Above suspicion: Cognitive and intentional aspects of the ability to lie

This paper looks at the attribution of the ability to lie and not at lying or lies. It also departs from more familiar approaches by focussing on the appraisal of an ability and not on the ability in itself. We believe that this attribution perspective is required to bring out the cognitive and intentional basis of the ability to lie.     

The impact of consonant clusters on preschool children''s phonemic awareness: A comparison between readers and nonreaders

Preschool children's ability to segment and blend real words and nonsense words, with and without consonant clusters was investigated in two experiments. In the first experiment, preschool children's ability to segment real words into phonemes was examined. Readers performed better than nonreaders on a phoneme counting task and words containing consonant clusters were harder to segment compared to words without consonant clusters. In experiment two, the ability to segment and blend nonsense words was investigated. Nonreaders had significantly more difficulty with nonsense words compared to readers in both a phoneme synthesis and a phoneme analysis task. A two-way interaction between reading level and word type showed that nonsense words containing consonant clusters were particularly difficult for nonreaders. The results were discussed in relation to theories suggesting that syllables consist of an onset and a rime.     

Evaluating young children''s cognitive capacities through computer versus hand drawings

Young normal and handicapped children, aged 3 to 6 years, were taught to draw a scene of a house, garden and a sky with a computer drawing program that uses icons and is operated by a mouse. The drawings were rated by a team of experts on a 7-category scale. The children's computer- and hand-produced drawings were compared with one another and with results on cognitive, visual and fine motor tests. The computer drawing program made it possible for the children to accurately draw closed shapes, to get instant feedback on the adequacy of the drawing, and to make corrections with ease. It was hypothesized that these features would compensate for the young children's limitations in such cognitive skills, as memory, concentration, planning and accomplishment, as well as their weak motor skills. In addition, it was hypothesized that traditional cognitive ratings of hand drawings may underestimate young children's intellectual ability, because drawing by hand demands motor skills and memory, concentration and planning skills that are more developed than that actually shown by young children. To test the latter hypothesis, the children completed a training program in using a computer to make drawings. The results show that cognitive processes such as planning, analysis and synthesis can be investigated by means of a computer drawing program in a way not possible using traditional pencil and paper drawings. It can be said that the method used here made it possible to measure cognitive abilities "under the floor" of what is ordinarily possible by means of traditionally hand drawings.     

4-5年级学生的空间表征与几何能力的相关性研究

本研究是“学生空间能力和几何能力关系”研究的一部分,以小学4、5年级学生为被试(共117人),以空问表征能力测验和几何能力测验为测验工具,初步探讨了学生空间表征与几何能力的关系。对数据结果的分析表明:①就总成绩而言,五年级学生的空间表在成绩明显高于四年级学生的成绩,但并不是空间表征的所有方面都存在着显著的年级差异;②就空间测验的总成绩而言,无论是四、五年级分别考察还是总起来考察,空间成绩与几何成绩之间的相关显著,但就各个分项而言,并不是空间测验的各项都与几何测验成绩有显著相关;学生的几何成绩在一定程度上可通过回归方程:Y_i=0.5736X_i+0.7635加以预测。     

TOWARD A GENERAL THEORY OF HUMAN CREATIVITY

Abstract. The presence of a basic and general form of creativity in people is investigated through experiments with music. The results indicate that "generative" creativity—-the ability to spontaneously generate a music by varying a basic set of musical elements—is a basic human endowment, unlike "constructive" creativity—-the type of creativity exhibited by composers and other artists—-which is the result of training and the spehal development of faculties. Generative creativity's coming to the fore in contemporary people would contribute to the development of the personality and help bring about more fulfilled, better balanced people and societies.     

The elderly and high technology medicine: A case for individualized,autonomous allocation

The issues involved in decision making about the aggressiveness of future medical care for older persons are explored. They are related to population trends, the heterogeneity of older persons and a variety of factors involved in individual preferences. Case studies are presented to illustrate these points, as well as a review of pertinent literature. The argument is offered that, considering these many factors, a system of flexible, individualized care by informed patient preference, is more rational than the rationing of technological services by age.

大学生镜像书写及其机制探讨

本研究选择60名右利大学生(男女各半)为被试,在笔划水平上对十四种不同书写方式下快速书写时所出现的自发性镜像书写进行了研究。所有被试随机分为人数相等的实验、对照两组,组内男女各半。对实验组加以注意干扰。书写内容是十个阿拉伯数字(0—9)及十三个汉字组成的一句话。本研究结果表明:注意干扰、感觉的反馈调节,书写内容的特点是影响镜像书写出现的重要因素。作者在分析国内外有关镜像书写工作的基础上,进一步提出了“稳态系统”理论。     

The asymptotic posterior normality of the latent trait in an IRT model

It has long been part of the item response theory (IRT) folklore that under the usual empirical Bayes unidimensional IRT modeling approach, the posterior distribution of examinee ability given test response is approximately normal for a long test. Under very general and nonrestrictive nonparametric assumptions, we make this claim rigorous for a broad class of latent models.This research was partially supported by Office of Naval Research Cognitive and Neural Sciences Grant N0014-J-90-1940, 442-1548, National Science Foundation Mathematics Grant NSF-DMS-91-01436, and the National Center for Supercomputing Applications. We wish to thank Kumar Joag-dev and Zhiliang Ying for enlightening suggestions concerning the proof of the basic result.The authors wish to thank Kumar Joag-Dev, Brian Junker, Bert Green, Paul Holland, Robert Mislevy, and especially Zhiliang Ying for their useful comments and discussions.
