本文选择了聋哑右利儿童113人和正常右利儿童133人,用八种书写方式书写八个汉字和阿拉伯数字1-10。结果表明;聋哑一年级学生出现的镜像书写人均人次比正常幼儿园儿童少,而其它年级间的比较则无显著性差异;聋哑9—10岁儿童比同年龄组的正常儿童所出现的镜像书写人次多,而在11—12岁组则无显著性差异。通过分析,提出了镜像书写可能存在两个关键期的假说,一是字体熟练程度的关键期,一般在受教育的最初1—2年;另一个是大脑对镜像书写的调节和控制关键期,一般在6岁左右。 相似文献

本文综述了Kandel及其同事们在海兔的研究,以示学习和记忆的神经生物学基础在无脊椎动物的研究进展。全文分四个部份:行为观察、细胞机制、分子水平研究和敏感化与经典条件化的比较。各部份又分若干段落综述。本文认为他们的工作在细胞机制方面可说是有所突破。 相似文献

<易经>是中国最早传入西方的古典文献之一,但其卦爻辞古奥难训,结构复杂,以往的英译本在字、词、句三个层面都存在大量洪译现象.对于英译<易经>卦爻辞来说,泽者应对原文中的通假字、词语的本义和引申义进行详细的考辩,并对原文的句法结构进行细致的分析,包括正确的句读,以及时省略和倒装等语言现象的辨析. 相似文献

本研究选取5、6、8、10岁儿童各32名,采用故事情景来考察儿童处于不可回答问题情况下猜测答案的倾向.研究结果表明:(1)5~10岁儿童在故事情景下面对不可回答问题时存在猜测答案的倾向,且年龄差异不显著.(2)问题形式对儿童猜测答案的倾向有显著影响,较不可回答的开放问题,儿童在不可回答的封闭问题上的猜测答案倾向更强烈.(3)在不可回答的封闭问题上,儿童倾向给出否定的答案. 相似文献

Several writers have suggested that a “support gap” characterizes modern marriages, with women receiving less support from their spouses than men receive from theirs. Although this support gap hypothesis (SGH) is used increasingly to explain marital interaction and satisfaction, there have been few rigorous evaluations of this hypothesis. In particular, existing research on the support gap has not systematically considered (a) different types of social support; (b) differences in provided vs. received support; (c) differences in reported levels of support desire, experience, and satisfaction; or (d) differences in distinct cultural groups with respect to social support in marriage. The present study provided a multidimensional assessment of desired and experienced spousal social support. Participants were recently married men and women (100 Americans and 102 Chinese) who completed questionnaires providing assessments of desired and experienced levels of spousal support for each of 5 support types. Men and women did not differ systematically with respect to the levels of support they experienced from their spouses; however, women reported desiring significantly higher levels of support from their spouses than did men for all 5 types of support. Evaluation of support satisfaction indicated that both American and Chinese women experience gaps with respect to emotional and esteem support; Chinese women additionally experience a gap in network support. These results specify the nature of marital support gaps much more precisely than previous work and suggest several issues to be addressed in future work. 相似文献

In this paper, we explain the influence of co‐worker trust on the effect of employees' openness to experience on their perceptions of their own creativity. We surveyed 199 working professionals in Ireland and found that openness to experience was positively associated with both employees' perceptions of their radical creativity and incremental creativity. In addition, the relationship between openness to experience and incremental creativity was negatively moderated by cognition‐based trust in his or her co‐worker. In conclusion, we discuss the theoretical and managerial implications of our findings and highlight directions for future research. 相似文献

Risk behavior often seems ‘self-defeating’ to the observers. Most people understand the basic health-related knowledge, but some of them still choose to continue risk behaviors, especially for the young. This study aimed to examine time perspective, optimism bias and self control correlated with smoking behavior in Chinese college students. A cross-sectional survey enrolling 3016 university students in Chengdu City, Sichuan Province, China. Influence Factors were identified using multiple logistic regression analyses. Prevalence of current smoking was 20.92% (631 smokers), including 272 daily smokers (9.02%) and 359 non-daily smokers (11.90%). Future-oriented time perspective, general capacity for self-discipline, reliability and ethnicity were protective factors of smoking behavior. Possibility of self-suffering diseases and gender were risk factors of smoking behavior. Smoking in University of Chengdu, China is a severe problem. Results in this research have suggested that irrespective of the smoking level, improving health-related knowledge, time management awareness and self-control ability may contribute to reducing the prevalence of smoking behavior. 相似文献

Effects of varying numbers of Likert scale points on factor structure of the Rosenberg Self‐Esteem Scale

Likert‐type rating scales are among the most widely used tools in psychological research. Different numbers of response categories would likely affect response style, data distribution, reliability, and construct validity. There is a lack of research in factor structure invariance under Likert scales with different numbers of categories. The purpose of this study is to examine the effects of varying numbers of Likert points (4–11) on scale properties such as factor structure, external validity, and latent means based on the Rosenberg Self‐Esteem Scale (M. Rosenberg, 1989 ). The sample consists of 1,807 students from secondary schools in Macau. Confirmatory factor analysis shows that the correlated two‐factor model is the most appropriate one; longitudinal invariance analysis reveals that measurement invariance across Likert scales was satisfied at the scalar level. In addition, latent mean scores on the two factors as well as observed means on the subscales are comparable across Likert scales. Moreover, the measurement model across Likert scales exhibit similar external validity. Although psychometric properties are mostly similar among a different number of points, the 4‐point Likert scale is not recommended for its higher skewness and lower loadings; the 11‐point Likert scale from 0 to 10 is slightly preferred for its higher loadings and composite reliability. 相似文献
