Methodological and theoretical issues in neuropsychological assessment

While there are philosophical and theoretical differences between neuropsychologists and behavior therapists, it is suggested that a significant reconciliation can be achieved in regard to assessment and treatment of the brain-damaged patient. While brain damage is often viewed as an irreversible disorder, there is evidence that substantial recovery of function can occur, particularly when adequate retraining is provided. There are practical and empirical considerations that suggest that neuropsychological tests are currently the best tools available for behavioral assessment of brain-damaged patients. However, the results of these tests can be used not only diagnostically but also to identify target behavioral deficits that may be rehabilitated through systematic retraining efforts. Such rehabilitation efforts can be optimally planned, implemented, and evaluated through an alliance between the neuropsychologist, who identifies the ability and deficit pattern, and the behavior therapist, who devises and evaluates the retraining program. It is possible that the successes of behavior therapy in numerous clinical and educational applications can be repeated in the cases of brain-damaged patients. However, such success would appear to be contingent on appreciation of the high degree of specificity often seen in neurological deficit patterns and the great complexities involved in the relationships between brain function and behavior.     

Considerations in the choice of interobserver reliability estimates

Two types of interobserver reliability values may be needed in treatment studies in which observers constitute the primary data-acquisition system: trial reliability and the reliability of the composite unit or score which is subsequently analyzed, e.g., daily or weekly session totals. Two approaches to determining interobserver reliability are described: percentage agreement and "correlational" measures of reliability. The interpretation of these estimates, factors affecting their magnitude, and the advantages and limitations of each approach are presented.     

Two simple classes of mastery scores based on the beta-binomial model

Two simple classes of mastery scores which are suitable for hand calculations are presented for beta-binomial test score distributions combined with linear and cubic referral success. The models provide a simple way to explore the consequences of selecting an arbitrary mastery score. Such assessment would be useful whenever the test user is not willing to posta priori a loss ratio, but wishes to look at the various consequences before aiming at a particular score.     

Fitting and testing carroll's weighted unfolding model for preferences

A quadratic programming algorithm is presented for fitting Carroll's weighted unfolding model for preferences to known multidimensional scale values. The algorithm can be applied directly to pairwise preferences; it permits nonnegativity constraints on subject weights; and it provides a means of testing various preference model hypotheses. While basically metric, it can be combined with Kruskal's monotone regression to fit ordinal data. Monte Carlo results show that (a) adequacy of true preference recovery depends on the number of data points and the amount of error, and (b) the proportion of data variance accounted for by the model sometimes only approximately reflects true recovery.This study is based on a doctoral dissertation submitted to the University of Illinois at Urbana-Champaign. The author wishes to thank the members of his dissertation committee—Lawrence E. Jones, Chairman, Charles Lewis, Stephen Golding, Ledyard Tucker, and Nancy Wiggins—for their helpful comments.     

跨文化领导模式在跨国创业不同阶段的效能转化研究

以管理心理学的领导理论为基础,采用访谈、问卷调查和统计分析等方法,探讨三种跨文化领导模式在跨国创业不同发展阶段的效能转化。主要结论有:(1)变革型领导模式、创业型领导模式和交易型领导模式在跨国创业不同阶段的作用效能存在显著差异;(2)交易型领导模式的效能在跨国创业的成长阶段相对最大,成熟阶段相对最小;(3)创业型领导模式的效能在跨国创业的扩张阶段相对最大,成熟阶段相对最小;(4)变革型领导模式的效能在跨国创业的成熟阶段相对最大,成长阶段相对最小。     

理想情感及其影响的跨文化差异

理想情感是人们期望获得的情感状态。情感评估理论认为文化对理想情感的塑造有着重要影响,主要的影响途径有文化体验、文化价值观和社会文化变化。理想情感对个体会产生具有文化特异性的影响,主要会影响个体的偏好及选择行为、混合情绪体验、身心健康和社会认知决策。理想情感研究未来发展可以着眼于4个方向:使用纵向视角研究理想情感,进一步探索理想情感的前因变量,打造适合中国文化的心理健康标准和通过认识理想情感来消除文化隔阂。     

动机的结构与效应：基于动机连续体的视角

动机连续体是对内部动机、外部动机进行整合的心理学概念,其对内部动机和外部动机的争论提出了不同的假设。从大理论(grand theory)视角出发,对涉及上述两个概念的理论进行梳理,将自我决定理论与其他相关理论进行整合。由此展开对内部动机、外部动机结构的讨论,总结了动机的单维结构、多维结构和复杂结构假设下的理论新进展,分别论述在拮抗效应、累加效应和其他复杂效应等假设下动机对结果变量的影响,并展开不同效应对实践应用的讨论。     

归因疗法——一种重要的心理治疗方法

归因疗法是心理治疗的重要方法之一。迄今为止 ,人们已经发展了运用归因理论于治疗实践的两种一般模式 :“真归因疗法”引导患者用准确的归因代替错误的归因 ,“误归因疗法”引导患者用不准确而有益的归因代替准确而有害的归因。归因疗法受到了其他心理治疗理论的怀疑和批评。     

进化心理学择偶心理机制假设的跨文化检验

通过对404例天津和432例Boston征婚启事的内容分析,结果发现：（1）男性更关注未来异性配偶的相貌、身材信息,而女性更关注对方的资源与承诺信息,但天津男女征婚者在这两方面都表现得更为强烈;（2）男性随年龄增长,会倾向于更大程度地寻找比自己小的女性,而中美女性则较稳定;（3）Boston人的配偶选择年龄空间较天津人广;（4）在个性特质方面,天津人更关注承诺性,Boston人更关注精神性与“享乐性”。结果表明,进化心理学对男女间差异有较大解释力,但对中美之间的文化差异却缺乏足够说服力。
