自伤行为的神经生理机制及共病障碍比较

自伤行为是危害公众心理健康的重大隐患。综合自伤行为的新近研究成果,情绪脑区、控制脑区、疼痛脑区、奖赏脑区、阿片类系统和多巴胺系统以及特定基因的异常共同参与了自伤行为。将自伤行为与自杀、成瘾、进食障碍和抑郁障碍进行比较,发现自伤行为与其共病障碍存在部分相似的发生机制。在此基础上尝试构建了自伤行为的认知神经机制假设模型,并就自伤行为神经生理机制的性别差异、发展特点及干预等提出研究展望。

二十四、吕坤论《葬书》应该烧掉——吕坤《四礼疑》按:吕坤,明代著名思想家。他说的同一墓地的后人命运不同,值得那些信风水的人深思。今译:物有适宜一县而不适宜一省,适宜一村而不适宜一乡的。紧邻的土地有好的也有坏的,紧挨着的泉水有苦的也有甜的。对吗?对。难道葬地就不是     

厌恶与恐惧面孔的记忆编码、保持、提取

情绪记忆增强效应在负性情绪记忆研究中被反复证实。尽管厌恶和恐惧同属负性情绪, 提示威胁的存在, 但由于它们的进化意义和生理功能不同, 可能导致它们对记忆的编码、保持、提取三个阶段不同的调节方向或调节强度。本文采用延迟再认任务, 采用事件相关电位考察健康成年被试对唤醒度和效价相当的恐惧和厌恶面孔的记忆编码、保持和提取。结果显示, 1)在记忆编码的早期, 被试主要加强了对恐惧面孔的注意(P1)和结构编码(N170), 而厌恶信息的加工受到了抑制; 2)从记忆编码晚期到记忆保持的整个阶段, 被试对厌恶信息的精细评估(编码阶段P3)和复述保持(保持阶段的负走向慢波)均强于恐惧信息; 3)相比于恐惧面孔, 厌恶面孔可能在工作记忆系统形成了更强的表征, 从而使被试在记忆提取时可回忆起更多的细节, 对记忆提取的信心更足(提取阶段P3)。这后两条发现是导致行为层面上厌恶情绪记忆优于恐惧情绪记忆的原因。本研究为“厌恶比恐惧具有更强的记忆增强效应”提供了高时间分辨率的脑活动层面的证据, 从而进一步揭示了负性情绪增强记忆的认知机制。     

意外地点任务中不同测试问题及意图理解与执行功能的关系

旨在讨论意外地点任务中“知否问题”与“预测问题”可能存在的差异及两者与执行功能任务的关系,并初步探讨意图理解与执行功能间的关系。用意外地点任务、膝跳反射任务和两个执行功能的任务（DCCS和手部游戏）对59名3~5岁的儿童施测。结果显示：（1）儿童在意外地点任务的“知否问题”上的表现显著好于“预测问题”,儿童对“知否问题”和“预测问题”的回答可能反映了心理理论发展的不同阶段。（2）膝跳反射任务,DCCS任务与“知否问题”三者间有显著的相关,且其高相关在排除年龄及语言能力的影响后仍保持显著。“双表征区分结构”可能是三者间具有共同的成分。     

会话、心灵与实在——塞尔言语行为思想的三个维度

Speech act is an important issue of the philosophy of language. With the development from analytic philosophy to the philosophy of language,and then to the philosophy of mind,the contemporary philosopher Searle has been dedicating himself to perfecting speech act theory for decades. Firstly,based on the whole process of conversation,he enriched speech act theory within the framework of pragmatics,widening the scope of the philosophical study of meaning; secondly,by introducing the notion of intentionality,h...     

道教与健康人格

健康人格是被誉为现代心理学第三思潮的人本主义心理学研究的中心议题之一①,与不健康人格或者"病态人格"具有某种理论上的相对应.西方心理学对健康人格的理解大多是来自对不健康人格的分析和认识,而对于像变态人格、病态人格、精神病等一些概念的认识,几乎就是西方心理学对健康人格研究的最初路线,较为典型的有我们非常熟悉的精神分析学派,就是主要通过对变态人格的研究来揭示健康人格的本质特征.     

On the generality of the displaywide contingent orienting hypothesis: Can a visual onset capture attention without top-down control settings for displaywide onset?

The contingent orienting hypothesis (Folk, Remington, & Johnston, 1992) states that attentional capture is contingent on top-down control settings induced by task demands. Past studies supporting this hypothesis have identified three kinds of top-down control settings: for target-specific features, for the strategy to search for a singleton, and for visual features in the target display as a whole. Previously, we have found stimulus-driven capture by onset that was not contingent on the first two kinds of settings (Yeh & Liao, 2008). The current study aims to test the third kind: the displaywide contingent orienting hypothesis (Gibson & Kelsey, 1998). Specifically, we ask whether an onset stimulus can still capture attention in the spatial cueing paradigm when attentional control settings for the displaywide onset of the target are excluded by making all letters in the target display emerge from placeholders. Results show that a preceding uninformative onset cue still captured attention to its location in a stimulus-driven fashion, whereas a color cue captured attention only when it was contingent on the setting for displaywide color. These results raise doubts as to the generality of the displaywide contingent orienting hypothesis and help delineate the boundary conditions on this hypothesis.     

Adjusting to death: the effects of mortality salience and self-esteem on psychological well-being, growth motivation, and maladaptive behavior

This research builds on terror management theory to examine the relationships among self-esteem, death cognition, and psychological adjustment. Self-esteem was measured (Studies 1-2, 4-8) or manipulated (Study 3), and thoughts of death were manipulated (Studies 1-3, 5-8) or measured (Study 4). Subsequently, satisfaction with life (Study 1), subjective vitality (Study 2), meaning in life (Studies 3-5), positive and negative affect (Studies 1, 4, 5), exploration (Study 6), state anxiety (Study 7), and social avoidance (Study 8) were assessed. Death-related cognition (a) decreased satisfaction with life, subjective vitality, meaning in life, and exploration; (b) increased negative affect and state anxiety; and (c) exacerbated social avoidance for individuals with low self-esteem but not for those with high self-esteem. These effects occurred only when death thoughts were outside of focal attention. Parallel effects were found in American (Studies 1-4, 6-8) and Chinese (Study 5) samples.     

Children’s Responses to Computer‐Synthesized Speech in Educational Media: Gender Consistency and Gender Similarity Effects

This study examines children’s social responses to gender cues in synthesized speech in a computer‐based instruction setting. Eighty 5th‐grade elementary school children were randomly assigned to one of the conditions in a full‐factorial 2 (participant gender) × 2 (voice gender) × 2 (content gender) experiment. Results show that children apply gender‐based social rules to synthesized speech. More specifically, children evaluate synthesized speech more positively, trust the speech more, and learn more effectively when voice gender matches either content gender (consistency attraction) and/or their own gender (similarity attraction). Children’s computer self‐efficacy was a significant covariate for their social responses to synthesized speech. Theoretical and practical implications of the current study for the design of educational media are discussed.
