汉语“N的V”结构加工的韵律制约

已有研究表明内隐韵律能够促进书面文本的理解,但以往研究多集中在重音节拍语言,而较少关注汉语这类音节节拍语言。为了探究内隐韵律作用的普遍性,研究采用眼动技术探讨了句子阅读中“N的V”结构加工的韵律制约。研究发现,“N的V”结构加工中存在稳定的韵律形式效应：动词为单音节时比动词为双音节时的注视时间更长,回视更多。韵律形式和语义关系之间存在交互作用,表现在受事语义关系条件下,在反映早期加工的凝视时间上,单音节动词条件长于双音节动词条件。但这种交互作用在晚期加工阶段则不受语义关系影响。表明“N的V”结构加工中的韵律形式效应稳定且持续。研究支持内隐韵律假说。     

演绎推理的形式和内容启动加工

聚焦推理加工初期,研究通过指导语操控主观加工倾向,考察不同指导语条件下内容可信度和形式有效性对演绎推理结果的影响,检验内容和形式两类加工过程的启动加工动态变化性。结果表明,指导语条件显著影响推理初期加工。在无提示指导语和形式判定指导语条件下,推理结果受到了形式有效性和内容可信度的影响;内容判定指导语下只受到了内容可信度的影响。证明主观加工倾向影响了内容和形式的启动加工关系,支持了动态变化性的假设。     

汉英语义通达过程的事件相关电位研究

采用事件相关电位(ERP)技术对双语表征进行了探索。实验考察了句末词呈现之后500ms内英汉两种语言的语言内和语言间语义整合在语义一致和语义不一致两种条件下的P190和N400的潜伏期和波幅。结果显示,P190具有语言的形式加工效应,这种效应在汉英两种语言加工中有明显差异;而N400具有语义加工效应,汉英两种语言的N400模式相同。结果表明双话者两种语言的形态是分别表征的,而语义是共同表征的。     

汉字识别中形旁亚词汇加工的发展研究

本研究利用语义相关判断 ,探讨儿童和成年人在汉字加工中是否存在形旁的语义激活。目标字是语义透明的合体字 (如“姐”) ;启动字选用两种与目标字语义无关的字 ,一种是共用形旁但语义不透明的合体字 (如“始”) ,一种是在频率、笔画等方面和共用形旁字匹配的无关控制字 (如“收”)。结果发现与无关控制字相比 ,儿童和成年人在共用形旁字上的“NO”反应得到了延迟 ,说明形旁可能被分解加工 ,其语义被激活。而且不同年级儿童和成年人的效应量不同 ,表明形旁的自动分解和语义激活可能存在着一个从非自动化到自动化的发展过程。与前人的诸多研究相结合 ,说明儿童和成年人对汉字的加工一样 ,是亚词汇与词汇加工并行进行的过程。     

论述理解中逻辑有效与逻辑无效条件推理的研究

句法理论和心理模型理论是解释论述理解中逻辑有效 (如MP)与逻辑无效 (如AC)条件推理机制的两种不同观点。本研究通过两项实验旨在对这两种理论加以检测。实验要求被试阅读遵循MP或AC形式的故事后对故事结论的正确性做出判断。结果表明 ,在论述理解中 ,条件前提的语义联系强度影响MP推理 ;深思熟虑对MP和AC推理均产生影响。研究结果支持心理模型理论。     

汉语动宾结构惯用语加工的基本单元：来自词切分的证据

采用词切分范式研究汉语动宾结构惯用语的理解机制, 探讨在惯用语理解中加工的基本单元, 揭示汉语动宾结构惯用语的表征方式。研究发现, 词切分范式对语义分解性不同的惯用语有不同的影响。在空格切分的形式下, 语素切分和非语素切分抑制了对语义高分解的动宾结构惯用语的通达, 却未影响对语义低分解的动宾结构惯用语的理解; 语素切分、非语素切分和空格切分均增加了对语义高分解的惯用语的错误率。在阴影切分的形式下, 非语素切分抑制了对语义高分解的动宾结构惯用语的加工, 同样未影响对语义低分解的惯用语的理解。整个研究表明, 在汉语动宾结构惯用语的表征中, 既存在着语素单元, 也存在着整语单元, 但整语是汉语动宾结构惯用语加工的优势单元。     

