This study investigates how the contribution, identification, and consideration of expertise within groups are affected by gender differences. The authors examined the effects of member expertise and gender on others' perceptions of expertise, actual and own perceptions of influence, and group performance on a decision-making task. The authors' findings are consistent with social role theory and expectation states theory. Women were less influential when they possessed expertise, and having expertise decreased how expert others perceived them to be. Conversely, having expertise was relatively positive for men. These differences were reflected in group performance, as groups with a female expert underperformed groups with a male expert. Thus, contrary to common expectations, possessing expertise did not ameliorate the gender effects often seen in workgroups. The findings are discussed in light of their implications for organizational workgroups in which contribution of expertise is critical to group performance.  相似文献

The measurement of posttraumatic stress disorder (PTSD) is critically important for the identification and treatment of this disorder. The PTSD Checklist (PCL; F. W. Weathers and J. Ford, 1996) is a self-report measure that is increasingly used. In this study, the authors investigated the factorial validity of the PCL with data from 236 cancer survivors who received a bone marrow or stem cell transplantation. The authors examined the fit of these data with the clinical model of 3 symptom clusters for PTSD, as proposed in the Diagnostic and Statistical Manual of Mental Disorders, and alternative models tested in prior research. By using confirmatory factor analysis the authors found that a 4-first-order-factor model of PTSD provided the best fit. The relations of PTSD symptoms with sociodemographic and medical variables were also explored.  相似文献

The present research tested the extent to which perceptions of early childhood experiences with parents predicted general views of the self (i.e., self‐esteem) and others (i.e., humanity‐esteem), and whether attachment self‐ and other‐models mediated these links. Two studies used a new measure of humanity‐esteem (Luke & Maio, 2004) to achieve these ends. As expected, indices that tapped a positive model of the self in relationships were associated with high self‐esteem and indices that tapped a positive model of others in relationships were associated with high humanity‐esteem. Also, early attachment experiences with fathers and mothers predicted self‐esteem and humanity‐esteem, respectively, and these direct relations were mediated by the attachment models. The studies, therefore, provide direct evidence that attachment measures predict general favorability toward the self and others, while revealing novel differences in the roles of childhood experiences with fathers and mothers.

A prevalent assumption in text comprehension research is that many aspects of text processing are automatic, with automaticity typically defined in terms of properties (e.g., speed and effort). The present research advocates conceptualization of automaticity in terms of underlying mechanisms and evaluates two such accounts, a computational-efficiency account (underlying computational processes become more efficient with practice) and a memory-based processing account (the underlying basis of processing shifts with practice, from computing interpretations to retrieving prior interpretations). In five experiments, short texts containing either an ambiguous or unambiguous syntactic structure were presented for multiple study trials. In both conditions, reading times in target regions decreased across trials, indicating automatization. Several findings supported the memory-based processing account (e.g., practice effects were largely item-specific, reading times were longer for ambiguous versus unambiguous sentences on early trials but converged on later trials) Some evidence was also found for a contribution of gains in computational efficiency (i.e., some item-general practice effects were observed). Implications for research on automaticity and text processing are discussed.  相似文献

This article presents and discusses four clinical cases that exemplify the complexity of ethical dilemmas concerning the provider's obligation to disclose or withhold genetic information from patients. Case 1: What is the responsibility of the cancer genetics provider to ensure that a positive test results is shared with distant relatives? Case 2: To ensure that results go to at-risk relatives, do we have the right to ignore the wishes of the designated next-of-kin? Case 3: Do we have the right to reveal a familial BRCA1 mutation to a patient's relative, who is at 50% risk? Case 4: Do we have an obligation to reveal that a patient is not a blood relative and therefore, not at risk to have inherited a familial mutation? These cases form the basis for discussing the provider's dual obligations to keeping patient confidentiality and informing patients and families about risk (i.e. duty to warn). We also provide a summary of consensus points and additional discussion questions for each case.  相似文献

