Decisions to allocate rewards to ingroup and outgroup members are under the dual pressures of equity and intergroup bias. This study examined variations in equity and bias resulting from the incongruity and salience of intergroup status. Incongruity arose from a mismatch between high subjective and low accorded status. Congruity occurred when subjective status and accorded status were both high or both low. By pairing school classes with known subjective and accorded statuses, an incongruous and a congruous status setting were derived naturally. The setting was made either salient or nonsalient experimentally. It was hypothesized that bias would progressively increase, and equity would progressively decrease, with incongruity and salience. Each set of hypotheses was partially supported. Further data analysis showed a robust tendency to under-reward both ingroup and outgroup members. This interpersonal negativity bras was shown by incongruous status allocators either when rewarding superior performance or in the salient condition. Apparently, it served to safeguard personal rather than social identity. The implications for equity and social identity theories were discussed. 相似文献

We investigated the relationship between ambient temperature and prosocial behaviour in real-life settings. It was guided by two mechanisms of opposite predictions, namely (1) higher temperatures decrease prosociality by harming well-being, and (2) higher temperatures increase prosociality by promoting the embodied cognition of social warmth. In Study 1, U.S. state-level time-series data (2002–2015) supported the first mechanism, with higher temperatures predicting lower volunteer rates through lower well-being. Study 2 furthered the investigation by probing the relationship between neighbourhood temperature and civic engagement of 2268 U.S. citizens. The data partially supported the well-being mechanism and reported findings contradictory to the social embodiment mechanism. Higher temperatures predicted lower interpersonal trust and subsequently lower civic engagement. The unexpected finding hinted at a cognitive effect of heat and a compensatory mechanism in social thermoregulation. We discussed the findings regarding their methodological strengths and weaknesses, with cautions made on ecological fallacies and alternative models. 相似文献

The present research focused on power processes in a simulated organizational structure consisting of three hierarchical levels occupied by different numbers of mules and females. Subjects were presented with a chart showing the organizational hierarchy of which they were a member placed at the lowest level, and asked to nominate any person for the leader position vacated by the current incumbent. The results of Experiment I (n = 88 Dutch male and female university students) showed that male subjects strongly overnominated themselves, whereas a majority of the female subjects nominated either self or another female. Of the others that were nominated by both males and females, almost all were occupants of positions immediately below the leader position, indicating the normative influence of a bureaucratic rule of leader succession. Experiment 2 was a replicational study carried out in a different culture (n = lOl Polish male and female university students). Polish subjects adhered to the bureaucratic rule more strongly than their Dutch counterparts, and both females and males nominated mostly males. Results are discussed with reference to gender self-stereotypes and cultural differences. 相似文献

The essay examines the argument advanced by E.D. Hirsch, Jr., for instituting ‘cultural literacy’ as a fundamental priority of schools. A number of confusions and equivocations in Hirsch's reasoning are identified, and the propensity of his project to indoctrinate is exposed. Among the features of Hirsch's argument shown to be troubling are his shifting construal of ‘language’, his inconsistency about the requirements of cultural literacy, and his uncritical relation to traditional images of the American past and present. The upshot is to raise the question why Hirsch's project has elicited wide support and praise. 相似文献

The cellular expression of S-100β protein is upregulated in Alzheimer's disease and in Down's syndrome, and this protein has been implicated in memory-related processes in laboratory animals. However, the possibility that the α subunit of S-100 is also involved in memory has not yet been examined. In the present study, day-old black Australorp white Leghorn cockerel chicks (Gallus domesticus) received injections of monoclonal antisera to S-100α (1:50) or S-100β (1:500) into each hemisphere immediately after training on a one-trial passive avoidance task. The chicks displayed significantly lower retention levels than control birds that had been injected with antisera to carbonic anhydrase, or with saline (p< .01). S-100α antisera had an amnestic effect when injected between 0 and 20 min after training, with memory deficits occurring from 30 min postlearning, at the point of transition between the A and the B phases of the Gibbs-Ng intermediate memory stage. By contrast, the S-100β antisera needed to be injected either 5 min before or immediately after training and produced amnesia 10 min earlier, at the start of the A phase of the intermediate memory stage. We conclude that the two subunits of the S-100 protein are required at different points in the sequence of events leading to the consolidation of passive avoidance memory. 相似文献

How can we explain that an assertion on something perceived can be understood in the same manner by somebody who cannot perceive that scene? This problem bases the interest in computational linguistics in how listener modeling could possibly be harmonized with reference semantics. Mental images substituting real perception appear as a way out. The architecture of the listener model has to be adapted to the creation and use of such pictorial data structures. Furthermore, the relation between the latter and a verbal (i. e., propositional) representation must be understood. The resulting architecture of a listener model with reference semantics can be employed to solve communicational problems from three general classes in a better way, as is demonstrated by an example implementation. 相似文献
