The aim of the study was to explore whether temporal information processing can interfere with performance of a non-temporal task. A new methodology based on the Garner paradigm was employed. Participants were asked to classify two-dimensional stimuli according to either length or duration, with and without variation in the other (task-irrelevant) dimension. Garner interference was detected only with respect to classification by length when irrelevant variation in duration was present. Stroop interference was detected only in classification by length across compatible and non-compatible values of length and duration. Classification by length took more time when done with variation in duration than when duration was constant. Classification by length also took more time when length and duration were not compatible than when they were compatible. The findings indicate that the processing of duration is similar to the processing of other perceptual dimensions. The processing of duration consumes attentional resources and can interfere with the processing of other perceptual dimensions. The findings support attentional models of prospective duration judgment. 相似文献

Four studies conducted in various organizations in Italy, employing contemporaneous and longitudinal designs, tested hypotheses relating 2 personality constructs—need for cognitive closure ( Kruglanski & Webster, 1996 ) and locomotion tendency ( Higgins, Kruglanski, & Pierro, 2003 ; Kruglanski et al., 2000 )—to individuals’ ability to successfully cope with organizational change. Across diverse organizational settings, populations studied, types of organizational change implemented, and measures of coping with change, we found that need for closure was negatively related, and locomotion tendency was positively related, to coping with change. We also found that the negative relation between need for closure and coping was attenuated where organizational climate is supportive of change, and that degree of successful coping with change determines post‐change work attitudes. 相似文献

In a sample of 1287 adolescents, it appeared that weekly exercise facilitates a variety of goals; particularly those related to being or remaining healthy, feeling relaxed, not being bored, feeling physically good, not being stressed, and attaining high achievements were endorsed. Sedentary and active adolescents reported a similar order of 10 specific goals with respect to the likelihood of being positively influenced by exercise. The frequency of reported facilitation for each of the goals, however, was higher among the active adolescernts. This suggests that the more exercise is incorporated in daily life, the more it can be regarded as an integral part of the personal goal structure. 相似文献

Six experiments tested a dilution model of self-regulation, whereby increasing the number of goals (e.g., building muscles and losing weight) that a single means (e.g., exercising) can satisfy reduces the perception of its instrumentality with respect to each goal. The authors found that an increase in the number of simultaneous, salient goals that can be satisfied via a single means weakens the associative strength between that means and each individual goal, and as a result, individuals perceive the means as less effective for the attainment of each goal. Consequently, means that are connected to multiple (vs. single) goals are less likely to be chosen and pursued when only one of these goals is activated. 相似文献

This article examines the role of personality dispositions as determinants of people's reactions to threats to social identity. It is argued that since individuals characterized as high field-dependents have a greater tendency to anchor their identity in the social group than low field-dependents, they will be more affected by threats to social identity, especially when the context is framed as an intergroup context. Threat to social identity was manipulated by inducing intergroup similarity, and intergroup differentiation was measured. The first experiment assessed the hypothesis with minimal groups. The second experiment assessed it with real groups (two rival schools). Findings provided support for the hypotheses. The discussion centers on the role of personality dispositions in the social identity perspective. 相似文献

ABSTRACT— In this research, we varied the composition of 4-member groups. One third of the groups consisted exclusively of "locomotors," individuals predominantly oriented toward action. Another third of the groups consisted exclusively of "assessors," individuals predominantly oriented toward evaluation. The final third of the groups consisted of a mix of locomotors and assessors. We found that the groups containing only locomotors were faster than the groups containing only assessors, and the groups containing only assessors were more accurate than the groups containing only locomotors. The groups containing a mix of assessors and locomotors were as fast as the groups containing only locomotors and as accurate as the groups containing only assessors. These results echo findings at the individual level of analysis, and suggest that the testing and action components of operating systems independently contribute to performance both intra- and interpersonally. 相似文献

The present study examined the influence of two regulatory mode concerns—a locomotion concern with movement from state to state and an assessment concern with making comparisons—on choices between immediate and delayed (from 2 to 6 weeks) money rewards. Regulatory mode orientation was induced by means of a priming procedure. We predicted that the choices in the assessment condition would be less impulsive and more far‐sighted than those in the locomotion condition. After taking into account the effects of amount of early reward, length of delay and increase in delayed reward—all of which were in the direction of previous studies—this regulatory mode prediction was supported. Our findings suggest that it might be possible to induce more far‐sighted (or economically rational) inter‐temporal choices by means of instructions that induce an assessment orientation independent of stable inter‐individual differences in discount rate.

Nano-ethics as NEST-ethics: Patterns of Moral Argumentation About New and Emerging Science and Technology 总被引:6,自引:3,他引:3
There might not be a specific nano-ethics, but there definitely is an ethics of new & emerging science and technology (NEST),
with characteristic tropes and patterns of moral argumentation. Ethical discussion in and around nanoscience and technology
reflects such NEST-ethics. We offer an inventory of the arguments, and show patterns in their evolution, in arenas full of
proponents and opponents. We also show that there are some nano-specific issues: in how size matters, and when agency is delegated
to smart devices. Our overall approach is a pragmatist ethics, and we conclude that struggle (and learning) might be more
productive than models emphasizing consensus.

We tested a model in which perceived workload and autonomy were hypothesised to mediate the effects of work hours and caseload on physician burnout. The study was based on data provided by 890 specialists representing six medical specialties. We used structural equation modeling to test our hypotheses. Controlling for the effects of gender, seniority, and the specialists' academic affiliation, we found that the study data fit the hypothesised model—reflecting these hypotheses—quite well. As expected, workload predicted higher levels of global burnout and physical fatigue, while autonomy predicted lower levels of global burnout. Work hours and caseload predicted global burnout only indirectly, via their effects on either perceived workload or autonomy. These findings suggest that public policies, designed to reduce physician work hours in order to reduce burnout and improve patients' safety, should take into account physician perceived workload and autonomy. Nous avons mis à l'épreuve un modèle centré sur l'hypothèse selon laquelle la charge de travail perçue et l'autonomie régulaient l'impact de la durée du travail médical et administratif sur le burnout des médecins. La recherche a exploité des données fournies par 890 spécialistes relevant de six spécialités médicales. On a fait appel à une modélisation en équations structurales pour valider nos hypothèses. En contrôlant l'action du genre, de l'âge et du type de spécialité, il est apparu que les données correspondaient parfaitement au modèle hypothétique. Comme prévu, la charge de travail prédisait des niveaux plus élevés de burnout global et de fatigue physique, alors que l'autonomie débouchait sur des niveaux plus faibles de burnout global. La durée du travail ne prédisait qu'indirectement le burnout global, par l'entremise des retombées sur la charge de travail perçue et l'autonomie. Ces résultats montrent que la réglementation publique qui envisage de réduire le temps de travail des médecins dans le souci d'atténuer le burnout et d'améliorer la sécurité des malades devrait prendre en considération la charge de travail perçue et l'autonomie des médecins. 相似文献

As an extension of Lastovicka's four-mode components analysis ann-mode components analysis is developed. Using a convenient notation, both a canonical and a least squares solution are derived. The relation between both solutions and their computational aspects are discussed.The first draft was written while Wansbeek was with the Netherlands Central Bureau of Statistics. We thank Jaap Verhees for performing the computations and for many discussions on the subject, John Lastovicka for kindly making available his data to us, and the Editor, the referees, Jeroen Weesie and Pieter Kroonenberg for their useful comments. 相似文献
