假言推理的否定词效应

介绍假言推理中的4种否定词效应,以及相关的理论模型。被试在进行假言推理时,对前提或结论所表示的事件加进了否定词, 产生了一系列的心理效应。研究发现,范畴前提含有否定词,被试更难做出正确的推论;如果结论中含有否定词,被试却更容易做出正确的推论。为此,心理模型理论,规则理论,概率模型理论以及我国的学者对该问题都作了研究和阐述。     

库珀行政伦理理论初探

库珀是美国著名的行政伦理学专家,其行政伦理学理论从根本上说是一种责任行政理论。库珀把责任问题视为行政伦理研究的核心概念和逻辑起点,为了实现负责任的行政行为,他提出应提高行政人员伦理思考水平与伦理决策能力,促成行政责任内部控制与外部控制的有效融合,并在此基础上实现个体道德品质、组织制度、组织文化以及社会期待四要素之间的互动与持衡。库珀的行政伦理理论对中国行政伦理学理论和实践的创新具有重要启示。     

注视-西蒙效应的空间编码机制

采用注视-西蒙范式探讨了注视方向知觉的空间编码机制。实验一让被试采用双手交叉的反应方式,发现注视-西蒙效应并不随反应手的交叉而反转,说明它涉及抽象的空间方向编码,而非基于以手为参照系的半侧优势效应。实验二采用纯音音调辨别任务,发现了典型的注视-西蒙效应,结合实验一视觉通道的结果,说明注视-西蒙效应并非特异于视觉通道,它可能发生在晚期的反应选择阶段,而非早期的知觉阶段。结果支持注视线索能够自动诱发观察者形成抽象的方向表征的观点。     

内源性注意与外源性注意的跨通道比较

该研究利用空间线索技术的实验模式,考察跨视觉和听觉通道的内源性选择注意与外源性选择性注意的相互关系。实验结果表明：(1)听觉中央线索在较长的SOA(至少500毫秒)条件下,可以引导内源性空间选择性注意;同时外周线索突现也能自动化地吸引部分注意资源。(2)听觉和视觉选择注意是分离的加工通道,但二者之间存在相互联系。     

Self-Doubt Effects Depend on Beliefs about Ability: Experimental Evidence

Past research has shown negative effects of chronic self-doubt on psychological and performance outcomes. Recent correlational evidence suggests that incremental beliefs about ability ameliorate certain self-doubt effects. The current research examines whether these correlational findings are robust when subjected to experimental testing. In Experiment 1, we manipulated beliefs about ability (incremental vs. entity) and demonstrated that changing beliefs about ability altered responses to self-doubt. For individuals primed with entity beliefs, higher self-doubt was associated with greater nervousness and poorer anagram performance; for individuals primed with incremental beliefs, self-doubt had no significant effects. Experiment 2 was a 2 (manipulated belief: incremental vs. entity) × 2 (self-doubt: doubt induction vs. control) factorial design. The result showed that self-doubt induction lowered self-esteem relative to control when people were primed with entity beliefs but did not affect self-esteem when incremental beliefs were primed. However, Experiment 1 results on affect and performance were not replicated in Experiment 2. Thus, although we provide some causal evidence that inducing individuals to adopt an ability-is-malleable mindset reduces the negative effects of self-doubt, further experimental work is required to study the moderating role of mindsets for self-doubt effects.     

Manipulations of distractor frequency do not mitigate emotion-induced blindness

Emotional distractors can impair perception of subsequently presented targets, a phenomenon called emotion-induced blindness. Do emotional distractors lose their power to disrupt perception when appearing with increased frequency, perhaps due to desensitisation or enhanced recruitment of proactive control? Non-emotional tasks, such as the Stroop, have revealed that high frequency distractors or conflict lead to reduced interference, and distractor frequency appears to modulate attentional capture by emotional distractors in spatial attention tasks. But emotion-induced blindness is thought to reflect perceptual competition between targets and emotional distractors, and it is unclear whether high frequency emotional stimuli cause less disruption at this relatively early stage of processing. In four experiments, participants searched streams of images for a rotated target image. A negative or neutral distractor appeared before the target, and their relative frequency was manipulated. Across all experiments, the frequency of emotional distractors did not modulate emotion-induced blindness even when participants were explicitly informed that they would appear often or seldom. Thus, increased distractor frequency does not appear to mitigate the priority allotted to emotional distractors during perceptual competition.     

具身认知视角下的道德隐喻表征

道德隐喻已成为道德心理学研究的热点问题,随着具身认知相关理论的兴起,道德隐喻的具身研究逐渐展开。目前,具身道德隐喻的维度主要包括空间、温度、洁净、颜色、明暗、触觉、味觉、嗅觉等。具身道德隐喻的相关理论解释主要包括概念隐喻理论、具身认知理论、知觉符号理论和架构理论。今后的具身道德隐喻应更多的探讨跨文化的差异性,丰富道德隐喻具身维度的内容以及各维度之间的相关性,同时要引入道德隐喻的影响机制分析。     

羞怯对攻击的影响:安全感和社会比较倾向的中介作用

为考察安全感和社会比较倾向在羞怯与攻击之间关系的中介作用,采用大学生羞怯量表、社会比较倾向量表、安全感量表和攻击问卷对543名大学生进行测量。结果发现(1)羞怯、攻击和社会比较倾向三者之间呈显著两两正相关,且三者分别与安全感呈显著负相关;(2)羞怯对攻击的直接效应显著;(3)安全感和社会比较倾向在羞怯与攻击关系间起完全中介作用。     

文化心理学与人类学积极融合的新趋势

当前以文化心理学为代表的研究热潮被誉为是心理学发展中的第四个解释维度。这一热潮促进了多元化研究方法的发展,不仅加强了心理学实证研究的普遍性,而且提升了理论建构解释的力度和重要性。长期以来,心理学与人类学有着紧密的联系,文化心理学与人类学有着更密切的联姻。随着文化心理学与人类学的进一步积极融合,不仅为心理学的全球化发展带来了新契机,而且对于积极探索构建人类命运共同体的社会心理机制,实现心理学研究范式多样化的统一,具有重要的学理意义及现实针对性。     

Effects of the presence of others on prosocial behavior: Perceived face as mediator

Previous studies have shown that the prosocial behavior of individuals may be promoted or inhibited by the presence of others. This study hypothesizes that prosocial behavior relates to the relationships among present individuals, beyond their number. This study examines whether there is a significant difference in an individual's prosocial behavior in the presence of different types of others (strangers or friends) and whether this effect is mediated by the perception of face. Two studies that used different methods of data collection were conducted. It was found that the presence of friends promotes prosocial behavior more than does the presence of strangers. In addition, perceived face plays a mediating role between the presence of different types of people and prosocial behavior.
