Does face recognition involve face-specific cognitive and neural processes ('domain specificity') or do faces only seem special because people have had more experience of individuating them than they have of individuating members of other homogeneous object categories ('the expertise hypothesis')? Here, we summarize new data that test these hypotheses by assessing whether classic face-selective effects - holistic processing, recognition impairments in prosopagnosia and fusiform face area activation - remain face selective in comparison with objects of expertise. We argue that evidence strongly supports domain specificity rather than the expertise hypothesis. We conclude that the crucial social function of face recognition does not reflect merely a general practice phenomenon and that it might be supported by evolved mechanisms (visual or nonvisual) and/or a sensitive period in infancy.  相似文献

A model of coping with stress is proposed in which coping mediates the relationship among organizational stressors and personal characteristics, and job-related strains and organizational outcomes. Study results, based on a sample of professional salespeople, provide overall support for most of the hypothesized relationships among work-related stressors, personal characteristics, and coping styles. Findings also support the influence of emotion-focused coping on the psychological outcomes of emotional exhaustion and job-induced anxiety; which in turn are found to influence job satisfaction and intention to withdraw. While problem-focused coping had no effect on job-induced anxiety, problem-focused coping did effect emotional exhaustion, which in turn influences job satisfaction and intention to withdraw. Minor differences were found when the proposed model was applied to saleswomen versus salesmen. Overall, however, the model was robust across both genders.  相似文献

Each day, thousands of televised images of the workplace fill the airwaves through programs such as Law and Order, ER, and The Simpsons. Although communications research has suggested that the social reality of television is often accepted by high‐level viewers ( Perry & Roesch, 2004 ; Potter, 1994 ), management researchers have been slow to examine television as work socialization. This paper addresses possible concerns of scale and theoretical rigor through development of reliable scales based on televised content and the testing of relationships through an interdisciplinary framework. Regression results indicate that heavy television exposure may influence viewer perceptions regarding access to managers and resources. The results also indicate that non‐media work information can moderate this effect. Practical implications for managers are provided.  相似文献

Structural magnetic resonance imaging (MRI) studies of the human brain have reported evidence for sexual dimorphism. In addition to sex differences in overall cerebral volume, differences in the proportion of gray matter (GM) to white matter (WM) volume have been observed, particularly in the parietal lobe. To our knowledge there have been no studies examining the relationship between the sex differences in parietal lobe structure and function. The parietal lobe is thought to be involved in spatial ability, and particularly involved in mental rotation. The purpose of this study is to examine whether sex differences in parietal lobe structure are present, and if present to relate these differences to performance on the mental rotations test (MRT). We found that women had proportionately greater gray matter volume in the parietal lobe compared to men, and this morphologic difference was disadvantageous for women in terms of performance on the MRT. In contrast, we found that men compared to women had proportionately greater parietal lobe surface area, and this morphologic difference was associated with a performance advantage for men on mental rotation. These findings support the possibility that the sexual dimorphism in the structure of the parietal lobe is a neurobiological substrate for the sex difference in performance on the mental rotations test.  相似文献

To understand the role that Mexican origin parents play in their children's academic success, this study used structural equation modeling to evaluate the associations of parents' parenting practices (warmth, monitoring, harshness, and academic involvement) and cultural orientations (enculturation and acculturation) with their adolescents' grades, classroom behavior, and association with peers who get into trouble at school. Data were obtained from teachers, mothers, fathers, and male and female adolescents in 560 Mexican origin families living in the southwest U.S. Results indicated that mothers' and fathers' parenting practices and cultural orientations were linked to adolescents' academic outcomes. However, there were differences for boys and girls. Results are discussed in relation to parent and adolescent gender roles and implications for intervention.  相似文献

Purpose  In this study we evaluate competing models of the direct and indirect effects of work interference with family (WIF) and family interference with work (FIW) on two turnover intentions relevant to scientists and engineers: (i) leaving R&D for non-R&D work within the same organization and (ii) leaving one’s organization for another one. Design/methodology/approach  A cross-sectional design was used. Our sample consists of almost 500 scientists and engineers in dual-earner families and with dependent care responsibilities. Findings  We find some support for the domain-specific predictors-to-outcomes model: FIW indirectly (but not directly) increases intentions to change organization through work dissatisfaction. Contrary to expectations from the stress management model we find neither direct nor indirect relationships between WIF and turnover intentions. Implications  Our findings suggest that organizations that help employees manage the effects of FIW on work dissatisfaction may be able to reduce the turnover among their technical workforce. Originality/value  The study examines an overlooked outcome of work-family conflict: turnover intentions. In addition, it provides much needed attention to the implications of workfamily conflict for scientists and engineers, who have received little attention in the work-family conflict literature despite longstanding efforts to understand the relationship between marriage, parenthood, and productivity in these fields.

Measurements of people’s causal and explanatory models are frequently key dependent variables in investigations of concepts and categories, lay theories, and health behaviors. A variety of challenges are inherent in the pen-and-paper and narrative methods commonly used to measure such causal models. We have attempted to alleviate these difficulties by developing a software tool, ConceptBuilder, for automating the process and ensuring accurate coding and quantification of the data. In this article, we present ConceptBuilder, a multiple-use tool for data gathering, data entry, and diagram display. We describe the program’s controls, report the results of a usability test of the program, and discuss some technical aspects of the program. We also describe ConceptAnalysis, a companion program for generating data matrices and analyses, and ConceptViewer, a program for viewing the data exactly as drawn.  相似文献

Quality of life is fast becoming a standard of measure of long-term care and gerontological service outcomes. Although the issue of quality of life has been of increasing interest in the field of aging, there has been little agreement as to the clarity and definition of the concept and how to measure it, especially as it relates to older adults. Presented here is a comprehensive, integrated model of quality of life that was developed by synthesizing existing constructs within the literature into six major life domains—(1) social well-being, (2) physical well-being, (3) psychological well-being, (4) cognitive well-being, (5) spiritual well-being, and (6) environmental well-being. Consistent with a general systems framework, this holistic model expands the predominant Health-Related Quality of Life constructs to incorporate non-physical aspects of well-being. Each of these domains was broken down into several dimensions in an effort to operationalize the concept of quality of life so that it can have some common standard of useful measurement. These major life domains and indicators are important factors in determining the perceptions of quality of life of older adults. Understanding what constitutes quality of life and how to measure it comprehensively has significant implications for social policy and practice in the field of aging.  相似文献

Studies show teachers play an influential role in the career decision-making process of students and early knowledge of genetic counseling (GC) increases the likelihood students will consider this career option. This quantitative study is the first to explore the presentation of GC and other health care career options by high school (HS) biology/life science (B/LS) teachers in their classrooms. Our findings indicate most B/LS teachers present GC as a career option to HS students, agree it complements classroom activities, and perceive students as interested in learning about the profession. However, teachers note many barriers to spending class time presenting GC careers. Consequently, a substantial number of teachers spent a minimal amount of time presenting health care careers in general. We discuss ways genetic counselors can enhance career resources, reduce barriers, and foster student interest in pursuing a career in GC by developing partnerships with HS B/LS teachers.  相似文献
