Prior research has shown that positive information presented by a third party shields people from the negative consequences of being perceived as self-promoting. But in many contexts, those third parties are intermediaries with a financial interest in the person being promoted rather than neutral parties. In three experimental studies, the authors demonstrate that even when intermediaries are not neutral, they can be helpful for overcoming the self-promotion dilemma--the need to assert one's competence but not be harmed by the fact that people who self-promote are viewed negatively. The authors find that hiring an agent to sing one's praises results in more favorable perceptions of the client, which contributes, in turn, to a greater willingness to offer that person assistance. It is also shown that even when the intermediary is physically present and seen to be complicit with the client, the positive effects of having someone else speak on one's behalf persist.  相似文献

Cross-cultural studies on personality in which a combined etic-emic approach has been used have found a 6th personality factor--Interpersonal Relatedness--in addition to the usual Big Five. The authors examined age differences in Interpersonal Relatedness among Canadians and Hong Kong Chinese after statistically controlling for the Big Five. Age differences in some aspects of Interpersonal Relatedness were found among Hong Kong Chinese but not among Canadians, suggesting that development of some personality characteristics may differ across cultures.  相似文献

Empirical studies of personality traits in creative writers have demonstrated mixed findings, perhaps due to issues of sampling, measurement, and the reporting of statistical information. The goal of this study is to quantify the personality structure of aspiring creative writers according to a modern hierarchal model of trait personality. A sample of aspiring writers (n = 93) and nonwriters (n = 114) completed the Big Five inventory. Correlations with personality were carried out at three levels: the Big Five traits, the two higher-order factors (stability and plasticity), and the more detailed facet-level. Consistent with past research, creative writers scored higher on trait openness. Extending past work, the hierarchical analysis also revealed novel correlates for the higher-order meta-traits (stability and plasticity) and some of the lower-order facets (aesthetics, ideas, activity, assertiveness, and depression). Individuals with higher scores on agreeableness, stability, and assertiveness were less likely to be aspiring writers. The likelihood of being a writer also decreased with age. Taken together, these findings indicate that aspiring creative writers differ from nonwriters in trait personality, with differences emerging at all levels of the personality hierarchy.  相似文献

There are two competing theoretical perspectives on how job tenure might affect job performance. Human capital theory suggests that as knowledge and skill increase with greater tenure, job performance will improve as well. In contrast, the literature on job design suggests that as job tenure increases, employees are likely to become more bored and less motivated at work. Consequently, the gains from human capital acquisition might be offset by losses of motivation. To examine these competing perspectives, we conducted meta-analyses on the relationships of job tenure with four types of job performance: core task performance, citizenship behavior, creativity and innovative behavior, and counterproductive work behavior. The results support the second perspective, as both the linear and curvilinear relationships of job tenure with the four types of job performance are weak. Further, the results do not change in strength across type of research design, job industry, age, or gender.  相似文献

Automated reasoning about uncertain knowledge has many applications. One difficulty when developing such systems is the lack of a completely satisfactory integration of logic and probability. We address this problem directly. Expressive languages like higher-order logic are ideally suited for representing and reasoning about structured knowledge. Uncertain knowledge can be modeled by using graded probabilities rather than binary truth values. The main technical problem studied in this paper is the following: Given a set of sentences, each having some probability of being true, what probability should be ascribed to other (query) sentences? A natural wish-list, among others, is that the probability distribution (i) is consistent with the knowledge base, (ii) allows for a consistent inference procedure and in particular (iii) reduces to deductive logic in the limit of probabilities being 0 and 1, (iv) allows (Bayesian) inductive reasoning and (v) learning in the limit and in particular (vi) allows confirmation of universally quantified hypotheses/sentences. We translate this wish-list into technical requirements for a prior probability and show that probabilities satisfying all our criteria exist. We also give explicit constructions and several general characterizations of probabilities that satisfy some or all of the criteria and various (counter)examples. We also derive necessary and sufficient conditions for extending beliefs about finitely many sentences to suitable probabilities over all sentences, and in particular least dogmatic or least biased ones. We conclude with a brief outlook on how the developed theory might be used and approximated in autonomous reasoning agents. Our theory is a step towards a globally consistent and empirically satisfactory unification of probability and logic.  相似文献