注意状态、认知方式与前瞻记忆的TAP效应

采用经典实验室研究范式,实验一探讨了前瞻记忆任务为知觉加工条件下,注意状态和前瞻记忆任务与进行中任务一致和不一致时对不同认知方式个体前瞻记忆成绩的影响,实验二探讨了前瞻记忆任务为语义加工条件下,注意状态和前瞻记忆任务与进行中任务一致和不一致时对不同认知方式个体前瞻记忆成绩的影响,结果表明,（1）在前瞻记忆任务加工类型是语义加工和知觉加工两种条件下,场依存与场独立个体均发现了TAP效应的存在,而且场依存个体表现出更明显的TAP效应;（2）当前瞻记忆任务与进行中任务的加工类型不一致时,场独立个体的前瞻记忆成绩明显高于场依存个体,而在两类任务加工类型一致情况下,场独立与场依存个体的前瞻记忆成绩不存在明显差异;（3）在前瞻记忆任务是知觉加工时,分心对前瞻记忆成绩有明显不利的影响;而在前瞻记忆任务是语义加工时,只有当前瞻记忆任务与进行中任务加工类型不一致时,分心对前瞻记忆才有明显不利的影响,而且在分心条件下的TAP效应更明显。

内插材料加工范式下语义加工水平(量)对内隐记忆影响的实验研究

基于内插材料加工对内隐记忆的干扰的研究范式(Martens＆Wohers．2002)所带来的启示，满足启动材料与目标词在语义线索上的匹配要求，根据启动材料的数量来控制语义加工水平(量)的大小，探索意识条件下和无意识条件下(阈限下)语义加工水平(量)对内隐记忆的影响。结果表明，无论是意识条件下．还是无意识条件下，内隐记忆成绩随语义加工水平的提高而提高。内插材料加工范式无疑是一种从更微观的角度探讨加工水平对内隐记忆的影响的较好的途径。     

修辞活动与语义演化

修辞与语义的关系向来密不可分。修辞侧重形式,语义侧重内容。内容决定形式,因此,修辞是以语义为基础和导向的,其对形式的侧重是以对内容的关注为前提条件的。符合语义内容的修辞形式效果是显著而积极的,背离语义内容的修辞形式效果是被削减而消极的。离开了语义的修辞是空洞的,难以维系。反过来,修辞作为一种以语义内容为建构基础,以表达效果为测评标准的能动性的行为活动,其发展和变化也会对语义内容产生影响,从而推动语义的演变和发展。从这个角度来看,修辞实际上是一种以语义表达为终极目标的行为活动,修辞学实际就是一门"语义运动学"。     

Covert and Overt Attention and the Processing of Cues for Location and Target Identification

An experiment was conducted to determine the role of a salient characteristic in a logical deduction task on the representational and/or processing capabilities of subjects. Subjects worked on a logical problem that was systematically altered by changing the information involved in making a particular deduction. Subjects were more likely to make the deduction under conditions of high salience, even though the logical, or processing demands of the deduction were similar in the high and low salient conditions. This finding suggests that the salience of attributes in logical deduction tasks influences the subjects' representation of them, rather than their processing of such attributes.     

Aging and individual differences in rapid two-choice decisions

The effects of aging on performance were examined in signal detection, letter discrimination, brightness discrimination, and recognition memory, with each subject tested on all four tasks. Ratcliff’s (1978) diffusion model was fit to the data for each subject for each task, and it provided a good account of accuracy and the distributions of correct and error response times. The model’s analysis of the components of processing showed that aging had three main effects: The nondecision components of processing were slower and the decision criteria were more conservative for 60- to 74-year-old and 75- to 85-year-old subjects than for college students, but the quality of the evidence on which decisions were based was as good for the older subjects as for college students on some of the tasks. Individual differences among subjects in components of processing tended to be preserved across the tasks, as was shown by strong correlations across the tasks in the parameters of the model that represent the components of processing. For example, if the evidence on which a subject’s decisions were based was good in one task, it tended to be good in all four tasks.     

任务难度对于返回抑制出现时间的影响

在返回抑制的范式下,以大学生为被斌,采用线索一靶子模式进行了两项实验.实施一发现,在觉察任务中,返回抑制在线索和靶子的时间间隔(SOA)为300ms时出现;在辨别任务中,返回抑制在SOA为700ms时出现.实验二发现在选择任务中,返回抑制在SOA为1300ms时出现.这些结果表明,随着实验任务的难度逐渐增大,返回抑制出现越来越晚.实验任务的难度是影响返回抑制出现时间的一个重要因素.     

