Building on previous research examining the implications for self-regulation and decision making of construing action at varying levels of abstraction, the authors proposed that construing action in terms of its abstract purposes facilitates orienting one’s decisions toward the standards, characteristics, and goals that define one’s desired self-concept. Consistent with this proposal, desiring for oneself a political candidate’s personal qualities predicted evaluating favorably (in Study 1) and voting for (in Study 2) that candidate to a greater extent among participants focused on the distal future (and presumably construing action at a relatively high-level of abstraction) than the proximal future (and presumably construing action at a relatively low-level of abstraction). Moreover, individuals chronically construing action in high-level terms responded more favorably to advertisements appealing to their desired self-concept (in Study 3) than to product quality. These findings’ implications for decision making are discussed. 相似文献

The purpose of this grounded theory study, based on Strauss and Corbin’s (1998) grounded theory methodology, was to investigate the meaning, definition, and needs regarding the role of spirituality in
end of life care among independent community dwelling older adults in relation to advance directive decision making (ADDM).
Findings revealed that through the use of story telling, independent community dwelling older adults were able to define spirituality
and describe the important role spirituality plays in everyday life and in ADDM. A theoretical model was constructed consisting
of a mirrored basic social process, Spirituality as Connecting. 相似文献

This paper tests a behavioral property called dimension integration. The test evaluates models, such as lexicographic semi-orders and the priority heuristic, which assume that a person uses only one dimension at a time. It provides a way to compare such models against those that assume a person combines information from different dimensions. The test allows one to test the hypothesis that different people use different lexicographic semi-orders with different threshold parameters. In addition, by use of a “true and error” model, it is possible to “correct” for unreliability of choice in order to estimate the proportions of participants who show different response patterns that can be classified as integrative or not integrative. An experiment with 260 participants was conducted in which people made choices between two-branch gambles. The aggregate results violate the priority heuristic and six lexicographic semi-orders. The data also refute the theory that people use a mixture of these lexicographic semi-orders. In addition, few individuals appear to show response patterns consistent with non-integrative models. Instead, they show that most individuals show patterns consistent with the hypothesis that they combine information between dimensions. 相似文献

Development of a Tissue Engineered Heart Valve for Pediatrics: A Case Study in Bioengineering Ethics
Merryman WD 《Science and engineering ethics》2008,14(1):93-101
The following hypothetical case study was developed for bioengineering students and is concerned with choosing between two
devices used for development of a pediatric tissue engineered heart valve (TEHV). This case is intended to elicit assessment
of the devices, possible future outcomes, and ramifications of the decision making. It is framed in light of two predominant
ethical theories: utilitarianism and rights of persons. After the case was presented to bioengineering graduate students,
they voted on which device should be released. The results revealed that these bioengineering students preferred the more
reliable (and substantially more expensive) design, though this choice precludes the majority of the world from having access
to this technology. This case is intended to examine and explore where the balance lies between design, cost, and adequate
distribution of biomedical devices. 相似文献

According to classical decision theory, an agent realises at time t the option with maximum expected utility (determined by his beliefs and desires at t), where the relevant options are possible actions performed at t. I consider an alternative according to which the relevant options are in general plans, complex courses of action extending into the future. 相似文献

This paper presents people accounting—a hypothesis that describes how a simple numerical imbalance in representation along nominal social category lines can affect people’s choice of candidates in highly competitive situations (e.g., awards, jobs, etc.). For example, two scholarship finalists from California and New York may be equally qualified, but the award-winning chance for the California candidate will drop precipitously if 8 of the past 10 winners were from California. Studies 1-3 illustrate this effect. Study 4 links people accounting to intergroup fairness concerns and suggests that people accounting is more likely to occur when the category dimension is meaningful (e.g., Stanford/Princeton) than when it is not (e.g., left/right-handedness). Study 5 shows that candidates from overrepresented categories (e.g., “Californians”) must achieve higher minimum standards in order to be selected. The implication is that highly competitive decisions are often influenced by headcounts along mundane social category lines. 相似文献

Regulatory Focus Theory was applied to small interactive groups. Based on previous research, it was expected that groups with a promotion focus would discuss gain-relevant information, whereas groups with a prevention focus would be concerned with potential losses. Furthermore, promotion groups were expected to make riskier decisions than prevention groups. Regulatory focus was manipulated by rewarding good or penalizing poor group performance on a preliminary task. Subsequently, three-person groups discussed several investment funds and made a consensual investment decision. Results supported the hypotheses and suggested that regulatory focus requires time to exert its influence in groups. 相似文献

Substantial evidence indicates that information is distorted during decision making, but very few studies have assessed the distortion of probability and outcome information in risky decisions. In two studies involving six binary decisions (e.g., banning blood donations from people who have visited England, because of “mad cow disease”), student and nonstudent participants distorted their evaluations of probability and outcome information in the direction of their preferred decision alternative and used these biased evaluations to update their preferences. Participants also evaluated the utilities of possible outcomes more positively when the outcomes could follow only from the preferred alternative and more negatively when they could follow only from the competing alternative. Such circular reasoning is antithetical to the normative consequentialist principles underlying decision analysis. Presenting numerical information as precise values or as ranges of values did not significantly affect information distortion, apparently because the manipulation did not affect perceived ambiguity as intended. 相似文献
