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.

Hot or not: do professors perceived as physically attractive receive higher student evaluations? 总被引:1,自引:0,他引:1
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

Most studies of widowhood have focused on reactions during the first few years postloss. The authors investigated whether widowhood had more enduring effects using a nationally representative U.S. sample. Participants were 768 individuals who had lost their spouse (from a few months to 64 years) prior to data collection. Results indicated that the widowed continued to talk, think, and feel emotions about their lost spouse decades later. Twenty years postloss, the widowed thought about their spouse once every week or 2 and had a conversation about their spouse once a month on average. About 12.6 years postloss, the widowed reported feeling upset between sometimes and rarely when they thought about their spouse. These findings add to an understanding of the time course of grief. 相似文献

We used the Rasch (1980) model to develop new pictures for the Thematic Apperception Test (C. D. Morgan & Murray, 1938; McClelland, Atkinson, Clark, & Lowell, 1953) or picture story exercise to measure need for achievement (nAch). In Experiments 1 and 2, we analyzed stories to assess the difficulty level of a total of 8 pictures using the multifaceted Rasch model with picture difficulty, story probe difficulty, and participant ability as facets with a partial credit model (FACETS; Linacre, 2005). A total of 6 pictures were retained and 4 new ones added for Experiment 3 in which 201 participants wrote 6 stories to a random set of the 10 pictures. FACETS analysis revealed improved person separation reliability. In Experiment 4, 206 participants wrote 1 story to the Studying picture either before or after filling out a battery of achievement-related questionnaires. The 2 experimental groups did not differ in the amount of nAch in their stories. The coder facet was demonstrated with 2 independent coders using the revised coding system for nAch. 相似文献

12 nondemented patients with Parkinson's disease (M age = 67.3) and 12 normal control participants were administered an object-based attention task that enabled examination of both negative and positive priming. Unlike previous studies in which spatial-based attention tasks were used, results of the present study indicated that the patients displayed negative and positive priming not different from those shown by controls. These results suggest that certain object-based attentional processes may not be impaired in patients with Parkinson's disease. 相似文献

This study assessed whether a practice effect occurs across five serial administrations of the sensory organization test. Composite equilibrium scores and mean equilibrium scores from 30 healthy volunteers (M age=36.9, SD = 12.2 yr.) performing each of the six test conditions were examined using a two-way repeated-measures analysis of variance. Analysis yielded a significant interaction between testing condition and time, as well as significant main effects for both condition and time. Pairwise comparisons showed significant differences among test conditions and the first and second times of test administration. Analysis of simple effects between the two administrations identified significant increases in composite equilibrium scores and mean equilibrium scores on two sway-referenced support surface conditions, vision removed and sway-referenced visual surround. An immediate increase in equilibrium scores suggests clinicians and researchers allow one pracatice trial before recording test scores for baseline measurements. 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

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
