Fostering group identification and creativity in diverse groups: the role of individuation and self-verification 总被引:4,自引:0,他引:4
Swann WB Kwan VS Polzer JT Milton LP 《Personality & social psychology bulletin》2003,29(11):1396-1406
A longitudinal study examined the interplay of identity negotiation processes and diversity in small groups of master's of business administration (MBA) students. When perceivers formed relatively positive impressions of other group members, higher diversity predicted more individuation of targets. When perceivers formed relatively neutral impressions of other group members, however, higher diversity predicted less individuation of targets. Individuation at the outset of the semester predicted self-verification effects several weeks later, and self-verification, in turn, predicted group identification and creative task performance. The authors conclude that contrary to self-categorization theory, fostering individuation and self-verification in diverse groups may maximize group identification and productivity. 相似文献

Few studies have examined whether non-human tool-users understand the properties that are relevant for a tool's function.
We tested cotton-top tamarins (Saguinus oedipus) and rhesus macaques (Macaca mulatta) on an expectancy violation procedure designed to assess whether these species make distinctions between the functionally
relevant and irrelevant features of a tool. Subjects watched an experimenter use a tool to push a grape down a ramp, and then
were presented with different displays in which the features of the original tool (shape, color, orientation) were selectively
varied. Results indicated that both species looked longer when a newly shaped stick acted on the grape than when a newly colored
stick performed the same action, suggesting that both species perceive shape as a more salient transformation than color.
In contrast, tamarins, but not rhesus, attended to changes in the tool's orientation. We propose that some non-human primates
begin with a predisposition to attend to a tool's shape and, with sufficient experience, develop a more sophisticated understanding
of the features that are functionally relevant to tools. 相似文献

The traditional requirements upon the waging of a just war are ostensibly independent, but in actual practice each tenet is subject ultimately to the interpretation of a legitimate authority, whose declaration becomes the necessary and sufficient condition. While just war theory presupposes that some acts are absolutely wrong, it also implies that the killing of innocents can be rendered permissible through human decree. Nations are conventionally delimited, and leaders are conventionally appointed. Any group of people could band together to form a nation, and any person could, in principle, be appointed the leader of any nation. Because the just war approach assumes absolutism while implying relativism, the stance is paradoxical and hence rationally untenable. 相似文献

Pre-school children expect falling objects to travel in a straight line even when there are clear physical mechanisms that deviate the object's path (Hood, 1995). The current study set out to determine whether this expectancy is limited to humans. Cotton-top tamarins (Saguinus oedipus oedipus), a New World monkey species, were tested on Hood's (1995) experimental task where objects are dropped down a chimney connected by an opaque tube to one of three containers. Like human children, there was a significant tendency to search in the container underneath the chimney where the food was dropped on the first trial, even though aligned chimneys and containers were never connected. These search errors suggest that there may be a gravity bias that operates when both primate species fail to understand the constraints operating on object trajectories. Unlike human children however, tamarins were generally more likely to perseverate in making errors even though repeated testing and cost incentives were used. 相似文献

Patients with frontotemporal dementia (both behavioural variant [bvFTD] and semantic dementia [SD]) as well as those with Alzheimer's disease (AD) show deficits on tests of face emotion processing, yet the mechanisms underlying these deficits have rarely been explored. We compared groups of patients with bvFTD (n = 17), SD (n = 12) or AD (n = 20) to an age- and education-matched group of healthy control subjects (n = 36) on three face emotion processing tasks (Ekman 60, Emotion Matching and Emotion Selection) and found that all three patient groups were similarly impaired. Analyses of covariance employed to partial out the influences of language and perceptual impairments, which frequently co-occur in these patients, provided evidence of different underlying cognitive mechanisms. These analyses revealed that language impairments explained the original poor scores obtained by the SD patients on the Ekman 60 and Emotion Selection tasks, which involve verbal labels. Perceptual deficits contributed to Emotion Matching performance in the bvFTD and AD patients. Importantly, all groups remained impaired on one task or more following these analyses, denoting a primary emotion processing disturbance in these dementia syndromes. These findings highlight the multifactorial nature of emotion processing deficits in patients with dementia. 相似文献

