书写字体的性别差异研究

从珠海市中小学一年级至初中三年级随机选出５４０名学生,要求他们每个人抄一段４００字左右的短文,收回抄写卷５４０份。４０名有经验的教师,对书写者的性别做出判断,并回答一份关于判断男女笔迹的依据的问卷。结果表明：１．小学低年级男女生的字体没有明显的性别差异,到中高年级以后,性别差异才明显地表现出来。二、三年级之间,五、六年级之间是差异形成的两个加速期。２．判断者对小学低年级书写者的性别的判断不准确,主要是由于将女生的字体误判为男生的字体而造成的。３．男女生字体的差异主要表现在五个方面,即字体大小程度,字的力度、字体的刚劲度、字的工整度和字的棱角度。     

字符的知觉表征及其启动

实验以英文单词,汉字和图片为材料,采用速示补笔测验测量了大脑左右半球的启动效应。结果是,如果学习与测验的字体和大小不变,则视觉启动右半球高于左半球。其他材料不产生这种效应。这表明,至少有一个分离的系统对构成启动的汉字的视觉表征进行编码,此系统在右半球表征形状特异形状特异信息更有效;对字符抽象特征的表征,两半球无显著差异,速示补笔测量的是前语义水平的知觉表征,是一种知觉（数据驱动）内隐记忆测验。     

关于历史上伊斯兰教与中国社会相适应问题的思考

本文意在说明我国伊斯兰教历史上就有与中国社会相适应的传统。认为认识和把握这个传统对今天和今后妥善处理中国伊斯兰教问题很有必要。在此认识基础上,作者通过这种相适应的含义和程度、背景和条件,方式和过程、矛盾及其解决、结果和立论、特点和意义六个方面进行了探索。     

小学优等生与学习不良学生智力特征的比较研究

本研究运用 WISC-CR研究了小学阶段一、三、五年级优生与学习不良儿童在智力水平与智力结构上的异同。研究结果表明 :1优生与学习不良儿童在智力水平上有十分显著的差异 ,优生的平均智商为 1 2 0 .1 ,学习不良儿童的平均智商为 97.4;2优生在操作分量表与语言分量表上的得分比较均匀 ,但学习不良儿童的操作智商显著地优于语言智商 ;3优生与学习不良儿童在智力结构上也不尽相同 ,优生在词汇、积木、类同等分测验上的得分高 ,在算术、背数、排列等分测验上的得分较低 ;学习不良儿童在拼图、译码、填图、词汇等分测验上的得分较高 ,在常识、算术、背数等上的得分较低。     

试论反应性抑郁形成的心理过程

对反应性抑郁形成的心理过程进行解释的理论中 ,较有影响的有精神分析理论、控制理论、认知理论、自我注意理论和行为主义理论。由于这些理论都仅强调某一个因素的作用 ,因而有一定的局限性。如果综合考虑这些因素 ,同时还考虑到评价、个体扮演角色的多少及其采用的应付方式等因素的作用 ,就可以看出反应性抑郁形成的完整心理过程。     

Light and dark adaptation of visually perceived eye level controlled by visual pitch

The pitch of a visual field systematically influences the elevation at which a monocularly viewing subject sets a target so as to appear at visually perceived eye level (VPEL). The deviation of the setting from true eye level averages approximately 0.6 times the angle of pitch while viewing a fully illuminated complexly structured visual field and is only slightly less with one or two pitched-from-vertical lines in a dark field (Matin & Li, 1994a). The deviation of VPEL from baseline following 20 min of dark adaptation reaches its full value less than 1 min after the onset of illumination of the pitched visual field and decays exponentially in darkness following 5 min of exposure to visual pitch, either 30° topbackward or 20° topforward. The magnitude of the VPEL deviation measured with the dark-adapted right eye following left-eye exposure to pitch was 85% of the deviation that followed pitch exposure of the right eye itself. Time constants for VPEL decay to the dark baseline were the same for same-eye and cross-adaptation conditions and averaged about 4 min. The time constants for decay during dark adaptation were somewhat smaller, and the change during dark adaptation extended over a 16% smaller range following the viewing of the dim two-line pitched-from-vertical stimulus than following the viewing of the complex field. The temporal course of light and dark adaptation of VPEL is virtually identical to the course of light and dark adaptation of the scotopic luminance threshold following exposure to the same luminance. We suggest that, following rod stimulation along particular retinal orientations by portions of the pitched visual field, the storage of the adaptation process resides in the retinogeniculate system and is manifested in the focal system as a change in luminance threshold and in the ambient system as a change in VPEL. The linear model previously developed to account for VPEL, which was based on the interaction of influences from the pitched visual field and extraretinal influences from the body-referenced mechanism, was employed to incorporate the effects of adaptation. Connections between VPEL adaptation and other cases of perceptual adaptation of visual direction are described.     

小规模群体开放式与封闭式讨论任务的工作特性比较

１４个小组的大学生共６８人参加两种不同的群体工作,其中７组进行开放式问题的讨论,７组进行封闭式问题的讨论。从工作进程、工作模式和工作特点等方面记录群体工作行为：工作进程各阶段所用时间,发言的针对性,发言的连续性,说明问题的方式和深度,群体的意见分歧与支持行为和表达方式。结果表明：封闭式问题需要更多的时间澄清问题并且更多引用例子来阐述观点;讨论开放式问题多采用归纳推理而封闭式问题多采用演绎推理;无论在哪种问题的讨论中,针对个体的发言都显著多于针对整体的发言,而且人们更多地以非言语的方式而不是口头方式表示赞成。本文对以上结果在电视、电话和计算机辅助会议系统设计中的应用作了进一步讨论     

The effects of grammatic class and cue type on cueing responsiveness in aphasia

This study investigated the effects of two types of cues (semantic and phonemic) and two grammatic classes (noun and verb) on cueing responsiveness. Subjects consisted of 10 Broca's, 10 Wernicke's, 8 conduction, and 8 anomic aphasics. Cues were administered following failure to name on confrontation. Responsiveness to the two types of cues was dependent on aphasic type and grammatic class. Broca's and conduction aphasics responded better to phonemic cueing, while anomic aphasics were more responsive to semantic cueing. With regard to grammatic class, aphasics responded better to phonemic cueing on nouns; however, no significant difference between types of cues was demonstrated on verbs. Neuropsychological implications for the cueing and naming processes are discussed.     

聋哑儿童与正常儿童镜像书写的比较

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。     

六个月至三岁儿童用左右手抓物的实验研究

对300名6个月至3岁的儿童进行了抓物的实验。发现1岁以内儿童的左、右手率在50％上下,随年龄增长,右手率逐渐增加:1—1(1/2)岁为69.4％,1(1/2)—2岁为71.3％,2—2(1/2)岁为76.9％,2(1/2)—3岁为81.5％。男、女存在差异,男孩右手率较女孩高。实验中出现双手抓物现象,但1岁半后此现象迅速减少。父母双方或一方为左利者,其孩子的左手率比那些父母为右利者高。此外,孩子抓物时对不同颜色物品和玩具则呈现选择性倾向。
