心理时间旅行的方向与事件情绪效价对任务自信的影响

时间是认识和定义自我的框架之一。本研究采用两个实验,探讨心理时间旅行对任务自信的影响。实验1采用自由回忆或想象过去、未来事件的操纵,结果发现：事件情绪效价影响任务自信,时间方向以事件情绪效价为中介间接影响任务自信,想象的未来事件比回忆的过去事件更积极,进而引发更高任务自信。实验2采用平衡回忆或想象事件的情绪效价的操纵,使效价与时间方向的作用相分离,结果发现：时间方向不影响任务自信,想象事件的情绪效价对任务自信的作用受到时间方向的调节。回忆过去事件时,效价不影响任务自信;而想象未来事件时,事件效价越积极,任务自信越高。对于时间旅行中的积极事件,时间旅行的方向不影响任务自信;而对于消极事件,想象未来所引发的任务自信低于回忆过去。结论：时间旅行的方向与想象事件的情绪效价共同作用于任务自信。     

任务与字频对汉字情绪启动反转效应的影响

本研究使用ERP技术对比了效价判断与真假字判断两种任务形式下的汉字情绪启动效应。结果发现,在效价判断任务中高频目标字出现情绪启动的反转效应,效价不一致比一致条件下反应时短,诱发了较大的P200;低频目标字出现情绪启动的一致性效应,效价一致比不一致条件下反应时短,诱发了较大的P200与N400。真假字判断任务中高频和低频目标字均出现情绪启动的一致性效应。情绪启动的反转效应依赖于刺激材料的可通达性与注意导向,启动字与目标字的反应竞争关系导致了情绪启动的反转效应。     

Dissociation and memory suppression: A comparison of high and low dissociative individuals’ performance on the Think–No Think task

The present study examined whether high and low dissociative individuals differ in their ability to keep target stimuli out of their awareness (suppression) and how this relates to their memory of those targets during a later cued recall task. The prediction was that high dissociators display a general inability to focus attention and that their distractibility undermines successful suppression, thereby enhancing memory for suppressed items. College students with high (n = 35) and low (n = 33) scores on the Dissociative Experiences Scale participated in a Dutch version of Anderson and Green’s (2001) Think–No Think (TNT) task. Overall, a significant suppression effect emerged. However, no differences between high and low dissociators were observed. Thus, the present results do not confirm that dissociation is linked to heightened distractibility.     

Improving judgmental forecasts with judgmental bootstrapping and task feedback support

This study examines the utility of two widely advocated methods for supporting judgmental forecasts—providing task feedback and providing judgmental bootstrapping support. In a simulated laboratory based experiment that focused on producing composite sales forecasts from three individual components, we compared the effectiveness of these two methods in improving final judgmental forecasts. In the presence of cognitive feedback task, feedback led to better forecasts than providing judgmental bootstrap forecasts. Simply providing bootstrap forecasts was of no additional benefit over a control condition. This was true in terms of the Brunswik Lens model measures of achievement, knowledge, and consistency, and in terms of forecast accuracy. This occurred both in stable environments and when special events (unusual one‐time events requiring adjustments to the forecasts) arose. Copyright © 2005 John Wiley & Sons, Ltd.

中国文化中自尊结构的内隐社会认知研究

本研究同时运用外显的自陈式量表和自行设计的内隐联想测验(IAT)及Go/No-go联想任务(GNAT)来研究中国大学生的自尊结构,结果表明：(1)运用内隐联想测验和Go／No-go联想任务来测量内隐自尊是敏感的;(2)中国文化中自尊是一个双重的结构：包括一个内隐的成分和一个外显的成分。(3)自尊在内隐和外显两个层面上都不存在性别差异。     

有关条件推理中概率效应的实验研究

通过预备实验选取了四种不同条件概率的条件规则和四种不同前后件概率组合的条件规则作为实验材料,以大学生为被试,考察了两种概率因素(条件概率和前后件概率)对条件推理的演绎形式(MP、DA、AC、MT)以及变通形式(四卡问题)的影响。结果表明,两种概率因素对四种条件推理的影响都非常显著,研究进一步证实了人们对四种推理的认可程度主要与范畴前提的概率成正比的结论;但概率因素对四卡问题的解决影响不明显。     

De‐escalation after repeated negative feedback: emergent expectations of failure

Research on willingness to make marginal investments (e.g., the escalation and sunk cost literatures) has often focused on project completion decisions, such as the “radar‐blank plane.” This paper discusses a fundamentally different type of marginal investment decision, that of couples deciding whether to continue infertility treatment in the face of repeated failures. Two experiments based on this context show that when people face multiple independent chances to achieve a valued goal but are unsure about chances of success, premature quitting or “de‐escalation” is the norm. Repeated negative feedback appears to induce individuals to see each successive failure as more and more diagnostic. As a result, even a short series of failed attempts evokes beliefs that future attempts will also fail. These emergent expectations of failure, generated by causal attribution processes, associative learning, and/or discounting of ambiguous information, appear very compelling and induce people to forgo profitable marginal investments.

Shedding Dialectical Tiers: A Social-Epistemic View

Is there a duty to respond to objections in order to present a good argument? Ralph Johnson argues that there is such a duty, which he refers to as the “dialectical tier“ of an argument. I deny the (alleged) duty primarily on grounds that it would exert too great a demand on arguers, harming argumentation practices. The valuable aim of responding to objections, which Johnson 's dialectical tier is meant to satisfy, can be achieved in better ways, as argumentation is a social-epistemic activity.     

同时线索化条件下儿童返回抑制的容量

返回抑制是对先前注意过的目标再次做出反应的时候反应时延长的一种现象。返回抑制具有一定的生物学意义,忽略已经注意过的位置(或客体),使得有机体可以更加有效的注意新的内容。基于这一点,返回抑制现象应该可以在多个已经注意过的位置出现,这便是返回抑制的容量问题。在本研究中,采用同时呈现的线索化方式,考查8岁、10岁儿童在不同的实验任务——觉察任务和辨别任务——中的返回抑制容量。结果发现觉察任务中,10岁组儿童和8岁组儿童最多在5个线索化位置上出现返回抑制,但8岁年龄组的返回抑制容量缺乏稳定;辨别任务中,10岁年龄组只在一个位置上出现返回抑制,而8岁年龄组并没有明显返回抑制现象出现。年龄因素和任务类型对儿童返回抑制容量都产生了一定程度的影响。
