运用词汇判断任务,考察了汉语双字词识别中的多义性效应。实验一运用2个真字任意组合构成的假词(如:镜社)作填充材料,发现多义词识别的优势效应仅仅存在于错误率中。实验二运用与源真词(如:冲锋)同音形似的假词(如:冲烽)作填充材料,促使被试更多地在语义水平上做出判断,结果发现很强的多义词识别的优势效应,这种效应主要表现在低频词上。两个实验结果表明,在词汇判断中用不同的假词作填充词会影响被试的词汇判断策略,从而在不同水平上通达词义。最后,用反馈模型对实验结果进行了解释。 相似文献

汉语发展性阅读障碍亚类型的初步探讨 总被引:12,自引:0,他引:12
以阅读水平匹配组为参照对29名汉语发展性阅读障碍儿童的认知缺陷模式进行了分析,并考察了不同亚类型阅读障碍儿童的汉字识别模式。结果表明汉语发展性阅读障碍存在不同的亚类型,以语音缺陷型、快速命名缺陷型及两者结合的双重缺陷型为主,与英语国家研究中的双重缺陷假设一致。语音缺陷型儿童汉字识别时有更多的语义错误,对声旁中的部分语音线索不敏感;快速命名缺陷型儿童汉字识别时依赖声旁语音线索,表现出阅读发展的一般延迟;双重或多重认知缺陷型是阅读损伤最严重的亚类型 相似文献

微观发生法:聚焦认知变化 总被引:11,自引:1,他引:10
微观发生法通过在变化发生的整个过程中对行为进行高密度观察和反复试验分析,可以提供关于认知变化的路线、速率、广度、来源以及变化模式的多样性等方面的精细信息,对于理解心理变化的机制有重要意义。该文论述了从发生法到微观发生法的演变过程、微观发生法的研究设计及其合理性与有待解决的问题。 相似文献

Happiness is associated with both extraversion and neuroticism, and extraversion is generally considered the more important. A recent study of happy introverts has shown that extraversion is not always an essential correlate of happiness, and an extensive meta-analysis has found that neuroticism is a greater predictor of both happiness and life satisfaction. It is suggested that the reason for the importance of neuroticism having been overlooked in the past, is the difficulty of handling the idea that (positive) happiness is related to the absence of a (negative) construct. This difficulty could be resolved by the reversal of neuroticism into an alternative and positive concept of “emotional stability”. Happiness could then be regarded as being associated with two positive qualities. With this change of emphasis, a short empirical study has been made of the relationships between happiness as measured by the Oxford Happiness Inventory (OHI) and extraversion and emotional stability. In bivariate and partial correlation, emotional stability was more strongly associated with happiness than extraversion, and accounted for more of the total variability in multiple regression. Emotional stability was also the greater correlate for a majority of the 29 items of the OHI, and the sole significant predictor of the happiness of younger people. 相似文献

The modulatory influence of literacy on the cognitive system of the human brain has been indicated in behavioral, neuroanatomic, and functional neuroimaging studies. In this study we explored the functional consequences of formal education and the acquisition of an alphabetic written language on two- and three-dimensional visual naming. The results show that illiterate subjects perform significantly worse on immediate naming of two-dimensional representations of common everyday objects compared to literate subjects, both in terms of accuracy and reaction times. In contrast, there was no significant difference when the subjects named the corresponding real objects. The results suggest that formal education and learning to read and to write modulate the cognitive process involved in processing two- but not three-dimensional representations of common everyday objects. Both the results of the reaction time and the error pattern analyses can be interpreted as indicating that the major influence of literacy affects the visual system or the interaction between the visual and the language systems. We suggest that the visual system in a wide sense and/or the interface between the visual and the language system are differently formatted in literate and illiterate subjects. In other words, we hypothesize that the pattern of interactions in the functional-anatomical networks subserving visual naming, that is, the interactions within and between the visual and language processing networks, differ in literate and illiterate subjects. 相似文献

The presented paper substantiates the principle that values are an immanent component of science and any rational cognitive
activity. This principle belongs to the European cultural tradition starting from the book of Genesis of the Old Testament,
the values of certainty in the antique Greek philosophy and Francis Bacon's coincidence of knowledge and power. Values in
science form complicated structures inconnection with different types of knowledge including “the knowledge that”, empirical
evidence, various types of generalizations or rules, methods, directions, algorithms, “the knowledge how”, “the knowledge
why” or other types of knowledge. Since the assignments of different types of values are the products of a decision-making,
it is useful to distinguish many types of decision-making, especially semantic decision-making, information decision-making
and decision-making with distinctly pragmatic dimensions. The values assignable to scientific activities and their results
also include their social recognition, respect and prestige granted to knowledge and bearers of knowledge by society and social
groups or communities. Knowledge generation and the rational and justified application of the achieved and acceptable impacts
are also connected with decision-making procedures, values and criteria of social acceptance.

乾卦六龙的天文科学含义新解 总被引:2,自引:1,他引:1
本文认为乾卦六爻爻辞所说的“六龙”各种状态是苍龙星在一个回归年中所运动的不同天象。这种天象的观测年代,过去的研究都根据秦汉“二月二,龙抬头”等记载认为是春秋秦汉的实际观测。我们认为,其观测年代至少应早于西周晚期以前的乾卦爻辞形成年代;并根据秦汉易学中“建子起乾龙”“九二当太簇之月”的文献记载、甲骨文中“正月见龙”的记载以及仰韶文化时期的“(恙)和御龙”蚌塑图有力地证实了六龙天象的观测年代当与五帝虞夏的年代相当。同时认为,六龙天象的观测是先民们创制“六龙季历”的天文基础.“六龙季历”则是在古老的易占系统中流传的“易以三百六十析为期”的、刨制于原始社会晚期的一种太阳历。 相似文献
