周易阴阳符号与二进制算术符号比较 总被引:2,自引:1,他引:1
周易符号和二进制算术符号是两种截然不同的文化代码及其规则.它们分别代表了东西方文化最深层的文化构造原则和最高的集体智能。本文试运用符号学的观点.通过对这两种符号的比较。概括出有标记和无标记、约定性和选择性两种文化代码规则范畴,并进一步揭示出中西文化的差异。 相似文献

20世纪90年代以来,从认知神经科学的角度揭示语言及其它认知的脑机制成为科学研究的前沿与热点。研究各种脑损伤导致的特异性语言障碍,为探索语言和其它认知的结构、加工,及大脑不同部位在语言和其它认知活动中的功能增添了一条新的途径。同时也对临床失语症的诊断与康复起了很多积极的作用。汉语在世界语言体系中具有其独特性,对汉语的语言障碍及其脑机制的研究将为完善人类语义知识理论、语言的表征与加工模型有重要贡献,也为发展汉语失语症针对性的康复方案提供理论和实践基础 相似文献

已有研究表明海洛因成瘾者风险决策能力受损, 但少有研究关注不同幅度金钱奖赏对戒断期海洛因成瘾者风险决策的影响以及这种影响是否会受到金钱奖赏类型的调节。因此, 本研究使用气球模拟风险任务(BART), 通过两个实验探究不同幅度虚拟和真实金钱奖赏对海洛因戒断者风险决策的影响。结果显示, 在虚拟奖赏情景下, 海洛因戒断者未爆破气球按键次数和爆破气球个数均显著大于正常组被试, 以及两组被试在25分奖赏条件下的未爆破气球按键次数和爆破气球个数均显著大于1分奖赏; 而在真实奖赏情景下, 海洛因戒断者未爆破气球按键次数和爆破气球个数均显著小于正常组被试, 以及两组被试在25分奖赏条件下的未爆破气球按键次数和爆破气球个数均显著小于1分奖赏。研究结果表明, 金钱奖赏类型和金钱奖赏幅度会影响被试的风险决策行为。在虚拟奖赏情景下, 两组被试的风险偏好水平随着奖赏幅度的增加显著升高, 但是戒断期海洛因成瘾者的风险偏好水平高于正常组被试; 而在真实奖赏情景下, 两组被试的风险偏好水平随着奖赏幅度的增加显著降低, 同时戒断期海洛因成瘾者的风险偏好水平低于正常组被试。 相似文献

More than 600,000 U.S. children are reported for physical abuse annually. Risk factors are proposed in the literature, but a comprehensive, national assessment of risk factors and support services has not been conducted. An analysis of national data from the National Child Abuse and Neglect Dataset revealed that domestic violence, parental alcohol and drug use, prior child abuse and neglect, public assistance receipt, and child behavior problems are associated with higher odds of substantiated physical abuse reports, compared to unsubstantiated reports. Most families, however, failed to receive relevant support services for any of these risk factors. Screening by physicians, child protection workers, and others for these risk factors could help identify children at increased risk for physical abuse and inform prevention efforts and support-service provision. 相似文献

The aim of the present work was to examine cultural differences in the development of speed of information processing. Four samples of US children (N = 509) and four samples of East Asian children (N = 661) completed psychometric measures of processing speed on two occasions. Analyses of the longitudinal data indicated that, although processing speed was comparable among US and East Asian children at the youngest age (~4.5 years), it developed more rapidly in some but not all of the East Asian samples. Results are discussed in terms of factors that may promote more rapid development of processing speed in some East Asian cultures. 相似文献

During sentence reading, low spatial frequency information afforded by spaces between words is the primary factor for eye guidance in spaced writing systems, whereas saccade generation for unspaced writing systems is less clear and under debate. In the present study, we investigated whether word-boundary information, provided by alternating colors (consistent or inconsistent with word-boundary information) influences saccade-target selection in Chinese. In Experiment 1, as compared to a baseline (i.e., uniform color) condition, word segmentation with alternating color shifted fixation location towards the center of words. In contrast, incorrect word segmentation shifted fixation location towards the beginning of words. In Experiment 2, we used a gaze-contingent paradigm to restrict the color manipulation only to the upcoming parafoveal words and replicated the results, including fixation location effects, as observed in Experiment 1. These results indicate that Chinese readers are capable of making use of parafoveal word-boundary knowledge for saccade generation, even if such information is unfamiliar to them. The present study provides novel support for the hypothesis that word segmentation is involved in the decision about where to fixate next during Chinese reading. 相似文献

We examined the differential item functioning (DIF) of Rosenberg's (1965 ) Self‐Esteem Scale (RSES) and compared scores from U.S. participants with those from 7 other countries: Canada, Germany, New Zealand, Kenya, South Africa, Singapore, and Taiwan. Results indicate that DIF was present in all comparisons. Moreover, controlling for latent self‐esteem, participants from individualistic countries had an easier time reporting high self‐esteem on self‐competence‐related items, whereas participants from communal countries had an easier time reporting high self‐esteem on self‐liking items ( Tafarodi & Milne, 2002 ). After adjusting for DIF, we found larger mean self‐esteem differences between the countries than observed scores initially indicated. The suitability of the RSES, and the importance of examining DIF, for cross‐cultural research are discussed. 相似文献
