P. S. Greenspan 《The Journal of Ethics》1998,2(2):103-122
The paper outlines a view called social (or two-level) response-dependency as an addition to standard alternatives in metaethics that allows for a position intermediate between standard versions of internalism and externalism on the question of motivational force. Instead of taking psychological responses as either directly supplying the content of ethics (as on emotivist or sentimentalist accounts) or as irrelevant to its content (as in classical versions of Kantian or utilitarian ethics), the view allows them an indirect role, as motivational props to moral teaching and thus to the general institution of moral discourse. However, they are not implied by any particular moral judgment (or speaker), so that amoralism comes out as possible. The response that defines the distinctively moral notion of wrong on this account is the second-level (social) response of forbidding some behavior; but this is ultimately to be understood in terms of (variable) individual reactions. Natural human emotion tendencies thereby constrain the content of ethics, while allowing for some degree of social variation in moral codes. 相似文献

研究了41名弱智儿童。采用时间样本的方法收集材料,以期从动态角度了解弱智儿童在上课时和自由活动时的行为表现。按园别和智力落后程度两个方面对被试在上课时的8大类行为和自由活动时的7大类行为进行了分析。结果发现:班级人数、不同教学方法和智力落后程度与弱智儿童的行为表现有关。还对收集材料的方法、园别和智力落后程度与弱智儿童的行为表现的关系、高频率的自娱活动等,进行了讨论。最后,根据研究结果对教师提出了教学建议。 相似文献

The fall of the Berlin Wall, which separated West Germans and East Germans for decades, led to emotional catastrophe among the reunited peoples. The authors conducted a psychological research program in Berlin to analyze individual and interpersonal processes in the reunification. They describe four categories used to pinpoint different (largely unconscious) levels of coping and defense strategies used to deal with the changes: control, splitting, symbiosis, and integration.Thomas Krauss, Dr. phil., is a family therapist and teaching supervisor.

F. J. McGuigan 《International journal of stress management》1994,1(1):103-113
The American Association for the Advancement of Tension Control was founded in 1973 as an interdisciplinary effort encompassing the fields of dentistry, education, medicine, physical therapy, psychology, and speech pathology. The broad purpose was to facilitate the acquisition, dissemination, and application of sound knowledge for the benefit of society throughout the world. Annual meetings were held through 1978 with dues-paying members numbering almost 1000. Name changes were first to the International Stress and Tension-Control Association and then to the International Stress Management Association (ISMA) whereupon international meetings were held in 1979, 1981, 1983, 1988, and 1992. ISMA is flourishing, with meetings planned for The Netherlands (1995) and Australia (1996). 相似文献

Infarct si?e (number of 1-mm2 pixels in the lesion) on CT scans of 30 aphasia patients was obtained with a semiautomated computer program. The mean number of lesion pixels present per slice containing lesion was approximately 500 for mild aphasias (transcortical motor and conduction), 700 for Wernicke's, 1000 for Broca's, 1500 for mixed, and 2000 for globals. These differences were significant for of the group pairwise comparisons. When lesion locus was controlled for in the anterior/posterior plane, 73–100% of the aphasia patients were correctly classified as to type of aphasia by a discriminant analysis utilizing only the number of lesion pixels present on two CT slices. Different slice combinations were used for different aphasia group comparisons. There was a significant correlation between severity of aphasia and lesion size. There was a significant correlation between lesion size and the CT numbers in the lesion. This type of analysis may be useful to predict the prognosis for recovery potential in aphasics who have CT scans performed at 2 months poststroke. 相似文献

The five participants in this dialogue critically discuss Zeno of Elea's paradox of Achilles and the tortoise. They consider a number of solutions to and restatements of the paradox, together with their philosophical implications. Among the issues investigated include the appearance-reality distinction, Aristotle's distinction between actual and potential infinity, the concept of a continuum, Cantor's continuum hypothesis and theory of transfinite ordinals, and, as a solution to Zeno's puzzle, the distinction between infinite and indeterminate or inexhaustible divisibility. 相似文献
