重建权利和义务的平衡 总被引:3,自引:0,他引:3
以往我们过多地强调权利而忽视义务的教育使一些人错误地认为人们只有权利而不必尽义务。第二次世界大战后第二代人的一个代言人曾经提出一种新的、来自责任方面的自由,这种自由是指,人 相似文献

我与我的朋友Z.皮利辛在饭后曾进行过一场辩论。它涉及皮利辛(Pylyshn)所提出的下述论断:“如果没有一个关于心理表征的内容同一性的精确规定的概念,那么认知心理学就是不可能的。”后来我想到,拒绝这一论断的理由直接与D.戴维森对于意义理论和心智哲学的众所周知的影响有联系,因而在皮利辛的允许和宽恕(但愿如此)下,我便决定在本文中主要阐述我反对他的论点的理由。 相似文献

在今天这个已变得如此狭小的世界上,我们所面临的全球性问题,尤其是核灾难对人类的威胁,要求在各民族之间建立起一种理性的共存格局。从现实主义角度来看,用理性来协调人们的行为举止,不是由于其自身,而是由于明显的物质方面的生存危机,今天具有前所未见的发展机遇。最迟自十八世纪启蒙运动开始,科学已经被看作是最佳的理性 相似文献

Effects of differences between stimuli, responses, and reinforcer rates on conditional discrimination performance 总被引:5,自引:5,他引:0 下载免费PDF全文
In a discrete-trial conditional discrimination procedure, 4 pigeons obtained food reinforcers by pecking a key with a short latency on trials signaled by one stimulus and by pecking the same key with a long latency on trials signaled by a second stimulus. The physical difference between the two stimuli and the temporal separation between the latency values required for reinforcement were varied factorially over four sets of conditions, and the ratio of reinforcer rates for short and long latencies was varied within each set of conditions. Stimulus discrimination varied directly with both stimulus and response differences and was unaffected by the reinforcer ratio. Sensitivity to reinforcement, estimated by generalized-matching-law fits to the data within each set of conditions, varied directly with the response difference but inversely with the stimulus difference arranged between sets of conditions. Because variations in stimulus differences, response differences, and reinforcer differences did not have equivalent effects, these findings question the functional equivalence of the three terms of the discriminated operant: antecedent stimuli, behavior, and consequences. 相似文献

In a previous study of two-choice reactions, pairings of spatial stimuli with bimanual presses made on a keyboard and verbal stimuli with unimanual aimed movements made on a display screen showed higher set-level compatibility than the opposite pairings; element-level compatibility (i.e., mapping) effects were also larger for the conditions with high set-level compatibility than for those whose set-level compatibility was low. In the 4 experiments described here, the relevant factors were isolated, allowing the determinants of those compatibility differences to be evaluated in more detail. Forty-eight students participated in Experiment 1, and 24 each in Experiments 2, 3, and 4. The primary determinant of the set-level compatibility variation was whether the response alternatives involved 1 or 2 effectors, but the differences in element-level compatibility effects were determined primarily by the distinction between responding on the screen as opposed to on the keyboard. Implications for models of stimulus-response compatibility are examined. 相似文献

This paper examines ethical issues related to medical practices with children and adults who are members of a linguistic and cultural minority known as the DEAF-WORLD. Members of that culture characteristically have hearing parents and are treated by hearing professionals whose values, particularly concerning language, speech, and hearing, are typically quite different from their own. That disparity has long fueled a debate on several ethical issues, most recently the merits of cochlear implant surgery for DEAF children. We explore whether that surgery would be ethical if implants could deliver close to normal hearing for most implanted children, thereby diminishing the ranks of the DEAF-WORLD. The ethical implications of eugenic practices with the DEAF are explored, as are ethical quandaries in parental surrogacy for DEAF children, and their parallels in transracial adoption. 相似文献
