The right interpretation of subjective probability is implicit in the theories of upper and lower odds, and upper and lower previsions, developed, respectively, by Cedric Smith (1961) and Peter Walley (1991). On this interpretation you are free to assign contingent events the probability 1 (and thus to employ conditionalization as a method of probability revision) without becoming vulnerable to a weak Dutch book.

ABSTRACT— In a series of studies, we examined novel predictions drawn from a conceptualization of probability as psychological distance. Manipulating construal level in a number of different ways and examining a variety of probability judgments, we found that participants led to adopt a high-level-construal mind-set made lower probability assessments than did those led to adopt a low-level-construal mind-set. Moreover, this occurred even when construal level was manipulated in a context separate from the judgment task and the manipulation was unrelated in content to the events being judged. These findings suggest that broad processing variables can exert a widespread influence on probability judgment.  相似文献

ABSTRACT This article investigates the effects that perceived challenges and skills in activities have on the quality of everyday life experience. Based on flow theory it was predicted that quality of daily experience would depend on the challenge experienced and skill required in specific situations, as well as on the balance between challenge and skill. The Experience Sampling Method (ESM) was used on a sample of 208 talented adolescents to measure daily variations in four dimensions of experience (concentration, wish to do the activity, involvement, and happiness) in four contexts (in school, with relatives, with friends, and in solitude). The four dimensions of experience were regressed on the predictors challenges, skills, and their absolute difference expressing the balance/imbalance of challenges and skills. Hierarchical linear modeling, explained in detail herein, was conducted on a 1-week sample of experiences. Findings confirm the prediction of flow theory that the balance of challenges and skills has a positive and independent effect on the quality of experience. Yet some differences of parameter estimates were found between dimensions of experience and between social contexts. These heterogeneities call for a further improvement of the flow model.  相似文献

Results of previous calibration studies are used to identify features of the decision maker and the decision environment which might be expected to result in good calibration. Racetrack bettors and, in particular, the UK parimutuel betting market are identified as possessing such characteristics. In order to explore calibration in this setting, an analysis is undertaken of bets placed on 19,396 horses. A close correlation is observed between the subjective probability judgments of horses' success, implicit in the bettors' wagering activities, and the objective probability of success of the horses concerned. Explanations for the results are offered in terms of characteristics of racetrack bettors and the naturalistic setting, with particular reference to the operation of the betting market. The results contribute to an emergent school of thought which advocates naturalistic enquiry as a complement to laboratory-based experiments in further developing the understanding of decision making.  相似文献

采用三因素完全随机实验探究主观概率判断是否满足次可加性规律,结果表明:(1)分解方式、分解数量和分解事例的典型性等三个因素对主观概率判断均有显著的影响。(2)次可加性不是一种普遍现象,主观概率判断中也会出现可加性和超可加性:把事件隐分为非典型事例时会出现超可加性,把事件隐分为典型或者典型加非典型性的事例时会出现可加性,而把事件显分时会一致出现次可加性。  相似文献

This study investigated the relationship between threat appraisal, distressful reactions, and coping strategies of Israeli civilians under missile attack during the Gulf War. During the war, 66 subjects were asked about their perceived probability of being hurt by the missiles. Additionally, they completed a questionnaire that measured their fears and symptoms during the war, the State Anxiety scale of the Endler Multidimensional Anxiety Scales, and the Coping Inventory for Stressful Situations (CISS, Endler & Parker, 1990). The results showed an inverted U-shaped relationship between perceived probability of being hurt and the anxiety measures. A similar curvilinear relationship was found between perceived probability of being hurt and emotion coping strategy. Furthermore, it was found that those who appraised the possibility of being hurt as very high, more often used avoidance coping. The results are discussed within the framework of stress theories and are related to other inverted U-shape relationships found between threat appraisal and stressful reactions.  相似文献

This paper develops a classical model for our ordinary use of the truth predicate (1) that is able to address the liar's paradox and (2) that satisfies a very strong version of deflationism. Since the model is a classical in the sense that it has no truth value gaps, the model is able to address Tarski's indictment of our ordinary use of the predicate as inconsistent. Moreover, since it is able to address the liar's paradox, it responds to arguments against deflationism based upon that paradox alone. The model is based upon a notion of the complexity of propositions that a fixed set of speakers might express. A context-sensitive definition of the truth predicate is then provided based upon a class of possible worlds defined in terms of these speakers. Reasonable constraints on the memories and lifetimes of ordinary speakers are used to limit the set of propositions that they might express so that deflationist requirements are satisfied.  相似文献

An increasing number of older workers are attempting career changes; however, little is known about the antecedents or outcomes of these changes. Results indicate that perceived objective and perceived subjective career‐change success are predicted by different combinations of variables. Implications for both future research and practice are discussed.  相似文献

