汉语主动句、被动句的命题表征项目顺序特点

以中国大学生为被试,采用句子—图画验证任务(sentence-picture verification task )探讨了中国学生理解汉语主动句、被动句所形成的命题表征中项目顺序特点。结果表明,无论是语义水平较高的不可逆句,还是语义水平较低的可逆句,中国学生理解汉语主动句、被动句所建构的命题表征中项目顺序均为“施事→受事”。本研究结果初步表明,中国学生理解汉语主动句和被动句时,能根据它们不同的表层结构（汉语主动句的语言表达顺序为“施事→受事”、汉语被动句的语言表达顺序为“受事→施事”）建构相同的深层结构（语义内容的命题表征项目顺序“施事→受事”）,可能是一个按照“施事→受事”固定方向进行的系列认知心理加工的过程     

学习因素对语义信息加工性质的影响

本研究通过两个行为实验,采用句子核证作业,将SAD技术和范畴学习范式有机地结合起来,对语义信息加工进程以及学习因素在其中的作用进行了考察。实验一研究了熟悉性对语义信息加工的影响。结果表明,高熟悉句的部分信息积累具有离散的趋势;低熟悉句的部分信息积累是连续性的。实验二采用范畴学习。并结合SAD技术的句子核证作业．考察了在学习过程中语义加工性质的变化。结果发现：过度学习比初始学习有更多的部分信息积累,并随信号间隔的延长而逐渐增加;过度学习表现出部分信息积累的离散性变化;初始学习则表现出连续累积的趋势。说明学习确实造成了连续性加工向离散性质的过渡。     

Summarizing information by means of causal sentences through causal graphs

The objective of this work is to propose a complete system able to extract causal sentences from a set of text documents, select the causal sentences contained, create a causal graph in base to a given concept using as source these causal sentences, and finally produce a text summary gathering all the information connected by means of this causal graph. This procedure has three main steps. The first one is focused in the extraction, filtering and selection of those causal sentences that could have relevant information for the system. The second one is focused on the composition of a suitable causal graph, removing redundant information and solving ambiguity problems. The third step is a procedure able to read the causal graph to compose a suitable answer to a proposed causal question by summarizing the information contained in it.     

晚期汉-英二语者英语被动句句法加工的ERP研究*

选取二语中等熟练者和高熟练者两类中国大学生被试,共40人(27女,13男),年龄为20~29岁,平均年龄23.88岁。采用ERP技术,以直译型英语被动句和意译型英语被动句作为实验材料,通过比较无违例、―句法违例句1‖(动词过去分词形式错误)、―句法违例句2‖(动词过去分词错误用为动词原形而造成的句法违例)以及―句法违例句3‖(动词过去分词误用为动词现在分词形式)条件下的行为数据和ERP多维数据变化的基础上,探讨了二语熟练度和语言间句法结构相似性对汉-英双语者英语被动句句法加工过程的影响。结果表明：高熟练者的反应时和正确率整体上优于中等熟练者;难易度不同的句法错误信息会直接影响被动句的加工,对明显有错误的句法信息的反应速度最快,―正确的局部句法信息‖反应时最长。对明显有错误的句法信息的正确反应率最高,最根本的句法结构的错误信息最低。最根本的句法结构的错误信息引发的P600最大,无违例条件引发的P600最小;高熟练者对最根本的句法结构的错误信息引发最大的P600效应,中等熟练者的P600效应未受不同句法错误信息的影响。行为指标支持句法加工相似性效应——直译句反应快、正确率高;意译句反应慢、正确率低。并且此效应在中等熟练者身上表现更加明显。但是脑神经活动模式未表现出句法结构相似性效应,说明二语熟练度在英语被动句加工中具有更为显著的作用。     

韵律对指代歧义的解歧作用及其机制

研究了韵律特征对指代歧义的解歧作用及其机制。所选的指代歧义句先由 33名被试确定其主要意思和次要意思。歧义句由 8名发音人朗读 ,经专家和普通听者评定后选出 1人的语料为实验材料。各有 12名在校大学生参加了重音听辨实验和名词互换语义判断实验。实验 1请被试比较歧义句中切分出来的所指名词与非所指名词的重读程度。实验 2中将不同的名词组合嵌入到主要意思与次要意思的句子框架中 ,请被试判断合成句表达的是主要意思还是次要意思。实验 3对 4名发音人的语料进行了声学分析 ,测量并比较了歧义句中的所指名词和非所指名词的音高、时长和音强。结果表明 ,韵律信息对于指代歧义有较好的解歧效果 ,消解指代歧义的基本手段是在所指名词上设置重音 ,其主要的声学表现是所指名词时长的延长。     