Older adults commonly experience declines in prospective memory, which describes one’s ability to “remember to remember,” and can adversely affect instrumental activities of daily living and healthcare compliance. However, the extent to which prospective memory failures may influence quality of life in typically aging older adults is not well understood. One-hundred and four community-dwelling older Australians (aged 50 to 82 years) were administered a comprehensive, neuropsychological battery that included the Memory for Intentions Screening Test (MIST), Prospective and Retrospective Memory Questionnaire (PRMQ), Instrumental Activities of Daily Living Questionnaire (IADLQ), and World Health Organization Quality of Life-8 (WHOQOL-8). Multiple regressions controlling for negative affect, medical comorbidities, and other neurocognitive functions revealed an interaction between prospective memory and instrumental activities of daily living in the concurrent prediction of quality of life. Among the 39 older adults who reported multiple problems on the IADLQ, lower performance-based prospective memory (MIST) and higher self-reported prospective memory failures in daily life (PRMQ) were significantly associated with lower quality of life (WHOQOL-8). Conversely, no significant associations were observed between prospective memory and quality of life in the 65 participants without IADL problems. Prospective memory difficulties adversely impact quality of life in community-dwelling older adults who experience problems independently managing their instrumental activities of daily living. These findings extend prior literature showing that prospective memory plays a unique role in the real-world outcomes of older adults and clinical populations and highlight the need to develop effective strategies to enhance prospective memory functioning in these vulnerable groups.  相似文献

This study of 230 predominantly poor Hispanic and African American women aged 25 to 61 years living with HIV/AIDS in New York City revealed high levels of both sexual (39%) and physical (44%) trauma before the age of 16. Both types of early trauma were correlated with later trauma, and all forms of trauma were significantly associated with current perceived health. In multivariate analyses controlling for relevant covariates, the Powerful Others and Internal Control subscales of the Multidimensional Health Locus of Control Scales (K. A. Wallston, B. S. Wallston, & R. DeVellis, 1978) acted as independent predictors of perceived health rather than (as hypothesized) mediators of the association between trauma and perceived health. Findings underscore the importance of addressing trauma and perceptions of control over one's physical health in the provision of health services to HIV-positive women.  相似文献

Data from 7 studies were aggregated to examine how reported sexual arousal and alcohol intoxication interact to affect attitudes and intentions toward engaging in unprotected sexual intercourse in college-age men (N = 358). When participants were in a sober or placebo condition, their self-reports of sexual arousal had no effect on their responses. When participants were intoxicated, however, those who felt sexually aroused reported more favorable attitudes, thoughts, and intentions toward having unprotected sex than did those who did not feel aroused. These findings support alcohol myopia theory (C. M. Steele & R. A. Josephs, 1990), which states that alcohol intoxication restricts attentional capacity so that people are highly influenced by the most salient cues in their environment. It is suggested that sexual arousal is a powerful internal cue that interacts with alcohol intoxication to enhance attitudes and intentions toward risky sexual behaviors.  相似文献

Rare or low probability targets are detected more slowly and/ or less accurately than higher probability counterparts. Various proposals have implicated perceptual and response-based processes in this deficit. Recent evidence, however, suggests that it is attentional in nature, with low probability targets requiring more attentional resources than high probability ones to detect. This difference in attentional requirements, in turn, suggests the possibility that low and high probability targets may have different susceptibilities to attention capture, which is also known to be resource-dependent. Supporting this hypothesis, we found that, once attentional resources have begun to be engaged by detection processes, low, but not high, probability targets have a reduced susceptibility to capture. Our findings speak to several issues. First, they indicate that the likelihood of attention capture occurring when a given task-relevant stimulus is being processed is dependent, to some extent, on how said stimulus is represented within mental task sets. Second, they provide added support for the idea that the behavioural deficit associated with low probability targets is attention-based. Finally, the current data point to reduced top-down biasing of target templates as a likely mechanism underlying the attentional locus of the deficit in question.  相似文献
