A series of four experiments investigated preschoolers’ abilities to make sense of dominance relations. Experiments 1 and 2 showed that as early as 3 years old, preschoolers are able to infer dominance not only from physical supremacy but also from decision power, age, and resources. Experiments 3 and 4 showed that preschoolers have expectations regarding the ways in which a dominant and a subordinate individual are likely to differ. In particular, they expect that an individual who imposes his choice on another will exhibit higher competence in games and will have more resources.  相似文献

Physicians make some medical decisions without disclosure to their patients. Nondisclosure is possible because these are silent decisions to refrain from screening, diagnostic or therapeutic interventions. Nondisclosure is ethically permissible when the usual presumption that the patient should be involved in decisions is defeated by considerations of clinical utility or patient emotional and physical well-being. Some silent decisions—not all—are ethically justified by this standard. Justified silent decisions are typically dependent on the physician's professional judgment, experience and knowledge, and are not likely to be changed by patient preferences. We condemn the inappropriate exclusion of the patient from the decision-making process. However, if a test or treatment is unlikely to yield a net benefit, disclosure and discussion are at times unnecessary. Appropriate silent decisions are ethically justified by such considerations as patient benefit or economy of time.  相似文献

Optimal Bayesian reasoning performance has reportedly been elusive, and a variety of explanations have been suggested for this situation. In a series of experiments, it is demonstrated that these difficulties with replication can be accounted for by differences in participant-sampling methodologies. Specifically, the best performances are obtained with students from top-tier, national universities who were paid for their participation. Performance drops significantly as these conditions are altered regarding inducements (e.g., using unpaid participants) or participant source (e.g., using participants from a second-tier, regional university). Honours-programme undergraduates do better than regular undergraduates within the same university, paid participation creates superior performance, and top-tier university students do better than students from lower ranked universities. Pictorial representations (supplementing problem text) usually have a slight facilitative effect across these participant manipulations. These results indicate that studies should take account of these methodological details and focus more on relative levels of performance rather than absolute performance.  相似文献

Lewis' Strawman     
In a survey of his views in the philosophy of mind, David Lewis criticizes much recent work in the field by attacking an imaginary opponent, 'Strawman'. His case against Strawman focuses on four central theses which Lewis takes to be widely accepted among contemporary philosophers of mind. The theses concern (1) the language of thought hypothesis and its relation to folk-psychology, (2) narrow content, (3) de se content, and (4) rationality. We respond to Lewis, arguing (amongst other things) that he underestimates Strawman's theoretical resources in a variety of important ways.  相似文献

We examined the benefits to a corporate sponsor of two types of philanthropic activities — cause promotions and advocacy advertising. Results from 4 laboratory studies indicate that perceptions of corporate social responsibility (CSR) are affected by consumers’ elaboration levels. Consumer perceptions of CSR are more favorable for cause promotions, which do not receive much elaboration, than they are for advocacy advertising, which prompts more elaboration. In addition, perceived congruence between the sponsor and the social issue is shown to moderate these effects: Higher congruence between the sponsor and social issue increases favorable ratings of CSR for cause promotions but only if elaboration on the sponsorship activity is facilitated. On the other hand, lower congruence increases favorable ratings of CSR for advocacy advertising as long as elaboration on the sponsorship is not constrained. We also found that higher congruence enhances CSR ratings if participants are primed to focus their attention on the sponsor brand, whereas lower congruence enhances CSR if participants are primed to focus their attention on the social issue.  相似文献

This article identifies ‘the tragedy of the commons’ as an essentially aggregative harm and considers what agents in such a scenario owe to one another. It proposes that the duty to take reasonable precautions requires that agents make efforts to establish collective solutions to any essentially aggregative harm to which they would otherwise contribute. Baylor Johnson has argued that the general obligation to promote the common good requires that agents make efforts to establish a collective agreement to avert a potential tragedy of the commons. This article agrees with Johnson's analysis but argues that there are also negative duties, which give commons users additional moral reason to take collective action to prevent the destruction of the utility of the commons. These duties link commons users to resolving this particular problem and provide grounds to demand that they make greater efforts to prevent the destruction of the commons compared to bystanders. The article suggests that fulfilling negative duties can require establishing collective institutions with the power to regulate human action and interaction. This analysis could be applied to a range of social problems which result from the aggregation of actions and practices.  相似文献
