In their 2015 article, Osgood and Muraven showed that cognitive depletion reduces prosocial behaviors but not prosocial attitudes. We expand on the authors’ interpretation by relating their results to recent theorizing on the relationship between prosocial behavior and self-control. This framework distinguishes between the proclivity to identify self-control conflict and the capacity to exercise restraint. Osgood and Muraven's findings can be interpreted as evidence that cognitive depletion in social contexts fails to influence a necessary condition for identifying self-control conflict. However, the results do not yet allow us to conclude that depletion influences capacity to exercise restraint. Further work is needed to understand the mechanisms by which cognitive depletion influences prosocial behavior. 相似文献

Multiple contraction (simultaneous contraction by several sentences) and iterated contraction are investigated in the framework
of specified meet contraction (s.m.c.) that is extended for this purpose. Multiple contraction is axiomatized, and so is finitely
multiple contraction (contraction by a finite set of sentences). Two ways to reduce finitely multiple contraction to contraction
by single sentences are introduced. The reduced operations are axiomatically characterized and their properties are investigated.
Furthermore, it is shown how iterated contraction can be reduced to single-step, single-sentence contraction. However, in
this framework the outcome of iterated contraction depends unavoidably on the order in which the inputs are received. This
order-dependence makes it impossible to treat two inputs on an equal footing. Therefore it is often preferable to perform
changes involving several pieces of information as multiple rather than iterated change. 相似文献

It is almost universally acknowledged that risks have to be weighed against benefits, but there are different ways to perform the weighing. In conventional risk analysis, collectivist risk-weighing is the standard. This means that an option is accepted if the sum of all individual benefits outweighs the sum of all individual risks. In practices originating in clinical medicine, such as ethical appraisals of clinical trials, individualist risk-weighing is the standard. This implies a much stricter criterion for risk acceptance, namely that the risk to which each individual is exposed should be outweighed by benefits for that same individual. The different choices of risk-weighing methods in different policy areas seem to have emerged from traditional thought patterns and social relations, rather than from explicit deliberations on possible justifications for the alternative ways to weigh risks against benefits. It is not obvious how the prevalent differences in risk-weighing practices can be reconstructed in terms of consistent underlying principles of preventive health or social priority-setting. 相似文献

A general theory of coherence is proposed, in which systemic and relational coherence are shown to be interdefinable. When
this theory is applied to sets of sentences, it turns out that logical closure obscures the distinctions that are needed for
a meaningful analysis of coherence. It is concluded that references to “all beliefs” in coherentist phrases such as “all beliefs
support each other” have to be modified so that merely derived beliefs are excluded. Therefore, in order to avoid absurd conclusions,
coherentists have to accept a weak version of epistemic priority, that sorts out merely derived beliefs. Furthermore, it is
shown that in belief revision theory, coherence cannot be adequately represented by logical closure, but has to be represented
separately.

All living adults with histopatologically proven diagnosis of low-grade glioma in a Swedish county were identified with help of the Regional Cancer Register, half of them (n = 24) participated in a neuropsychological evaluation. A considerable variation was found in cognitive function within this group of patients, ranging from good ability to severe disturbance. Different patterns of cognitive dysfunction emerged resulting in three subgroups; patients with severe, mild, and minimal selective dysfunction. The patients with severe disturbance had a global dysfunction covering most assessed cognitive domains. Slow information-processing speed was obvious in the subgroups with both severe and mild dysfunction. Cognitive problems present in the best performing group seemed related to tumor localization. Cognitive function in the whole sample was related to histopathological diagnosis of the tumor, as well as to educational level of the patients. The nonworking patients had significantly poorer performance than the working patients. 相似文献

The British Stroke Driver Screening Assessment (SDSA) is a set of four simple cognitive tests to evaluate driving fitness in stroke patients. To evaluate its usefulness in a Scandinavian context, we adapted the tests and assessed a group of 97 stroke patients from Sweden and Norway, using a driving test as the criterion. When results were calculated according to the original method, based on a discriminant function, less than 70% of the participants were correctly classified. To improve the predictive potential, a new discriminant analysis was performed, using the scores of a subsample of 49 patients, and validated on the remaining 48 participants. In total, 78% of the patients were correctly classified, but specificity was superior to sensitivity. We conclude that the Nordic version of the SDSA is a useful instrument, provided that test scores are interpreted in a balanced manner, taking into account the possibility of compensatory traffic behavior. 相似文献

This study was designed to assess the expressed emotion (EE) status in the spouses of depressed patients and the patients themselves, to relate the EE status to the severity of depression as measured by the Beck Depression Inventory (BDI), and to compare the prevalence of high EE between the target and control group. Seventeen depressed patients and their spouses, and 20 control couples participated in the study. The Five-Minute Speech Sample was used to assess the EE status. High EE was significantly more common in spouses of depressed patients and the patients themselves than in controls. There was a significant relationship between the EE status of the patients and their spouses. High EE in the patient and in the spouse corresponded significantly with a high BDI score of the patient. These findings underline the importance that in EE research the patients' EE status as well as their present mental health state must also be taken into account. 相似文献

A possible world semantics for preference is developed. The remainder operator () is used to give precision to the notion that two states of the world are as similar as possible, given a specified difference between them. A general structure is introduced for preference relations between states of affairs, and three types of such preference relations are defined. It is argued that one of them, actual preference, corresponds closely to the concept of preference in informal discourse. Its logical properties are studied and shown to be plausible. 相似文献

An experiment, in the standard scientific sense of the term, is a procedure in which some object of study is subjected to interventions (manipulations) that aim at obtaining a predictable outcome or at least predictable aspects of the outcome. The distinction between an experiment and a non-experimental observation is important since they are tailored to different epistemic needs. Experimentation has its origin in pre-scientific technological experiments that were undertaken in order to find the best technological means to achieve chosen ends. Important parts of the methodological arsenal of modern experimental science can be traced back to this pre-scientific, technological tradition. It is claimed that experimentation involves a unique combination of acting and observing, a combination whose unique epistemological properties have not yet been fully clarified. 相似文献
