罗素与他曾遇见过的,并就哲学问题进行过交流的好几位实用主义哲学家相互影响。这些相互影响同罗素与他的朋友和合作者如摩尔、怀特海、维特根斯坦等之间的相互影响性质不同。这是一种敌对的性质。事实上罗素与唯心主义者的相互影响也是如此。不同的地方只在于罗素本人曾经历新黑格尔主义这一阶段。至于就实用主义来说,罗素自始至终把它作为对手,实用主义者的主张对他来说是不相容的。尽管罗素自己思想发展过程中在这一点上没有改变过,但是,正如我们将看到的,他思想上的变化使他比他自己承认的更接近这些实用主义的观点。1896年,罗素在他第一次访问美国时结识了詹姆斯和皮尔斯。后来罗素又从W.维尔比(Welb 相似文献

创造性思维是适应性思维或称重新概念化。其绝大部分不是外显行为,而是内隐的认知。我们日常大部分认知和行为是自动化的。它们满足着我们的日常需要。而满足我们需要的方式有一定导向,甚至变得刻板严格。在我们日常生活的所有方面,象饮食社交、宗教艺术、学术训练等等,我们都发展了动作的、自动化的认知和行为来满足基本的需要。我们去餐馆吃饭来满足饥饿的需要,与亲属的社会交往在家庭团聚中已经仪式化,我们的医生每月 相似文献

A literature search was conducted on studies of new drugs used with patients with schizophrenia reported by U.S. and non-U.S. researchers from 1966–1993, yielding 41 U.S., and a total of 24 other non-U.S. studies, among them 11 British studies. Results of the U.S. and non-U.S. studies were pooled separately and compared. Among several comparable conditions discussed, the lack of any data on suicides in the U.S. studies was observed. For a second statistical analysis of suicide rates ‘person-years’ were calculated to adjust for differing washout durations. The results obtained include findings that the percentage of patients relapsing in U.S. studies was slightly lower (37.9%) than in non-U.S. studies (46%); the percentage of patients dropping out in U.S. studies (10.5%) was higher than in non-U.S. studies (7.6%); known location of dropout patients in U.S. studies was 1.7%, compared to 2.6% in non-U.S. studies. The most interesting finding was that no suicides were reported in U.S. studies, compared to 0.6% of patients reported in British studies. Some U.S. studies used ‘challenge doses’, such as amphetamines or L-dopa; no non-U.S. studies reported their use. Compared to U.S. studies, those by non-U.S., and particularly British, researchers appeared to report adverse events in their studies. ‘Challenge’ drugs were not used; suicides were reported. It is estimated that the probability that no patients suicided who participated in the U.S. is small—one in 500. 相似文献

Languages differ in their phonological structure and physcholinguists have begun to explore the conseqence, of this fact for speech perception. We review research documenting that listeners attune their perceptual processes finaly to exploit the phonological regularities of their nativ language. As a consequence, these perceptual process are fill-adapted to listening to languages that do not display such, regularities. Thus, not only do late language-learners have trouble speaking a second language, also they do not hear it as native speakers do; worse, they apply their native language listening prosedures which may actually interfere with successful processing of the non-native input. We also present data from studies on infants showing that the initial attuning occurs early in life; very yong infants are sensitive to the relevant phonological regularities which distinguish different languages, and quickly distinguish the native language of their environment from languages with different regularities. 相似文献

The auditory cortex of the mustached bat shows complex multiple frequency maps, because cortical neurons in several areas are tuned to particular combinations of signal elements. Different types of combination-sensitive neurons form computational maps in which information-bearing parameters for echolocation (biosonar) are represented systematically. Neuronal response properties and multiple-frequency and computational maps were considered to be created solely by divergent-convergent interactions of neurons in the 'ascending' system. However, we have found that the 'corticofugal' system also plays an important role. Neurons in an iso-best frequency (or echo delay) 'minicolumn' of the auditory cortex augment the auditory responses of subcortical neurons tuned to that frequency (or echo delay) and sharpen their tuning. At the same time, they reduce the response and shift the tuning of subcortical neurons tuned to other frequencies (or echo delays) away from the best frequency (or delay) of the cortical neurons. Cortical neurons mediate a highly focused positive feedback, incorporated with widespread lateral inhibition, via corticofugal projections. This 'egocentric selection' is expected to play an important role in self-organizing the central auditory system. 相似文献
