Six experiments investigated the effect of the promotion criterion in simulated academic promotion decisions. In total, 547 undergraduate students and 33 university faculty members rated a promotion application, and some also indicated their decisions to support or to reject it. Performance ratings were reliably affected by the criterion, with a high criterion resulting in higher ratings than a low criterion, and this criterion effect was found regardless of the evaluator's expertise, whether he or she took the role of an independent assessor or the line manager to the applicant, or whether the criterion was provided by the experimenter or randomly generated by the participant. The criterion also affected the level of support for a candidate when the position applied for was perceived to be extremely competitive, or when a lesser position was considered at a later time. These results provide evidence that the use of a criterion, a fairly common practice in decision‐making processes, may bias performance evaluations, which in turn may have ripple effects that affect the outcome of a chain of events. Our results also shed light on the possible mechanisms that underlie the rating biases in performance appraisal. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

The article examines the role of dual identification with both the ethnocultural ingroup and the society of residence in the politicization of migrants. The researchers employed a longitudinal and comparative research design with members of the two largest, but sociologically very different, migrant groups in Germany as research participants (i.e. Turkish migrants and Russian migrants). In line with prior work that has shown that, among members of aggrieved groups, dual identity functions as a politicized collective identity, we found that dual identification fostered political engagement among Turkish migrants. In contrast, Russian migrants reported no substantial grievances, and dual identification negatively affected their subsequent political engagement. The contributions of these findings to an articulation of research on politicization with research on intergroup conflict and a more comprehensive understanding of political phenomena driven by dual identification are discussed.

Visual object perception is usually studied by presenting one object at a time at the fovea. However, the world around us is composed of multiple objects. The way our visual system deals with this complexity has remained controversial in the literature. Some models claim that the ventral pathway, a set of visual cortical areas responsible for object recognition, can process only one or very few objects at a time without ambiguity. Other models argue in favor of a massively parallel processing of objects in a scene. Recent experiments in monkeys have provided important data about this issue. The ventral pathway seems to be able to perform complex analyses on several objects simultaneously, but only during a short time period. Subsequently only one or very few objects are explicitly selected and consciously perceived. Here, we survey the implications of these new findings for our understanding of object processing.  相似文献

Why is language the way it is? How did language come to be this way? And why is our species alone in having complex language? These are old unsolved questions that have seen a renaissance in the dramatic recent growth in research being published on the origins and evolution of human language. This review provides a broad overview of some of the important current work in this area. We highlight new methodologies (such as computational modeling), emerging points of consensus (such as the importance of pre-adaptation), and the major remaining controversies (such as gestural origins of language). We also discuss why language evolution is such a difficult problem, and suggest probable directions research may take in the near future.  相似文献

By taking the MAX from their inputs, neurons in the ventral visual pathway might preserve their selectivity even when stimulated with natural scenes. This computational hypothesis has received recent direct physiological evidence from recordings of V4 neuronal responses, in a recent study by Gawne and Martin (2002). Object vision might rely more heavily on parallel processing than generally thought.  相似文献

Building on an articulation of two influential social-psychological approaches, this chapter suggests a dual-pathway model of collective action. In line with traditional social movement research, one pathway concerns the calculation of the costs and benefits of participation; the other pathway concerns collective identification processes as suggested by the social identity approach. Whereas the model's calculation pathway can be interpreted in terms of group members' instrumental involvement motivated by specific extrinsic rewards, the identification pathway seems to represent intrinsic involvement based on the internalisation of group-specific behavioural standards. Both pathways seem to operate independently, such that group members are pulled towards collective action by the expected external rewards while simultaneously being pushed towards this activity by an inner obligation to enact their (politicised) collective identity. Further applications of this model to forms of collective action other than social movement participation (e.g., collective helping) are discussed.  相似文献

The present study sought to examine the various stressors faced, and associated coping strategies employed, by five single-handed sailors entered into the 2006/2007 Velux 5 Oceans round-the-world race. Interviews conducted with the skippers were transcribed and then deductively and inductively content analyzed. Skippers revealed organizational (e.g., environmental conditions, isolation, sleep deprivation), competitive (e.g., lack of progress, yacht-related problems), and personal (e.g., family-related issues) stressors. Strategies used to deal with these demands included problem- (e.g., prioritized sequential thinking), appraisal- (e.g., rationalizing situations), emotion- (e.g., using available communications), and approach-focused coping (e.g., “what if” scenario planning). The present study proposes that future research should examine more closely the stressor-coping strategy relationship to guide the development of successful coping interventions.  相似文献

We examined the dilemmas posed by the involvement of expert witnesses in court cases and the institutional constraints on the ethics of expert testimony. The causes for the incorporation of bad science into legal decisions, potential solutions to this dilemma, and the limitations of these solutions are considered. We concluded that law, science, and experts must respond to the problems posed by expert witnessing.  相似文献
