汉语口语句子产生中句法启动效应的眼动研究

研究利用眼动技术考察了汉语口语句子产生中的句法启动效应及其眼动模式。实验采用双宾语句(主语+谓语+间接宾语+直接宾语)、介宾语句(主语+谓语+直接宾语+间接宾语)和简单句三种启动句类型,听觉呈现启动句后呈现图片要求被试用句子进行描述,目标句类型为双宾语句或介宾语句。结果发现,启动句类型影响了目标句的句法选择及对图片中不同客体的注视时间比率及注视顺序。无论产生的目标句是否与启动句句法结构一致,双宾语句启动下对间接宾语的客体注视时间比率更高,且更多地优先注视间接宾语,介宾语句启动下对直接宾语的客体注视时间比率更高且更多地优先注视直接宾语,而在简单句启动条件下,眼动注视模式则会受到所产生目标句句法结构的影响。行为结果和眼动指标都支持了两阶段理论中结构选择和内容计划两阶段的观点。     

Function follows form: activation of shape and function features during object identification

Most theories of semantic memory characterize knowledge of a given object as comprising a set of semantic features. But how does conceptual activation of these features proceed during object identification? We present the results of a pair of experiments that demonstrate that object recognition is a dynamically unfolding process in which function follows form. We used eye movements to explore whether activating one object's concept leads to the activation of others that share perceptual (shape) or abstract (function) features. Participants viewed 4-picture displays and clicked on the picture corresponding to a heard word. In critical trials, the conceptual representation of 1 of the objects in the display was similar in shape or function (i.e., its purpose) to the heard word. Importantly, this similarity was not apparent in the visual depictions (e.g., for the target Frisbee, the shape-related object was a triangular slice of pizza, a shape that a Frisbee cannot take); preferential fixations on the related object were therefore attributable to overlap of the conceptual representations on the relevant features. We observed relatedness effects for both shape and function, but shape effects occurred earlier than function effects. We discuss the implications of these findings for current accounts of the representation of semantic memory.     

Aging and individual differences in binding during sentence understanding: Evidence from temporary and global syntactic attachment ambiguities

We report an investigation of aging and individual differences in binding information during sentence understanding. An age-continuous sample of adults (N = 91), ranging from 18 to 81 years of age, read sentences in which a relative clause could be attached high to a head noun NP1, attached low to its modifying prepositional phrase NP2 (e.g., The son of the princess who scratched himself/herself in public was humiliated), or in which the attachment site of the relative clause was ultimately indeterminate (e.g., The maid of the princess who scratched herself in public was humiliated). Word-by-word reading times and comprehension (e.g., who scratched?) were measured. A series of mixed-effects models were fit to the data, revealing: (1) that, on average, NP1-attached sentences were harder to process and comprehend than NP2-attached sentences; (2) that these average effects were independently moderated by verbal working memory capacity and reading experience, with effects that were most pronounced in the oldest participants and; (3) that readers on average did not allocate extra time to resolve global ambiguities, though older adults with higher working memory span did. Findings are discussed in relation to current models of lifespan cognitive development, working memory, language experience, and the role of prosodic segmentation strategies in reading. Collectively, these data suggest that aging brings differences in sentence understanding, and these differences may depend on independent influences of verbal working memory capacity and reading experience.     

Building syntactic structures in speaking: a bilingual exploration

In a series of three experiments we investigated syntactic priming using a sentence recall task. Participants read and memorized a target sentence for later recall. After reading a prime sentence and engaging in a distraction task, they were asked to produce the target sentence aloud. Earlier investigations have shown that this task is sensitive to a syntactic priming effect. That is, the syntactic form of the prime sentence sometimes influences the syntactic form of the recalled target. In this paper we report on a variation on this task, using Spanish-English bilingual participants. In the first two experiments we replicated the prepositional phrase priming effect using English target sentences and Spanish prime sentences. In the final experiment we investigated two additional syntactic forms, using Spanish target sentences and English prime sentences. Implications for models of syntax generation and bilingual speech production are discussed.     

