Fisher与Neyman–Pearson的分歧与心理统计中的假设检验争议

假设检验思想的提出者Fisher与Neyman–Pearson在统计模型的方法论基础、两类错误的性质、显著性水平的理解、以及假设检验的功能等方面存在诸多分歧, 使得心理统计中最常用的原假设显著性检验模式呈现出隐含的各种矛盾, 从而引发了应用上的争议。心理统计不仅需要检讨现有检验模型的模糊之处和提出其他补充性的统计推论方式,更应注重反思心理统计的教育传统, 以建立更加开放和多元的统计应用视野, 使心理统计为更好地心理学研究服务。     

社会网络分析在心理研究中的应用

个体不是孤立存在的, 其心理与行为的变化常依赖于与他人存在的关系。社会网络分析正是考虑到了这种依赖性, 发展出相应的处理关系变量的方法。在介绍社会网络理论的中心思想、社会网络分析的基本概念、数据表示方法和研究方法以及在个体水平和关系水平上的静态统计模型后, 使用UCINET软件展现了处理关系数据的基本步骤, 并简述社会网络分析在人格心理学、发展与教育心理学和管理心理学中的应用。     

Comparing one-step m-estimators of location corresponding to two independent groups

Experience with real data indicates that psychometric measures often have heavy-tailed distributions. This is known to be a serious problem when comparing the means of two independent groups because heavy-tailed distributions can have a serious effect on power. Another problem that is common in some areas is outliers. This paper suggests an approach to these problems based on the one-step M-estimator of location. Simulations indicate that the new procedure provides very good control over the probability of a Type I error even when distributions are skewed, have different shapes, and the variances are unequal. Moreover, the new procedure has considerably more power than Welch's method when distributions have heavy tails, and it compares well to Yuen's method for comparing trimmed means. Wilcox's median procedure has about the same power as the proposed procedure, but Wilcox's method is based on a statistic that has a finite sample breakdown point of only 1/n, wheren is the sample size. Comments on other methods for comparing groups are also included.     

FATHER–CHILD PLAY DURING THE PRESCHOOL YEARS AND CHILD INTERNALIZING BEHAVIORS: BETWEEN ROBUSTNESS AND VULNERABILITY

Play observations with a total of 400 toddlers and preschoolers were videotaped and rated for Intensity and Quality of play with their parents. Parents were asked about perceived stress and personality characteristics (Big 5). Child's motor, cognitive skills, temperament, and internalizing behaviors were assessed. Study 1 investigated the robustness of play across child age and gender, and examined differences between fathers and mothers. Study 2 explored the vulnerability of play with fathers of children born preterm (PT‐fathers) and fathers who had experienced adverse childhoods (AC‐fathers). Study 3 investigated child internalizing behaviors. Intensity of play was maintained almost independently of child age and gender. It was similar for AC‐ and PT‐fathers, and similar to maternal Intensity. In contrast, paternal Quality of play was higher with boys and independent of fathers’ personality and perceived parenting stress whereas maternal Quality of play was higher with girls and linked to mothers’ perceived parenting competence, acceptability of the child, and neuroticism. AC‐fathers scored significantly low on Quality, as did PT‐fathers, but the Quality of their play became better with growing child age, birth weight, and cognitive (but not motor and temperament) scores. Finally, child internalizing behaviors were negatively related to paternal Quality of play.     

THE QUALITY OF FATHER–CHILD ROUGH‐AND‐TUMBLE PLAY AND TODDLERS’ AGGRESSIVE BEHAVIOR IN CHINA

The purpose of this study was to explore the influence of the quality of early father–child rough‐and‐tumble play (RTP) on toddler aggressive behaviors and more fully understand how child, mother, and father characteristics were associated with higher quality father–child RTP among contemporary urban Chinese families. Participants included 42 families in Changsha, China. Play observations of fathers and their children were coded for RTP quality. The specific RTP quality of father–child reciprocity of dominance was associated with fewer toddler aggressive behaviors, as rated by both fathers and mothers. Mothers’ democratic parenting attitudes were associated with higher quality father–child RTP. These findings suggest that higher quality father–child RTP may be one way in which some fathers influence children's expression of aggressive behaviors, and the quality of father–child RTP may be influenced by the broader family, social, and cultural contexts.     

States on Pseudo MV-Algebras

Pseudo MV-algebras are a non-commutative extension of MV-algebras introduced recently by Georgescu and Iorgulescu. We introduce states (finitely additive probability measures) on pseudo MV-algebras. We show that extremal states correspond to normal maximal ideals. We give an example in that, in contrast to classical MV-algebras introduced by Chang, states can fail on pseudo MV-algebras. We prove that representable and normal-valued pseudo MV-algebras admit at least one state.     

PTEN、p53和BAG-1在三阴乳腺癌中的表达及意义

为了研究PTEN、p53和BAG-1在三阴乳腺癌中的表达情况及临床病理意义,并讨论三者之间的关系.采用免疫组织化学SP法检测89例三阴乳腺癌中PTEN、p53、BAG-1的表达,其阳性表达率分别为44.9％、47.2％、73.0％,三者的表达均与患者的病理组织学分级、淋巴结转移情况有关（P＜0.05）.PTEN的表达与p53、BAG-1表达呈负相关;BAG-1与p53的表达呈正相关,提示三者在三阴乳腺癌中的表达存在一定关联性,临床上联合检测三者可能为TNBC预后评估、患者的个体化治疗提供一定的参考.     

Refuser sans dire non : étude d’un jeu de langage dans une transaction entre un patron et un employé

The aim of this paper is to go on with the articulation between the notions of form of life and language game started by Agnoletti (2006). In this way, we want to show the links between language game and activity through the study of pieces of verbal interaction coming from a professional transaction between a chief and his employee. By using the hierarchical and functional analysis (Roulet et al., 1985), we show regularities, both at the level of the structure of the interaction and in that of the sentences and vocabulary. We make then a relationship between the linguistic forms and the context in which they appear and we consider that we have to deal with a language game which has two modalities: appeal to the rule and the charge. These forms are related to power and authority.
