3—6岁白、哈尼族与汉族儿童的颜色命名能力的发展

探讨了云南地区白族与哈尼族３—６岁儿童的颜色命名能力发展,并与北京地区汉族同龄儿童作了比较。实验结果表明,不同民族的儿童的颜色命名能力都伴随年龄增长而逐步提高;但汉族儿童的颜色命名能力发展略高于哈尼族与白族同龄儿童。总的来看,儿童对不同颜色正确命名能力的发展有着共同的规律性,即黑、白、红三色较易正确命名,其次是黄、绿、蓝三色较难正确命名,命名正确率最低的颜色是橙与紫。     

智力落后儿童人格特性的研究

智力落后儿童由于大脑功能发育障碍,在个性的成熟和发展方面受到一定限制,表现出与正常儿童不同的个性特征。在不同智残程度的儿童中也存在着个性差异。智力与个性发展有密切关系,脑功能受损越严重,对个性发展的影响也就越明显。     

心血管病人的心身反应特点的研究——Ⅱ.对冠心病人的行为类型特征的探讨

关于冠心病人的性格或行为类型特征的研究,在我国已开始引起重视。本研究从全国18个省市测查了了14名冠心病人,425名常人(非冠心病人)和220名病人家属的评定。发现冠心病人中A型行为类型问卷的得分明显地高于常人,差异显著(P<0.01);冠心病人中A型人分布所占比例大大高于常人,相差2.2倍。无论是常人组还是病人组在不同性别和不同年龄组之间都没有明显差异(P>0.05)。在病人中脑力劳动者得分比体力劳动者高(P<0.05)。病人的自我评定和亲属评定之间的等级相关以及常人和病人先后两次重复测试之间的等级相关均为正相关(r值均超过0.50),表明我们所编制的A型行为类型问卷是可用的。     

Reinforcing effects of prerecorded words and delayed speech feedback on the verbal behavior of a neologistic schizophrenic

The possibility of using prerecorded words and 2-sec. delayed speech feedback as reinforcement in the reconditioning of intelligible verbal responses in a chronic, neologistic schizophrenic patient was investigated. A test situation was devised which involved daily presentation of 100 stimulus word-picture cards to elicit verbal responses. The results indicated that both singly presented prerecorded words and delayed speech feedback apparently strengthened correct and intelligible verbal responding.     

A method for simulating non-normal distributions

A method of introducing a controlled degree of skew and kurtosis for Monte Carlo studies was derived. The form of such a transformation on normal deviates [X N(0, 1)] isY =a +bX +cX ² +dX ³. Analytic and empirical validation of the method is demonstrated.This work was done while the author was at the University of Illinois at Champaign-Urbana.     

Multiple anchoring of category rating scales

A psychophysical experiment compared the effects of two different kinds of anchoring upon category ratings of the sizes of squares: (1) single anchoring in which the same square was presented on every anchoring trial, and (2) multiple anchoring in which squares of different sizes were presented on anchoring trials. Subjects did not rate the anchors, only those squares presented on alternate trials as the series stimuli. The major finding was that the two kinds of anchoring have similar effects. As with the single anchor, the multiple anchor establishes a new endpoint for the scale of judgment. The previously demonstrated relationship of increasing and then decreasing contrast as a function of the remoteness of the single anchor (Sarris, 1967, 1976) was found also for multiple anchoring.     

The relative effectiveness of alternative job sources

Vocational research has focused on the occupational choice process and the individual's adjustment to work. Very little research has examined the job search process in which the individual must engage in order to implement occupational choices. This study examines one dimension of the job search process: the relationship between job source and subsequent work experiences. The data reveal that when the respondents initially entered the labor market, those relying on formal job sources tended to work in higher-level occupations and in jobs more closely related to their training than their counterparts who used other job sources. In the longer run, the labor market advantages associated with the use of formal job sources dissipated for the engineering majors but tended to persist for the business alumni.     

妄想型与非妄想型精神分裂症唤醒水平(皮肤电反应)的初步探讨

问 题 机体如果连续处于高唤醒水平,就会出现中枢神经系统兴奋-抑制关系紊乱的现象。一般的后果是抑制机制受损害而产生中枢性调节障碍(Malmo 1959)。在行为上,唤醒水平表现为机体作出反应、准备行动的能量动员水平。对精神病人唤醒水平的研究     

初中代数“有理数”程序教学实验研究

本研究对程序教学与传统教学的效果作了对比。研究表明,程序教学可以缩短学习时间、提高学习效果、激发学习动机,有助于自学能力的培养。如果程序教材能够符合学生的认识规律,在教材中尽量增加启发因素,那么程序教学对于思惟能力的培养也可以起到积极的作用。
