Leadership, collective personality, and performance   总被引:1,自引:0,他引:1  
By viewing behavior regularities at the individual and collective level as functionally isomorphic, a referent-shift compositional model for the Big 5 personality dimensions is developed. On the basis of this compositional model, a common measure of Big 5 personality at the individual level is applied to the collective as a whole. Within this framework, it is also hypothesized that leadership (i.e., transformational, transactional, and passive) would predict collective personality and that collective personality would be significantly related to collective performance. The results supported these hypotheses using a sample of franchised units. On the basis of recent research at the individual level, several interactions among the various personality dimensions were hypothesized and supported. Implications are discussed.  相似文献

Despite the strong positive feelings that characterize newlyweds, many marriages end in disappointment. To understand this shift, the authors argue that although newlyweds' global relationship evaluations may be uniformly positive, not all spouses base their global adoration on an accurate perception of their partner's specific qualities. Two longitudinal studies confirmed that whereas most newlyweds enhanced their partners at the level of their global perceptions, spouses varied significantly in their perceptions of their partners' specific qualities. For wives, but not for husbands, more accurate specific perceptions were associated with their supportive behaviors, feelings of control in the marriage, and whether or not the marriage ended in divorce. Thus, love grounded in specific accuracy appears to be stronger than love absent accuracy.  相似文献

Five studies manipulated the memory perspective (1st-person vs. 3rd-person) individuals used to visually recall autobiographical events and examined its effects on assessments of personal change. Psychotherapy clients recalled their first treatment (Study 1), and undergraduates recalled past social awkwardness (Study 2). Participants who were induced to recall from the 3rd-person perspective believed, and acted as though (Study 2), they had changed more since the events occurred. Subsequent studies revealed a crucial moderator: Third-person recall produces judgments of greater self-change when people are inclined to look for evidence of change, but lesser self-change when they are inclined to look for evidence of continuity. This pattern emerged when motivation (Studies 1 and 2), goals (Study 3), instructions (Study 4), and self-esteem (Study 5) determined participants' focus on change versus continuity. Results have implications for constructivism in memory and judgment and for the ability to sustain self-improvement efforts.  相似文献

The authors investigated how individual factors (age, gender, gender role, past experiences of sexual harassment) and organizational factors (gender ratio, sexual harassment policies, the role of employers) related to workers' attitudes toward and perceptions of sexual harassment. In Study 1, participants were 176 workers from a large, white-collar organization. In Study 2, participants were 75 workers from a smaller, blue-collar organization. Individuals from Study 2 experienced more sexual harassment, were more tolerant of sexual harassment, and perceived less behavior as sexual harassment than did individuals from Study 1. For both samples, organizational and individual factors predicted workers' attitudes toward and experiences of sexual harassment. Individual factors-such as age, gender, gender role, past experiences of sexual harassment, and perceptions of management's tolerance of sexual harassment-predicted attitudes toward sexual harassment. Workers' attitudes, the behavioral context, and the gender of the victim and perpetrator predicted perceptions of sexual harassment. The authors discussed the broader implications of these findings and suggested recommendations for future research.  相似文献

The objective of this document is to provide recommendations for genetic evaluation and counseling of couples with recurrent miscarriage (RM). The recommendations are the opinions of the multidisciplinary Inherited Pregnancy Loss Working Group (IPLWG), with expertise in genetic counseling, medical genetics, maternal fetal medicine, internal medicine, infectious disease, cytogenetics, and coagulation disorders. The IPLWG defines RM as three or more clinically recognized consecutive or non-consecutive pregnancy losses occurring prior to fetal viability (<24 weeks gestation). These recommendations are provided to assist genetic counselors and other health care providers in clinical decision-making, as well as to promote consistency of patient care, guide the allocation of medical resources, and increase awareness of the psychosocial and cultural issues experienced by couples with RM. The IPLWG was convened with support from the March of Dimes Western Washington State Chapter and the University of Washington Division of Medical Genetics. The recommendations are U.S. Preventive Task Force Class III, and are based on clinical experiences, review of pertinent English-language published articles, and reports of expert committees. This document reviews the suspected causes of RM, provides indications for genetic evaluation and testing, addresses psychosocial and cultural considerations, and provides professional and patient resources. These recommendations should not be construed as dictating an exclusive course of medical management, nor does the use of such recommendations guarantee a particular outcome. The professional judgment of a health care provider, familiar with the circumstances of a specific case, should always supersede these recommendations.  相似文献