Future prediction with automatically extracted morphosemantic patterns

In the following paper, we investigated the usefulness of future reference sentence patterns in the prediction of the unfolding of future events. To obtain such patterns we first collected sentences that have any reference to the future from newspapers and Web news. Based on this collection, we developed a novel method for automatic extraction of frequent patterns from such sentences. The extracted patterns, consisting of multilayer semantic information and morphological information, were implemented in the formation of a general model of linguistically expressed future. To fully assess the performance of the proposed method we performed a number of evaluation experiments. In the first experiment, we evaluated the automatic extraction of future reference sentence patterns with the proposed extraction algorithm. In the second set of experiments, we estimated the effectiveness of those patterns and applied them to automatically classify sentences into future referring and other. The final model was then tested for performance in retrieving a new set of future reference sentences from a large news corpus. The obtained results confirmed that the proposed method outperformed state-of-the-art method in fully automatic retrieval of future reference sentences. Lastly, we applied the method in practice to confirm its usefulness in two tasks. The first is to support human readers in the everyday prediction of unfolding future events. In the second task, we developed a fully automatic prototype method for future prediction and tested its performance using the tasks included in the official Future Prediction Competence Test. The results indicate that the prototype system outperforms natural human foreseeing capability.     

类别型状态不确定独立否定句的加工机制：来自眼动实验的证据

探讨类别型状态不确定独立否定句(如“裙子不是蓝色的”)的动态表征过程。实验1和实验2分别仅给被试提供“与事件备择选项一致的图片” (红色裙子)和“含有否定标签的与事件否定状态一致的图片” (含有否定标签的蓝色裙子); 实验3同时提供以上两种选项。结果发现：3个实验中被试在早期均对“与事件否定状态一致的图片”注视概率更高, 在晚期阶段, 实验1仅对“与事件备择选项一致的图片” 注视概率更高, 实验2和实验3均仅对“含有否定标签的与事件否定状态一致的图片”注视概率更高, 并且选择为事件的最终状态; 实验4的评定结果表明, 当被试有充裕时间完成任务时, 37名评定者中有30名选择“与事件备择选项一致的图片”为事件的最终状态。4个实验的结果为锚激活与限制满足模型和抑制假设提供了进一步证据。     

Altering student responses through changes in teacher verbal behavior

Two experiments were conducted in a junior-high special-education class of eight pupils in an inner-city school. In the first experiment, the teacher doubled the number of words used by the pupils in answering questions by altering the type of questions asked. In the second experiment, the number of words used by students and the percentage of answers given in complete sentences, increased from less than 5% to approximately 90% when the teacher instructed the pupils to answer in complete sentences and asked another pupil to answer using a sentence if the first one did not do so. In both experiments, a brief return to baseline conditions brought a return to low levels of verbal responding. An analysis of which pupils were called on by the teacher, teacher praise, and in the second experiment the types of questions asked, indicated that these variables were not responsible for the increases in verbal responding.     

基于同义关联的句子错误记忆：发展性逆转现象及句式效应

以汉语把字句和被字句为材料,采用学习-再认方式,考察基于同义关联的句子错误记忆及其发展性逆转现象和句式效应。实验1结果发现高二和初二校正后的关键诱饵句错误再认率显著高于小学五年级,把字关键诱饵句校正后的错误再认率显著高于被字句,表明基于同义关联的句子错误记忆存在发展性逆转现象和句式效应。实验2结果发现三个年级关键诱饵句与无关句的错误再认率差异均不显著,表明去除同义关联后,句子错误记忆现象被抑制。结果表明,同义关联能诱发句子错误记忆,且句子错误记忆存在发展性逆转现象和句式效应。     

