Effects of recent exposure to a conditioned stimulus on extinction of Pavlovian fear conditioning

In six experiments we studied the effects of a single re-exposure to a conditioned stimulus (CS; "retrieval trial") prior to extinction training (extinction-reconsolidation boundary) on the development of and recovery from fear extinction. A single retrieval trial prior to extinction training significantly augmented the renewal and reinstatement of extinguished responding. Augmentation of recovery was not observed if the retrieval and extinction training occurred in different contexts. These results contrast with those reported in earlier papers by Monfils and coworkers in rats and by Schiller and coworkers in humans. We suggest that these contrasting results could depend on the contrasting influences of either: (1) occasion-setting contextual associations vs. direct context-CS associations formed as a consequence of the retrieval trial or (2) discrimination vs. generalization between the circumstances of conditioning and extinction.     

大学生心理需求网络满足问卷的编制

从大学生网络使用可满足的心理需求出发,通过对网络成瘾者的深入访谈发展出与大学生网络使用有关的心理需求结构,编制了大学生心理需求网络满足问卷,分别选取418名和1183名大学生对问卷进行预试和正式施测,结果表明：（1）大学生心理需求网络满足问卷由权力、认同、迎接挑战、人际交往、逃避现实、自主、认知和成就等8种需求构成,问卷具有较好的结构效度和信度;（2）验证性因素分析结果表明大学生心理需求网络满足问卷的结构合理,模型拟合较好;（3）大学生网络使用的心理需求问卷和心理需求现实满足问卷与心理需求网络满足问卷具有相同的结构,其信度和效度达到了心理测量学的要求;（4）网络成瘾大学生和非成瘾大学生的心理需求并不存在显著差异,但网络成瘾大学生心理需求的现实满足程度显著低于非成瘾大学生,而网络满足程度显著高于非成瘾大学生,说明问卷具有较好的区分效度。这一结果同时提示在大学生网络成瘾中可能存在心理需求网络满足补偿机制。     

愚昧无知的后果往往是可怕的——对一起迷信“走火入魔”个案的分析

在信仰问题上,当前社会上有一种认识,即认为迷信鬼神是劝导人们向善的,是抑恶的行之有效的手段,不少人由此产生了迷惑,以为敬畏鬼神是一种有益的,至少是一种无害的。这种认识使得人们对封建迷信和迷信活动抱相当宽容的心态,甚至扩散到了包括共产党员在内这样本应是无神论者的     

论大学生的择业效能的培养

自我效能感是近几年来心理学研究的热点问题。大学毕业生要有良好的择业意识,如何理性提高大学生的择业效能感,成为求职心理准备和求职实务准备的首要问题。本文提出了当前大学生择业中的几种心理干预策略,为职业指导提供了新的理论视角。     

The Accuracy of Self-Reports of Condom Use and Sexual Behavior

In a study of the accuracy of self-reports of sexual behavior and condom use, 285 single, young adults in a large metropolitan area were interviewed once a week for 52 weeks, reporting on their sexual behavior each week. At 1-, 3-, 6-, and 12-month intervals, the individuals also provided self-reports of the number of times they had engaged in sex and the number of times they had used condoms since they began participating in the study. These self-reports were compared with aggregates of the weekly data, which served as a comparison standard for accuracy evaluation. The results indicate a fairly high level of accuracy in self-reports, but with 2% to 5% outliers who are highly inaccurate. The results tend to favor the assessment of sexual behavior over moderate time durations (3 or 6 months) rather than short or long durations (1 month or 12 months) when trying to maximize self-report accuracy. Accuracy was attenuated for individuals who tended to engage in sex frequently, especially at the 12-month time durations.     

目标预知对路径整合的影响

本研究采用头盔式虚拟现实与返回起点或路标的路径完成任务, 通过指导语来调控被试对于返回位置的预知, 检验目标预知对人类路径整合的影响。实验结果表明, 对于返回起点这一目标的预知可以使被试有效地忽略由于路标出现或路标数量增加而导致的干扰, 而对于返回路标这一目标的预知程度越高, 可以促使被试做出更准确的反应。这样的结果体现了目标预知作为一种非感知觉因素对于人类路径整合的影响, 也体现了人类路径整合的策略性和灵活性。     

从政治正义到社会和谐--以罗尔斯为中心的当代政治哲学反思

一引言:政治正义及其隐含的问题 在罗尔斯的政治哲学中,政治正义不仅被看做是最基本的核心理念,而且也被看做是政治哲学的全部主题.[1]罗尔斯本人对政治正义的基本解释是,通过社会或国家的基本制度安排和调节,达到全体公民之基本权利和义务的公平正义分配,从而在现代民主国家的政治框架内,实现社会普遍的公平的正义.     

边缘刺激条件下错误记忆的实验研究

随着研究的深入,研究者越来越关注错误记忆中的无意识成分。本研究试图采用边缘刺激这一方法研究错误记忆中的意识-无意识机制。结果发现,边缘刺激会引发错误记忆,但它不受刺激知觉时的意识-无意识水平限制;而且这种错误记忆-经发生便很稳定,不随测量时间间隔的延长而改变。另外。研究还发现材料这一因素往往会和其他因素交融在一起共同作用于错误记忆。     

Effects of openness, problem solving, and blaming on learning: an experiment in China

Researchers have considered interdependence and interaction among individuals and groups as critical for promoting learning in organizations. In an experiment with 80 participants in China, the present authors found that (a) open discussion compared with avoiding discussion and (b) problem solving compared with blaming stimulated the exploration, integration, and adoption of alternative ideas in addition to strengthening interpersonal relationships. The results also indicated the possibility that openness and problem solving have these effects by developing a perceived cooperative interdependence that encourages people to believe that incorporating alternative ideas can help them succeed. Avoidance and blaming, on the other hand, seemed to result in a competitive struggle to see who could impose their ideas on the other, leaving people committed to their original thinking.     

An experimental examination of social contexts and the use of power in a Chinese sample

Researchers have considered power as a largely corrupting force in organizations. In the present experiment, the authors used the theory of cooperation and competition to investigate the effects of social context on power use in a sample of Chinese participants. The present results support the reasoning that high power compared to low power provides the capacity to assist employees and that cooperative, but not competitive, goals facilitate the motivation of managers to use their power to support employees and to develop managerial conclusions that employees are capable and appreciative. These results suggest limitations to traditional organizational power theories that assume a competitive context between the powerful and those subject to power. Cooperative goals appear to be an important basis for developing the positive face of power in organizations in China and perhaps in other cultures as well.
