石杉碱甲对动物行为和脑皮层电图的影响

石杉碱甲是我国首先从石杉科植物中提取出的一种新生物碱。它是胆碱酯酶抑制剂,它的作用和毒扁豆碱相似,但其毒性较小。本文观察了石杉碱甲对大鼠暗回避反应和家兔脑皮层电图的影响。其主要结果如下: 1 石杉碱甲可对抗东莨菪碱所致的记忆障碍,主要表现为石杉碱甲可使动物进入暗箱的潜伏期延长,并使暗回避反应的错误次数明显减少。 2.石杉碱甲能使家兔皮层区的脑电波均持续出现低振幅快波,并使海马区出现持续的且有规则的θ节律。脑皮层电图的结果表明,石杉碱甲和东莨菪碱相互不但有颉顽作用,而且,进一步证实了石杉碱甲对东莨菪碱的颉顽主要是通过中枢作用来调制的。     

Mao Tsetung thought since the cultural revolution

In all respects, Mao has succeeded in creatively developing Marxism in such a way that Mao thought seems adequate to the Chinese situation and superior to the Soviet version.This article is drawn from the writer's forthcoming bookMao Tsetung Thought and the International Communist Movement to be published by the Research Institute on the Sino-Soviet Bloc, Chestnut Hill, Massachusetts. The preparation of this article and related studies was supported by a grant from the American Council of Learned Societies and the American Philosophical Society.     

尿儿茶酚胺的高效液相色谱分析——电化学检测法

本文报道了尿去甲肾上腺素、肾上腺素和多巴胺的高效液相色谱分析电化学检测法。用Bio—Rex阳离子树脂处理提取尿中的儿茶酚胺。该法的回收率去甲肾上腺素为97±5％;肾上腺素为97±9％;多巴胺为76±8％(各进行5次测定)。本文同时对不同生理心理状态下尿儿茶酚胺的分泌量进行了液相色谱法测定。     

铁钦纳的存在主义

铁钦纳(E.B.Titchener 1867—1927)自称他的心理学为存在主义的。铁钦纳把他的心理学与当时美国的机能主义心理学相对立。西方心理学界一般称铁钦纳的心理学为构造主义。 铁钦纳认为心理学的问题,如其他自然科学一样,是:什么?怎样?和为什么?三个问题。心理学的什么,是将心理现象分析为它的元素;心理学的怎样,是寻求这些元素如何互相联系的规律;心理学的为什么,是以一个心理过程相应的神经过程来解释这     

实验动物的处死方法与脑内单膜类神经介质变化的关系

中枢神经介质的研究虽然只有短短二十多年的历史,但它与痛觉、情绪、睡眠与觉醒、学习和记忆有密切关系,特别是神经介质在精神活动中所起的作用引起了人们的浓厚兴趣。这已成为心理学研究领域内不可忽视的重要课题,它为脑功能的深入研究开辟了新的前景。     

Different differences: revelation and disclosure of social identity in the psychoanalytic situation

The authors propose a taxonomy of social identities, suggesting that three different classifications of identities can be distinguished. These comprise those that are innate and visible, such as race or gender; those that are innate, but invisible, such as sexual orientation; and those that are acquired or achieved, such as marital status or political affiliation. The authors argue that each of these categories has different implications for the revelation or disclosure of aspects of the therapist's identity, as well as for transference-countertransference dynamics. These points are illustrated with brief clinical examples.     

Lexicality and phonological similarity: a challenge for the retrieval-based account of serial recall?

The retrieval-based account of serial recall (Saint-Aubin & Poirier, 2000) attributes lexicality, phonological similarity, and articulatory suppression effects to a process where long-term representations are used to reconstruct degraded phonological traces. Two experiments tested this assumption by manipulating these factors in the recall of four- and five-item lists of words and non-words. Lexicality enhanced item recall (IR), but only affected position accuracy (PA) for five-item lists under suppression. Phonological similarity influenced both words and non-words, and produced impaired PA in silent and suppressed conditions. Consistent with the retrieval-based account, words and non-words of high word-likeness appear subject to redintegration. However, some findings, like suppression not reducing the phonological similarity impairment in suppressed conditions, present challenges for the retrieval-based account and other models of serial recall.     

启动效应与技能学习相互关系的实验研究

利用字母光点和追踪旋转任务,分别对３１名和３２名大学生进行启动和技能学习相互关系的研究。结果发现：在两种任务内,被试的启动和技能学习存在相互独立的关系;在追踪旋转任务中,练习的频率对启动和技能学习都会产生影响。     

The overjustification effect: A meta-analysis

This article reports the results of a meta-analysis using 50 experimental studies (256 effect sizes) of the overjustification effect. In general, we found support for the effect across age, dependent measure, and design type in specific situations where it is predicted to occur. Findings are less supportive of the theory for situations where there should be no difference between experimental and control groups (e. g. non-contingent or unexpected reward). Suggestions for future research are made.     

The development of a short Money Ethic Scale: Attitudes toward money and pay satisfaction revisited

In order to measure people's attitudes toward money, a 12-item Money Ethic Scale (MES) was developed based on a sample of 740 subjects. Three factors were identified: Success, Budget, and Evil. Attitudes toward money as related to people's demographic variables, personality variables, and job satisfaction were examined. Those who scored high on the Money Ethic Scale (the overall Money score) tended to have high economic values, low religious values, high Type A behavior pattern, to be older, to have low pay satisfaction, and high political values. Implications related to compensation management are discussed.
