Bioethics' Gender

I argue that the field of bioethics is gendered feminine, but that the methods it uses to resist this gender identity pose real harm to actual women. Starting with an explanation of what I take ‘gender’ to be, I enumerate four drawbacks to being gendered feminine. I then argue that bioethics suffers from three of the same four drawbacks. I show how the field escapes the fourth disadvantage by adopting a masculine persona that inflicts damage on women, and conclude by urging bioethicists to reflect on their complicity in abusive power systems such as gender, race and class.     

权力感的无意识启动:方法研究*

情境性启动法是对权力感进行内隐社会认知研究的重要方法。本研究首先对权力情境性启动的两种启动方法(概念启动和定势启动)进行介绍,接着通过两个实验对两种启动方法在中文背景下的适用性和有效性进行了验证,认为中文材料的概念启动和定势启动是适用和有效的,可以作为国内权力社会认知研究中启动权力的方法。最后对权力概念启动和定势启动的研究范式、方法差异和内在机制进行了讨论。     

权力基础理论:对应生存需要的权力

权力是社会关系和社会活动的核心,对应于生存需要,与人们的生活品质息息相关。采用心理–生态途径,权力基础理论将其界定为个体依据环境限制与供给满足自身需要的能力,并识别出6种基本权力类型,同时阐述了权力动态性如何通过增生性交易导致或加剧社会不平等。该理论试图从人际和群际心理层面探讨权力的起源问题,并将其与一般社会不平等现象建立联系,为权力的社会心理学研究提供了一个崭新的视角。     

权力感和群体身份对合作行为影响——社会距离的中介作用

本文基于权力的社会距离理论作为切入点,探究在合作的过程中权力感所产生的影响及社会距离所产生的中介作用、群体身份所产生的缓解作用。利用角色扮演法、情景回忆法来操控个体权力感,采用虚拟与真实的公共物品范式、囚徒困境范式来测量人际合作,通过IOS问卷测量社会距离,并用最简身份范式来控制群体身份,从而让实验得以更好探究权力感对合作有如何的影响机制。本文通过三个实验,得出的实证证据表明：（1）在虚拟的投资游戏中,高权力感的个体捐赠金额是显著少于低权力感的个体;（2）在互动情境中,个体所感知到的与其互动对象的社会距离,在权力、合作之间起到部分中介的效应;（3）对于同组内的成员,高权力感的个体相比较于低权力感的个体,有着更多的合作行为。因此,权力感增加了个体的社会距离感知、从而减少了合作行为,但互动对象中的群体身份也在有效调节着这一心理现象。     

Race for Power in Public Good Games with Unequal,Unstable Punishment Power

Decentralized punishment can maintain contributions to a public good at a high level. This positive effect holds even for situations involving inequality in punishment power, meaning that the relative costs for punishment differ between persons. We extend this line of research by examining the additional influence of instability of and thus potential competition for punishment power in public good experiments. As in previous research, inequality is operationalized by assigning the role of a ‘strong player’ to one group member, who can punish others at a reduced cost compared to other players. Instability is operationalized by the fact that the role assignment can change across rounds and is contingent on behavior in previous rounds. Three experiments show that under unequal, unstable (punishment‐) power, individuals behave more competitively and engage in a race for power resulting in detrimental effects for the group. Specifically, we find that (i) unstable power goes along with a disproportionate use of punishment; (ii) not inequality by itself but rather the combination of instability and inequality causes this effect; and (iii) this excessive use of punishment is found not only when the role of the strong player is assigned to individuals who previously behaved rather selfishly but also when prosocial behavior leads to the top, speaking for a generalizability of our findings. Implications for organizational settings are discussed. Copyright © 2016 John Wiley & Sons, Ltd.     

Sub-centimeter language organization in the human temporal lobe

The human temporal lobe is well known to be critical for language comprehension. Previous physiological research has focused mainly on non-invasive neuroimaging and electrophysiological techniques with each approach requiring averaging across many trials and subjects. The results of these studies have implicated extended anatomical regions in peri-sylvian cortex in speech perception. These non-invasive studies typically report a spatially homogenous functional pattern of activity across several centimeters of cortex. We examined the spatiotemporal dynamics of word processing using electrophysiological signals acquired from high-density electrode arrays (4 mm spacing) placed directly on the human temporal lobe. Electrocorticographic (ECoG) activity revealed a rich mosaic of language activity, which was functionally distinct at four mm separation. Cortical sites responding specifically to word and not phoneme stimuli were surrounded by sites that responded to both words and phonemes. Other sub-regions of the temporal lobe responded robustly to self-produced speech and minimally to external stimuli while surrounding sites at 4 mm distance exhibited an inverse pattern of activation. These data provide evidence for temporal lobe specificity to words as well as self-produced speech. Furthermore, the results provide evidence that cortical processing in the temporal lobe is not spatially homogenous over centimeters of cortex. Rather, language processing is supported by independent and spatially distinct functional sub-regions of cortex at a resolution of at least 4 mm.     

The money attitude of covert and overt narcissists

The money attitude of covert and overt narcissists was studied. Both covert and overt narcissism predicted the power-prestige dimension of money attitude, which were both mediated by the need for social power. Interestingly, the relationship for covert narcissism was also mediated by the fear of negative social evaluation, confirming its socially vulnerable and hypersensitive features. In addition, the anxiety and distrust factors of money attitude were correlated with covert narcissism only. Anxiety was explained by the need for power and avoidance motivation, but no significant mediator was found for distrust. These findings provide evidence to the similarities and differences between the two types of narcissism. They also shed light on narcissists’ money-related behaviors, such as investment strategy and consumer behaviors.     

Nietzsche on the health of the soul

Abstract

Health (particularly of the soul [Seele]) is a central concept in Nietzsche’s work. Yet in the most philosophically sophisticated secondary literature on Nietzsche, there has been fairly little sustained treatment of just what Nietzschean health consists in. In this paper, I aim to provide an account of some of the central marks of this health: resilience, discipline, vitality, a certain positive condition of the will to power, a certain tendency toward integration, and so on. This exposition and discussion will be the main task of the paper. Then in the concluding section of the paper, I consider a line taken in some related secondary literature, which would suggest that health might ultimately be understood in formal or dynamic terms, relating to one’s will to power and/or the unity of one’s drives. I will present the beginnings of an argument against such an account of health. In focusing on the formal and dynamic side exclusively, it cannot get the full story. In particular, it seems to me to miss the substantive dimension that is essential if we are to understand health properly. As I shall suggest, the core concept of Nietzschean health is not fully explicable except by reference to normative terms.     

Effects of Sensory Deficit on Phalanx Force Deviation During Power Grip Post Stroke

The effect of sensory deficits on power grip force from individual phalanges was examined. The authors found that stroke survivors with sensory deficits (determined by the Semmes-Weinstein monofilament test) gripped with phalanx force directed more tangential to the object surface, than those without, although both groups had similar motor deficits (Chedoke-McMaster and Fugl-Meyer), grip strength, and skin friction. Altered grip force direction elevates risk of finger slippage against the object thus grip loss/object dropping, hindering activities of daily living. Altered grip force direction was associated with altered muscle activation patterns. In summary, the motor impairment level alone may not describe hand motor control in detail. Information about sensory deficits helps elucidate patients' hand motor control with functional relevance.
