耳科学在人类与耳部疾病的斗争中兴起了19世纪,在本世纪随科学技术的发展而获得迅速发展,特别是抗菌素和手术显微镜的出现,使耳显同外科技术不断提高,不仅能彻底地祛除耳部感染,而且可以有效地提高听力,耳科学家在聋病的治疗过程中,已能够有效地治疗传导性耳聋,但仍面临着治疗神经性耳聋的挑战,在现代科学技术革命的推动下,随着分析子生物学,细胞生物学等新技术的发展,在21世纪,人类必定能够彻底治疗聋病。 相似文献

论中西医结合的过程与层次 总被引:2,自引:0,他引:2
韩乾国 《医学与哲学(人文社会医学版)》1999,20(6):12-15
中西医结合是一个长期困扰人们的难题。中医理论研究人体外部现象的变化规律,以古代哲学思想为指导,具有整体联系、动态把握的合理内核。而目前现代医学对人体结构和功能的认识,并不能完全揭示生命现象本质,因而也不能完全解释中医现象。这种认识有一个不断发展和深化的过程,自然辩证法观点认为层次越低、结合越紧密。分子导次是具有生物意义的最低层次。人类“基因组”计划的实现可能在一个新的高度阐明人体本质,也使中医现象 相似文献

Ratings of familiarity and pronounceability were obtained from a random sample of 199 surnames (selected from over 80,000 entries in the Purdue University phone book) and 199 nouns (from the Ku?era-Francis, 1967, word database). The distributions of ratings for nouns versus names are substantially different: Nouns were rated as more familiar and easier to pronounce than surnames. Frequency and familiarity were more closely related in the proper name pool than the word pool, although both correlations were modest. Ratings of familiarity and pronounceability were highly related for both groups. A production experiment showed that rated pronounceability was highly related to the time taken to produce a name. These data confirm the common belief that there are differences in the statistical and distributional properties of words as compared to proper names. The value of using frequency and the ratings of familiarity and pronounceability for predicting variations in actual pronunciations of words and names are discussed. 相似文献

汉字词识别过程的形,音,义编码作用的研究 总被引:7,自引:0,他引:7
本文通过两个实验,采用汉字词形、音、义特征匹配任务,探讨了影响汉字词的形、音、义编码与提取方式的有关因素。实验一发现在速示条件下,对汉字词再认的成绩并不受字词的使用度的影响,反应时无明显变化,而主要受编码加工的深度影响。在形、音、义特征加工中,对音码的加工时间最长,再认的正确率最低;义码的加工时间较短,再认正确率最高;形码的反应时及再认成绩介于音码与义码之间。实验二在非速示条件下也获得了相同的结果。研究结果表明,在汉字词的形、音、义特征中,存在着编码加工深度的差异。 相似文献

We investigated whether a simplified habit reversal treatment eliminates fingernail biting and related oral-digital habits exhibited by individuals with mild to moderate mental retardation. Although simplified habit reversal did little to decrease the target behaviors for 3 of 4 participants, simplified habit reversal plus additional treatment procedures decreased the behavior to near-zero levels for all participants. These procedures included remote prompting, remote contingencies involving differential reinforcement plus response cost, and differential reinforcement of nail growth. Limitations of habit reversal for individuals with mental retardation along with directions for future research involving therapist-mediated treatment procedures, particularly those involving remote prompting and remote contingencies, are discussed. 相似文献

That similar words can prime one another is not news. However, this phenomenon can be exploited to make inferences about the organization of conceptual representations. What types of similarity matter? Although there is evidence that similarity of function, shape, and even manner of manipulation is reflected in semantic memory, evidence for organization on the basis of color similarity is sparse. This lack of evidence is surprising: Intuition suggests that color is a prominent feature of many object concepts. The research reported here clarifies this puzzle and illustrates the dynamic nature of conceptual representations. Our research demonstrates color-based priming (e.g., "emerald" primes "cucumber") in participants who completed a Stroop color-naming task before a priming task. Notably, the size of the Stroop effect predicted the size of the priming effect. When the order of tasks was reversed, priming effects were eliminated. By demonstrating that both extrinsic and intrinsic factors can influence conceptual activation, our findings have implications for theories of semantic memory. 相似文献

论马克思主义的整体性(上) 总被引:1,自引:0,他引:1
近年来,随着 "马克思主义理论"被正式确立为国家一级学科,"马克思主义学院"在全国高等院校纷纷成立,国内马克思主义研究在表面上也呈现出一派热闹非凡的景象。于是马克思主义的整体性问题被提了出来。然而,与这种表面上热闹的景象形成鲜明对照的是,真正从心灵深处认同、信仰马克思主义的人并不很多。这种悖论式的现象不能不引起我们足够的重视。对于研究马克思主义的理论工作者而言,必须对眼前令人眼花缭乱的马克思主义 "热"进行 "冷"思考,就是说,必须认真地、郑重地提出并弄清这样一个问题: 马克思主义就其本义而言,是站在大众立场、为大众立言、为 相似文献

In this cross-cultural study, 115 Hong Kong Chinese and 117 Brazilian college students described a childhood peak-experience
(occurring before the age of 14) and provided a self-rating on its enduring impact. Among various categories of peak-experiences,
both Hong Kong Chinese and Brazilians reported interpersonal joy most frequently; the second most frequently reported category
was external achievement for the Hong Kong sample and developmental landmark for the Brazilian sample. Compared with Brazilians’
narratives, those of Hong Kong Chinese were more social-focused, involving greater number of other people, but less specific.
These characteristics of autobiographical memory, i.e., memory focus (self vs. social), memory specificity (specific vs. general),
and the number of other people involved, significantly mediated the relation between culture and interpersonal joy. The present
findings have extended research on peak-experiences to cross-cultural contexts and incorporated measures of autobiographical
memory to unpack cultural variations in these two collectivist societies. 相似文献