Strategies in relational inference

Three experiments are reported in which the relationships between task format, item type, and strategy usage were investigated for a two-dimensional relational inference task. Contrary to past findings with linear syllogisms, it was found that parallel presentation (presenting problem statements simultaneously) did not result in any increased use of deduction rule processes compared with serial presentation (presenting problem statements individually). Instead, the results suggested that mental models were used by the majority of subjects, and that multiple models were more likely to be constructed with parallel presentation. It is proposed that, in general, multiple model construction will be more frequent for deduction tasks where the cognitive load is relatively low. Hence, contrary to suggestions by Polk and Newell (1995), reasoning in this way appears to be prevalent and highly robust—where supported by task format—even where the use of this strategy is disadvantageous.     

Differential involvement of left prefrontal cortex in inductive and deductive reasoning

While inductive and deductive reasoning are considered distinct logical and psychological processes, little is known about their respective neural basis. To address this issue we scanned 16 subjects with fMRI, using an event-related design, while they engaged in inductive and deductive reasoning tasks. Both types of reasoning were characterized by activation of left lateral prefrontal and bilateral dorsal frontal, parietal, and occipital cortices. Neural responses unique to each type of reasoning determined from the Reasoning Type (deduction and induction) by Task (reasoning and baseline) interaction indicated greater involvement of left inferior frontal gyrus (BA 44) in deduction than induction, while left dorsolateral (BA 8/9) prefrontal gyrus showed greater activity during induction than deduction. This pattern suggests a dissociation within prefrontal cortex for deductive and inductive reasoning.     

Developmental changes in attention-deployment skills

The ability to efficiently allocate attention between two tasks differing in payoff was investigated developmentally. Ten subjects from each of three grade levels (second, fourth, and college) performed an auditory and a visual memory task simultaneously. Modality of the primary task, difficulty of the primary task, and difficulty of the secondary task were varied factorially within subjects. The difference between primary and secondary performances increased with age: All college students, about half of the fourth graders, and none of the second graders showed a meaningful degree of differentiation between primary and secondary tasks.     

Individual differences,aging, and IQ in two-choice tasks

The effects of aging and IQ on performance were examined in three two-choice tasks: numerosity discrimination, recognition memory, and lexical decision. The experimental data, accuracy, correct and error response times, and response time distributions, were well explained by Ratcliff’s (1978) diffusion model. The components of processing identified by the model were compared across levels of IQ (ranging from 83 to 146) and age (college students, 60–74, and 75–90 year olds). Declines in performance with age were not significantly different for low compared to high IQ subjects. IQ but not age had large effects on the quality of the evidence that was obtained from a stimulus or memory, that is, the evidence upon which decisions were based. Applying the model to individual subjects, the components of processing identified by the model for individuals correlated across tasks. In addition, the model’s predictions and the data were examined for the “worst performance rule”, the finding that age and IQ have larger effects on slower responses than faster responses.     

Sex-role orientation,behavioral adaptability and personal adjustment

Bem's Sex-Role Inventory was used to classify 111 college men and women into masculine, feminine, androgynous, and undifferentiated sex-role categories. Subjects were tested for emotional expressivity (feminine task), assertiveness (masculine task), and personal integration. Sex typed and cross-sex typed subjects performed well only on those tasks which were congruent with their measured sex role. Androgynous subjects exhibited the greatest behavioral adaptability, performing well on both masculine and feminine tasks; undifferentiated subjects performed poorly on both tasks, but particularly so on sex-reversed tasks. Thus, behavioral flexibility was shown to derive from strong identifications with both masculine and feminine roles (androgyny) rather than from a simple lack of identification with either role. In addition, contrary to previous findings that masculine-typed women are better adjusted than feminine-typed women, androgynous and sex typed subjects both scored high in personal integration, with cross-sex typed subjects of both sexes scoring as low as undifferentiated subjects.     

Self-esteem and formality of instructions as variables influencing selective recall

The present study attempted to determine whether the selective recall phenomenon was related to self-esteem. The selective recall phenomenon is the inferior recall of interrupted tasks in a formal (ego-threatening) situation, relative to the recall of interrupted tasks in an informal (nonthreatening) situation. Two hundred eleven college students responded to a self-esteem inventory and then were given formal or informal instructions. They then worked on 16 tasks, and were interrupted on 8 but were allowed to complete 8. Finally, an unexpected free-recall test of task solutions was administered. Only subjects low in self-esteem exhibited the selective recall pattern. It was hypothesized that in a formal situation, interrupted activities were viewed as failures. It was assumed that the recall of failures was particularly threatening to low-self-esteem subjects, resulting in selective forgetting or selective storage of solutions. It was also found that all subjects recalled solutions from completed tasks more frequently than solutions from interrupted tasks. Several interpretations for the latter phenomenon were suggested, including a dual mechanism involving both motivation persistence and motivation reduction, and the incorporation of information into a self-referent schema.
