负性情绪材料的定向遗忘及心理机制

采用项目法定向遗忘的研究范式,在两个实验中分别采用文字和图片材料考察了情绪性记忆定向遗忘的效果及其心理机制。实验中采用了中性和负性两种实验材料,设置了两种记忆指令出现时间（2秒后提示和5秒后提示）,相对于中性材料,被试更不容易忘记负性材料。记忆指令出现的时间只影响图片材料的定向遗忘。研究表明负性情绪会干扰定向遗忘,选择性编码理论可以解释情绪性文字材料的定向遗忘,而抑制理论更能解释情绪性图片材料的定向遗忘效应。     

"Frequent frames" in German child-directed speech: a limited cue to grammatical categories

Mintz (2003) found that in English child-directed speech, frequently occurring frames formed by linking the preceding (A) and succeeding (B) word (A_x_B) could accurately predict the syntactic category of the intervening word (x). This has been successfully extended to French (Chemla, Mintz, Bernal, & Christophe, 2009). In this paper, we show that, as for Dutch (Erkelens, 2009), frequent frames in German do not enable such accurate lexical categorization. This can be explained by the characteristics of German including a less restricted word order compared to English or French and the frequent use of some forms as both determiner and pronoun in colloquial German. Finally, we explore the relationship between the accuracy of frames and their potential utility and find that even some of those frames showing high token-based accuracy are of limited value because they are in fact set phrases with little or no variability in the slot position.     

Religion and the decision to donate organs: Exploring the potential role of religious leaders

The two‐step flow model of communication (Katz, 1957 ) suggests opinion leaders obtain critical information from the mass media and, in turn, communicate this information to interpersonal contacts such as friends, family and co‐workers. It is suggested that religious leaders (RLs) may serve as opinion leaders on the topic of organ donation by debunking donation myths, promoting donation during worship services, or communicating the benefit of donation to families faced with the opportunity to participate in living or cadaveric donation. The current study examined the personal knowledge, experiences, and willingness to communicate about organ donation in a sample of RLs (N = 59) in Rochester, New York. Structured interviews were conducted in summer and fall of 2009 with a random sample of RLs. Results indicate a disparity between RLs' expressed personal support for donation and their engagement in donor registration. Approximately one‐quarter of RLs have spoken about donation during a religious service and many indicate their knowledge is not sufficient to discuss organ donation in detail. Results elaborate on how RLs may be trained to serve as opinion leaders in the promotion of organ donation. Copyright © 2010 John Wiley & Sons, Ltd.     

情绪性记忆的主动遗忘

情绪性记忆的主动遗忘, 是指人们有意识地主动地遗忘带有情绪色彩的记忆内容, 但更多的是那些带来痛苦的负性情绪性记忆。主动遗忘又分为定向遗忘和压抑遗忘, 项目法和字表法是实验室中研究定向遗忘的主要方法, 而白熊任务和TNT任务是研究压抑遗忘的主要范式, 研究者们围绕两种遗忘做了大量研究。未来的研究应更关注情绪性记忆遗忘的不同心理机制, 不同研究范式与心理机制的交互作用, 情绪性记忆遗忘的个体差异, 情绪性记忆遗忘中事件遗忘和情绪反应遗忘的分离等 问题。     

内容与自我关联性对负性情绪记忆定向遗忘的影响

本研究使用消极情绪视频片段作为实验材料,采用词表法定向遗忘范式,用2个实验分别考察了内容与自我关联性对负性情绪要义和细节记忆的定向遗忘及其权衡的影响。研究结果表明：(1)内容关联性对定向遗忘几乎没有影响,在内容关联条件下,遗忘提示只增加了要义记忆没有增加细节记忆;(2)自我关联性对定向遗忘产生了影响,自我关联条件下出现了定向遗忘,而自我无关条件下定向遗忘消失;(3) 关联性对细节和要义记忆有不同的影响,表现出明显的要义-细节权衡。     

我国人体器官捐赠移植立法问题研究

通过对我国人体器官捐赠移植立法的必要性和立法模式问题,以及我国人体器官捐赠移植法的体系和基本原则进行深入研究,指出我国人体器官捐赠移植立法宜采用统一立法模式,并遵循知情同意、人民健康第一、效用与公平、规范程序与便于操作、违法必究五项原则。     

论人体肾脏捐献中的合理补偿原则

无偿捐献作为当前获取肾脏的伦理原则,是最没有争议、最理想的,但是依靠单纯的无偿捐献所获器官远远不能满足医疗的需求。合理补偿原则既可以有效增加供体数量,又不违背伦理学原则,而且更具有道德上的广泛性和现实的可行性。相信合理补偿原则的实施将会大大促进我国器官移植事业的发展。     

我国人体器官移植的社会支持系统研究

供体来源不足严重制约了我国器官移植事业的发展。有鉴于此,建立一个非技术的人体器官移植的社会支持系统对促进我国器官移植事业的发展将具有重要意义。通过对该系统各组成部分如法律法规系统、组织管理系统、宣传教育系统、补偿系统的研究,旨在对我国器官移植事业的发展有所裨益。     

Ethical and Religious Aspects of Gamete and Embryo Donation and Legislation in Iran

During recent decades, new assisted reproductive technologies (ARTs) have improved significantly, but their ethical, social, psychological, religious and legal aspects are blurred and need further research. New techniques using donor sperm or egg allow for third party involvement in the procreation process, which has created new hope for infertile couples. The corresponding clinical applications also raise new religious questions, which require appropriate interpretation in order to make their use possible, particularly in religious communities. In this paper, we discuss the most important ethical issues and the Islamic view of third party reproduction. Likewise, the current method of third party reproduction in Iran will be described, and the advantages and disadvantages of the Act of Embryo Donation to Infertile Spouses will be stated. Consideration of this outlook could generate inspiration in many Islamic countries.     

提取抑制:来自听觉定向遗忘的证据

两个实验采用语音材料考察了词表表达方式下听觉通道的定向遗忘效应以及相应的机制。实验一中,采用2（组别）×2（词表）混合实验设计获得了听觉通道的定向遗忘效应,但是较为模糊,部分数据显示可能是额外的被试个体差异导致的;实验二中,采用2（性别）×2（词表）×2（条件）×2（科系）混合实验设计,严格控制了被试个体差异等因素,获得了较清晰的定向遗忘效应,且支持提取抑制理论。