Previous research investigating the influence of perceived physical attractiveness on student evaluations of college professors has been limited to a handful of studies. In this study, the authors used naturally occurring data obtained from the publicly available Web site www.ratemyprofessors.com. The data suggested that professors perceived as attractive received higher student evaluations when compared with those of a nonattractive control group (matched for department and gender). Results were consistent across 4 separate universities. Professors perceived as attractive received student evaluations about 0.8 of a point higher on a 5-point scale. Exploratory analyses indicated benefits of perceived attractiveness for both male and female professors. Although this study has all the limitations of naturalistic research, it adds a study with ecological validity to the limited literature.  相似文献

A large body of literature has supported the application of attachment theory to the understanding of psychotherapy. In addition, a more recent social psychological literature is exploring the application of attachment theory to the area of group dynamics and group process. The current study is designed to integrate these two distinct bodies of literature. In a preliminary fashion, we examined the relationship between group therapists' group attachment styles and their assumptions and expectations of their patients' attitudes about group psychotherapy. Seventy-six therapists completed the Smith, Murphy & Coats (1999) measure of group attachment style. They also completed the Revised Group Therapy Survey (Carter, Mitchell, & Krautheim, 2001) from the viewpoint of a typical patient they treat. As hypothesized, therapists with more group attachment anxiety assumed that patients would hold more negative myths and misconceptions about group treatment than therapists with less group attachment anxiety. The utility of a group attachment construct in future research and practice is discussed.  相似文献

Empirical support exists for parent training/education (PT/PE) interventions for children with disruptive behavior disorders (DBD) and autism spectrum disorders (ASD). While the models share common roots, current approaches have largely developed independently and the research findings have been disseminated in two different literature traditions: mental health and developmental disabilities. Given that these populations often have overlapping clinical needs and are likely to receive services in similar settings, efforts to integrate the knowledge gained in the disparate literature may be beneficial. This article provides a systematic overview of the current (1995–2005) empirical research on PT/PE for children with DBD and ASD; attending to factors for cross-fertilization. Twenty-two ASD and 38 DBD studies were coded for review. Literature was compared in three main areas: (1) research methodology, (2) focus of PT/PE intervention, and (3) PT/PE procedures. There was no overlap in publication outlets between the studies for the two populations. Results indicate that there are opportunities for cross-fertilization in the areas of (1) research methodology, (2) intervention targets, and (3) format of parenting interventions. The practical implications of integrating these two highly related areas of research are identified and discussed.  相似文献

There are over 800 seventh to tenth grade students at the College d’Enseignment Generale (CEG) School in Azové, Benin. Like most children in the developing world, these students lack access to clean water and basic sanitation facilities. These students suffer from parasitic infection and health ailments which could be directly offset with short term aid to supply water and medical aid. Promoting proper sanitation and providing the technology to implement water and wastewater treatment in the community will decrease childhood and maternal disease and mortality rates in Azové. However, these measures may take several years to implement and will require a significant investment in the infrastructure of the school. Is it ethical to spend $10,000 towards the long-term goals of providing water and sanitation to the students of CEG Azové, compared to spending the same amount on short-term relief efforts? This paper addresses the ethical dilemma of dealing with immediate medical needs in developing countries while trying to implement sustainable technologies. The views and frustration of students working on the project are discussed, as they realize the monetary and short-term impacts on human health when implementing sustainable technologies. The opportunity costs associated with the education principles of sustainable development were also considered. The anticipated costs and health impacts in the short-term and long-term will be evaluated for a period of 1, 2, 5 and 10 years.  相似文献

The present study used two cognitive tasks--a text comprehension task and a homophone task--to investigate whether clinically depressed individuals have a negative bias when interpreting ambiguous information. Previous research indicates that both tasks are sensitive to anxiety-related interpretive biases, and that the former is less prone to response bias effects. Negative memory biases were also assessed. Results showed that, compared with normal controls, depressed individuals made more negative interpretations on the homophone task, and they also showed an enhanced negative recall bias. However, the groups did not differ in interpretative bias on the text comprehension task. Possible explanations of the results are discussed, including the potential influences of self-referent processing and response bias.  相似文献
