Four experiments explored whether lacking power impairs executive functioning, testing the hypothesis that the cognitive presses of powerlessness increase vulnerability to performance decrements during complex executive tasks. In the first three experiments, low power impaired performance on executive-function tasks: The powerless were less effective than the powerful at updating (Experiment 1), inhibiting (Experiment 2), and planning (Experiment 3). Existing research suggests that the powerless have difficulty distinguishing between what is goal relevant and what is goal irrelevant in the environment. A fourth experiment established that the executive-function impairment associated with low power is driven by goal neglect. The current research implies that the cognitive alterations arising from powerlessness may help foster stable social hierarchies and that empowering employees may reduce costly organizational errors.  相似文献

Levenson, Kiehl, and Fitzpatrick's Self-Report Psychopathy Scale (LSRPS) is evaluated to determine the factor structure and concurrent validity of the instrument among 430 federal female inmates. Confirmatory factor analysis fails to validate the expected 2-factor structure. Subsequent exploratory factor analysis reveals a 3-factor structure (egocentric, antisocial, and callous), where each factor accounts for significant variance in scores on several theoretically relevant measures. Higher scores on the antisocial factor of the LSRPS are associated with a history of varied psychopathological and negative legal outcomes, suggesting evidence of concurrent validity. However, the egocentric and callous factors do not seem to measure precisely the same construct as the primary psychopathy factor from the Levenson et al. study. The 3-factor structure proposed here has been proposed by other researchers and found in other samples of psychopathy in female inmates. Implications for both research and clinical practice using the LSRPS with female inmates are discussed.  相似文献

The effective risk management of sexual offenders is arguably one of the most contentious social issues of our day. The community is justifiably outraged by what it perceives to be a failure of correctional and mental health practitioners to demonstrate that rehabilitative and supervisory methods promote public safety. Those who treat offenders and attempt to manage risk are often frustrated by what appear, at times, to be emotion-based reactions to low base-rate incidents. The literature on effective correctional programming has produced a workable model—Risk/Needs/Responsivity (RNR)—in which interventions match intensity of treatment to level of risk, specifically target criminogenic needs, and tailor treatment to the personal and interpersonal needs and capacities of participants. However, this model has been criticized regarding an apparent failure to appreciate the totality of client needs, specifically with respect to offender responsivity concerns. The Good Lives Model (GLM) suggests that treatment for sexual offenders must regard participants as whole beings in need of focus in many principal life areas (e.g., family, employment, leisure, community, personal well-being). This article proposes that RNR and GLM are complementary and that, by emphasizing the merits of each, offender management and general well-being can be maximized while community safety is increased.  相似文献

OBJECTIVE: To compare the impact of network support and different types of perceived functional support on all-cause mortality or nonfatal reinfarction for patients with a recent acute myocardial infarction (AMI). DESIGN: Participants were recruited from the Enhancing Recovery in Coronary Heart Disease (ENRICHD) trial; 2,481 AMI patients with depression or low social support were randomized to a cognitive-behavioral intervention or to a usual care control group. Data collection for certain measures of social support was limited: 2,466 participants completed the ENRICHD Social Support Inventory; 2,457 completed the Perceived Social Support Scale; 1,296 completed the Social Network Questionnaire; and 707 completed the Interpersonal Support and Evaluation List, Tangible Support subscale. Patients also completed the Beck Depression Inventory and were followed for up to 4.5 years. MAIN OUTCOME MEASURE: Time to death or nonfatal reinfarction. RESULTS: Over the follow-up period, 599 patients (24%) died or had a nonfatal AMI. Survival models controlling age, sex, race, socioeconomic status, smoking, antidepressant use, and a composite measure of increased risk revealed that higher levels of perceived social support were associated with improved outcome for patients without elevated depression but not for patients with high levels of depression. Neither perceived tangible support nor network support were associated with more frequent adverse events. CONCLUSION: AMI patients should be assessed for multiple dimensions of perceived functional support and depression to identify those at increased psychosocial risk who may benefit from treatment.  相似文献

