求偶动机对男性冒险行为倾向的影响

基于风险行为的性选择理论, 通过内隐启动的方法探讨了求偶线索与奖赏线索对两性风险行为报告的影响。研究结果显示, 男性接触求偶线索, 与接触奖赏线索相比, 更有可能进行娱乐领域、健康领域与社会领域的风险行为活动; 而女性接触奖赏线索后, 与求偶线索相比, 更有可能会从事社会领域的风险行为活动; 两性接触求偶线索与奖赏线索后都较少可能从事经济领域的风险行为活动。这些结果符合性选择理论, 说明与求偶有关的信息线索能够诱导男性进行高风险活动, 因为在进化过程中冒险行为可以作为好基因的标志增加男性获得配偶的机会。这些结果还揭示了, 求偶动机对男性冒险行为的诱发作用远胜于外部动机(如金钱奖赏), 因为求偶是人类在长期进化过程中形成的本能需求。     

Manipulations of vasopressin alter aggression differently across testing conditions in monogamous and non‐monogamous Peromyscus mice

Differences in the distribution of arginine vasopressin (AVP) and a subtype of AVP receptors, the V_1a receptor, may explain dissimilarities in social behavior of monogamous and non‐monogamous rodents. Intracerebroventricular infusions of AVP and a V_1a antagonist were used in sexually naive males of two mouse species, the monogamous and highly aggressive California mouse (Peromyscus californicus) and the non‐monogamous and less aggressive white‐footed mouse (P. leucopus), to begin testing the interaction between the social system of a species and the effects of AVP on aggression. Two testing conditions, the resident‐intruder aggression test (R‐I) and the neutral arena aggression test, were used because they may differ in function and underlying biological mechanisms. In the R‐I test, administration of the antagonist lengthened attack latencies in California mice. In contrast, blocking V_1a receptors did not alter attack latencies in the R‐I test in white‐footed mice or in the neutral arena aggression test in both species. AVP also did not alter aggression in either species in either behavioral test. Overall, these results suggest that AVP may be more likely to be associated with offensive aggression as measured in the R‐I test than with neutral arena aggression and that the effects of AVP manipulations may differ between monogamous and non‐monogamous rodents.

Self‐regulation and well‐being: The influence of identity and motives

The relationship between self‐regulatory capacities and self‐esteem as well as well‐being is examined by a mediation model that views self‐regulation as promoting the development of identity achievement which, in turn, is expected to be associated with well‐being. Among secondary school students (Study 1) identity achievement mediated the association between the self‐regulatory capacity of attention control and self‐esteem. In Study 2 (university students), the mediational effect of identity achievement was found for the relationship between the self‐regulatory capacity of action control and well‐being. Explicit motives moderated this association. In sum, a firm identity enhances well‐being by lending a sense of continuity to one's life. However, explicit motives have a substitution effect by giving direction to life when lacking firm identity commitments. Copyright © 2010 John Wiley & Sons, Ltd.     

Testing multiple motives in feedback seeking: The interaction of instrumentality and self protection motives

Research indicates that information received from feedback seeking is valuable for both individual and organizational outcomes. Previous research examining the feedback seeking process has consistently suggested that individual's feedback behaviors are directly influenced by three motives. Specifically, individuals are instrumentally motivated to obtain valued information but are also motivated to protect and/or enhance their ego and to protect others' impressions of them (Ashford, Blatt and VandeWalle, 2003). The current study simultaneously examined these motives by testing the interactive effects of them on feedback seeking behavior. As predicted, they did significantly interact and the results present a deeper understanding of these motives and how employees weigh various factors in deciding whether to seek feedback within the organization.     

From Virtue to Freedom through Emotion

Spinoza conceived human freedom as a matter solely of rationality, but an understanding of the role emotion plays in moral virtue can lead one toward viewing emotionality as also essential to human freedom. A large part of human freedom consists in our tendency to give intrinsic importance to people or things outside ourselves and take them into our lives; this sense of importance, in rich and various ways, brings emotion into the center of our lives and our freedom as individuals.     

进化动机影响社会认知的一般特点及过程

进化动机影响社会认知的研究关注社会认知的起源、机能及影响。进化动机影响社会认知的一般特点有(1)特殊性, 如成功地解决求偶问题的机制不能用来解决身体危险有关的问题, (2)灵活性, 如不同类别的环境线索自动地激活与线索类别有关的社会信息。借用传统的社会认知研究方法, 研究者发现特定的线索会启动相应的进化动机(如面孔吸引力启动人们的求偶动机), 进化动机激活后就能引导人们加工有利于这种动机(或目标)实现的信息(如性别相关的风险信息等)。未来的进化动机影响社会认知的研究可以结合积极心理学(positive psychology)与具身认知(embodied cognition)的理论假设, 以产生更有价值的研究成果。     

Right Motive, Wrong Action: Direct Consequentialism and Evaluative Conflict

In this paper I look at attempts to develop forms of consequentialism which do not have a feature considered problematic in Direct Consequentialist theories (that is, those consequentialist theories that apply the criterion of rightness directly in the evaluation of any set of options). The problematic feature in question (which I refer to as ‘evaluative conflict’) is the possibility that, for example, a right motive might lead an agent to perform a wrong act. Theories aiming to avoid this phenomenon must argue that causal relationship entails motives and acts (for example) having the same moral status. I argue that attempts to ensure such ‘evaluative consistency’ are themselves deeply problematic, and that we must therefore accept evaluative conflict.     

传媒介入医患纠纷的原因及作用探析