In this paper we present a new framework of idealization in biology. We characterize idealizations as a network of counterfactual and hypothetical conditionals that can exhibit different ??degrees of contingency??. We use this idea to say that, in departing more or less from the actual world, idealizations can serve numerous epistemic, methodological or heuristic purposes within scientific research. We defend that, in part, this structure explains why idealizations, despite being deformations of reality, are so successful in scientific practice. For illustrative purposes, we provide an example from population genetics, the Wright-Fisher Model. 相似文献

Research has demonstrated that experiencing negative emotions at work can have adverse consequences for individuals and organizations. However, little research has explored why negative emotions can be associated with detrimental effects. To address this gap, the authors argue that it is critical to consider how emotions are experienced. Across two field studies (N= 876 and N= 136), the authors investigate the mediating role of toxic emotional experiences (TEEs) in the relationship between negative emotions and adverse outcomes. The three TEEs dimensions (i.e., psychologically recurring, disconnecting, and draining) are examined as well as the composite score. Results indicated that the TEEs composite mediated the relationship between negative emotions and psychological health, attitudes towards the organization, performance, and helping behaviours. Mixed results were found for the three TEEs dimensions. A number of theoretical implications are explored including the differential roles of negative emotions versus TEEs, the distinct effects associated with each of the TEEs dimensions, and the importance of exploring how emotions are experienced at work. Practical implications related to effectively managing negative emotions and preventing ‘toxic' experiences are also discussed. 相似文献

This study examines the effectiveness of bibliotherapy for low sexual desire among women, which is the most frequent sexual concern brought to counselors. Forty-five women responded to an advertisement for participation in a study on low sexual desire and were assigned to either the intervention or the wait-list control group. The intervention group completed the Hurlbert Index of Sexual Desire (HISD; Apt & Hurlbert, 1992) and the Female Sexual Function Index (FSFI; R. Rosen et al., 2000), read the self-help book under study in 6 weeks, and completed the measures a second time. The control group completed the same measures 6 weeks apart. Results demonstrated that the intervention group made statistically greater gains over time as compared with the control group on measures of sexual desire (HISD and FSFI Desire subscale), sexual arousal (FSFI Arousal subscale), sexual satisfaction (FSFI Satisfaction subscale), and overall sexual functioning (FSFI Total Score). A subset of participants in the intervention group participated in a 7-week follow-up study, and these participants maintained their gains in sexual desire and overall sexual functioning. Findings have important implications for future research on the efficacy of bibliotherapy generally and for low sexual desire specifically. Results also have vital implications for the treatment of low sexual desire. 相似文献

Although dehumanizing women and male sexual aggression are theoretically aligned, the present research provides the first direct support for this assumption, using the Implicit Association Test to assess two forms of female dehumanization: animalization and objectification. In Study 1, men who automatically associated women more than men with primitive constructs (e.g., animals, instinct, nature) were more willing to rape and sexually harass women, and to report negative attitudes toward female rape victims. In Study 2, men who automatically associated women with animals (e.g., animals, paw, snout) more than with humans scored higher on a rape-behavioral analogue, as well as rape proclivity. Automatically objectifying women by associating them with objects, tools, and things was also positively correlated with men's rape proclivity. In concert, the research demonstrates that men who implicitly dehumanize women (as either animals or objects) are also likely to sexually victimize them. 相似文献

This study explored the current psychological characteristics and criminal behavior history of individuals who retrospectively reported being bullies, bully-victims, victims, or controls (i.e. neither victims nor bullies) during their last 2 years of high school. College students (n = 960) completed measures of criminal thinking, aggression, psychopathy, and criminal behavior online. We predicted bullies and bully-victims would demonstrate the highest scores for criminal thinking, proactive aggression, psychopathy, and have the most criminal infractions. Bullies and bully-victims had significantly higher scores on criminal thinking, aggression, psychopathy, and criminal behaviors than victims or controls. Additionally, men were significantly higher in criminal thinking, aggression, psychopathy, and had more criminal acts than women. There were no gender by bully group interactions. Logistic regression analyses differentiated bully-victims from bullies. Bully-victims tended to be male, higher in criminal thinking, and higher in reactive aggression. In addition, bully-victims were distinct from victims, showing higher criminal thinking and higher proactive aggression. 相似文献
