Trust is essential to personal well-being and economic success, but it cannot occur without accepting the possibility of betrayal. In the experimental trust game, game-theoretic rationality prescribes that trust decisions should depend on the potential risk (egocentric costs and benefits) and the probability of reciprocity (derived from the trustee's temptation to defect). The current work tests the relative weights of these elements. Experiment 1 shows that trust increases when costs decrease and benefits increase. The latter finding is critical because increasing the trustor's benefit also means increasing the trustee's temptation to defect. Hence, this finding suggests that egocentrism prevails over perspective-taking. Experiment 2 shows that the trustee's temptation to defect (negatively) affects trust, but only when the trustor's cost and benefit are favorable. Results are interpreted as reflecting a boundedly rational decision process.  相似文献

It has been shown that optimists tend to rely more on their prior expectations than sensory input when making decisions of an intense nature (Geers & Lassiter, 2002). We investigated the degree to which this tendency persists over a range of discrepancies between prior cues and actual stimuli. Eighty‐seven participants were shown a subset of happy, sad and fearful pictures drawn from the Ekman facial expressions of emotion (Ekman & Oster, 1979). Each picture was preceded by a verbal cue indicating the impending emotional expression and intensity. The displayed pictures were either in agreement, slightly discrepant or very discrepant with the cue. Participants rated the extent to which they agreed/disagreed with the expectation cue. Probit signal detection models were used to produce acquiescence for each subject at each level of discrepancy. Correlation analysis was performed on acquiescence and dispositional optimism scores. There was a significant correlation between all acquiescence scores for levels of discrepancies and dispositional optimism. Optimism appears to be a trait associated with acquiescence. The apparent tendency of optimists to comply may be due to a cognitive style that relies on expectations, such that it takes them longer to recognise the extent of discrepancy between expectations and incoming information.

Having a sense of purpose has been discussed as a developmental asset for youth and as an outgrowth of establishing a sense of identity. Using the identity capital model as a theoretical framework, 3 studies examined purpose as a mediator in the relationship between identity and well-being among adolescents and emerging adults. In Study 1A, (n = 110), purpose commitment was positively associated with positive affect, hope, happiness among adolescents, and fully mediated associations between identity commitment and these indices of well-being. These findings were replicated in Study 1B (n = 398), with a sample of emerging adults and using different measures of well-being. In Study 2, multilevel random coefficient modeling analyses examined the role of identity and purpose in the daily lives of adolescents (n = 135). Results showed that purpose commitment fully mediated the relationship between identity and changes in daily positive and negative affect. Overall, findings suggest that cultivating a sense of purpose in life may be an important mechanism through which a stable identity contributes to well-being.  相似文献

Preferences for partners with symmetric and sex-typical faces are well documented and considered evidence for the good-genes theory of mate choice. However, it is unclear whether preferences for these traits drive the real-world selection of mates. In two samples of young heterosexual couples from the United Kingdom (Study 1) and the United States (Study 2), the authors found assortment for facial symmetry but not for sex typicality or independently rated attractiveness. Within-couple similarity in these traits did not predict relationship duration or quality, although female attractiveness and relationship duration were negatively correlated among couples in which the woman was the more attractive partner. The authors conclude that humans may mate assortatively on facial symmetry, but this remains just one of the many physical and nonphysical traits to which people likely attend when forming romantic partnerships. This is also the first evidence that preferences for symmetry transfer from the laboratory to a real-world setting.  相似文献

The human face is important for social communication and in attractiveness judgements. Previous studies indicate that several facial traits may be related to mental and physical health and there is some evidence that individuals are able to judge past health on the basis of facial appearance. The current study builds on this prior work, examining the relationship between static facial appearance and self-reported stress and health. Specifically, we examined (1) within and between individual stress (Study 1) by photographing the same participants at two times, once in a relatively stress free and once in a stressful time, and (2) between individual health (Studies 2A and 2B) by examining self-reported past number of colds as a measure of immune function. All studies demonstrated that individuals could judge the stress and physical health of others from static facial appearance alone at rates greater than chance. Such accuracy may reflect selection pressures to identify stress free and healthy social partners.  相似文献

This paper examines the religious tradition of ‘negative theology’, and argues that it is doubtful whether it leaves room for belief in God at all. Three theologians belonging in different degrees to this tradition are discussed, namely John Scotus Eriugena, Anselm of Canterbury and Nicolas of Cusa, and it is argued that all three, in maintaining the ineffability of God, reach positions that are in effect forms of agnosticism. There is a paradox here: if God is inconceivable, is it not self‐refuting to talk about him at all, even to state his inconceivability? The final part of the paper examines the work of the nineteenth‐century poet Arthur Hugh Clough, two of whose poems, Hymnos Aumnos, and Qui Laborat Orat, explore the paradox of talking about the inconceivable Godhead. Clough gives eloquent expression to the idea that leaving God unnamed is not equivalent to disowning him. There is room for a devout agnosticism.  相似文献

Objective: An enhanced stress and coping model was used to explain depression among HIV‐positive women in healthcare and community settings where highly active anti‐retroviral treatment (HAART) was commonplace. Method: HIV‐infected women in four cities (N=978) were assessed, cross‐sectionally, for mental and physical health, stress, social support, and other background factors. Results: Self‐reported level of depressive symptomatology was high. Number of physical symptoms, illness intrusiveness, and perceived stress were positively associated with depressed mood, while coping self‐efficacy and social support were negatively associated. Stress mediated the effect of health status on depression and coping self‐efficacy mediated the effect of psychosocial resources on depression. Our enhanced stress and coping model accounted for 52% of variance in depressive symtpomatology. Conclusions: Interventions focused on improving coping self‐efficacy, bolstering social supports, and decreasing stress in the lives of HIV‐positive women may help to reduce the negative effects of HIV disease on mood.  相似文献

Two hundred twenty-one adults and young adults answered one of three versions of a questionnaire of opinion scales, which induced a comparison between three pairs of targets (husband and wife; husband and home helper; wife and home helper). After they evaluated the targets’ contributions to family work, participants judged whether the contributions were fair and satisfactory. Then participants’ degree of belief in sex differences and level of sexism were measured. Results show that spouses’ contributions are only judged satisfactory when wife was compared with home helper; male respondents’ reported that they believed more strongly in sex differences when husband and wife were compared; men’s and women’s level of benevolent sexism did not differ when husband was compared with home helper.  相似文献

This paper examines the integrated toy--both physical and virtual--as an essential resource for collaborative learning. This learning incorporates rehabilitation, training, and education. The data derived from two different cases. Pedagogical issues related to non-formal learning and open-ended features of design are discussed. Findings suggest that social, material, and expressive affordances constitute a base for an alterative interface to encourage children's play and learning.  相似文献