状态不确定独立否定句的加工机制

采用自定步速阅读方法与图片核证范式(picture verification paradigm)探讨状态不确定独立否定句(如“裙子不是红色的”)的动态表征过程, 包括3个实验。结果发现：(1)在否定加工的初期, 即250 ms间隔时间条件下, 读者表征事件的否定状态; 肯定句已经通达事件的实际状态。(2)在否定加工的中期, 即750 ms间隔时间条件下, 读者仍然表征事件的否定状态, 但已开始对事件的备择选项进行搜索; 肯定句仍然保持对事件实际状态的表征。(3)在否定加工的后期, 即1500 ms间隔时间条件下, 读者表征否定标记与事件的否定状态, 同时完成对备择选项的搜索; 肯定句依旧保持对事件实际状态的表征。据此, 本文提出的锚激活与限制满足模型(anchor-based activation and satisfaction constrained model)得到初步证明。     

Partial picture effects on children's memory for sentences containing implicit information

Two experiments were conducted examining the effects of partial picture adjuncts on young children's coding of information that was implied in sentences. In the two most critical conditions of these studies, subjects were presented sentences specifying a subject, an action, and a direct object with the instrument used to carry out the action not specified in the sentence (e.g., The workman dug a hole in the ground). Implicit-sentence-only subjects received only the sentences, whereas the implicit sentence + partial picture subjects also viewed a partial picture depicting the action in the sentence minus the implied instrument. The main hypothesis was that subsequent recall of the sentences given the implied instrument as a cue would be facilitated by the partial pictures provided at study, since they would lead the children to infer the instrument. That occurred with 6- to 7-year-old children, but not with preschool children. Consistent with the conclusion that the partial pictures prompted 6- to 7-year-olds to infer the instruments, implicit sentence + partial picture subjects recalled as much as subjects in two other conditions, one in which subjects were explicitly told the instruments at study and one in which subjects saw the instruments depicted in pictures at study. In contrast, preschool subjects who heard explicit sentences containing the instruments outperformed subjects who heard implicit sentences even when the implicit sentences were accompanied by pictures depicting the instruments. This failure of complete pictures to facilitate preschoolers' recall of information implied in sentences contrasts with the many demonstrations of prose learning facilitation when picture and sentence contents explicitly and completely overlap. In summary, there were developmental differences in whether (a) partial pictures significantly facilitated inferencing (and subsequent cued recall) and (b) complete pictures containing information not explicitly stated in sentences promoted cued recall of the sentences.     

Time, tense, truth

A theory of time is a theory of the nature of temporal reality, and temporal reality determines the truth-value of temporal sentences. Therefore it is reasonable to ask how a theory of time can account for the way the truth of temporal sentences is determined. This poses certain challenges for both the A theory and the B theory of time. In this paper, I outline an account of temporal sentences. The key feature of the account is that the primary bearers of truth-values are not utterances, but sentences evaluated with respect to a time. I argue that unlike other views, the present proposal can meet the challenges faced both by the A and the B theory.     

Maybe There Are No Subject-Predicate Sentences in Chinese

In this essay, I argue for the conclusion that the Chinese sentences that are regularly translated into subject-predicate sentences in English may be understood as all non-subject-predicate sentences. My argument is based on the premise that some grammatical features are crucial to yield the sense of contrast between the completeness of subject and the incompleteness of predicate. The absence of such grammatical features in Chinese makes it impossible to establish any criterion for the distinction between subject and predicate in Chinese.     

儿童句子错误记忆:发展性逆转现象及精加工推理效应

为探究文本背景下句子错误记忆的发展性逆转现象及精加工推理效应,95名有效被试学习3篇文本材料后,参与由学过句、内涵推理句、外延推理句和无关句组成的再认测验。结果发现：（1）高中二年级被试学过句的正确再认率和关键诱饵句的校正的错误再认率均显著高于小学五年级和初中二年级,后二者差异不显著;（2）内涵推理句错误再认率高于外延推理句,高中二年级被试尤甚。结论：（1）句子真实记忆随着年龄增长而增加;句子错误记忆存在发展性逆转现象,初中二年级到高中二年级是句子错误记忆发展相对迅速的阶段;（2）文本背景下,不同的精加工推理诱发了不同程度的句子错误记忆,这种精加工推理效应与一般世界知识的自上而下激活的程度有关。     

