汉语词汇产生中的义、音信息提取时间进程的ERP研究

摘 要 运用事件相关电位（ERP）技术考查了在汉语词汇产生过程中,语义提取和语音提取的时间进程。在实验过程中,给被试呈现一张图片,要求他们在小声进行图片命名之前,先基于语义信息（图上画的是物体还是动物）或语音信息（如图片名称是以字母s还是以y开头）完成一个双重选择任务。在一种情况下,反应手（左手或右手按键）由语义信息决定,是否反应（GO/NOGO）由语音信息决定;在另一种情况下,反应手由语音信息决定,是否反应由语义信息决定。结果发现,当是否反应由语义信息（动物/物体）决定时,N200的潜伏期是307ms;当是否反应由语音信息（如中文名称以S/Y开头）决定时,N200的潜伏期是447ms;两者之间存在显著的差异,即由语义信息引起的N200的潜伏期早于由语音信息引起的N200的潜伏期。结果表明,在汉语词汇产生过程中,语义提取先于语音提取。     

错误记忆的无意识机制初探

研究表明,错误记忆十分顽固,一经产生便难以消退,即使是在严格的有意识控制之下,比如预先警告条件下等。这就引起研究者对错误记忆中无意识机制的探讨。本文以错误记忆的这一顽固性特征为切人点,结合多种形式错误记忆的研究成果,尝试剖析错误记忆发生过程中无意识的作用机制,并对近年来兴起的错误记忆无意识机制的实证研究进行了介绍。

Regulating the effects of depletion through monitoring

A robust finding is that participants who perform a depleting initial self-regulatory task are less persistent on a contiguous second task than are those who perform a less arduous initial self-regulatory task. We explain this regulatory depletion effect in terms of a monitoring process. According to this view, depleted individuals focus on the resources they have devoted to a second task, neglect to monitor their performance against their standards for such activities, and prematurely suspend their performance. Consistent with this view, we demonstrate that the regulatory depletion effect can be eliminated when individuals are encouraged to monitor their performance against some standard (Studies 1, 2, and 4) or when they have a proclivity to engage in such monitoring (Studies 3 and 4).     

Patterns of maternal responding in postpartum mothers with schizophrenia

Little is known about how schizophrenia might affect how a mother responds to her infant, such as whether responding is reduced or impaired. The aim was to identify, from brief videotaped interactions, whether the responses of mothers with schizophrenia were fewer, less positive, more negative, and more ‘abnormal’ than mothers with affective disorder, and whether their infants (mean age: 15 weeks) lacked activity or initiation to which mothers could respond. Mothers with schizophrenia (N = 14) were as responsive as mothers with affective disorder (N = 31), but they showed markedly low positive responsiveness. Only the schizophrenia group exhibited non-responses as a result of being psychologically withdrawn from the interaction, and abnormal behaviors. Inconsistent to our hypothesis, infants in both groups showed similar levels of activity, initiative and negativity. The findings highlight the need for further research to examine the contribution of maternal response impairments to the developmental vulnerability of this genetically high-risk group.     

Intentional control based on familiarity in artificial grammar learning

It is commonly held that implicit learning is based largely on familiarity. It is also commonly held that familiarity is not affected by intentions. It follows that people should not be able to use familiarity to distinguish strings from two different implicitly learned grammars. In two experiments, subjects were trained on two grammars and then asked to endorse strings from only one of the grammars. Subjects also rated how familiar each string felt and reported whether or not they used familiarity to make their grammaticality judgment. We found subjects could endorse the strings of just one grammar and ignore the strings from the other. Importantly, when subjects said they were using familiarity, the rated familiarity for test strings consistent with their chosen grammar was greater than that for strings from the other grammar. Familiarity, subjectively defined, is sensitive to intentions and can play a key role in strategic control.     

现代语境中的伦理学和伦理学家

Ethics in the modern context is under the dual pressure of scientific-technological rationality and market commercialization, which has led to breakthroughs in the original boundaries of knowledge and academic methodology. The gradual separation of the domain of public life and that of private life in modern society and the former’s increasing pressure on the latter, in addition to the above dual pressure on ethics, is causing a dramatic transformation of the structure of ethical knowledge itself. All of these raise new theoretical problems for ethics and ethicists in the modern context. Answering and solving these problems makes sense for the future development of ethics as one of the classic humanities, and tests modern ethicists’ ability to realize their moral and theoretical duties.

基层党政领导干部对创造力人才特点的隐认知

该研究对48名基层领导干部的访谈和631名基层领导干部的问卷调查,通过访谈初步研究了基层领导干部的隐创造力概念,并在访谈基础上,通过因素分析等方法,编制了中国基层党政领导干部创造力人才特点量表。研究发现,中国基层领导干部对于创造力的理解更侧重于解决实际问题而非“无中生有”。在他们看来,创造力就是如何将现有的资源加以整合利用,在既定条件的约束下,用独特的方法来解决公共服务过程中面临的各种新老问题,并取得成效。中国基层领导干部的创造力人才特点包含工作灵活、激励带动：掌握新技术、敢于突破、善于学习5个维度,各维度之间有一定相关。     

Using cognitive dissonance to induce adolescents' escaping from the claw of online gaming: the roles of personal responsibility and justification of cost.

The negative impact of the Internet on adolescents has received much attention. How to reduce their pathological use of online gaming is also a critical issue. Based on cognitive dissonance theory, two experiments were conducted to examine whether personal responsibility and justification of cost may play crucial factors in impacting adolescent players' attitude change and their willingness to engage in attitude-discrepant behavior. The results of Experiment 1 revealed that adolescent players who felt a strong sense of responsibility appeared to exhibit greater attitude change. In Experiment 2, the findings indicated that players tended to employ justification of cost in order to reduce or eliminate the dissonance between their attitude toward online gaming and invested cost. Adolescent players who perceived a higher cost in online gaming were less willing to engage in attitude-discrepant behavior. Reducing adolescents ' overuse of online gaming can be appreciated through the perspective of cognitive dissonance.
