Imagining the End of Life: On the Psychology of Advance Medical Decision Making

Near the end of life, individuals often become too ill to express their wishes about the use of life-sustaining medical treatment. Instructional advance directives (i.e., livings wills) are widely advocated as a solution to this problem based on the assumption that healthy people can predict the types of medical treatment they will want to receive if they become seriously ill. In this paper, we review a large body of research from the psychological and medical literatures that challenges this assumption. This research demonstrates that across a wide variety of decision contexts people show limited ability to predict their affective and behavioral reactions to future situations. We outline several ways that policy and law regarding the use of advance directives could be informed by this research, and suggest a number of issues involved in advance medical decision making that could benefit from additional empirical and conceptual attention.

Are The Very Happy Too Happy?

Although positive emotions undoubtedly confer benefits, one can have too much of it. There is probably a point beyond which enjoyment interferes with realism, yet it is unclear where that point is. The original States of Mind (SOM) model (Schwartz and Garamoni, 1986; 1989) proposed that a ratio of [positive] to [positive plus negative] affective/cognitive states [P/(P+N)] of about 0.62 is optimal, but previous research indicated that higher ratios may go with good mental health. The revised balanced states of mind (BSOM) model (Schwartz, 1997) suggests a higher cutoff, with ratios above 0.90 being dysfunctional. This paper reports a study of 72 very positive subjects (mean ratio = 0.85) and assessed possible dysfunction by means of questionnaires, role-plays, and physiological responses to induced stress. Signs of dysfunction were no more frequent among the most positive subjects (ratios of 0.90 and above) than among moderately positive subjects. This suggests that there is nothing wrong with the high levels of happiness in present day society. As yet, it is still not established how much more happiness will be too much. One possibility is that standard cognition/emotion measures need to be revised in order to detect truly excessive positivity in a sensitive manner.     

情绪即社会信息模型的理论及应用

情绪即社会信息(EmotionsasSocialInformationmodel,EASI)模型旨在阐释他人情绪如何通过情感反应和推断加工机制影响观察者的决策,以及认知动机和合适性判断在其中的调节作用。文章将EASI模型与相关理论进行了辨析,并基于对63项使用该理论的实证研究的分析,梳理归纳了EASI模型在领导力、团队、顾客服务、谈判及说服领域展开的应用,以及影响EASI模型的边界条件——信息加工程度和合适性判断的具体因素。未来研究需加强系统化验证、深化与其它理论的整合、拓展应用情境和优化测量方法。     

情感触摸对心理健康的影响及应用

情感触摸指那些用来表达爱、关心、欣赏等感情或者被认为传递了这类信息的触摸行为。触摸愉悦感的产生与存在于人类多毛皮肤中名为C触觉的一组低阈值机械感受传入神经有关。早期经验和社会文化因素共同塑造了个体的触摸体验模式,积极的体验模式能够增强社会联系,促进亲密关系,触摸回避则与某些心理障碍有关。情感触摸具有治疗功能,但在心理治疗领域的应用涉及伦理问题,中介触摸和替代触摸可以作为解决触摸回避和伦理问题的新方法。     

辱虐管理的成因

辱虐管理会对组织和员工造成一系列消极影响,因此探究辱虐管理的成因对于减少和预防辱虐管理十分必要和重要。现有研究认为辱虐管理与主管的个人特征有关,或是主管自我损耗或社会学习的结果,也与受害者的特征有关。在回顾现有研究的基础上,基于情感事件理论提出了新的研究框架,并指出未来研究应关注主管对辱虐管理的态度、组织内关于辱虐管理的规范以及主管自我控制资源的恢复在辱虐管理产生过程中的作用。     

抑郁症情绪加工与认知控制的脑机制

抑郁症患者负性认知加工偏向是导致抑郁的一个主要认知因素, 是抑郁症的一个稳定特质。这种偏向与对负性情绪刺激自下而上的情绪加工增强有关, 表现为杏仁核和梭状回等脑区过度激活; 也与自上而下的认知控制功能不足有关, 表现为背外侧前额皮质、前扣带回等脑区活性不足。文章在前人研究基础上, 提出了关于抑郁症情绪加工与认知控制脑机制的一个理论假说, 即抑郁症的产生是由于抑郁症患者情绪加工脑区过度激活与认知控制脑区功能降低之间的相互作用而形成的恶性循环所介导。目前证明此理论假说在研究内容、研究材料、研究技术等方面还存在一些问题, 这些可能是未来研究的方向。     

情绪反应时间动力性的研究现状与展望

情绪反应的时间动力性系指情绪反应在时间方面的动力性质,是情感风格、情绪调节、情绪恢复等内容的重要特征,其研究对促进身心健康、完善情绪理论具有重要的理论和实践意义。文章阐述了情绪反应时间动力性的内涵与外延、相关理论,以及情绪反应时间动力性的各个参数及其影响因素的研究现状,并就未来研究增加自主生理反应指标、文化背景等因素予以展望     

汉语词汇产生中语义、语音层次之间的交互作用

采用3种方法考察汉语词汇产生中语义激活（词条选择）和音位编码这两个阶段之间的关系。实验一、二分别采用图片命名法和干扰字命名法,发现目标图片（“牛”）的语义相关词（“羊”）的语音信息得到了激活,说明汉语词汇产生中存在多重语音激活,音位编码在词条选择完成之前既已开始。实验三采用语义范畴判断法,考察语音信息的激活是否会向上反馈到词条和语义层次,发现目标图片（“羊”）的同音字（“阳”）不会促进对图片的语义判断。研究表明,多重语音激活与语音激活向词条和语义层次反馈是两个独立的,可以分割的问题。虽然实验一和二的结果符合相互作用理论,实验三的结果符合模块化观点,但就总体而言,本研究更加支持词汇产生中的模块化观点     

Les caractéristiques émotionnelles des enfants à haut potentiel

Most theoretical accounts of giftedness now include an emotional as well as an intellectual component. Yet the multi-dimensional nature of giftedness has often been overlooked in the field of education. According to practitioners, gifted children not only think differently but also feel in other ways. From this point of view, the intellectual complexity interacts with emotional intensity to provide a qualitatively different way of experiencing the world, which leads to the production of the gifted child’s greater potential for high achievement. This paper will focus on emotional features of gifted individuals, and how they could be used to complete current measures and to enrich the concept of giftedness.     

不同愉悦度面孔阈下情绪启动效应:来自ERP的证据

采用事件相关电位技术,研究阈下情绪启动效应。实验中的因素是阈下呈现的情绪启动面孔的愉悦度,分为高、低两个水平。被试的任务是对中性靶刺激面孔进行情绪判断。结果发现:被试在对靶刺激进行情绪判断时出现与启动刺激愉悦度趋于一致的启动效应;低愉悦度面孔作启动刺激条件下N1和P2的波幅显著大于高愉悦度面孔作为启动刺激的条件;不同愉悦度情绪面孔的阈下启动效应是由于启动刺激影响了对靶刺激的知觉加工所致。