Effect of presentation order on the construction of linear orders

Subjects constructed four-term linear orders from three sentences expressing the relationships between adjacent elements in the order. Successful performance was more likely when the second sentence introduced only one element not mentioned in the first sentence rather than two new elements and when the second and third sentences introduced new elements as grammatical subjects rather than objects. Except for the latter result, previously proposed theories of reasoning processes primarily in three-term series problems, predict other differences that failed to appear. Apparently, in longer series, memory limitations favor conditions in which each sentence after the first presents a relationship between a new and an old element in linguistic forms that identify the new element.     

主语优先现象及其认知机制

主语优先是言语加工中的一种语序效应, 它具体表现为三个方面：论元歧义句的理解过程中, 首论元倾向于被解释为主语; 非歧义句的理解过程中, 首论元为宾语时的加工难于首论元为主语时的加工; 关系从句的理解过程中, 主语的提取比宾语的提取更容易。本文对主语优先现象主要进行了以下方面的论述：① 结合印欧语系和非印欧语系中的各种类型的语言, 详细分析了主语优先现象及其普遍性与特殊性; ② 主语优先现象的理论解释：基于工作记忆的理论、句法关联理论、突出性特征理论和基于频率的理论; ③ 与主语优先现象有关的脑电成分及其所体现的认知加工过程。最后, 结合已有的研究, 指出了主语优先现象未来的研究方向。     

生命性在句子加工中作用的ERP研究

生命性广泛地渗透到人类语言系统中发挥其作用。本文主要结合最新和经典的有关生命性的ERP研究探讨了生命性信息起作用的模式和时间进程。在句子加工过程中,生命性影响论元的加工并影响题元结构的建构和解释。以往研究表明,生命性违反有时引发的是N400效应,有时引发的是P600效应,少数情况还表现出N400-P600的双相模式。生命性在句子加工中的作用还跟多种变量存在交互作用,语境、题元可逆性、论元之间的语义关系、动词类型和其固有的题元结构都可能影响生命性信息起作用的模式。文章最后进行总结和展望,并提出未来研究仍有必要继续探讨生命性信息加工的时间神经动态性及其在句子加工中的具体作用机制。     

Chinese‐Speaking Adults' Understanding of Argument Structure

Syntactic constructions roughly correspond to sentence meanings. Jiang and Haryu (2014) found that Chinese children can associate subject‐verb‐object (SVO) constructions with causative events at age 2, but do not always map subject‐verb (SV) constructions to noncausative events, even after reaching 5 years of age. The latter results may be attributed to the fact that Chinese allows argument‐dropping. That is, an SV sentence in Chinese sometimes includes an intransitive verb, but other times includes a transitive verb with the object dropped. This paper investigated Chinese adults' knowledge of syntax‐semantics correspondence. Experiment 1 found that Chinese adults did not always map SV sentences to noncausative events, while they almost always mapped SVO sentences to causative events. Experiment 2 found that they preferred to use SV and SVO constructions to describe noncausative and causative events, respectively. Chinese adults understand that causative and noncausative events should typically be described using transitive and intransitive constructions, respectively. However, when inferring to which event (causative or noncausative) the given sentence should be mapped, their performance seems to be regulated by actual SV sentence usage in Chinese.     

How language relates to belief,desire, and emotion understanding

Two experiments examined syntax and semantics as correlates of theory-of-mind (ToM). In Experiment 1 children’s language was examined at 3 years of age in relation to ToM at 3, 3.5, 4, and 5.5 years. Semantics predicted unique variance in later belief understanding but not desire understanding. Syntax did not explain unique variance in belief or desire. In Experiment 2 two measures of syntax and a measure of semantics were used with 65 3–5-year-olds. The syntax measures tested children’s understanding of word order and embedded clauses. They were related to false belief, but contrary to some predictions, were also related to emotion recognition. Performance on language control tasks with low syntactic demands correlated equally well with false belief. In both experiments performance on the syntax and semantics tasks was highly inter-correlated. We argue that ToM is related to general language ability rather than syntax or semantics per se.     

