer cues to disambiguation from their first language to their L2. The results have implications for the acquisition of L2 prosody and the interaction between prosody and meaning in L2 production. Adapted from the source document

摘要：This article provides experimental evidence for the role of lexically specific representations in the processing of passive sentences and considerable education-related differences in comprehension of the passive construction. The experiment measured response time and decision accuracy of participants with high and low academic attainment using an online task that compared processing and comprehension of active and passive sentences containing verbs strongly associated with the passive and active constructions, as determined by collostructional analysis. As predicted by usage-based accounts, participants' performance was influenced by frequency (both groups processed actives faster than passives; the low academic attainment participants also made significantly more errors on passive sentences) and lexical specificity (i.e., processing of passives was slower with verbs strongly associated with the active). Contra to proposals made by Dbrowska and Street (2006), the results suggest that all participants have verb-specific as well as verb-general representations, but that the latter are not as entrenched in the participants with low academic attainment, resulting in less reliable performance. The results also show no evidence of a speed-accuracy trade-off, making alternative accounts of the results (e.g., those of two-stage processing models, such as Townsend & Bever, 2001) problematic.

摘要：This study examines the roles of proficiency and working memory (WM) capacity in second-/foreign-language (L2) learners' processing of agreement morphology. It investigates the processing of grammatical and ungrammatical short- and long-distance number agreement dependencies by native English speakers at two proficiencies in French, and the relationship between their proficiency and WM capacity in French and their sensitivity to agreement violations. Native English speakers at mid- and high proficiencies in French and native French speakers completed an acceptability judgment task, a self-paced reading task, and a WM task in French, and the English speakers also completed a WM task in English. The results showed that whereas all participants performed at ceiling on the acceptability judgment tasks, only the high-level L2 learners and native speakers showed some sensitivity to number agreement violations. For L2 learners, this sensitivity did not vary as a function of the length of the agreement dependency. The results also indicated that L2 learners tended to be more sensitive to agreement violations as their WM memory capacity in French increased. The implications of these results for theories of L2 morphological processing are discussed.

摘要：Although wh-words generally stay in situ in Chinese wh-questions, they can be topicalized. However, the wh-topicalization is determined at the syntax-discourse interface and has to be governed by discourse conditions; only discourse-linked (D-linked) wh-words can be topicalized, but non-D-linked ones cannot. This article reports on an empirical study that investigated English speakers' second language (L2) acquisition of Chinese wh-topicalization. The results of an acceptability judgment test indicate that advanced English speakers are sensitive to the discourse condition that governs the syntactic derivation of wh-topicalization in Chinese, as they were found to be able to make the distinction in their L2 Chinese by allowing D-linked, but not non-D-linked, wh-elements to topicalize. However, these results also indicate that wh-determiner phrases (DPs) and wh-noun phrases (NPs) differ in their sensitivity to presupposition background information in L2 Chinese wh-topicalization, and it is argued that the availability of the deictic feature in the wh-element involved is a variable affecting the D-linking properties of wh-elements in the development of L2 Chinese wh-topicalization, and this seems more likely to be a representational deficit than a processing problem.

摘要：Recently researchers have suggested that syntactic priming may facilitate the production of wh-questions with obligatory auxiliary verbs, particularly when learners are prompted to produce those questions with a wide variety of lexical items (McDonough & Kim, 2009; McDonough & Mackey, 2008). However, learners' ability to benefit from syntactic priming materials with prompt-type frequency may be mediated by their ability to recognize patterns in aural input. The purpose of this replication study is to confirm the positive impact of prompt-type frequency on learners' production of wh-questions reported by McDonough and Kim (2009), and to investigate whether its impact is mediated by learners' auditory pattern-discrimination abilities. Thai learners (n = 43) of English as a foreign language (EFL) carried out three oral tests, two sets of syntactic priming activities, and an auditory pattern-discrimination test over a 4-week period. Half of the learners carried out the syntactic priming activities with low-type-frequency prompts, whereas the other learners received high-type-frequency prompts. The results revealed a significant interaction between Type Frequency x Auditory Pattern Discrimination on the immediate and delayed posttests. The findings are discussed in terms of the potential role of individual cognitive factors in mediating the relationship between syntactic priming and second language (L2) development.

