Picture and word triads were tested in a Brown-Peterson short-term retention task at varying delay intervals (3, 10, or 30 sec) and under acoustic and simultaneous acoustic and visual distraction. Pictures were superior to words at all delay intervals under single acoustic distraction. Dual distraction consistently reduced picture retention while simultaneously facilitating word retention. The results were interpreted in terms of the dual coding hypothesis with modality-specific interference effects in the visual and acoustic processing systems. The differential effects of dual distraction were related to the introduction of visual interference and differential levels of functional acoustic interference across dual and single distraction tasks. The latter was supported by a constant 2/1 ratio in the backward counting rates of the acoustic vs. dual distraction tasks. The results further suggest that retention may not depend on total processing load of the distraction task, per se, but rather that processing load operates within modalities. 相似文献

The article offers an approach to inquiry about, the foundation of medical ethics by addressing three areas of conceptual presupposition basic to medical ethical theory. First, medical ethics must presuppose a view about the nature of medicine. it is argued that the view required by a cogent medical morality entails that medicine be seen both as a healing relationship and as a practical art. Three ways in which medicine inherently involves values and valuation are presented as important, i.e., in being aimed at the good of health, in being a cognitive art evaluating towards that good, and as a manifestation of a virtuous disposition concerning that good. Finally, a value ontology drawn from these considerations is seen as necessarily underlying medical ethics. A set of three such basic values are promoted as crucial: the value of health; the value of the individual patient; and the value of altruism that mediates the class of potential patients. 相似文献

Bioethics was officially baptized in 1972, but its birth took place a decade or so before that date. Since its birth, what is known today as bioethics has undergone a complex conceptual metamorphosis. This essay loosely divides that metamorphosis into three stages: an educational, an ethical, and a global stage. In the educational era, bioethics focused on a perceived "dehumanization" of medicine by the rising power of science and technology. Remedies were sought by introducing humanities, ethics, and human "values" into the medical curriculum. Ethics was one among the humanistic disciplines, but not the dominant one. In the second era, ethics assumed a dominant role as ever more complex dilemmas emerged from the rapid pace of biological research. As such dilemmas were applied to medical practice, the need for a more rigorous and more formal analysis of their moral status was clear. Philosophically-trained ethicists had an obvious role. They began to teach, write, and profoundly influence medical education and practice. In the third -- and present -- period, the breadth of problems has become so broad that ethicists must, themselves, draw on disciplines well beyond their expertise -- e.g., law, religion, anthropology, economics, political science, psychology, and the like. The era of bioethics as a global enterprise is upon us. The original hope for humanizing medicine has not been overtly successful; however, much has been accomplished of value to patients, the profession, and society. Medical morality has been transformed into a formal, systematic study of a whole range of issues of the greatest significance to humanity. Now the major challenge is one of identity, or inter-relationships and connections between the theoretical and the practical. Bioethics has outgrown its beginnings. 相似文献

College men and women judged whether pairs of stimuli were identical or mirror images. One stimulus of a pair was presented upright; the other was rotated 0°–150° from the vertical. The stimuli were either alphanumeric symbols or unfamiliar letter-like characters of the type found on the Primary Mental Abilities Spatial Relations Test. For each individual, the linear function relating response latency to degree of rotation was computed. The slope of this function was steeper for women than for men. Further, the distribution of slopes was more variable among women, with approximately 30% falling outside the range of distribution for men. Women and men were quite similar in the accuracy of their judgments, the intercepts of the latency functions, and the precision with which the linear function characterized the latency data. It is suggested that the sex difference in the slope of the rotation function may reflect differences in strategies of mental rotation. 相似文献

We used photographic activity schedules to increase the number of play activities completed by children with autism during unstructured time on the playground. All 3 participants engaged in more playground activities during and after training, and they continued to complete activities when novel photographs were introduced. 相似文献
