Dimensionality and validity of two scales measuring different aspects of self-esteem

Two self-esteem (SE) scales aimed to measure self-esteem–conceptualized primarily (a) as the individual's ego-integrated libidinous and aggressive drives and their derivatives (Basic SE), and (b) as the need to earn self-esteem by competence and others' appraisal (Earning SE)–were developed and factor analysed. In order to construct- and cross-validate the scales, they were related to other well-known personality scales as well as to a projective technique (TAT) in two independent samples of first semester psychology students ( n = 153, n = 82). The empirical factor structure coincided well with the theoretical formulations. Basic SE showed concurrent validity being highly correlated ( p < 0.001) with both Rosenberg's and Coopersmith's self-esteem scales and highly or moderately with Neuroticism, Extraversion (EPQ) and Test-Anxicty (TAS) in both samples. Earning SE gained some construct validation by its relation to Type-A scores (JAS) as well as to verbal fantasy stories on TAT-pictures measuring Need of Achievement.     

The problem: American education the solution: Use behavior analytic technology

In spite of numerous demonstrations that America's youth can be effectively educated with behavior analytic teaching techniques, few of the country's children are benefiting from the technology. In addition scholarly reviews of effective teaching strategies have often omitted reference to behavior analysis. One way to look at this problem is as a two-step operation. First, it is necessary to determine procedures that work; second it is necessary to devise strategies for effective dissemination. The present issue of JOBE (Vol. 1, No. 3, Sept. 1991) contains the recommendations of six outstanding behavioral educators as to how to deal with the dissemination problem. The initial article by Pumroy and McIntire describes the activities of an organization which trains school psychologists and teachers to use behavioral procedures and advocates for the techniques with a number of audiences. Next, Engelmann suggests that the public have more control over school activities and that legal action be taken against irresponsible administrative decisions. Hall advocates for less labor-intensive procedures and the sale of curricular materials based on behavioral principles. Binder proposes that dissemination of the technology become a private endeavor that responds to consumer needs. Rosenfield describes a collaborative model of consultation that increases treatment adherence. Finally, Albers and Greer describe research that isolates a key teacher behavior that results in greater academic proficiency.     

Dualism and its Importance for Medicine

Cartesian dualism has been viewed by medical theorists to be oneof the chief causes of a reductionist/mechanistic treatment ofthe patient. Although I aver that Cartesian dualism is one culprit for the misapprehension of the genuine treatment of patients in termsof both mind and body, I argue that interactive dualism whichstresses the interaction of mind and body is essential to treatpatients with dignity and compassion. Thus, adequate medical carethat is humanistic in nature is difficult (if not impossible)to achieve without physicians adhering to a dualistic frameworkin which the body and person is treated during illness.     

Interactions of persistent slip bands with a grain boundary on the common primary slip plane in a copper bicrystal

In this letter, the dislocation patterns on the common primary slip plane in a fatigued \[1-34]-\[182-7] copper bicrystal with a Sigma=19b grain boundary (GB) have been investigated using the electron channelling contrast technique in a scanning electron microscope. The results show that the two-phase dislocation structure, such as veins and persistent slip band (PSB) walls, embedded within veins, can be clearly seen on the common primary slip plane. In particular, the interactions of PSBs with the GB are clearly revealed. It is found that there are three kinds of interaction mode between the GB and the dislocations during cyclic deformation, and those are discussed. It is suggested that the dislocations carried by PSBs cannot transfer through the GB continuously even though the bicrystal has a common primary slip plane and its surface slip bands are continuous across the GB.     

工作记忆训练在精神疾病中的应用

随着工作记忆缺损与各类精神疾病的关联被逐渐阐明,研究者开始关注工作记忆训练能否作为干预手段应用在精神疾病领域中。当前,在对ADHD、精神分裂症、抑郁、焦虑、成瘾障碍和自闭症患者进行的工作记忆训练中发现了训练近迁移、远迁移以及临床症状缓解的相应证据,以及直接(通过提升工作记忆能力起效)和间接(通过提升其他关联能力起效)两条效益路径。此外,一个针对精神疾病患者的有效训练范式应当就三个层面进行考察:训练的一般成分(即受训的核心加工过程),训练的疾病特异成分(例如情绪工作记忆训练);以及训练的辅助性成分(例如动机、策略、慢波睡眠等)。未来研究需要关注适用不同精神疾病的训练范式与程序,促进工作记忆训练的定制化,并且通过完善评估手段进一步澄清工作记忆训练在病患中的效益机制。

多维Rasch模型在维度分数报告中的应用—对带宽-保真度困境的解决

分别采用四维度和十五维度Rasch模型分析包含项目内多维度结构的科学测验数据,估计两种维度结构下维度分数的信度.结果表明,对比相应的单维模型而言,四维度与十五维度Rasch模型均能够极大提高各内容维度上分数估计的信度.四维度与十五维度Rasch模型拟合结果的比较表明,对于总长度固定的测验,维度数目的增加能够补偿子维度长度减少引起的信度损失.但是这一作用必须以维度间较高的相关性为前提.     

策略型学习者认知心理结构及其运行机制

高效率学习是现代社会发展的需要,也是适应信息量急增的社会变革需要的必然选择。从教育心理学的视角研究策略型学习者,对其高效率学习心理,特别是高效率学习认知心理结构及其运行机制进行研究,有助于教育理论与实践工作者准确把握这类特殊教育对象的心理特点与规律,为开展策略型学习者教育提供了心理学依据。     

不同卷入度人群的组织公平结构

以国家助学金分配为背景,选取755名大学生为被试,运用量表测量和验证性因素分析办法考察不同卷入度人群的组织公平维度结构.结果表明:不同卷入程度个体的组织公平维度不一致.卷入程度低和卷入程度高但同时作为分配者的个体的组织公平是三因素结构.卷入程度高且只作为接受分配者的组织公平是四因素结构.同时,指出了信息公平在组织公平中具有重要的作用.
