ABSTRACT— Cooperation often fails to spread in proportion to its potential benefits. This phenomenon is captured by prisoner's dilemma games, in which cooperation rates appear to be determined by the distinctive structure of economic incentives (e.g., $3 for mutual cooperation vs. $5 for unilateral defection). Rather than comparing economic values of cooperating versus not ($3 vs. $5), we tested the hypothesis that players simply compare numeric values (3 vs. 5), such that subjective numbers (mental magnitudes) are logarithmically scaled. Supporting our hypothesis, increasing only numeric values of rewards (from $3 to 300¢) increased cooperation ( Study 1 ), whereas increasing economic values increased cooperation only when there were also numeric increases ( Study 2 ). Thus, changing rewards from 3¢ to 300¢ increased cooperation rates, but an economically identical change from 3¢ to $3 elicited no gains. Finally, logarithmically scaled reward values predicted 97% of variation in cooperation, whereas the face value of economic rewards predicted none. We conclude that representations of numeric value constrain how economic rewards affect cooperation. 相似文献

For years, the authors of the best-selling guide to India, Lonely Planet, has shaped the perspectives of many travellers. This article considers how religion is constructed as a category and how it is made relevant to travellers. I argue that ‘religion’ comes in two versions, one pertaining to the Indian hosts and one to travellers. Religion is based on tradition, faith and historical institutions, whose members, rituals and sacred sites are of interest to travellers. Spirituality has to do with the personal development of travellers and is exclusively referred to as philosophy. 相似文献

In this study, the authors examined relations among adult attachment orientations, maladaptive problem coping styles, and a composite measure of current distress within a sample of 55 undergraduates (17 men, 38 women). Results indicated that each adult attachment orientation and each problem coping style measure was related in expected directions to students' distress. In addition, problem coping styles largely mediated the impact of insecure adult attachment orientations on distress. Implications of our findings to advancing an attachment theory‐informed perspective on college student coping, distress, and intervention are discussed. 相似文献

This study used conditional risk assessments to examine the role of behavioral experiences in risk judgments. Adolescents and young adults (ages 10-30; N = 577) were surveyed on their risk judgments for natural hazards and behavior-linked risks, including their personal experiences with these events. Results indicated that participants who had experienced a natural disaster or engaged in a particular risk behavior estimated their chance of experiencing a negative outcome resulting from that event or behavior as less likely than individuals without such experience. These findings challenge the notion that risk judgments motivate behavior and instead suggest that risk judgments may be reflective of behavioral experiences. The results have implications for health education and risk communication. 相似文献

This study reports on a three-semester model project designed to assess the impact of enriched content related to Women's and Gender Studies on students enrolled in an undergraduate ecology course. The two constructs of interest were (a) students' attitudes toward women in science and society and (b) students' assessment of the classroom climate for women. The data included 398 matched pretest and posttest survey responses from a control group, a minimal enrichment group, and an increased enrichment group. Findings indicated that, although small course revisions did not influence students' attitudes toward women in science and society, such revisions had a positive influence on students' assessments of the classroom climate. 相似文献