摘要：In response to new theoretical claims and inconclusive empirical findings regarding relative clauses in East Asian languages, this study examined the factors relevant to relative clause production by Korean heritage speakers. Gap position (subject vs. object), animacy (+/- animate), and the topicality of head nouns (+/- topicalization) were manipulated as experimental variables, and factors that appear to have been confounded in previous studies (e.g., context, proficiency) were controlled for or measured. Data were collected from Korean native and heritage speakers using an elicited production task. Group results failed to show a subject advantage, but individual analysis revealed that the effect of gap position varied for speakers at different levels of Korean proficiency. Results from the topicalized lead-in condition as well as error analysis revealed two different sources related to these patterns: Traditional asymmetry (i.e., subject advantage) appears to reflect the noun phrase accessibility hierarchy effect, whereas backward asymmetry (i.e., object advantage) seems to stem from word order strategy. Proficiency scores exhibited a modest correlation with the different individual response patterns. However, an animacy effect was not observed. The implications of these findings are discussed in terms of a general learning strategy, language universals based on informational prominence, the role of proficiency, and the effect of task demands.

摘要：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. Adapted from the source document

摘要：As is the case in traditional second language (L2) acquisition research, a major question in the field of L2 real-time sentence processing is the extent to which L2 learners process the input like native speakers. Where differences are observed, the underlying causes could be the influence of the learner's first language and/or differences (fundamental or not) in the use of processing strategies between learners and native speakers. Another factor that may account for L1-L2 differences, perhaps in combination with others, is individual variability in general levels of proficiency or in learners' general cognitive capacities, such as working memory and processing speed. However, systematic research into the effects of such individual differences on L2 real-time sentence processing has yet to be done because researchers in the main attempt to control for individual differences in general cognitive capacities rather than to investigate them in their own right: nevertheless, a review of the current work on L2 sentence and discourse processing raises some interesting findings. An overview of this research is presented in this paper, highlighting what appear to be the circumstances under which individual differences in factors such as working memory capacity and proficiency do or do not affect L2 sentence processing. Taken together, the data suggest that it is only under certain experimental circumstances-specifically, when participants are asked to perform a metalinguistic task directing their attention to the manipulation at the same time as comprehending the input-that individual differences in such factors as insufficient L2 proficiency and/or cognitive processing limitations, like speed and working memory influence L2 learners' real-time processing of the target input. Under these circumstances, L2 learners of for instance, a higher working memory capacity or greater proficiency are more likely to process the input like native speakers. Otherwise, learners appear to shallow process the input, irrespective of individual variability. Adapted from the source document

摘要：Structural priming (or syntactic priming) is a speaker's tendency to reuse the same structural pattern as one that was previously encountered (Bock, 1986). This study investigated (a) whether the implicit learning processes involved in long-lag structural priming lead to differential second language (L2) improvement in producing two structural types (complex, double-object dative and simple, separated phrasal-verb structures) compared to more explicit memory processes involved in no-lag structural priming and (b) whether additional explicit instruction leads to increased production of target structures than either implicit learning or explicit memory processes alone. Learners showed an overall increase in target structure production in a picture description task and marginal improvement in grammaticality judgment tests after the structural priming session. Results revealed that explicit instruction combined with structural priming speeded short-term improvement more than implicit instruction involving implicit learning alone in the form of long-lag structural priming. However, only implicit learning via long-lag structural priming resulted in increased production of the complex structure during a second testing session 1 day later. This study is the first to directly compare explicit instruction to implicit instruction in a structural priming paradigm, taking into account both the complexity of structures and the long-term effects of instruction on L2 production.