This study examined the effects of felt accountability, political skill, and job tension on job performance ratings. Specifically, we hypothesized that felt accountability would lead to higher (lower) job performance ratings when coupled with high (low) levels of political skill, and that these relationships would be mediated by job tension. Data were gathered at multiple times over a one-year period (i.e., baseline performance, attitudinal variables one month later, supervisor reports of subordinate performance six months and one year after baseline performance was measured). Strong support was shown for the total effects model, whereby political skill moderated felt accountability—job performance ratings, felt accountability—job tension, and job tension—job performance ratings relationships. However, more focused analyses demonstrated that political skill most strongly moderated the job tension—job performance ratings linkage. Implications, strengths and limitations, and directions for future research are provided.  相似文献

When Are Tutorial Dialogues More Effective Than Reading?   总被引:2,自引:0,他引:2  
It is often assumed that engaging in a one-on-one dialogue with a tutor is more effective than listening to a lecture or reading a text. Although earlier experiments have not always supported this hypothesis, this may be due in part to allowing the tutors to cover different content than the noninteractive instruction. In 7 experiments, we tested the interaction hypothesis under the constraint that (a) all students covered the same content during instruction, (b) the task domain was qualitative physics, (c) the instruction was in natural language as opposed to mathematical or other formal languages, and (d) the instruction conformed with a widely observed pattern in human tutoring: Graesser, Person, and Magliano's 5-step frame. In the experiments, we compared 2 kinds of human tutoring (spoken and computer mediated) with 2 kinds of natural-language-based computer tutoring (Why2-Atlas and Why2-AutoTutor) and 3 control conditions that involved studying texts. The results depended on whether the students' preparation matched the content of the instruction. When novices (students who had not taken college physics) studied content that was written for intermediates (students who had taken college physics), then tutorial dialogue was reliably more beneficial than less interactive instruction, with large effect sizes. When novices studied material written for novices or intermediates studied material written for intermediates, then tutorial dialogue was not reliably more effective than the text-based control conditions.  相似文献

The authors investigated the effects of mock juror age (younger vs. older), defendant age (22 vs. 65), and type of excuse defense used by defendants (a highly self-inflicted condition, Cocaine Dependency Disorder, vs. a less self-inflicted condition, Posttraumatic Stress Disorder) on mock juror decisions. Ninety-six younger and 96 older adults read a scenario and answered a questionnaire. Results indicated that the defendant using the highly self-inflicted excuse was more likely to receive a guilty verdict and a longer sentence than was the defendant using the less self-inflicted excuse. Older jurors were more certain of their verdicts and saw the defendant as more responsible for his condition than did younger jurors. Defendant age did not affect juror decisions. In addition, excuse type and juror age affected the jurors' perceptions of the victim's responsibility for the attack. The authors discuss the potential influence of juror age on perceptions of defendant responsibility.  相似文献

The Facing Our Risk of Cancer Empowered (FORCE) website is devoted to women at risk for hereditary breast and ovarian cancers. One of the most frequently discussed topics on the archived messaged board has been prophylactic mastectomy (PM) for women with a BRCA1/2 mutation. We reviewed the messages, over a 4 year period, of 21 high risk women and their “conversational” partners who originally posted on a thread about genetic testing, genetic counseling and family history. We used a qualitative research inductive process involving close reading, coding and identification of recurrent patterns, relationships and processes in the data. The women sought emotional support, specific experiential knowledge and information from each other. They frequently found revealing their post PM status problematic because of possible negative reactions and adopted self-protective strategies of evasion and concealment outside of their web-based community. The FORCE message board was considered to be a safe place in which the women could be truthful about their choices and feelings. Results are discussed in terms of Goffman’s concepts “stigma” and “disclosure” and Charmaz’s concepts “interruptions,” “intrusions” and a “dreaded future.”  相似文献

This study examines contradictions in the “American Dream” during the Great Recession: young adults maintained high educational aspirations, yet perceived little opportunity for their educational achievements to help them fulfil their dreams of financial prosperity and work stability. Based on in‐depth interviews with 85 young college students and recent graduates, this study found that college enrolment was propelled by the recession, as a college degree, and often a graduate or professional degree, was perceived as an increasingly necessary credential. Despite these high educational aspirations, students and recent graduates were fearful about their capacity to find future work and they expressed concerns about the collapse of employment opportunity. Many were also wary of educational institutions, which they viewed as unable to prepare them for a shrinking job market. These perceptions reveal a contradiction in the “American Dream:” although young adults have high aspirations and achievements, they have lost confidence in the educational and work institutions upon which they must depend.  相似文献
