Human subjects were exposed to a concurrent-chains schedule in which reinforcer amounts, delays, or both were varied in the terminal links, and consummatory responses were required to receive points that were later exchangeable for money. Two independent variable-interval 30-s schedules were in effect during the initial links, and delay periods were defined by fixed-time schedules. In Experiment 1, subjects were exposed to three different pairs of reinforcer amounts and delays, and sensitivity to reinforcer amount and delay was determined based on the generalized matching law. The relative responding (choice) of most subjects was more sensitive to reinforcer amount than to reinforcer delay. In Experiment 2, subjects chose between immediate smaller reinforcers and delayed larger reinforcers in five conditions with and without timeout periods that followed a shorter delay, in which reinforcer amounts and delays were combined to make different predictions based on local reinforcement density (i.e., points per delay) or overall reinforcement density (i.e., points per total time). In most conditions, subjects' choices were qualitatively in accord with the predictions from the overall reinforcement density calculated by the ratio of reinforcer amount and total time. Therefore, the overall reinforcement density appears to influence the preference of humans in the present self-control choice situation.  相似文献

“以毒攻毒”与中西医结合研究   总被引:8,自引:2,他引:6  
“以毒攻毒”是中医药学一个重要医理和治则。本文介绍了国内外有关“以毒攻毒”的研究进展,以及具有“以毒攻毒”特点的医药研究状况。特别是德国细菌学家贝林等,研制成功破伤风和白喉抗毒素。我国学者张亭栋教授与陈竺教授,继承发掘中药砒霜治疗世界性难治病—急性早幼粒细胞白血病,取得国际领先水平的科研成果等等,表明中西医结合研究是继承发展中医药学的有效方法和途径。  相似文献

Many results concerning the equivalence between a syntactic form of formulas and a model theoretic conditions are proven directly without using any form of a continuum hypothesis. In particular, it is demonstrated that any reduced product sentence is equivalent to a Horn sentence. Moreover, in any first order language without equality one now has that a reduced product sentence is equivalent to a Horn sentence and any sentence is equivalent to a Boolean combination of Horn sentences.  相似文献

Aquinas's conception of the relationship of faith and reason calls into question the arguments and some of the conclusions advanced in contributions to the debate on physician-assisted suicide by David Thomasma and H. Tristram Engelhardt. An understanding of the nature of theology as based on revelation calls into question Thomasma's theological argument in favor of physician-assisted suicide based on the example of Christ and the martyrs. On the other hand, unaided reason calls into question his assumptions about the nature of death as in some cases a good for the human person. Finally, if Aquinas is right about the relationship of faith and reason, Engelhardt's sharp contrast between "Christian" and "secular" approaches to physician-assisted suicide needs reconsideration, although his conclusions about physician-assisted suicide would find support.  相似文献

The basic (negative and positive) methodological maxims of three currents of philosophy of science (logical empiricism, falsificationism, and postpositivism) are formulated. Many of these maxims (stratagems) are controversial, e.g., the stance about the nonsense of metaphysics, and that of its indispensability. The restricted validity of these maxims allows for their unification. Within the framework of most of them there may be a relationship of (synchronic, or diachronic) subordination of the contradicting desiderata. In this vein ten stratagems are formulated. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

We wished to learn if weight perception can be extinguished by studying two patients with right hemisphere brain damage. When lifting weights simultaneously, a patient with right frontal damage was not biased in her judgments of which weight was heavier. By contrast, a patient with right parietal damage reported left-sided weights as being lighter than those on the right. Psychophysical power functions revealed that her awareness of increasing weights on the left was dampened compared to the right when lifting weights individually on each side. Strikingly, her awareness of weight changes on the left was completely abolished when she lifted weights in both hands simultaneously. She demonstrated an unusual split in awareness, being motorically aware of and actively engaged with left-sided weights while being unaware of their incremental changes.  相似文献

本研究以现代教育心理学体系为框架,采用资料整理法,对梁启超的学习心理学思想进行了分析归纳。从中可以看出,梁启超重视学习兴趣,并把无所为、不息、深入研究、找朋友作为保持兴趣的方法;认为做学问的人应具备明敏、密察、别裁、通方等能力和忠实、深切、敬慎、不倦的习惯;并总结出了立志、善观、持敬、明义理、养成读书兴趣等学习方法。  相似文献

授权的测量及其与员工工作态度的关系   总被引:52,自引:3,他引:52  
首先,对Spreitzer的授权量表在中国文化背景下的适用性进行了检验,3家企业395份调查问卷的探索性因素分析和内部一致性分析表明,授权量表具有较好的效度和信度;20家企业942份调查问卷的验证性因素分析和内部一致性分析进一步验证了授权量表的效度和信度,这表明Spreitzer的授权四维模型在中国得到了验证,其编制的授权量表在中国具有较强的适用性。然后,利用20家企业942份调查问卷的结果,采用结构方程模型技术对授权与员工满意度、组织承诺、离职意向与工作倦怠等员工工作态度变量之间的关系进行了交叉验证分析,结果表明,工作意义对员工满意度与组织承诺有正向的影响,对离职意向与工作倦怠有负向的影响;自主性对员工满意度与组织承诺有正向的影响;自我效能对组织承诺有正向的影响  相似文献
