一日龄小鸡的记忆保持及其与脑内加压素（AVP）含量的相关研究

以一日龄小鸡为实验对象,进行一次性厌恶回避反应训练,并应用加压素的放射免疫测定法,分析比较记忆保持测验中,成绩优、劣及对照组动物与其脑内加压素含量的相关。实验结果表明,记忆保持良好的动物,脑内加压素含量明显低于对照组和记忆不良组,而记忆不良组与对照组之间则无明显差异。提示在正常生理状态下,加压素参与记忆过程的调制,并可能在这一过程中有一定的耗竭或合成减少,如适时得以补充,则对记忆的巩固和再现起易化作用。

Marxism and Christianity within the great wall

Chinese culture has remained steady, stretching through time as long and unbroken as the Great Wall. In thousands of years, Chinese culture has exhibited a remarkable ability to assimilate foreign intrusions. Even though several times throughout Chinese history minority nationalities have been in military and political control of China, they were gradually assimilated by Chinese culture. Christianity has spent more than a thousand years attempting to convert the Chinese with only negligible success. However, why was Marxism able to become the dominant ideology in only 30 years? This article discusses the critical cultural roots of the different destinies of Marxism and Christianity within the Great Wall.     

照度变化对视觉辨认的影响

前 言 近年来,关于工业企业和民用照明视觉功能的探讨逐渐多起来,这方面的研究对于制定照度标准和保护视力有着现实意义。我国过去的研究虽获得不少有益结果,但大多是在一般照明环境中、照度一般在几百勒克斯以下,以阅读视力表作为视觉功能指标。本研究是在比较严格控制的近似等效球照度的实验条件下,在1.7-2160Lux照度范围内,控制观察时间,探讨照度变化对视觉辨认的影响。此外,我们还研究了两种背景(亮和暗)对视觉辨认的影响。     

20—36.5米氮氧饱和及50-70米空气巡回潜水模拟实验的神经和心理功能研究

人体呼吸高分压氮气时会发生麻醉现象,出现欣快、动作不协调、判断迟钝等。氮分压愈高,症状愈明显。Bennett等在30米空气暴露时定量地测到有效行为的障碍。Elcombe等在4个绝对压含5.2％氧的氮氧混合气饱和暴露时,也观察到智力和行为的     

关于闪光盲的研究——Ⅱ 短暂强闪光对中心视觉恢复时间的影响

在暗适应条件下对11名正常视力的男性受试者测定了进入眼内的闪光能量与恢复时间的关系。当闪光时间为0.1—5毫秒,积分亮度为0.07—1.69熙提秒时,人眼辨别一6’视角的蓝道环缺口所需的恢复时间仅取决于亮度和曝光时间的乘积,即Bloch律成立。文章并对防闪光盲护目镜应具的关闭时间进行了讨论。     

评西方心理学辩证理论研究方向中的若干问题

《美国心理学家》杂志1976年第10期上刊载了里格尔的一篇“辩证法心理学宣言”(下简称“宣言”)。这是继苏联科尔尼洛夫的“辩证唯物论心理学”发表半个世纪以来西方心理学理论界的一个新动向,是值得认真对待的动向。从三十年代开始,尤其是七十年     

Factors influencing school achievement of children from low socioeconomic groups in Malaysia(1)

A general model is proposed relating the social and nutritional factors involved in school performance of children from poor socio-economic backgrounds. The model has been tested in a group of 263 primary school children who came from mainly lower-class families in Malaysia. School performance was assessed by the mark in a national school examination; the factors considered were race, sex, type of school attended, nutritional status and score in the Goodenough-Harris Draw-a-Man test, and also the family size, income and education of parents. Multiple linear regression and extended median test were used in the analysis. There were strong associations between poor school performance on the one hand and nutritional and socio-economic conditions on the other. However, detailed analysis showed that, for most sub-groups, nutritional status was not a direct causal factor in school performance. Both nutrition and school achievement reflected home circumstances, particularly family income. There were however significant differences among children of different races. Many of the pathways on the general model have been shown to be irrelevant in this group of children; those pathways which remain are likely to be causal. The Goodenough-Harris test showed highly significant differences between children of different ethnic groups. The general model seems justified as a framework for investigating school performance. It has been shown that simple correlation between factors is not a good guide to cause-and-effect relationships. Each deprived group is likely to have its own significant pathways, so that each group should be analysed rather than applying generalisations derived from other populations.     

Detecting phonemes and letters in text: Interactions between different types and levels of processes

In six experiments, subjects detected phonemes or letters in text presented auditorily or visually. Experiments 1 and 2 provided support for the hypothesis that a mismatch between the phoneme and letter representations of a target leads to detection errors. In addition, visual word unitization processes were implicated. Experiments 3 and 4 provided support for the hypothesis that the Gestalt goodness of pattern affected detection errors when subjects searched for letters. Experiments 5 and 6 demonstrated that the effects of unitization on the detection of letters in common words were decreased by altering the familiar configuration of the test words. The combined results of all six experiments lead to the conclusion that both visual and phonetic processes influence letter detection, that these processes communicate through a type of cross-checking, and that there are at least two levels of visual (and perhaps of phonetic) processing involved in the letter detection task.     

识认熟悉者照片时视觉事件相关电位的研究

50名受试者接受视觉事件相关电位检查,熟人照片作靶刺激,生人照片为对照刺激,二者的概率均是0.25,其余不同陌生人之照片作非靶刺激,其概率为0.75。全部照片以随机次序用幻灯机投映,受试者在看到照片时立即按压“YES”键或“NO”键作为是否认识照片中人物的反应。同时分别于Cz点和Pz点记录和叠加视觉事件相关电位。以Cz点和Pz点的P3之波幅和波面积共四项数据为指标,若熟悉者照片作靶刺激四项指标中三项以上大于对照陌生人照片时判定阳性。受试者中49名(98％)获阳性结果,判定这些受试者“认识”该照片中的人物。
