同伴关系与社会行为：社会测量学分类方法在中国儿童中的适用性研究

本研究应用科威和道吉（１９８３）的社会测量学分类方法,对具有不同同伴关系的儿童的行为特征进行了考察、结果表明,与西方心理学文献一致,受欢迎儿童具有较强的社会能力和积极的行为品质,被拒绝儿童倾向于具有攻击性、破坏性和学习困难。此外,被忽略儿童容易表现羞怯与焦虑行为,缺乏同伴之间的亲密感,而有争议儿童则具有积极和消极行为品质“两重性”。这一研究提供了社会测量学分类方法在中国文化中的有效性的初步证据。     

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。     

EFFECTS OF CULTURES AND LANGUAGES ON SELF CONCEPTIONS*

Cultural evolution in self conceptions under the influence of external cultures was explored through semantic differential ratings of Turkish English-speaking (TK/EN) students. As the criterion for inter-cultural and inter-language comparisons, the “norm” conceptions were obtained from two indigenous samples that represent the American/English (AM/EN) culture and the Turkey/Turkish (TK/TK) culture respectively. Results indicated significant transfusion effects of the “providing” (AM/EN) culture on self conceptions of the “receiving” (TK/EN) culture - in desaturating as well as elevating the semantic intensities of various aspects of self identity over the “native” (TK/TK) culture. An implication was made that future cross-cultural interactions should become an effective mutual learning process for improving inter-cultural and inter-group heterogeneities and conflicts, rather than for spliting a homogeneous indigenous culture into many fragmented and isolated entities.     

Grading distractor-identification tests

On distractor-identification tests students mark as many distractors as possible on each test item. A grading scale is developed for this type testing. The scale is optimal in that it is the unique scale giving an unbiased estimate of the student's true score, i.e., the score that would result if no guessing occurred. If the test is administered as a usual multiple choice test and graded using the usual correction for guessing scale, the expected item score is the same as for the distractor-identification testing using the optimal grading scale. However, the variance of the item score is shown to be less for distractor-identification testing than for usual multiple choice testing under certain conditions.     

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.     

Factors Influencing Gay Men's Attitudes,Subjective Norms,and Intentions With Respect to Performing Sexual Behaviors1

In a recent paper (Fishbein et al., 1992) gay men's attitudes and subjective norms were found to be accurate predictors of their intentions to perform a variety of sexual behaviors. In addition, the relative importance of norms as determinants of intention was found to be greater in Seattle (a city with a well organized gay community) than in Albany (a city in which the gay community is not well organized). The purpose of the present study was to investigate the extent to which the men's attitudes, subjective norms, and intentions were influenced by a number of situational and individual difference variables. Three hundred and fourteen self-identified gay or bisexual men from Seattle (134), Denver (78), and Albany (102) completed a questionnaire specifically designed for this study. As expected, type of partner and type of sexual activity significantly influenced attitudes, perceived norms, and intentions. In addition, these dependent variables were also influenced, in part, by city of residence, age, and perceived risk of HIV infection. The findings provide additional justification for developing different interventions for gay men in different cities, age, and perceived risk groups.     

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。