Induction,indifference and guessing

Pragmatism in semantics is hampered by its proponents' tendency to tie understanding too closely to our mastery of epistemic practice. Both Brandom's inferentialist semantics and the anti-realist semantics championed by Dummett and Tennant amply illustrate this tendency. As a consequence, neither theory can successfully handle cases of the innocuously unknowable in which two sentences, though mutually consistent, nonetheless cannot be known to be true together. On Brandom's account, such sentences are treated as being mutually inconsistent after all. According to both Dummett's and Tennant's version of anti-realist semantics, we cannot know that there are any true sentences of this kind. Neither result is the least acceptable, whence either theory fails. The lesson to be learnt from this failure is that understanding should not be identified with the ability to reach warranted verdicts, but with the ability to think, where thinking is constitutively involved in, but nonetheless distinct from judging.     

Object relocation: a program for setting up, running, and analyzing experiments on memory for object locations

Object Relocation is a computer program for Windows 95, with which experiments on spatial memory for object locations can be designed, run, and analyzed. Because of its clear graphical user interface, no long and complex command syntax is needed. Basically, a stimulus consists of a frame that contains a chosen number of locations (i.e., the actual spatial layout) to which objects can be assigned. When the experiment is run, these stimuli are presented to the subject for a variable period of time. Subsequently (either with or without a delay), the objects are presented in a row above the frame and have to be relocated to the correct positions. Finally, the raw data can be analyzed efficiently, using various error scores, and an SPSS-ready output file can be produced. Object Relocation is a very flexible program: New objects and positions can easily be added, and various options for presentation and relocation are present.     

Symbolically speaking: a connectionist model of sentence production

The ability to combine words into novel sentences has been used to argue that humans have symbolic language production abilities. Critiques of connectionist models of language often center on the inability of these models to generalize symbolically (Fodor & Pylyshyn, 1988; Marcus, 1998). To address these issues, a connectionist model of sentence production was developed. The model had variables (role‐concept bindings) that were inspired by spatial representations (Landau & Jackendoff, 1993). In order to take advantage of these variables, a novel dual‐pathway architecture with event semantics is proposed and shown to be better at symbolic generalization than several variants. This architecture has one pathway for mapping message content to words and a separate pathway that enforces sequencing constraints. Analysis of the model's hidden units demonstrated that the model learned different types of information in each pathway, and that the model's compositional behavior arose from the combination of these two pathways. The model's ability to balance symbolic and statistical behavior in syntax acquisition and to model aphasic double dissociations provided independent support for the dual‐pathway architecture.     

汉语句子加工中句法信息与语义信息的交互作用：来自ERP的证据

Functional constraints on sentence processing: A cross-linguistic study

English and Italian provide some interesting contrasts that are relevant to a controversial problem in psycholinguistics: the boundary between grammatical and extra-grammatical knowledge in sentence processing. Although both are SVO word order languages without case inflections to indicate basic grammatical relations, Italian permits far more variation in word order for pragmatic purposes. Hence Italians must rely more than English listeners on factors other than word order. In this experiment, Italian and English adults were asked to interpret 81 simple sentences varying word order, animacy contrasts between the two nouns, topicalization and contrastive stress. Italians relied primarily on semantic strategies while the English listeners relied on word order—including a tendency to interpret the second noun as subject in non-canonical word orders (corresponding to word order variations in informal English production). Italians also made greater use of topic and stress information. Finally, Italians were much slower and less consistent in the application of word order strategies even for reversible NVN sentences where there was no conflict between order and semantics. This suggests that Italian is ‘less’ of an SVO language than English. Semantic strategies apparently stand at the ‘core’ of Italian to the same extent that word order stands at the ‘core’ of English. It is suggested that these results pose problems for claims about a ‘universal’ separation between semantics and syntax, and for theories that postulate a ‘universal’ priority of one type of information over another. Results are discussed in the light of the competition model, a functionalist approach to grammar that accounts in a principled way for probabilistic outcomes and differential ‘weights’ among competing and converging sources of information in sentence processing.     

Long-term recognition memory for sentences

The present studies examined immediate and one-week delayed recognition performance for active and passive sentences. Recognition tests included distractor sentences wherein the logical subject, verb, of logical object of a sentence was replaced by a semantically confusable, visually confusable, or unrelated distractor. Results indicated that logical subjects, verbs, and logical objects of sentences were recognized equally well during immediate testing. During delayed testing, changes in the logical object or recipient of the action were not detected as well as verb changes of logical subject changes. The implications of these results for current sentence memory models were discussed.     

