人的高级神经活动的年龄特点

生理学中已经积累了不少事实材料,可以说明人脑活动的年龄发育和退化的特征。但是,对某些时期,例如,对出生到7岁以及50岁之后的时期,进行了系统地研究,而对其它年龄期,只是作了些个别的研究工作。对高级神经活动生理学主要问题的研究也不平衡;对儿童第一信号系统水平上的条件反射活动形成的规律,研究得很充分,在这方面进行研究的有等人;对第二信号系统的发育和机能活动机制的研究却比较少,对确定儿童类型特点以及在理论和实践上都很重要的许多其它问题,研究得也不充分。因此,本文中材料的安排也相应地不平衡。     

苏联教育科学院普通和教育心理学研究所科学活动的总结和展望

苏联教育科学院普通和教育心理学研究所是我国最早的心理学研究机构之一。1982年是这个研究所成立七十周年。关于它的历史,它在发展俄国和苏联心理科学中的作用,这个所的著名科学家在这门科学中所做的贡献,已有许多著作阐述。本文专门谈这个研究所的科学活动的一般总结和展望(文中所用材料是由这个所的主要研究人员提供的)。     

起源及综合

在这篇文章中,我们讨论比较心理学史的一些情况,并阐述比较心理学及社会生物学之间一个特殊的接触点,它可作为把这两门以及有关学科整合起来的焦点。我们探索的思路是     

Attribution of control and teenage pregnancy

In rural Appalachia in Tennessee, data on 13 female adolescents who had experienced a pregnancy (mean age=16 years, 7 months) were compared with those on 38 female adolescents who had not experienced a pregnancy (mean age-16 years, 4 months) to test the hypothesis that teenagers who experience a pregnancy have external attributions of control over their life events. The Nowicki-Strickland Locus of Control Scale for Children was administered to determine their beliefs about causes of events in their lives. All the girls were white and matched for socioeconomic status, housing, and cultural background. The mean attribution of control to external agents score stood at 14.5 for girls who had experienced a pregnancy compared with 12.7 for those who had not experienced a pregnancy, but the difference was not significant (p=.08).54% of the cases exhibited external attributional orientation compared with 16% of the controls (p.02). This finding concurred with that of earlier studies. The fact that not all the girls who had experienced a pregnancy had external attributional orientation suggested that it is not the only factor linked to adolescent pregnancy. Studies have not identified whether external attributional orientation is a causal factor or consequence of adolescent pregnancy. A 1980 study found that women who had shown more external locus of control scores during pregnancy and tended to castigate themselves had a high probability of postpartum depression. Another study indicated that rises in depression among adolescents were linked to prechange orientations toward external attributions of control. Practitioners should selectively pay attention to teenagers who have extreme attributional orientations since many teenagers carry their pregnancies to term and choose to rear their infants. These orientations appear to pose risks for the adolescent mother and her children.     

A behavioral perspective on college teaching

Much of the subject matter learned in college, particularly during the first two years, is taught in relatively large classes with text and lecture as the primary source of the information being learned. If students make effective and prolonged contact with these sources, they can acquire extensive verbal repertoires in many areas of knowledge. Unfortunately there are many other activities that compete for the typical student's study time. Several factors are often cited as variables that will support study behavior in competition with other activities, but the only powerful one available to the teacher is the exam grade, as it is related to the course grade. However, unless exams are clearly related to appropriate study behavior, require through and extensive coverage of the subject matter, occur frequently (preferably no less often than once a week), and are also clearly related to the course grade, even this factor will not generate prolonged and effective study behavior. Effective college teaching is essentially a form of aversive control, but if done properly the aversiveness is quite mild, and such aversive control can be responsible for the development of large and valuable intellectual repertoires.     

语言消亡的原因和环境

绪论大家知道,世界上存在或者说存在过5000多种语言,但其中数百种已不再有任何个人或者语言社团使用。这些语言中的某些语言,诸如拉丁语,古希腊语和斯拉冯语等,维持着奄奄一息的生命,犹如供人瞻仰的古迹,今天尚能发挥的作用极为微弱,仅限于专业研究;其余大多数语言只对一小群语言学家、历史学家和把目光转向过去的其他专家有用。许多语言已了无生     

Japan's dilemma with the definition of death

Japan is unusual among industrialized countries in its reluctance to use brain criteria to determine death and harvest transplant organs. This results from public distrust of the medical profession due to an earlier incident, and from concern that technological interventions will threaten religious and cultural traditions surrounding death and dying. Public acceptance is growing, however, as medical professional groups and universities develop brain criteria, and as pressure from patients who could benefit from a transplant, as well as from foreign countries, increases.     

世界的可知性原理

对一切生物所固有的辨识能力所做的最新研究证明,辨识能力不仅体现生物机体在直接周围环境中量的规定性,而且体现质的规定性。例如,植物借助根系“选择”土壤中含有的其生命活动所必须的物质,吸收数量上刚好是它需要的物质。这种选择借以实现的“指示器”,吸收植物所需营养物的根系感受体,完全不同于动物的感觉。植物的根系起着一个进行生物化学过程的器官的作用。可是认识,特别是人的感官的作用,难道不含有使来自外部世界的信息传到人脑的一定生物化学过程吗?这一例证中最重要的是对被感受的外部作用能够进行辨     

科学革命的几个阶段

过去的10年中,科学史家和科学哲学家掀起了一场对科学革命或科学进步的方式进行各种各样分析的热潮。在此期间出版的大量文献中,很多都对这些分析中的这种或那种分析内在的一致性、广泛的适用性或普遍的应用等问题进行了一系列的论证,争论的主要部分集中在T.S.库恩的思想上。库恩的论述很独特,它们都是以“范式”这个概念为基础的。所谓范式,就是一组共有的方法、标准、解释方式或理论,或者说是一种共有的知识体。在库恩看来,所谓科学中的革命,就是这样的一种范式向另外一种范式的转换,他认为,科学形势
