语义距离半球效应的ERP研究

以通过视觉通路呈现的汉语双字词为实验材料,操纵启动词与目标词的语义距离。在词汇决定实验中记录ERP,发现：（1）除N300外,P240亦对语义距离敏感,它可能是一种与语义加工有关的新的ERP成分;（2）P240在头皮中央偏左的部位较早出现,但在头皮右侧波幅较大;（3）N300和P240都不存在语义距离的半球效应,该结果没有证实右脑更专擅远距离语义加工的假设,表明使用汉语与使用拼音文字的脑机制存在差异。     

重复学习判断中的低自信效应

学习判断是元认知判断的一种重要形式,是对未来回忆成绩的预测。重复学习判断中的低自信效应是一个有趣而反常的现象,指在重复学习测验中,学习判断往往低估了回忆成绩的增加,出现低自信的一种现象。目前,大部分实验证据支持重复学习判断中的低自信效应是普遍存在的,但也有一些实验结果表明该效应是受一定条件限制的。对于这种低自信效应的作用机制,研究者提出了不同的理论模型（如,锚定调整假说、记忆偏向消除理论、过去测验记忆的启发式假说等）进行了深入探讨。最后,文章还指出了此领域现有研究的局限和有待研究的问题     

组织支持对工作压力的中介效应研究——基于知识型员工样本的实证分析

采用中介变量分析的一般范式,以知识型员工为研究样本,实证检验了组织支持在工作压力源与压力反应之间的中介效应。研究表明:组织支持在良性压力源(如任务要求、能力要求)与积极压力反应(如组织承诺、工作满意度、工作参与感)之间发挥显著的中介作用;在负性压力源(如人际冲突、组织结构问题、时间冲突)与积极和消极压力反应(如消极工作情绪)之间都发挥显著的缓冲作用。管理者在知识型员工压力管理过程中,应高度重视组织支持的中介缓冲作用。     

从我国现行法律看安乐死的实施

安乐死作为自然人在特殊情况下对自己生命自主选择的权利,涉及人的生命权益,有关生命权立法是安乐死问题的关键.安乐死的实施与我国现行法律对生命权的严格维护产生冲突,需要我国用法律的形式肯定安乐死,并对现行法律做出适当调整,为安乐死立法留下法律空间.     

Survival of the partial reinforcement extinction effect after contextual shifts

The effects of contextual shifts on the partial reinforcement extinction effect (PREE) were studied in autoshaping with rats. Experiment 1 established that the two contexts used subsequently were easily discriminable and equally salient. In Experiment 2, independent groups of rats received acquisition training under partial reinforcement (PRF) or continuous reinforcement (CRF). Significant PREEs were observed whether extinction occurred in the same or in a different context. In Experiment 3, after PRF or CRF acquisition training, each group received extinction of the same conditioned stimulus in both the same and different contexts. PREEs were observed under both conditions, although extinction was accelerated after a contextual shift. These results were discussed in relation to the role of mediational states in the PREE.     

妊娠期肝内胆汁淤积症研究中的因果论

妊娠期肝内胆汁淤积症是一种常见的妊娠晚期并发症,对围产儿的危害极大,其确切的病因及发病机制尚未十分清楚。只有了解了疾病的起因,才能更好地进行防治。凡病必有其因,以果推因,再取因治果,这是典型的因果论的应用。     

The Reinforcing Value of Lottery Tickets,and the Synergetic Effect of Distinct Reinforcements

We present two experiments that explore the reinforcing value of lottery tickets. Participants are faced with a repeated choice task between a safe alternative and a risky prospect that provides a chance to win a lottery ticket to be played at the end of the study. Study 1 considers situations in which the risky option leads to a slightly higher expected value than the safe alternative. It shows that the risk‐taking rate increases with the probability to win the lottery ticket, but it is below 50% even when this probability is high. Study 2 shows limited sensitivity to the expected value of the risky prospect. The results can be explained with the assumption that participants rely on small samples of past experiences, and that their reaction to lottery tickets reflects large variability. The relationship between the current results and previous research on the synergetic effect of distinct reinforcements and the “pat on the back paradox” is discussed.

The Effect of Expected Value on Attraction Effect Preference Reversals

The attraction effect shows that adding a third alternative to a choice set can alter preference between the original two options. For over 30 years, this simple demonstration of context dependence has been taken as strong evidence against a class of parsimonious value‐maximising models that evaluate alternatives independently from one another. Significantly, however, in previous demonstrations of the attraction effect alternatives are approximately equally valuable, so there was little consequence to the decision maker irrespective of which alternative was selected. Here we vary the difference in expected value between alternatives and provide the first demonstration that, although extinguished with large differences, this theoretically important effect persists when choice between alternatives has a consequence. We use this result to clarify the implications of the attraction effect, arguing that although it robustly violates the assumptions of value‐maximising models, it does not eliminate the possibility that human decision making is optimal. © 2016 The Authors Journal of Behavioral Decision Making Published by John Wiley & Sons Ltd.     

Aquinas's Opposition to Killing the Innocent and its Distinctiveness within the Christian just War Tradition

This essay argues that Aquinas's position regarding the killing of innocent people differs significantly from other representatives of the Christian just war tradition. While his predecessors, notably Augustine, as well as his successors, from Cajetan and Vitoria onward, affirm the legitimacy of causing the death of innocents in a just war in cases of necessity, Aquinas holds that causing the death of innocents in a foreseeable manner, whether intentionally or indirectly, is never justified. Even an otherwise legitimate act of just war cannot legitimate causing the death of innocent people, as this can never advance the common good. This stance also contrasts sharply with much modern and contemporary double effect theorizing in relation to jus in bello. In this regard, Aquinas's position, shaped decisively by his biblical and theological commitments, may point the way towards an ethical orientation beyond the typical divisions of “pacifism” and “just war.”     

高功能孤独症者非字面语义理解缺陷：隐喻视角的ERP研究

研究采用事件相关电位技术从隐喻语义理解角度考察了高功能孤独症成人非字面语义理解中的行为特点及脑半球参与模式。行为结果显示：高功能孤独症成人对新异隐喻句的反应时最长,两类隐喻句的反应时均长于普通成人,但错误率上两组被试间无差异。脑电结果显示：高功能孤独症组对新异隐喻句的N400波幅最大,未出现半球偏侧化现象,传统隐喻句在左半球的N400波幅大于右半球,两类隐喻句的N400波幅均大于正常被试。结论：高功能孤独症成人具备隐喻理解能力,并对新异隐喻的理解做出更多努力,但右脑功能异常仍旧存在,左右半球在总体功能或神经联通性上仍旧弱于常人。
