Conlon and Garland (1993) demonstrated that information about the degree of project completion, as compared with information about sunk costs, seemed to be the driving force behind continued investment in an R&D project. In the present paper, we replicate and extend this work. In studies with experienced bank managers, Chinese graduate students, and advanced-level MBA students, we find overwhelming support for the importance of project completion on investment intentions, with no indication of typical sunk cost effects. We argue that our results support a goal substitution explanation for many escalation phenomena where, as progress moves forward on a project, completion of the project itself takes increasing precedence over other goals (e. g., economic profit) that may have been more salient at the time the project was initiated. 相似文献

The purpose of this study is to determine whether leisure behavior, leisure satisfaction, leisure attitude, and self-determination are associated with decreased burnout. A systematic stratified random sample of 438 clergy (55% return rate) was used to collect the data. In path analysis, results indicate that leisure behavior and leisure satisfaction had an inverse effect on all 3 components of burnout, while leisure attitude had no effect. Self-determination predisposition contributed inversely to 2 components of burnout. Similarly, age and years in ministry had a direct, inverse relationship with the emotional exhaustion and depersonalization dimensions of burnout. Number of years employed with the present church was also negatively related to emotional exhaustion. All 3 variables (age, years in ministry, and years with the present church) were positively associated with leisure behavior. Theoretical and practical implications of these findings are discussed. 相似文献

To what extent do differences in biologicalsexand psychological gender identity influence affectivereactions to different genres of film? In order toaddress this question, this investigation examined the impact of sex and gender roleself-perceptions on viewers' responses to neutral,melodramatic, and violent film segments. Working with apredominantly Caucasian population (93% Caucasian) at asoutheastern university, the results emphasize theimportance of sex and gender role self-perceptions onviewers' affective responses to media entertainment. Theimplications of these findings are discussed.

EXPANDING THE MOTHER-CHILD PARADIGM 总被引:1,自引:0,他引:1
Reliance on the mother–child dyad as the primary context for under–standing child development has caused fathers to be underrepresented in published research on child development and developmental psychopathology. In order to investigate whether this pattern was also evident in the work of future psychologists, we reviewed Dissertation Abstracts from 1986 through 1994. Results showed that fathers were the focus of significantly fewer dissertation studies (10.5%) than were mothers (59.5%) or both parents (30.0%). We argue that essentializing the mother–child bond is a political philosophy about the roles of men and women that places the discipline of psychology at risk for inadvertently becoming an apologist for the neoconservative political right. Specific suggestions for revising graduate training are presented. The social policy implications for continuing this trend into the next generation of psychologists are discussed. 相似文献

To investigate how gender, ethnicity, age and education influence aggressiveness, we surveyed 115 male and female college students (56% male; 50% Anglo and 26% Hispanic) and 79 persons (72% male; 92% Anglo) working on a military base. Participants were administered the Buss-Perry Aggression Questionnaire and asked about their own aggressive behaviors. In both samples, men scored significantly higher than women on the Physical Aggression scale of the Aggression Questionnaire but not on the other scales. In the military sample, men indicated that they expected to behave more aggressively than women. Positive correlations among different aspects of aggressiveness were found for both men and women. Increasing age and education were associated with lower aggressiveness in both genders, suggesting that aggressiveness may be susceptible to modification over the course of one's life.We would like to thank Angela Bennett, Gail Bliss, Kayleigh Carabajal, Julie Depree, Carmen Gonzales, Deborah Good, Scott Griffin, Gladys Herrera, George Selix, Ruth Tangman, and Jon Woodland for their assistance with the development, distribution, and coding of the questionnaire. 相似文献

A number of well-described, controlled studies assessing cancer support group intervention support their effectiveness. All of these experimental groups have been close-ended and typically involve six to eight weekly sessions. Because many cancer patients are unable or unwilling to participate in closed, extended-session groups, there is particular need for analysis of the effectiveness of short-term, open-ended groups. Additionally, objective measures are needed to delineate the factors contributing to a successful outcome in cancer support groups. We used the Short Form of the Group Climate Questionnaire (GCQ-S) to characterize 23 sessions in an open-ended, short-term, Veterans Hospital based cancer support group. The cancer group scored significantly lower on the Avoiding and Conflict dimensions (p<.001) compared to a normative psychotherapy group sample. There was no difference on the Engaged dimension. This pilot study suggests that a cancer support group in this setting can create an environment where members are cohesive and take responsibility for their own change process, while keeping interpersonal conflict to a minimum. Based on these preliminary findings, we encourage controlled clinical trials examining the efficacy of open-ended cancer support groups.At the time of this study, Dr. Daroff was a resident in Psychiatry, University of California, San Francisco. 相似文献

In studies related to human movement, linked segment models (LSM's) are often used to quantify forces and torques, generated in body joints. Some LSM's represent only a few body segments. Others, for instance used in studies on the control of whole body movements, include all body segments. As a consequence of the complexity of 3-dimensional (3-D) analyses, most LSM's are restricted to one plane of motion. However, in asymmetric movements this may result in a loss of relevant information. The aim of the current study was to develop and validate a 3-D LSM including all body segments. Braces with markers, attached to all body segments, were used to record the body movements. The validation of the model was accomplished by comparing the measured with the estimated ground reaction force and by comparing the torques at the lumbo-sacral joint that resulted from a bottom-up and a top-down mechanical analysis. For both comparisons, reasonable to good agreement was found. Sources of error that could not be analysed this way, were subjected to an additional sensitivity analysis. It was concluded that the internal validity of the current model is quite satisfactory. 相似文献

In a series of three experiments, subjects made risky decisions under conditions of hypothetical or real consequences. Task variations across experiments included: (1) type of risk (monetary gambles or investments of time and effort), (2) within-subject and between-subjects manipulations of consequence condition, and (3) single or multiple decisions. The hypothesis of no difference between choices in real and hypothetical consequence conditions was retained in each experiment. Supplemental analyses ruled out various “artifactual” interpretations of the null results. Discussion focused on conditions in which researchers can and cannot infer decision makers’ actual risk preferences from their responses in laboratory tasks. 相似文献