不同母语类型留学生表达汉语句子的比较

以汉语句式为测试材料,研究留学生母语是否影响他们习得汉语的问题。结果发现,留学生在主动宾句、主谓谓语句/领属句、主谓谓语句（受事主语句）和“把”字句2上的成绩表现出与其母语类型相关的规律性,母语是英语的留学生与母语是日语和韩语的留学生有显著差异。与母语语法规则接近的汉语句式较易掌握,反之就较难。这一结果提示,母语语法影响留学生习得汉语语法,在初等汉语水平阶段需要按授课对象的母语类型组织教学。     

Partial Monotonic Protothetics

This paper has four parts. In the first part, I present Leniewski's protothetics and the complete system provided for that logic by Henkin. The second part presents a generalized notion of partial functions in propositional type theory. In the third part, these partial functions are used to define partial interpretations for protothetics. Finally, I present in the fourth part a complete system for partial protothetics. Completeness is proved by Henkin's method [4] using saturated sets instead of maximally saturated sets. This technique provides a canonical representation of a partial semantic space and it is suggested that this space can be interpreted as an epistemic state of a non-omniscient agent.     

Spatial distance effects on incremental semantic interpretation of abstract sentences: Evidence from eye tracking

A large body of evidence has shown that visual context information can rapidly modulate language comprehension for concrete sentences and when it is mediated by a referential or a lexical-semantic link. What has not yet been examined is whether visual context can also modulate comprehension of abstract sentences incrementally when it is neither referenced by, nor lexically associated with, the sentence. Three eye-tracking reading experiments examined the effects of spatial distance between words (Experiment 1) and objects (Experiment 2 and 3) on participants’ reading times for sentences that convey similarity or difference between two abstract nouns (e.g., ‘Peace and war are certainly different...’). Before reading the sentence, participants inspected a visual context with two playing cards that moved either far apart or close together. In Experiment 1, the cards turned and showed the first two nouns of the sentence (e.g., ‘peace’, ‘war’). In Experiments 2 and 3, they turned but remained blank. Participants’ reading times at the adjective (Experiment 1: first-pass reading time; Experiment 2: total times) and at the second noun phrase (Experiment 3: first-pass times) were faster for sentences that expressed similarity when the preceding words/objects were close together (vs. far apart) and for sentences that expressed dissimilarity when the preceding words/objects were far apart (vs. close together). Thus, spatial distance between words or entirely unrelated objects can rapidly and incrementally modulate the semantic interpretation of abstract sentences.     

“To‐be‐forgotten” statements become less true: Memory processes involved in selection and forgetting lead to truthfulness changes of ambiguous sentences

What happens when people try to forget something? What are the consequences of instructing people to intentionally forget a sentence? Recent studies employing the item‐method directed forgetting paradigm have shown that to‐be‐forgotten (TBF) items are, in a subsequent task, emotionally devaluated relative to to‐be‐remembered (TBR) items, an aftereffect of memory selection (Vivas, Marful, Panagiotidou & Bajo, 2016). As such, distractor devaluation by attentional selection generalizes to memory selection. In this study, we use the item‐method directed forgetting paradigm to test the effects of memory selection and inhibition on truth judgments of ambiguous sentences. We expected the relative standing of an item in the task (i.e., whether it was instructed to be remembered or forgotten) to affect the truthfulness value of that item, making TBF items less valid/truthful than TBR items. As predicted, ambiguous sentences associated with a “Forget” cue were subsequently judged as less true than sentences associated with a “Remember” cue, suggesting that instructions to intentionally forget a statement can produce changes in the validity/truthfulness of that statement. To our knowledge, this is the first study to show an influence of memory processes involved in selection and forgetting on the perceived truthfulness of sentences.     

非严格弗雷格自由逻辑

莱曼(S.Lehmann)的1994年的论文从三值逻辑角度处理语言中的空词项。弗雷格认为句子的所指是真值,包含空词项的句子缺乏所指,而只有涵义,那么这样的句子不真也不假。莱曼的文章刻画了弗雷格这一思想,但有两点不尽人意之处:其一、对量词进行特殊处理,使得量词公式是二值的;其二,把包含空词项的复合句一概归于第三值。针对上述两点,本文以一度衍推系统为基础,在语义上,以偏解释函数为基础构造了一个非严格弗雷格中性自由逻辑表列系统,使得量词公式是三值的,同时使得一部分包含空词项的复合公式或真或假。