Fragile X syndrome (FXS) is primarily due to a repeat expansion mutation found in the FMR1 X-linked gene. We have conducted a qualitative analysis of responses from women concerning their attitudes toward testing for carrier status of the fragile X mutation among reproductive-age women. We obtained responses from focus groups including women with and without FXS in their families. We found the following themes: (1) mothers of children with FXS have difficulty formulating their opinions on population screening because of their unique experiences surrounding their own carrier diagnosis and their relationship with their children with FXS, (2) the motivation for carrier testing and need for information differ by family history of FXS and parental status, and (3) the timing of carrier testing with respect to a woman’s life stage dictates whether carrier information will be viewed as beneficial or detrimental. There was evidence that non-carrier women from the general population would be wholly unprepared for positive carrier results. These findings have significant implications for genetic counseling as well as for population screening.  相似文献

Patients anticipating surgical procedures experience significant anxiety, resulting in adverse outcomes and increased expenditures. Research has investigated the impact of anxiety-reducing interventions, frequently the provision of surgical information, with inconsistent results. The present study (N = 98) examined preference for information, or monitor-blunter coping style, and the impact of a pre-surgical phone call from an anesthesiologist on anxiety in which treatment group participants (n = 51) dictated the amount of information received. Monitors were hypothesized to desire more information than blunters, and changes in anxiety for monitors/blunters were hypothesized to be moderated by length of call. Monitors and blunters demonstrated equal call durations and anxiety levels remained equivalent across groups. Findings and implications for future research are discussed.  相似文献

Routine animal husbandry variables, such as group housing of mice and the order of testing of cagemates, are currently viewed to be essentially neutral with respect to the outcome of most, if not all, animal-based experiments, including those that utilize behavioral measurements. During the course of experiments that have utilized the elevated plus-maze to examine the ability of a bacterial challenge of mice to induce anxiety-like behavior, due to the activation of various cytokine pathways, we followed the recommendation of laboratory animal care staff to house the mice in pairs. When we tested the members of the pairs successively, it was found, for the first experimental set, that the behavior that reflects anxiety (time in closed arms) of the first-tested animal differed from that of the second-tested animal for both the experimental and the control animals and, critically, that these changes were in the opposite directions for the controls and the experimental animals, thus obscuring the effect of the experimental manipulation. A second, independent experimental set also obtained a significant effect for the order of testing effect in the bacterial-challenged group, but not in the saline control group, although a similar trend was evident in this group as well. These results indicate that special care should to be taken in implementing housing recommendations and that preliminary tests may be necessary to ensure that housing conditions do not interact with tests of the phenomenon under experimental investigation.  相似文献

Poverty is among the most challenging social problems in the United States today, and beliefs about the government's role in reducing inequality and raising living standards for the poor are critical to alleviating poverty and its consequences. Du Bois recognized the complex challenges associated with poverty and was ahead of his time in pointing to ethnicity and religion as fundamental to creating change and alleviating poverty. Du Bois’ ideas continue to be relevant today, including for understanding ethnic differences among Catholics in attitudes toward poverty, which are likely changing given the growth of the Latino population. In the spirit of Du Bois’ seminal research, I compare Latino and non-Latino Catholic attitudes toward poverty and inequality using the 2021 General Social Survey. Findings document critical differences among Catholics in beliefs about poverty and inequality and highlight the interdependent role of religion, ethnicity, and demographics (e.g., age, gender, socioeconomic status [SES]) in shaping attitudes.  相似文献
