Drawing tests in children diagnosed with dyslexia and dysgraphia were quantitatively compared. Fourteen children with dysgraphia, 19 with dyslexia and 13 normally developing were asked to copy 3 figures: a circle, a square and a cross. An optoelectronic system allowed the acquisition of the drawing track in three-dimensions. The participants’ head position and upper limb movements were measured as well. A set of parameters including movement duration, velocity, length of the trace, Range of Motion of the upper limb, was computed and compared among the 3 groups. Children with dyslexia traced the circle faster than the other groups. In the cross test, dyslexic participants showed a reduced execution time and increased velocity while drawing the horizontal line. Children with dyslexia were also faster in drawing certain sides of square with respect to the other groups. 相似文献

The Cognitive Reflection Test (CRT) is among the most common and well-known instruments for measuring the propensity to engage reflective processing, in the context of the dual-process theory of high-level cognition. There is robust evidence that men perform better than women on this test—but we should be wary to conclude that men are more likely to engage in reflective processing than women. We consider several possible loci for the gender difference in CRT performance, and use mathematical modeling to show, across two studies, that the gender difference in CRT performance is more likely due to women making more mathematical mistakes (partially explained by their greater mathematics anxiety) than due to women being less likely to engage reflective processing. As a result, we argue that we need to use gender-equivalent variants of the CRT, both to improve the quality of our instruments and to fulfill our social responsibility as scientists. 相似文献

心血管事件成为威胁民航飞行安全的主要因素之一.为更及时地发现飞行员冠状动脉病变,提高用无创性常规辅助检查预测飞行员冠状动脉粥样硬化的准确性,对105例飞行员进行血脂、血压、血糖、体重指数、颈动脉彩色多普勒超声检查、运动负荷心电图试验以及64排双源CT冠状动脉造影检查.比较颈动脉粥样硬化与运动负荷心电图试验阳性、高危因素对冠状动脉预测的敏感性和特异性.飞行员的职业特点可能使其冠状动脉粥样硬化早于其他血管床,危险因素较其他辅助检查可能更具意义,必须综合分析各项检查才可能更准确地预测飞行员冠状动脉病变. 相似文献

A binomial test for hierarchical dependency is presented. The null hypothesis is that all members of a population who possess a certain skill are a subset of the members who possess another skill. This hypothesis is basic to the writings of several prominent theorists, such as Gagné and Piaget. The model, assumptions, formula derivations, and procedures for the test are explained. An illustrative example is also provided. 相似文献

樟柳碱所致学习和记忆障碍动物模型的探讨 总被引:2,自引:0,他引:2
本实验采用水迷津法、步下法和步入法,用樟柳碱制备学习和记忆障碍的动物模型。结果表明,樟柳碱(10毫克/公斤)可使小鼠引起学习障碍,其表现为通过水迷津全程的时间延长,而且小鼠进入盲路的错误次数明显增多。樟柳碱(10毫克/公斤)可使小鼠引起记忆障碍,在樟柳碱的影响下,小鼠步下平台或步入暗箱的潜伏期明显缩短,并使它们的错误次数增多。本实验结果进一步表明,测定小鼠的记忆障碍,步入法似乎比步下法更为敏感。 相似文献

This article describes the development and psychometric properties of a measure designed to assess the treatment acceptability of psychological treatments for both adult and child populations. Initial evidence on the Treatment Acceptability Questionnaire (TAQ) indicates that it has a good internal consistency and test-retest stability (over a 3-week period). The pattern of correlations with other measures of treatment acceptability for child-oriented interventions provides evidence of concurrent validity. Suggestions are made regarding the further validation and use of the TAQ. 相似文献

采用认知测试、查阅人类学资料、现场调查和谈话等多种方法,探讨了我国不同生产方式、不同地区和不同民族460名成人的具体认知、抽象认知和认知方式及其与生态文化因素的关系。研究结果基本支持了我们理论上所假设的社会文化因素与具体认知操作、抽象认知操作、认知方式的关系,即狩猎和城市社会的生态环境和生产方式对人施加一种生态压力,增进其个体的具体的和抽象的认知,促使其抽象型认知方式的形成;而在捕鱼、游牧和农耕社会的生态环境和生产方式的作用下,个体倾向于较低水平的具体和抽象认知操作以及具体型的认知方式。紧密的社会结构和强调服从的社会化过程,与其个体较低水平的具体和抽象认知及具体型的认知方式相关联;而松散的社会结构和强调自主性的社会化过程,与较高水平具体和抽象认知操作、抽象型的认知方式相联系。正规教育等现代化因素是促进人认知,特别是抽象认知的有力因素。 相似文献

A Monte Carlo study was conducted to investigate the robustness of the assumed error distribution in maximum likelihood estimation models for multidimensional scaling. Data sets generated according to the lognormal, the normal, and the rectangular distribution were analysed with the log-normal error model in Ramsay's MULTISCALE program package. The results show that violations of the assumed error distribution have virtually no effect on the estimated distance parameters. In a comparison among several dimensionality tests, the corrected version of thex 2 test, as proposed by Ramsay, yielded the best results, and turned out to be quite robust against violations of the error model. 相似文献

It is demonstrated in this paper that two major tests for 2 × 2 talbes are highly related from a Bayesian perspective. Although it is well-known that Fisher's exact and Pearson's chi-square tests are asymptotically equivalent, the present analysis shows that a formal similarity also exists in small samples. The key assumption that leads to the resemblance is the presence of a continuous parameter measuring association. In particular, it is shown that Pearson's probability can be obtained by integrating a two-moment approximation to the posterior distribution of the log-odds ratio. Furthermore, Pearson's chi-square test gave an excellent approximation to the actual Bayes probability in all 2×2 tables examined, except for those with extremely disproportionate marginal frequencies. 相似文献