摘要：We investigate the production of subject and object who- and which-questions in the Italian of 4- to 5-year-olds and report a subject/object asymmetry observed in other studies. We argue that this asymmetry stems from interference of the object copy in the AGREE relation between AgrS and the subject in the Spec of the verb phrase. We show that different avoidance strategies are attempted by the child to get around this interference, all boiling down to a double checking of agreement: AGREE and Spec-Head. Then, we evaluate our approach from a cross-linguistic perspective and offer an account of the differences observed across early languages. Because our account seems to call both for a grammatical and a processing explanation, we end with a critical discussion of this dichotomy. Adapted from the source document

摘要：This study explores complex language in adolescents with specific language impairment (SLI) with the aim of finding out how aspects of language characteristic of typical syntactic development after childhood fare and, in particular, whether there is evidence that individuals with SLI avoid using structures whose syntactic derivation involves greater computational complexity. An analysis of spontaneous language samples of 18 French-speaking adolescents with SLI, compared to groups of typically developing speakers, showed that whereas complexity increases with age in the latter, behaviors of avoidance are clear in the former, in the form of low frequencies of complex structures, but also frequency of failed attempts and alternative strategies. Whereas increasing complexity is the hallmark of syntactic development after childhood, avoidance of complexity appears to characterize SLI after childhood. Adapted from the source document

摘要：Definitions that children provide can be a valuable measure of their syntax, and specifically, of their ability to produce relative clauses. This research explored the acquisition of subject, object, and indirect object relative clauses in 121 Hebrew-speaking children aged 3 years, 5 months to 8 years, 6 months (3;5-8;6). The children were asked to define 14 nouns, and their responses were collected and analyzed for various syntactic aspects. The main results were that children started using relative clauses in their definitions at age 3;8, and their use of relative clause increased consistently until they were 6 years old. Retesting 38 of the 6-year-olds at age 8;6 indicated no differences in several syntactic measures between their production of relative clauses at age 6 and 8;6, suggesting that the ability to produce relative clauses stabilizes around age 6. The participants made almost no grammatical errors at any of the ages, probably because they avoided the use of relative clauses when they had not mastered them yet. In the early stages participants produced mainly headless relatives, and with age the use of a relative head increased. The acquisition of relative clauses was not related to the ability to embed or to the ability to use pronouns: these abilities existed already in the youngest age group and remained constant throughout the age groups.

摘要：In this study, the influence of plausibility information on the real-time processing of locally ambiguous ("garden path") sentences in a nonnative language is investigated. Using self-paced reading, we examined how advanced Greek-speaking learners of English and native speaker controls read sentences containing temporary subject-object ambiguities, with the ambiguous noun phrase being either semantically plausible or implausible as the direct object of the immediately preceding verb. Besides providing evidence for incremental interpretation in second language processing, our results indicate that the learners were more strongly influenced by plausibility information than the native speaker controls in their on-line processing of the experimental items. For the second language learners an initially plausible direct object interpretation lead to increased reanalysis difficulty in "weak" garden-path sentences where the required reanalysis did not interrupt the current thematic processing domain. No such evidence of on-line recovery was observed, in contrast, for "strong" garden-path sentences that required more substantial revisions of the representation built thus far, suggesting that comprehension breakdown was more likely here.

摘要：Psychological research has emphasized the importance of narrative for a person's sense of self. Building a coherent narrative of past events is one objective of psychotherapy. However, in guided self-help therapy the patient has to develop this narrative autonomously. Identifying patients' narrative skills in relation to psychological distress could provide useful information about their suitability for self-help. The aim of this study was to explore whether the syntactic integration of clauses into narrative in texts written by prospective psychotherapy patients was related to mild to moderate psychological distress. Cross-clausal syntax of texts by 97 people who had contacted a primary care mental health service was analyzed. Severity of symptoms associated with mental health difficulties was assessed by a standardized scale (Clinical Outcomes in Routine Evaluation outcome measure). Cross-clausal syntactic integration was negatively correlated with the severity of symptoms. A multiple regression analysis confirmed that the use of simple sentences, finite complement clauses, and coordinated clauses was associated with symptoms (R2 = .26). The results suggest that the analysis of cross-clausal syntax can provide information on patients' narrative skills in relation to distressing events and can therefore provide additional information to support treatment decisions.
