Moral relativism is an attractive position, but also one that it is difficult to formulate. In this paper, we propose an alternative
way of formulating moral relativism that locates the relativity of morality in the property that makes moral claims true.
Such an approach, we believe, has significant advantages over other possible ways of formulating moral relativism. We conclude
by considering a few problems such a position might face. 相似文献

The effect of hippocampal denervation on olfactory memory in rats was tested after interrupting the lateral olfactory tract projections at the level of the entorhinal cortex. When lesioned animals were trained to learn new odors, they showed no evidence of retention 3 h after acquisition. These results confirm earlier data on rapid forgetting in rats after hippocampal deafferentation and are in parallel to the anterograde amnesia typically found in humans with hippocampal damage. On the other hand, preoperatively learned information was minimally impaired after hippocampal deafferentation even if it was acquired within less than 1 h before the lesion. This finding differs from reports on humans as well as monkeys with hippocampal damage where memories formed during a critical time span of months or even years before the lesion are found to be impaired. This may suggest that the consolidation process in humans and rodents has different time scales or that the roles of the human and the rat hippocampal structure in memory formation are somewhat different. 相似文献

The literature purporting to demonstrate that clinical neuropsychology is of limited validity in the forensic setting is reviewed critically and alternative interpretations are discussed. The methodological, procedural, conceptual, data analytical and survey/research design limitations are evaluated.Portions of this paper were presented at the 1992 annual meeting of the National Academy of Neuropsychology, Pittsburgh, Pennsylvania. 相似文献

This paper describes sudden extreme drops in blood pressure in both experimental and clinical situations when a person is talking about or describing situations of hopelessness and helplessness. These changes are discussed in the context of historical perspectives about the cardiovascular system. A new perspective is introduced, one in which these blood pressure changes are seen as part of an unheard cry for understanding. It is hypothesized that such changes do not occur in response to a person's attempts to communicate a sense of hopelessness, but rather are the biological foundations of the hopelessness itself. Viewed from such a context an entirely new therapeutic approach is outlined regarding the treatment of patients suffering from a wide variety of psychosomatic as well as psychological disturbances. 相似文献

Musical tuning perception in infancy and adulthood was explored in three experiments. In Experiment 1, Western adults were tested in detection of randomly located mistunings in a melody based on musical interval patterns from native and nonnative musical scales. Subjects performed better in a Western major scale context than in either a Western augmented or a Javanese pelog scale context. Because the major scale is used frequently in Western music and, therefore, is more perceptually familiar than either the augmented scale or the pelog scale are, the adults' pattern of performance is suggestive of musical acculturation. Experiments 2 and 3 were designed to explore the onset of culturally specific perceptual reorganization for music in the age period that has been found to be important in linguistically specific perceptual reorganization for speech. In Experiment 2, 1-year-olds had a pattern of performance similar to that of the adults, but 6-month-olds could not detect mistunings reliably better than chance. In Experiment 3, another group of 6-month-olds was tested, and a larger degree of mistuning was used so that floor effects might be avoided. These 6-month-olds performed better in the major and augmented scale contexts than in the pelog context, without a reliable performance difference between the major and augmented contexts. Comparison of the results obtained with 6-month-olds and 1-year-olds suggests that culturally specific perceptual reorganization for musical tuning begins to affect perception between these ages, but the 6-month-olds' pattern of results considered alone is not as clear. The 6-month-olds' better performance on the major and augmented interval patterns than on the pelog interval pattern is potentially attributable to either the 6-month-olds' lesser perceptual acculturation than that of the 1-year-olds or perhaps to an innate predisposition for processing of music based on a single fundamental interval, in this case the semitone. 相似文献