The current literature shows cross-cultural differences related to implicit theories of ageing. Specifically, in the Western individualistic cultural context, elderly people are perceived as obsolete, weak and unable to contribute usefully to society, whereas in collectivistic cultures, older people are venerated as a source of knowledge and cultural traditions (e.g. Yoon et al. in Psychol Aging 15:694–704, 2000). The focus of the current study was to investigate the effect of age-related factors affecting self-referent well-being in the Italian population. One hundred and thirty-nine healthy adults (20–99 years) were recruited in Northern Italian (i.e. individualistic context) and Sardinian (i.e. collectivist context) contexts and were, respectively, assigned to the following groups: Young (20–30 years old), Old (65–74 years old) and Very Old (>75 years old). Participants were administered a battery of tests, including self-referent cognitive efficiency scales, subjective psychological well-being, depression and psychological distress scales. Participants from Sardinia showed greater levels of well-being and lower levels of psychological distress than adults from Northern Italy. Moreover, participants from the Old group reported more coping strategies, emotional competencies and personal satisfaction, as well as fewer depressive symptoms, than the Very Old group. One possible explanation is that sociocultural contexts emphasising the positive social role of the elderly like that prevailing in Sardinia promote psychological well-being in late adulthood.  相似文献

This paper aims to untangle the relationship between income and subjective well-being. To accomplish this, we investigate how subjective well-being is affected by two financially-related determinants that have not been investigated before or scarcely so. Specifically, we research the impact on subjective well-being of how people are coping with their present income as well as of their borrowing constraints. The results indicate that both variables determine subjective well-being and that they mediate the effects of other variables, namely income, which is not directly related to well-being. Additionally, they signal that income matters to the extent to which it contributes to meeting the desired consumption needs and eases borrowing constraints. Such mediating effects thus contribute to explain how income affects subjective well-being. We also inspect differences in life satisfaction responsiveness to perceived income adequacy and borrowing constraints in certain groups of individuals, and find that the subjective well-being of individuals in a more fragile financial position is particularly responsive to the alleviation of borrowing constraints.  相似文献

In a recent article, Schreij, Owens, and Theeuwes (2008) reported that abruptly onsetting distractors produce costs in performance even when spatial-cuing effects confirm the presence of a top-down set for color. The authors argued that these results show that abruptly onsetting new objects capture attention independent of a top-down set and, thus, provide conclusive evidence against the theory that attentional capture is contingent on top-down attentional control settings (Folk, Remington, & Johnston, 1992). In the following article, we argue that, contrary to the conclusion drawn by Schreij et al., their own data (1) disconfirm the claim that their abrupt onsets captured spatial attention and (2) are consistent with nonspatial interference accounts of singleton-distractor effects. In support of the nonspatial account, we show that in a paradigm similar to Schreij et al.’s, distractors that do not capture attention can nonetheless influence responses to a target. We conclude that the results of Schreij et al. do not represent a challenge to contingent capture theory.  相似文献

Based on the acknowledgment of what I have designated as cracks in our theoretical models, I have advanced some hypotheses that account for the constitution of social, familial, and individual subjectivity. I have attributed great significance to the concept of the unforeseeable. The unforeseeable is tied to uncertainty, which is related in turn to the flow of interpersonal relations. I have also discussed new forms of suffering that stem from conditions imposed by the social context, in this case, the expulsion from one's territory. I chose this phenomenon because of the importance I attach both to the feeling of social belonging and to subjects' need to create stable places in a world in constant flux. Some clinical vignettes illustrated these reflections.  相似文献

基于毕生控制理论,方便选取杭州市60~95岁的老年人320名,采用问卷法考察了老年人控制策略使用的现状和特点,并在控制了年龄、健康状况、日常活动数量后,探讨了老年人的乐观、领悟社会支持与主观幸福感的关系,以及控制策略的中介作用。结果发现:低龄的老年男性和女性更偏好选择初级和补偿初级策略,而高龄老年女性更偏好补偿初级策略;乐观和领悟社会支持不仅可以直接影响老年人的主观幸福感,还可以通过选择初级策略间接影响主观幸福感。初级控制在老年人中依然具有首要性地位,老年人的资源越丰富,越有可能采用积极的控制策略(选择初级),进而提高主观幸福感,实现成功老龄化。  相似文献

In his theory of trauma, Ferenczi points to the disbelief of adults of a child's account of an event as an actual traumatizing factor. Ferenczi also states that of all the consequences of the trauma, which include identification with the aggressor, psychic coma, departure from the possibility of dreams, and a fall to the hell of nightmares, the most important and fundamental is the lack of certainty of self. The disbelief of the adults destroys the certainty of what is perceived and experienced; it has the power of annihilating the child's belief in his own perceptions, his trust in his own senses. The loss of certainty of self appears to be a common characteristic in patients with distinct psychic dynamics. We will analyze the loss of certainty of self in cases of patients of the NEPECC (Núcleo de Estudos em Psicanálise e Clínica da Contemporaneidade) [Center of Studies in Psychoanalysis and Contemporarity Clinic] at the Federal University of Rio de Janeiro.  相似文献
