论现代临床医学发展的人文走向

我们不能用静止的眼光看待当代的医学。在整个“以人为本”的环境背景和其它因素的影响下,近二十多年以来,现代医学正在开始走出人性冷漠的阴影,出现了一些重要的人文走向,尽管这还只是开始,但无疑给人们以希望和信心。     

Contextual effects on prejudiced attitudes: When the presence of others leads to more egalitarian responses

In the present paper, we tested the hypothesis that the physical presence of other ingroup members may ameliorate Whites’ spontaneous affective responses toward Blacks. Results of Study 1 demonstrated that IAT-assessed attitudes toward Blacks were indeed less negative when participants were tested in small groups rather than individually. Study 2 shed light on the underlying processes by demonstrating that respondents at the presence of others displayed increased accessibility to egalitarian-related concepts after Black primes, as compared to respondents tested individually. Overall, results point to the wide malleability of spontaneous affective responses and to the possibility that contextual factors, like the presence of other individuals, might automatically activate egalitarians goals. Results are discussed in relation to current models of automatic intergroup bias and preconscious control over it.     

Seeing is not enough: manipulating choice options causes focusing and preference change in multiattribute risky decision‐making

We show that preferences depend on the attributes that can be directly manipulated when people need to integrate multiple sources of information because direct manipulation causes focusing bias. This effect appears even when all relevant information is simultaneously and explicitly presented at the time the decisions are made. Participants decided how much to save, what investment risk to take and observed the future financial consequences in terms of the mean and variability of the expected retirement income. Participants who manipulated only the future income distribution saved more and took less risk. This effect disappears when the risk‐related variables are removed, which indicates that task complexity is a mediator of such focusing effects. A more balanced trade‐off between the choice attributes was selected when all attributes were manipulated. However, when there is a dichotomy between manipulating versus observing choice attributes, then decisions were based mostly on the manipulated attributes.

面部表情的跨文化表达与识别研究述评

近年来面部表情的跨文化研究显示出更多的跨文化一致性和差异性证据。自发面部表情的表达和识别、组内优势效应以及面部表情信息的上下不对称性已成为该领域的研究热点。方言理论、中国民间模型和EMPATH模型从三种不同的角度对面部表情跨文化研究的结果进行了理论解释。而表达规则和解码规则以及语言效应是面部表情跨文化表达与识别的重要影响因素。今后, 面部表情跨文化的表达和识别研究应更加关注面部表情特征信息和影响因素这两个方面。     

Spontaneous rotation of nanoparticles in a medium

In many experiments, the effects of spontaneous rotation of nanoparticles in a medium have been observed. In the article it has been shown that the reason for the spontaneous rotation of nanoparticles in a medium may be due to an increase in rotational entropy that accompanies the increasing rotational frequencies of the nanoparticles. An equation describing the rotational motion of the nanoparticles in a medium is obtained and its solution is found. It is shown that the formation of a large number of randomly oriented nanocrystals may be a reason for the forming of an amorphous phase upon cooling a melt.     

Causal and moral responsibility: Antecedents and consequences of group‐based guilt

In six studies (N = 1045) conducted in three European countries, we demonstrate distinctions between causal responsibility, group‐based guilt, and moral responsibility. We propose that causal responsibility is an antecedent of group‐based guilt linking the ingroup to previous transgressions against the victim group. In contrast, moral responsibility is a consequence of group‐based guilt and is conceptualized as a sociomoral norm to respond to the consequences of the ingroup's transgressions and the current needs of the victim group. As such, moral responsibility can be stimulated by group‐based guilt and directly predicts individual action intentions. Studies 1 and 2 focus on the conceptual distinctions among the three constructs. Study 3 tests the indirect effect of causal responsibility on moral responsibility via group‐based guilt. The remaining studies explore the mediating role of moral responsibility in associations between group‐based guilt and compensatory action tendencies, that is, financial compensation (study 4), approach and avoidance tendencies (study 5) and public apology (study 6). Together these studies show that causal and moral responsibility are psychologically distinct concepts from group‐based guilt and that moral responsibility plays an important role in shaping the effects of group‐based guilt on behavioral intentions.

Isolation effects and the neglect of indirect effects of fiscal policies

People tend to focus on salient cues, ignoring others. We demonstrate such isolation effects in situations involving taxes and public finance, through experiments conducted on the World Wide Web. In general, subjects minimized or ignored the longer‐term or indirect effects of tax policies, such as price increases from business taxes. Subjects preferred “hidden” taxes to transparent ones, failing to think through who would ultimately pay. The preference for hidden taxes was greater when it was uncertain who would pay. When subjects were prompted to think about indirect effects, their preference for hidden taxes was reduced but not eliminated. These observations are symptoms of general tendencies not to think ahead about the effects of public policies. Copyright © 2006 John Wiley & Sons, Ltd.     

Spontaneous Trait Associations and the Case of the Superstitious Banana

We explored whether spontaneous trait transference (STT) occurs in cases where inanimate objects, rather than human bystanders, are presented in the context of trait-implicative behavior. The results provide a vivid demonstration of the associability of primed trait constructs by demonstrating STT to inanimate objects to which one does not normally attribute traits (e.g., superstitious being associated with a banana). This finding is consistent with the notion that the trait associations involved in STT are formed independent of person perception processes. The implications of this finding for the types of associative processes exposed by the popular savings in relearning methodology are discussed.     

观点采择是否一定促进内隐宽恕?——受害者对伤害动机认同的调节作用

以往研究多认为观点采择可有效促进宽恕,近期研究则开始关注观点采择诱发宽恕等亲社会行为的边界条件。结合“换位体验”和内隐态度测量范式,本研究考察了受害者对伤害动机的认同在被动和自发观点采择影响内隐宽恕过程中的调节作用。实验1发现当人际伤害中存在人们无法认同的恶意不道德动机时,被动和自发观点采择都抑制了受害者对施害者的内隐宽恕且后者的抑制效应更显著。实验2则进一步操纵了不同类型受害者对施害者伤害动机的认同差异,低认同组与实验1结果相同,即被动和自发观点采择中都抑制了内隐宽恕且后者的抑制效应更显著,但高认同组在两种观点采择中都促进了内隐宽恕且二者的促进效应无显著差异。本研究揭示了伤害动机认同在不同类型观点采择影响内隐宽恕过程中起到的调节作用,进一步丰富了对观点采择和宽恕间复杂关系的认识。
