句子理解过程中词类加工的功能性质

句法优先理论假设词类加工功能上优先于语义、动词论元结构和话语信息加工。来自德语和法语的证据显示, 词类违反阻断语义整合和动词论元结构加工, 因而词类优先于语义和动词论元结构。关于词类加工在功能上是否优先于话语信息加工, 尚无来自任何语言的证据。汉语证据尽管显示词类并不优先于语义, 但未充分讨论任务因素的影响。将来研究有必要使用ERP技术和违反范式, 从语义整合、动词论元结构加工和话语水平加工等多个层面, 同时操纵词类的正确性和非句法因素, 考察句法特性上与德语和法语不同的语言, 如汉语和韩语。这方面研究将有助于洞察一个语言的语言学特性如何制约或调整词类加工的功能性质。     

Facilitation by Variation: Right-to-Left Learning of English Yes/No Questions

This study advances the hypothesis that optional structural variation in language facilitates syntactic learning (facilitation‐by‐variation). Support for this is provided by a right‐to‐left‐elaboration acquisition model for English yes/no questions (YNQs). Previous studies have focused on the acquisition of ‘‘inverted’’ YNQs, a cornerstone of nativist theories of language development. Data from five American children (1;3 to 5;1) and their parents show that children hear a range of adult questions (Coming?You coming?Are you coming?), not all inverted. These variants are ordered from structurally least complex noncanonical forms to complex canonical inverted forms. I use state‐of‐the‐art econometric techniques to estimate breakpoints in YNQ time series and show that noncanonical questions emerge early in children’s speech and facilitate acquisition of canonical ones. This incremental structure‐building process relies on an adjunction strategy that augments noncanonical questions with initial auxiliaries and subjects. Development proceeds incrementally from right to left to derive auxiliary‐initial structures.     

语法启动与言语产生中的语法表征

通过对语法启动研究的总结,对言语产生过程中语法编码过程进行了研究,说明了Pickering和Branigan提出的网络模型可以很好地描述言语产生中语法加工的过程。尤其是在产生大于一个词汇的短语或句子时,存在词条层关联节点的激活。关联节点可以编码语法规则,与言语产生过程中的语法加工直接相关     

Learning Verbs Without Arguments: The Problem of Raising Verbs

This paper addresses the problem of learning the class of raising verbs (e.g. seem). These verbs are potentially problematic for learners in that unlike typical main verbs, these verbs do not stand in a semantic relation with any Noun Phrase (NP) arguments. Moreover, a second class of verbs, known as control verbs, shares certain distributional properties with raising verbs, but the two verb classes differ in important structural properties. The central problem addressed here is that of how a learner would distinguish raising verbs from control verbs, given their partial overlap in distribution. A series of experiments with English-speaking adults using a fill-in-the-blank questionnaire revealed two main types of cues that led participants to distinguish the two verb classes: inanimate NPs and semantically empty subjects (its raining) yielded the highest proportion of raising verb responses from adults, while animate NPs paired with eventive predicates yielded a high rate of control verb responses. On the basis of these results, suggestions are made as to how one should study the learning of these verbs in children.This research was supported by an NSF Postdoctoral Fellowship at the Institute for Research in Cognitive Science.

Thematic role properties of subjects and objects

This paper tests two claims about the thematic roles Agent and Patient: first, that they can be decomposed into more primitive features, as laid out in Dowty's (1991) Proto-Roles Hypothesis; and second, that these properties can be inferred directly from the grammatical roles subject and object. In Experiments 1 and 2, participants rated the Proto-Roles properties of the subject and object of transitive sentences with real verbs. Subjects were rated as more Agent-like than objects, while objects were rated as more Patient-like than subjects. Experiment 3 used transitive sentences with nonsense content words (e.g. "The rom mecked the zarg"). Even in the absence of a known verb, the results were the same. Experiment 4 examined the corollary prediction that subjects and objects should not differ on grammatically irrelevant properties (e.g. "being liquid"); this prediction was confirmed. In Experiment 5, verbs that do not permit objects (e.g. "fall," "erupt") were placed in the transitive frame. Results were the same as in Experiments 1 through 3. Moreover, the semantics of the verb were altered by the frame, indicating that participants tried to fuse the semantics of the verb with those of the frame. Possible sources of these inferences are considered.     

English-speaking children's comprehension of relative clauses: evidence for general-cognitive and language-specific constraints on development

Children must possess some ability to process input in a meaningful manner to acquire language. The present study reports on data from an experiment investigating 3- to 5-year-old English-speaking children's understanding of restrictive relative clauses manipulated for embeddedness and focus. The results of the study showed that English-speaking children acquire right-branching before center-embedded structures. Comparisons made with data from Portuguese-speaking children suggest general-cognitive and language-specific constraints on development, and with respect to English, a clause expansion approach to processing in development.     

What's different in second-language processing? Evidence from event-related brain potentials

German sentences which were either correct, contained a selectional restriction violation, or a word category violation were presented auditorily to 16 native speakers of German (L1 group) and to 16 native speakers of Russian, who had learned German after the age of 10 (L2 group). Semantic violations elicited an N400 effect for both groups, but with a reduced amplitude and a longer peak latency in the L2 group. Compared to correct sentences, sentences with a phrase structure violation elicited an early anterior negativity followed by a broad centro-parietal positivity in native speakers. By contrast, there was no differential modulation of the early anterior negativity in the L2 group. A late positivity was also elicited in the second language learners, but it was slightly delayed compared to that shown by native speakers. This pattern is discussed in terms of different degrees of automaticity with respect to the subprocesses involved in sentence comprehension.     

The “Deliberative Digital Divide:” Opinion Leadership and Integrative Complexity in the U.S. Political Blogosphere

This study examined the association between political ideology and linguistic indicators of integrative complexity and opinion leadership in U.S. political blog posts (N = 519). Using Linguistic Inquiry and Word Count (LIWC) text analysis, we found that the posts of conservative bloggers were more integratively simple than those of liberal bloggers. Furthermore, in support of a proposed opinion leadership model of integrative complexity, the relationship between ideology and integrative complexity was mediated by psychological distancing (an indicator of a hierarchical communication style). These findings demonstrate an ideological divide in the extent to which the blogosphere reflects deliberative democratic ideals.     

Representations in language processing: why comprehension is not “brute-causal”

I defend a claim, central to much work in psycholinguistics, that constructing mental representations of syntactic structures is a necessary step in language comprehension. Call such representations “mental phrase markers” (MPMs). Several theorists in psycholinguistics, AI, and philosophy have cast doubt on the usefulness of positing MPMs (Devitt, 2006; Rohde, 2002; Schank & Birnbaum, 1984). I examine their proposals and argue that they face major empirical and conceptual difficulties. My conclusions tell against the broader skepticism that persists in philosophy—e.g., in the embodied cognition literature (Hutto & Myin, 2012)—about the usefulness of positing mental representations in psychological models. Using my discussion of sentence parsing as a case study, I propose several conditions on an appropriate appeal to mental representations. Finally, I point out that the familiar arguments from productivity, systematicity, and inferential coherence suffice to establish that MPMs themselves have a constituent structure of a sort that resembles that of public-language sentences. This supports the idea that computational operations defined over MPMs are sensitive to their syntactic structure.
