Aggression in toddlers: associations with parenting and marital relations.

This study examined the relation among parenting factors, marital relations, and toddler aggression. A structured questionnaire was administered to both parents of 254 2-year-olds. The authors used correlation and hierarchical multiple regression analyses to assess the extent to which certain personality traits, drug use, parenting style, and marital conflicts were related to the toddlers' aggressive behavior. Results showed that the maternal child-rearing and parental aggression domains had a direct effect on toddler aggression. The domain of maternal child rearing also served as a mediator for the domains of marital relations, paternal child rearing, parental aggression, and parental drug use. The findings indicated that maternal child-rearing practices, personality attributes, and drug use were more important than paternal attributes in relation to toddler aggression. Implications for prevention among families at risk are discussed.     

新疆维吾尔、哈萨克、回族519名男青年试用EPQ问卷的初步报告

本文报告以维吾尔(简称维)、哈萨克(简称哈)、汉语EPQ问卷对新疆维、哈、回族519名16～29岁男青年的测查结果。表明EPQ各量表间相关情况和总趋势与英国、龚氏常模相似,P量表分均为最低;L量表分与龚氏常模一样均为最高。维、哈族个性特征显著外倾,尤以哈族突出。提出民族的历史发展、社会文化传统、劳动生活方式等因素是形成维、哈族个性特征的基础,认为龚氏常模及其划界分需进一步修订和完善。     

具体认知和抽象认知与社会文化因素的关系

采用认知测试、查阅人类学资料、现场调查和谈话等多种方法,探讨了我国不同生产方式、不同地区和不同民族４６０名成人的具体认知、抽象认知和认知方式及其与生态文化因素的关系。研究结果基本支持了我们理论上所假设的社会文化因素与具体认知操作、抽象认知操作、认知方式的关系,即狩猎和城市社会的生态环境和生产方式对人施加一种生态压力,增进其个体的具体的和抽象的认知,促使其抽象型认知方式的形成;而在捕鱼、游牧和农耕社会的生态环境和生产方式的作用下,个体倾向于较低水平的具体和抽象认知操作以及具体型的认知方式。紧密的社会结构和强调服从的社会化过程,与其个体较低水平的具体和抽象认知及具体型的认知方式相关联;而松散的社会结构和强调自主性的社会化过程,与较高水平具体和抽象认知操作、抽象型的认知方式相联系。正规教育等现代化因素是促进人认知,特别是抽象认知的有力因素。     

罪犯改造成效评估量表的建构

本研究运用因素分析法,尝试建构我国监狱中罪犯改造成效评估量走。该量表分Ａ版（干警评定量表）与Ｂ版（服刑人员他评量表）。结果表明,该量表具有较高的信度、效度,所得的改造成效评估三因素结构合理,内容清晰     

双眼立体视觉的信息加工Ⅰ.视差和空间频谱的关系

本文分三部分;也是三个步骤: Ⅰ.根据视差用计算机产生立体图对; Ⅱ.立体图对的空间频谱; Ⅲ.视差和空间频谱的关系。 得到一些结果: 1.具有视差的立体图对的空间频谱高峰有相对的位移。 2.移动的偏向和三维物体离观察者的远近有关,如果是一个单调变化的物体,则离人近的一侧频谱高峰向高频方向移,离人远的一侧向低频方向移。 3.移动的多少是和三维物体的平均深度变化率有关,变化率愈大移得愈多。 4.高峰的峰值则和三维物体的绝对深度有关。     

Influence of the large–small split effect on strategy choice in complex subtraction

Two main theories have been used to explain the arithmetic split effect: decision‐making process theory and strategy choice theory. Using the inequality paradigm, previous studies have confirmed that individuals tend to adopt a plausibility‐checking strategy and a whole‐calculation strategy to solve large and small split problems in complex addition arithmetic, respectively. This supports strategy choice theory, but it is unknown whether this theory also explains performance in solving different split problems in complex subtraction arithmetic. This study used small, intermediate and large split sizes, with each split condition being further divided into problems requiring and not requiring borrowing. The reaction times (RTs) for large and intermediate splits were significantly shorter than those for small splits, while accuracy was significantly higher for large and middle splits than for small splits, reflecting no speed–accuracy trade‐off. Further, RTs and accuracy differed significantly between the borrow and no‐borrow conditions only for small splits. This study indicates that strategy choice theory is suitable to explain the split effect in complex subtraction arithmetic. That is, individuals tend to choose the plausibility‐checking strategy or the whole‐calculation strategy according to the split size.     

建构主义教学与元思维的关系:认知压力的解释

本研究采用建构主义教学评估问卷、认知压力问卷、一般元思维量表与情境元思维量表对381名学生进行测量,考察了建构主义教学与元思维之间的关系,以及一级、二级认知压力在其中的中介或解释作用。研究采用结构方程模型分析,结果显示:(1)仅考虑一级认知压力时,建构主义教学能正向预测两种元思维,一级认知压力在建构主义教学与两种元思维间皆起部分中介作用;(2)仅考虑二级认知压力时,其在建构主义教学与两种元思维间皆起完全中介作用;(3)同时加入两种认知压力时,仅二级认知压力的中介作用显著。
