Two scenario studies investigated the impact of the investment of instrumental and noninstrumental effort on the intensity of disappointment and regret. The role of effort was investigated in the context of other determinants of disappointment and regret: the desirability of the outcome, its likelihood, and the perceived responsibility for (not) obtaining the outcome. Study 1 shows that after failure, disappointment is more intense after an investment of higher levels of instrumental effort, whereas regret is more intense an investment of less instrumental effort. Study 2 shows that both disappointment and regret are more intense after an investment of higher levels of noninstrumental effort. Further analyses suggest that the effect of instrumental effort on disappointment is due to a direct effect of the investment of effort. The effect of instrumental effort on disappointment was mediated by the perceived likelihood of attaining the outcome and also related to the perceived desirability of the outcome. The impact of instrumental effort on regret was found to be due to a direct effect of the investment of effort, and to the perceived responsibility for not attaining the outcome. The effect of the investment of noninstrumental effort on the intensity of both disappointment and regret was found to be due to a direct effect of effort. Desirability also affected disappointment (with increased desirability leading to higher levels of disappointment), whereas only regret was affected by perceived responsibility. Implications of these findings for the study of disappointment and regret are discussed.  相似文献

In classical and contemporary social theory alike, the key to understanding how cultural change comes about has been thought to lie in the long-term effect of differential cohort socialization. Cultural change is thought to proceed as differently socialized cohorts replace each other in the course of time. Moreover, distinct generations have been claimed to emerge. Thisarticle addresses the impact of cohort replacement and the presence of generations, including discussions of the theoretical framework underlying these concepts and the problem of disentangling age, period, and cohort effects. Analyses of Dutch survey data substantiate that cohort membership matters. Yet the impact of cohort replacement on cultural change turns out to be limited, and little evidence is found in support of the idea that specific generations arediscernible.  相似文献

Increasing participation of Muslims and Hindus in church-state relations in the Netherlands is bringing about a slow change in the different cultural and historical backgrounds of non-indigenous religious traditions and in their self-esteem and religious attitudes. We may call this participation, and especially the changes it causes, a good example of Systemzwang, the systematic power of the dominant but historically grown social and cultural order in which newcomers are expected to fit. This process of external influence will be demonstrated by the example of the development of the traditional Hindu priest, the pandit, to a modern professional pastoral or Hindu-spiritual counsellor and by the mutual-learning process of the religiously different pastoral professionals in the semi-governmental service organizations.  相似文献

Although the feminist critique of marriage and family therapy has been a significant part of the literature for many years, its impact has been blunted by two criticisms. The first suggests that the feminist critique lacks empirical support. The second suggests that the feminist critique promotes an alliance with women clients at the expense of men. The first criticism has been addressed in recent years. The present study examined the relationship between feminist principles and therapeutic alliance. Results suggest that feminist principles actually enhance therapeutic relationship for men clients but has no effect on therapeutic relationship for women clients.of the Marriage and Family Therapy Program  相似文献

The aim of this study was to determine whether word stem completion for novel associations between cue and target words was mediated by automatic unconscious memory processes or effortful memory processes under conscious control. This was done by applying full and divided attention conditions at test to stem completion, cued recall, and recognition, and by administering a questionnaire that probed the memory strategies used by subjects during the completion test. Divided attention had no effect on stem completion performance, but did reduce associative cued recall. Recognition performance was weakened overall by divided attention, but the associative effect was similar under both attention conditions. This suggested that novel associative word stem completion was mediated by automatic retrieval processes. However, the results of the questionnaire indicated that only subjects who attempted to remember the words from the study phase during the completion task showed any novel associative effect. It is concluded that novel association word stem completion and cued recall share automatic retrieval processes, which nevertheless give rise to the experience of remembering.  相似文献

Conduct Disorder in Girls: A Review of the Literature   总被引:8,自引:0,他引:8  
The study of Conduct Disorder (CD) has primarily been limited to boys. The lack of research resulted from a premise that CD in girls was rare. However, CD in girls is a relatively common psychiatric diagnosis, and appears to be associated with several serious outcomes, such as Antisocial Personality Disorder and early pregnancy. Understanding gender differences in the course and severity of CD may lead to important information about etiology. Empirical studies on precursors, developmental course, risk factors and treatment for CD in girls are reviewed, while highlighting similarities and differences between girls and boys. Generally, CD symptoms in girls are stable. Precursors to CD in girls probably include Oppositional Defiant Disorder and temperamental factors, but also may include certain negative cognitions. What distinguishes CD in girls is the high risk they have to develop comorbid conditions, especially internalizing disorders. Risk factors for CD in girls partly overlap with those known for boys, but some factors appear to be highly salient for girls. Finally, there may be some significant effects of gender on treatment efficacy. Implications of these findings for future etiologic research are discussed.  相似文献

Conclusion It is clear that the concept of scientific misconduct continues to evolve. As always it is the goal of Science and Engineering Ethics to move the discussion forward, to encourage and facilitate discussion of the ethical issues and problems that practicing scientists and engineers encounter in the course of pursuing their professions. This collection of articles and commentaries provides a variety of perspectives that we expect will facilitate communication among and within the groups who must participate in this evolution. The opinions expressed herein are those of the author and do not necessarily reflect the policies of the Office of Research Integrity, the Department of Health and Human Services, or any other Federal agency.  相似文献

This commentary distinguishes between the engineering-inspired formalisms used by Brackstone, M., and McDonald, M. (Transportation Research Part F (1999)) and the psychological knowledge of, and assumptions about human behaviour when car following. It outlines a preliminary mathematical model, based on psychological knowledge about car following behaviour by human drivers, which could be applied in traffic engineering, as a means of bringing these two ways of studying car following closer together.  相似文献

In his classic paper, The Principle of Alternate Possibilities, Harry Frankfurt presented counterexamples to the principle named in his title: A person is morally responsible for what he has done only if he could have done otherwise. He went on to argue that the falsity of the Principle of Alternate Possibilities (PAP) implied that the debate between the compatibilists and the incompatibilists (as regards determinism and the ability to do otherwise) did not have the significance that both parties had attributed to it -- since moral responsibility could exist even if no one was able to do otherwise. I have argued that even if PAP is false, there are other principles that imply that moral responsibility entails the ability to do otherwise, and that these principles are immune to Frankfurt-style counterexamples. Frankfurt has attempted to show that my arguments for this conclusion fail. This paper is a rejoinder to that reply; I argue that he has failed to show this.  相似文献
