What does it take to find a member of a different race attractive? In this research, we suggest that for Whites, attraction to Asians may be based, in part, on stereotypes and variations in Asians' racial appearance. Study 1 reveals that Asians are stereotyped as being more feminine and less masculine than other racial groups-characteristics considered appealing for women but not for men to possess. Study 2 examines how variation in racial appearance, phenotypic prototypicality (PP), shapes the degree to which Asians are gender stereotyped and how PP relates to perceptions of attractiveness. Higher PP Asian men are perceived as being less masculine and less physically attractive than lower PP Asian men. These findings inform theory on how within-group variation in racial appearance affects stereotyping and other social outcomes.  相似文献

Scholars have long assumed that as workers spend more time at work fewer hours are available for their non-work lives leading to negative effects in both domains, and most studies examining the impact of work hours on work and life domains have supported this viewpoint. However, the majority of these studies have used one-dimensional measures of work–family conflict (WFC) and family–work conflict (FWC) on homogenous samples which included primarily married managers and professionals with children. Further, despite calls to examine non-linear relationships between work hours and WFC and FWC, few studies have done so. This study uses multi-dimensional measures to examine the linear and non-linear (quadratic) effects of work hours on WFC and FWC in a heterogeneous sample and examines the moderating effects of several work and family characteristics on these relationships. The findings indicate that whereas work hours have a linear relationship with WFC, the relationship between work hours and FWC is curvilinear. Managerial support was found to moderate the relationship between work hours and one dimension of FWC. Number of children moderated the relationships between work hours and WFC and another dimension of FWC.  相似文献

Spirituality plays an important role in cancer coping among African Americans. The purpose of this study was to report on the initial psychometric properties of instruments specific to the cancer context, assessing the role of spirituality in coping. Items were developed based on a theoretical model of spirituality and qualitative patient interviews. The instruments reflected connections to self, others, God, and the world. One hundred African American cancer survivors completed the instruments by telephone. The instruments showed adequate internal reliability, mixed convergent validity, discriminant validity, and interpretable factor structures.  相似文献

Productive tests are unsuitable for measuring infants' earliest understanding of pretence, because performance demands may render infants unable to produce the actions required to pass the test. Recently, Onishi, Baillargeon and Leslie (2007) used the violation-of-expectation (VOE) paradigm as a measure of infants' understanding of others' pretence that is free from such performance demands. They found that 15-month-old infants looked longer at an Unexpected event in which an actor pretended to pour into one cup but pretended to drink from another cup, compared to pretending to pour and drink with the same cup. On this basis, they argued that 15-month-old infants expect others' pretence to be consistent, demonstrating their understanding of others' pretence. However, infants may have responded to expectations they had about familiar action sequences, rather than to pretence per se. To test this hypothesis, the current study firstly replicated Onishi et al.'s results in a sample of 28 typically developing 15-month-old infants, and then added a condition using closely matched real versions of their pretend VOE tasks. It was found that infants looked longer at unexpected events, whether or not the events were real or pretend. It was concluded that 15-month-old infants may look longer at pretend events due to violations of expectations they have about familiar action sequences, rather than because they understand others' pretence behaviour.  相似文献

This Psychology of Women Quarterly special issue argues that the goals of the Decade of Behavior to foster a healthier, safer, better educated, more prosperous, and more democratic nation cannot be achieved without contributions from feminist psychology. Its individual articles reflect feminist perspectives and provide examples of how feminist perspectives can inform behavioral and social research within Decade domains. In this overview, we outline the challenges that gender poses to achieving Decade goals, and discuss four cross-cutting feminist principles for research to address those challenges: Inclusiveness and Diversity, Context, Power and Privilege, and Activism. We discuss specific limitations of traditional research, and emphasize the need for new models that view the world in more complex, context-based ways. We underscore the importance of generating new, diversity-mindful research questions and of developing and accepting new methods to answer them. We discuss policy implications, stressing the need for activism. We hope this work will encourage the expansion of feminist scholarship in the new millennium and be helpful to researchers, educators, and policymakers in working to achieve the goals of the Decade of Behavior.  相似文献

Expectancy and efficacy theories provide the foundation for the development of a measure of sport confidence. The Carolina Sport Confidence Inventory (CSCI) was conceptualized as a three-factor model represented by dispositional optimism, perceived competence, and perceived control. Two independent studies supported a two factor (dispositional optimism and perceived competence) 13- item model for the CSCI. The first study utilized exploratory factor analytic techniques, concurrent validity, social desirability assessment, internal consistency, and test-retest reliability to establish the psychometric properties of the CSCI. Study II employed confirmatory factor analytic techniques with a sample of 123 intercollegiate varsity athletes along with measures of convergent validity to provide further support for the two factor model and the psychometric properties of the instrument.  相似文献

Chronic stress has detrimental effects on hippocampal integrity, while environmental enrichment (EE) has beneficial effects when initiated early in development. In this study, we investigated whether EE initiated in adulthood would mitigate chronic stress effects on cognitive function and hippocampal neuronal architecture, when EE started one week before chronic stress began, or two weeks after chronic stress onset. Adult male Sprague Dawley rats were chronically restrained (6h/d) or assigned as non-stressed controls and subdivided into EE or non-EE housing. After restraint ended, rats were tested on a radial arm water maze (RAWM) for 2-d to assess spatial learning and memory. The first study showed that when EE began prior to 3-weeks of chronic stress, EE attenuated chronic stress-induced impairments in acquisition, which corresponded with the prevention of chronic stress-induced reductions in CA3 apical dendritic length. A second study showed that when EE began 2-weeks after the onset of a 5-week stress regimen, EE blocked chronic stress-induced impairments in acquisition and retention at 1-h and 24-h delays. RAWM performance corresponded with CA3 apical dendritic complexity. Moreover, rats in EE housing (control or stress) exhibited similar corticosterone profiles across weeks, which differed from the muted corticosterone response to restraint by the chronically stressed pair-housed rats. These data support the interpretation that chronic stress and EE may act on similar mechanisms within the hippocampus, and that manipulation of these factors may yield new directions for optimizing brain integrity and resilience under chronic stress or stress related neuropsychological disorders in the adult.  相似文献

Two studies using an ABA design examined the Extinction and renewal of conditioned barpress suppression. Following lights-off and foot shock pairings in Context A, rats were placed in Context B and were given either a standard counterconditioning procedure where the lights-off CS was paired with a novel food US delivered freely or a modified counterconditioning procedure where CS-US pairings only occurred if the rat earned the US by performing a required behavior during the CS. Results indicated that the modified counterconditioning procedure thwarted ABA renewal but the conventional counterconditioning procedure did not reduce ABA renewal any more than nonreinforced exposure to the CS alone. Furthermore, the response required during the modified counterconditioning procedure could be one used as a baseline response during Acquisition of fear or it could be a novel response. Implications of the results for theories of Extinction and renewal of fear are discussed.  相似文献
