In the prisoner's dilemma, self-interest clashes with collective interest. The way players resolve this conflict affects how others view them. Cooperators are seen as more moral than defectors, and, when there is no information about the other player's choice, cooperators and defectors are seen as equally competent. However, players who are defected against are seen as less competent, especially if they themselves cooperated (Experiments 1 and 2). Similarly, cooperators see themselves as more moral, but not as less competent, than defectors do (Experiments 3). Independent of concerns about reputation and self-image maintenance, evidential reasoning contributes to cooperative behavior. Players who project their own attitudes onto others are more likely to cooperate (Experiments 3). Compared with classic game theory, a theory of reputational concerns and evidential reasoning is better equipped to explain empirical patterns of choice behavior in social dilemmas. 相似文献

Previous research has indicated that many compulsive buyers also suffer from compulsive hoarding. The present work specifically examined hoarding in a compulsive buying sample. Sixty-six treatment-seeking compulsive buyers were assessed prior to entering a group therapy for compulsive buying using the Compulsive Buying Scale (CBS), the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS)-Shopping Version, the Compulsive Acquisition Scale (CAS), the German-CBS, the Saving Inventory-Revised (SI-R), the Maudsley Obsessive Compulsive Inventory (MOCI), the Barratt Impulsiveness Scale (BIS-11), and the Structured Clinical Interview for DSM-IV Axis I (SCID). Inclusion criteria were current problems with compulsive buying according to the proposed diagnostic criteria for compulsive buying by McElroy, Keck, Pope, Smith, and Strakowski [(1994). Compulsive buying: A report of 20 cases. Journal of Clinical Psychiatry, 55, 242-248]. Our results support the assumption that many but not all compulsive buyers suffer from compulsive hoarding. A significant association between the SI-R and the compulsive buying measures CBS, Y-BOCS-SV, German-CBS, and the CAS-Buy subscale was found, which is mostly caused by the SI-R subscale acquisition. The SI-R subscales clutter and difficulty discarding were more closely associated with the CAS-Free subscale and with obsessive-compulsive symptoms. Hoarding compulsive buyers reported more severe buying symptoms and obsessive-compulsive symptoms and presented with a higher psychiatric co-morbidity, especially any current affective, anxiety and eating disorder. Specific therapeutic interventions for compulsive buyers who also report compulsive hoarding appear indicated. 相似文献

The aim of this paper is to define a notion of supervenience which can adequately describe the systematic dependence of extrinsic
as well as of intrinsic higher-level properties on base-level features. We argue that none of the standard notions of supervenience—the
concepts of weak, strong and global supervenience—fulfil this function. The concept of regional supervenience, which is purported to improve on the standard conceptions, turns out to be problematic as well. As a new approach, we develop
the notion of property-dependent supervenience. This notion is founded on a criterion of relevance adapting the supervenience base to the considered higher-level properties
in a specific way, such that only features which are relevant to the instantiation of the higher-level properties under consideration
are taken into account. 相似文献

The dominant view in the field of lexical access in speech production maintains that selection of a word becomes more difficult as the levels of activation of nontarget words increase--selection by competition. The authors tested this prediction in two sets of experiments. First, the authors show that participants are faster to name pictures of objects (e.g., "bed") in the context of semantically related verb distractors (e.g., sleep) compared with unrelated verb distractors (e.g., shoot). In the second set of experiments, the authors show that target naming latencies (e.g., "horse") are, if anything, faster for within--category semantically close distractor words (e.g., zebra) than for within--category semantically far distractor words (e.g., whale). In the context of previous research, these data ground a new empirical generalization: As distractor words become semantically closer to the target concepts--all else being equal--target naming is facilitated. This fact means that lexical selection does not involve competition, and consequently, that the semantic interference effect does not reflect a lexical level process. This conclusion has important implications for models of lexical access and interpretations of Stroop-like interference effects. 相似文献

Most research on liking of persons and groups has been conducted within separate paradigms, but the implicit assumption has been that the same processes govern judgments of liking or disliking regardless of the nature of the target. Departing from this assumption, we suggest a dual-process hypothesis according to which people base their liking of a target person primarily on the desirability of the person's characteristics, whereas they base their liking of a group primarily on the degree of similarity between the group and themselves. To test this hypothesis, participants were presented with either positively or negatively valenced sketches that either described an individual person or a group of people. Path analyses revealed that liking of a person was best predicted by desirability ratings, whereas liking of a group was best predicted by similarity ratings. Implications of these findings for stereotype maintenance are discussed. © 1998 John Wiley & Sons, Ltd. 相似文献

The paper analyzes the circumstances under which Bruno Bettelheim's (1903–1990) well-known paper, “Individual and Mass Behavior in Extreme Situations” (1943) came to be written and discusses its central arguments. The authors compare Bettelheim's analysis of the Nazi concentration camps with the interpretations of other authors, particularly those who had experienced the camps themselves, and identify areas of divergence. They also note the later modifications Bettelheim introduced in his own theories on occasions when the original article was reprinted or revised. In conclusion, we investigate the ways in which Bettelheim's analysis of the camps has been received and cited by later scholars. © 1997 John Wiley & Sons, Inc. 相似文献

This study was designed to explore relations of emotional empathy (two scales) with aggression and violence (three scales). An initial study investigated validity of one of the violence scales, the Risk of Eruptive Violence Scale (REV), by comparing individual REV scores with individual histories of criminal violence for a sample of incarcerated juveniles. Validity of the REV was supported by a very strong correlation of .71 between REV scores and the amount of criminal violence in this homogeneous sample. The second study yielded positive intercorrelations among measures of aggression and violence, positive intercorrelations among measures of emotional empathy, and negative correlations (ranging from –.22 to –.50, P < .05) of measures of aggression and violence with measures of emotional empathy. Analyses of the five scales in terms of the Pleasure-Arousability-Dominance (PAD) Temperament Model helped explain similarities of the emotional empathy scales with other individual difference measures of prosocial orientation (e.g., affiliation). PAD analyses also explained some paradoxical effects of experimental "empathy arousal" on aggression toward victims. Aggr. Behav. 23:433–445, 1997. © 1997 Wiley-Liss, Inc. 相似文献