A Pinch of Salt for Frege

Michael Dummett has argued that a formal semantics for our language is inadequate unless it can be shown to illuminate to our actual practice of speaking and understanding. This paper argues that Frege’s account of the semantics of predicate expressions according to which the reference of a predicate is a concept (a function from objects to truth values) has exactly the required characteristics. The first part of the paper develops a model for understanding the distinction between objects and concepts as an ontological distinction. It argues that, ontologically, we can take a Fregean function to be generated by a property detection device that can register for any object the presence or absence of that property. This provides a direct connection between the semantics of sentences and the structure of perceptual judgment. The second part of the paper deals with arguments that have been mounted against the coherence of Frege’s semantics. It argues that some of these are question begging, while others are correct in so far as Frege’s claim is untenable if we assume that the syntactic categories singular term and predicate are primary, and the ontological categories are simply projections of these syntactic categories. However, the objections dissipate once we recognize that an independent ontological characterization of the distinction is available.     

Chinese Children’s Knowledge of Topicalization: Experimental Evidence from a Comprehension Study

There is a debate as to whether topic structures in Chinese involve A’-movement or result from base-generation of the topic in the left periphery. If Chinese topicalization was derived by movement, under the assumptions of Friedmann et al.’s Relativized Minimality (Lingua 119:67–88, 2009), we would expect children’s comprehension of object topicalization (with OSV order) to be worse than their comprehension of subject topicalization (with SVO order). This study examined 146 Mandarin-speaking children from age three to age six by means of a picture-sentence matching task with an appropriate context. The results showed a subject/object asymmetry when the topic marker is overt, and no asymmetry when the topic marker is covert. This suggests that the presence or absence of topic markers play an important role in children’s comprehension of topicalization. We propose that both structures involve movement in the adult grammar, but not in the child grammar, at least initially. Sentences without overt topic markers are base-generated on a par with gapless sentences with a topic, and the base-generation analysis is abandoned as soon as children learn the syntax and semantics of topic markers, which function as attractors of topics.     

How language does (and does not) relate to theory of mind: A longitudinal study of syntax,semantics, working memory and false belief

Forty‐four children (mean 3.8 years) were given three false belief, a working memory, and four language tasks (each designed to tap a different aspect of syntax or semantics), and were tested again 6 months later. Once the range of scores in the language and false belief tasks were equated, there was a bidirectional relation between language and theory of mind. There was no evidence for syntax playing a unique role in the contribution of language to theory of mind. No one measure of syntax or semantics was more likely than any other to predict later false belief. Nor was false belief related more to one aspect of later language (syntax vs. semantics) than another. Our data, taken with other findings, are consistent with the idea that both syntax and semantics contribute to false belief understanding. Working memory did not mediate the relation between language and theory of mind, nor did it facilitate later false belief.     

The thematic hierarchy in sentence comprehension: A study on the interaction between verb class and word order in Spanish

Linking is the theory that captures the mapping of the semantic roles of lexical arguments to the syntactic functions of the phrases that realize them. At the sentence level, linking allows us to understand “who did what to whom” in an event. In Spanish, linking has been shown to interact with word order, verb class, and case marking. The current study aims to provide the first piece of experimental evidence about the interplay between word order and verb type in Spanish. We achieve this by adopting role and reference grammar and the extended argument dependency model. Two different types of clauses were examined in a self-paced reading task: clauses with object–experiencer psychological verbs and activity verbs. These types of verbs differ in the way that their syntactic and semantic structures are linked, and thus they provide interesting evidence on how information that belongs to the syntax–semantics interface might influence the predictive and integrative processes of sentence comprehension with alternative word orders. Results indicate that in Spanish, comprehension and processing speed is enhanced when the order of the constituents in the sentence mirrors their ranking on a semantic hierarchy that encodes a verb's lexical semantics. Moreover, results show that during online comprehension, predictive mechanisms based on argument hierarchization are used rapidly to inform the processing system. Our findings corroborate already existing cross-linguistic evidence on the issue and are briefly discussed in the light of other sentence-processing models.
