In this paper, we report an original study of the relationships between self-attributed need for uniqueness and several consumer dispositions. The results indicate that the self-attributed need for uniqueness is related to consumers' desires for scarce, innovative, and customized products and to consumers' preferences for unusual shopping venues, but not to consumers' susceptibilities to normative influence. Moreover, we find that these relationships are mediated by a latent variable reflecting individual differences in the tendency to pursue uniqueness through consumption. The theoretical and practical implications of these results are discussed along with directions for future research. 相似文献

This study examined the effects of information about a landlord's personality on juror judgments for a landlord-tenant civil trial. The personality information manipulated was specifically relevant to destructive acts. Alternative versions of witness testimony were used to describe a landlord either high or low on need for power. treating people as objects, and negative life themes. This information strongly influenced aspects of the schema for this case constructed by the individual mock jurors. Destructive personality information caused dislike of the landlord and lowered the credibility of his story. If the landlord treated people as objects, the credibility of the tenant's story and positive evaluations of the tenant increased. Juror judgments about relative fault were strongly shifted by destructive personality information. An empirical model for juror decisions indicated a dynamic interplay of story components and fault judgments. 相似文献

The present study uses attribution theory to identify factors that may lead to unfavorable emotional reactions toward patients with schizophrenia and to highlight factors that may contribute to the observed inverse relationship between industrial status of a country and schizophrenia outcome. University students from Mexico and the U.S., 2 countries differing in industrial status, served as participants. Eighty-eight Mexicans from Guadalajara and 88 Anglo Americans from Los Angeles, California read vignettes of a patient described to meet DSM-IV criteria for schizophrenia. In one vignette, the patient's disorder was characterized by predominantly positive symptoms (e.g., hallucinations, delusions), whereas in the other vignette negative symptoms (e.g., social withdrawal, apathy) predominated. In support of an attributional approach, negative symptoms were associated with greater perceived control than were positive symptoms. Correspondingly, negative symptoms were found to provoke more intense negative affect and less intense positive affect than were positive symptoms. Some national and gender differences were also found. 相似文献

This research examined whether previously documented social benefits associated with physical attractiveness would influence the decision to request proof of legal age for the purchase of alcohol. Undergraduates were presented with a photograph of a highly attractive or less attractive member of the opposite gender that they diddid not expect to meet. Results indicated that the opportunity to interact with a highly attractive member of the opposite gender significantly reduced the chances that the target would be asked to provide proof of legal age. Physical attractiveness was positively related to perceptions of age in the perception of male targets, hut not for females. The implications of these findings for restricting alcohol availability among minors are considered. 相似文献

The relation between memory and attention has been of long-standing interest. Eich (1984) made an important discovery of implicit but not explicit memory for contextually determined homophones (e.g., taxi-FARE) presented in a channel to be ignored within a selective listening procedure. However, his slow rate of presentation of shadowing task materials may have allowed frequent attention shifts to the allegedly ignored channel. With a direct replication of Eich’s timing parameters, we reproduced his results, but when the attended channel was presented twice as fast as Eich’s, implicit memory for the to-be-ignored words vanished. Our results contradict claims of extensive semantic processing of unattended auditory information in this task. 相似文献

Religion can be defined narrowly as belief in anthropomorphic supernatural beings. For Levy-Bruhl this meant that prelogical ‘mystic participation’ preceded true religion. For Donald Wiebe and others it means that philosophical-scientific rationality has been struggling to replace religion since the axial age. A broader definition of religion interprets rational post-axial theology as a development within religion, not a replacement of true religion. Both definitions are legitimate. The narrow definition highlights a tendency to superstition in religion. The broader definition recognizes the possibility of an evolution of religious thought. 相似文献

11beta-hydroxysteroid dehydrogenase type 1 (11beta-HSD-1) catalyses the interconversion of active cortisol and corticosterone with inert cortisone and 11-dehydrocorticosterone, thus regulating glucocorticoid access to intracellular receptors. In rats, chronic glucocorticoid excess or stress increases 11beta-HSD-1 in the hippocampus, producing suggestions that it may attenuate the deleterious effects of chronic glucocorticoid excess. However, 11beta-HSD-1 predominantly catalyses 11beta-reduction in the intact liver and hippocampal cells, thus regenerating active glucocorticoids from inert substrate. We studied 11beta-HSD activity in the tissues of male tree shrews following 28 days of sustained psychosocial stress or exogenous administration of cortisol. In the hippocampus, chronic psychosocial stress attenuated 11-HSD-1 activity (69 +/- 9% of control), whereas cortisol alone had no effect. In the liver, both chronic stress and cortisol administration decreased 11beta-HSD-1 activity (47 +/- 11% and 49 +/- 4% fall, resp.). Attenuation of 11beta-HSD-1 within tissues may reflect a homeostatic mechanism designed to minimise the adverse effects of prolonged stress and/or glucocorticoid excess. 相似文献
