Humans regularly pursue activities characterized by dramatic success or failure outcomes where, critically, the chances of success depend on the time invested working toward it. How should people allocate time between such make‐or‐break challenges and safe alternatives, where rewards are more predictable (e.g., linear) functions of performance? We present a formal framework for studying time allocation between these two types of activities, and we explore optimal behavior in both one‐shot and dynamic versions of the problem. In the one‐shot version, we illustrate striking discontinuities in the optimal time allocation policy as we gradually change the parameters of the decision‐making problem. In the dynamic version, we formulate the optimal strategy—defined by a giving‐up threshold—which adaptively dictates when people should stop pursuing the make‐or‐break goal. We then show that this strategy is computationally inaccessible for humans, and we explore boundedly rational alternatives. We compare the performance of the optimal model against (a) a myopic giving‐up threshold that is easier to compute, and even simpler heuristic strategies that either (b) only decide whether or not to start pursuing the goal and never give up or (c) consider giving up at a fixed number of control points. Comparing strategies across environments, we investigate the cost and behavioral implications of sidestepping the computational burden of full rationality.  相似文献

We developed a two-study, cross-national, constructive replication to examine the role of organizational politics perceptions as a contextual moderator of the political skill – job performance relationship. Specifically, we hypothesized that high levels of political skill would demonstrate its strongest positive effects on job performance when politics perceptions were perceived as low. Conversely, we hypothesized that political skill would demonstrate no relationship with job performance under conditions of high politics perceptions. Across studies conducted both in the United States and Greece, the hypothesis received strong support. In settings characterized by lower perceived politics, high levels of political skill predicted significant increases in job performance, whereas these effects were attenuated in environments characterized by high perceived politics. Contributions and implications of this research, strengths and limitations, and directions for future study are discussed.  相似文献

This article critically reviews what is known about the ethical status of psychologists’ putative involvement with enhanced interrogations and torture (EITs). We examine three major normative ethical accounts (utilitarian, deontic, and virtue ethics) of EITs and conclude, contra the American Psychological Association, that reasonable arguments can be made that in certain cases the use of EITs is ethical and even, in certain circumstances, morally obligatory. We suggest that this moral question is complex as it has competing moral values involved, that is, the humane treatment of detainee competes with the ethical value/duty/virtue of protecting innocent third parties. We also suggest that there is an ethical duty to minimize harm by making only judicious and morally responsible allegations against the psychologists alleged to be involved in EITs. Finally, we make recommendations regarding completing the historical record, improvements in the professional ethics code, and the moral treatment of individuals accused in this controversy.  相似文献

Existing studies show that nurses often experience moral distress when the care they deliver to patients does not meet their professional values. We draw on ethnographic data collected in June 2015 from one acute care trust in England and present how frontline healthcare staff experience organizing complex hospital discharges. Our findings demonstrate how problems with the panel responsible for allocating funding for National Health Service continuing healthcare cases contributed to healthcare staff experiencing moral distress. Our findings offer a basis for further research on how other aspects of the complex hospital discharge-planning process may contribute to nurses’ experiencing moral distress.  相似文献

Using cross-sectional data from N = 4274 young adults across 16 countries during the COVID-19 pandemic, we examined the cross-cultural measurement invariance of the perceived vulnerability to disease (PVD) scale and tested the hypothesis that the association between PVD and fear of COVID-19 is stronger under high disease threat [that is, absence of COVID-19 vaccination, living in a country with lower Human Development Index (HDI) or higher COVID-19 mortality]. Results supported a bi-factor Exploratory Structural Equation Modeling model where items loaded on a global PVD factor, and on the sub-factors of Perceived Infectability and Germ Aversion. However, cross-national invariance could only be obtained on the configural level with a reduced version of the PVD scale (PVD-r), suggesting that the concept of PVD may vary across nations. Moreover, higher PVD-r was consistently associated with greater fear of COVID-19 across all levels of disease threat, but this association was especially pronounced among individuals with a COVID-19 vaccine, and in contexts where COVID-19 mortality was high. The present research brought clarity into the dimensionality of the PVD measure, discussed its suitability and limitations for cross-cultural research, and highlighted the pandemic-related conditions under which higher PVD is most likely to go along with psychologically maladaptive outcomes, such as fear of COVID-19.  相似文献

Arrigo, DeBatto, Rockwood, and Mawe (2015) take issue with a number of arguments in our previous article (O’Donohue et al., 2014). We respond in four major ways: (a) pointing out that they never really take on, let alone refute, the key argument in our article—that utilitarian, deontic, and virtue ethical theories are not only consistent with the use of enhanced interrogation and torture in the ticking time bomb scenario but these prescribe it; (b) there are numerous other exegetical problems in their article; (c) they make unsubstantiated claims about the ineffectiveness of EITSLs techniques that we argue are much too strong; and (d) they conflate the ethical with the legal and but even in doing so miss many important issues regarding the legality of EITSLs in the war on terrorism.  相似文献

Thirty-five healthy participants incidentally encoded a set of man-made and natural object pictures, while their pupil response and eye movements were recorded. At retrieval, studied and new stimuli were rated as novel, familiar (strong, moderate, or weak), or recollected. We found that both pupil response and fixation patterns at encoding predict later recognition memory strength. The extent of pupillary response accompanying incidental encoding was found to be predictive of subsequent memory. In addition, the number of fixations was also predictive of later recognition memory strength, suggesting that the accumulation of greater visual detail, even for single objects, is critical for the creation of a strong memory. Moreover, fixation patterns at encoding distinguished between recollection and familiarity at retrieval, with more dispersed fixations predicting familiarity and more clustered fixations predicting recollection. These data reveal close links between the autonomic control of pupil responses and eye movement patterns on the one hand and memory encoding on the other. Moreover, the data illustrate quantitative as well as qualitative differences in the incidental visual processing of stimuli, which are differentially predictive of the strength and the kind of memory experienced at recognition.  相似文献
