Preliminary validation of a Chinese version of the State-Trait Anger Expression Inventory-2

The increased globalization of psychology and related fields necessitates the availability of psychometric instruments in a number of languages, countries and cultures. Unfortunately, research on anger and aggression in Chinese populations has suffered from a lack of valid and reliable measurement instruments. Therefore, the State-Trait Anger Expression Inventory-2 (STAXI-2) was translated into Chinese (Chinese STAXI-2). Two samples of Hong Kong Chinese ( N  = 489 and N  = 775) completed the Chinese STAXI-2. Participants in the second sample also completed measures of anger rumination and aggression. Confirmatory factor analysis (CFA) of responses from the first sample resulted in the loss of nine items from the 57 original items due to misspecification. A second CFA, using responses from the second sample, supported the construct validity of the modified scale. Moderate correlations were observed with measures of aggression and anger rumination, and significant differences were found between males and females on three anger expression subscales (Anger Expression-In, Anger Control-Out, and Anger Control-In). The preliminary evidence suggests that the abbreviated inventory may be a useful measure of state and trait anger, and anger expression in some Chinese populations.     

创伤后成长：5·12地震创伤的新视角

创伤后成长是人们与主要的生活危机斗争后所体验到的一种积极的心理改变。对此概念的认识存在着结果与策略、建设功能与幻想功能、认知成分与行为成分的争论。对它的解释模型包括经历困难的力量、心理准备和存在的再评价。而它与心理健康的关系仍存在争议。建议此领域的研究应从概念澄清入手,开展过程研究和纵向研究,建立行为指标,关注其临床应用,进行本土化研究,并为5·12震后心理重建工作提供新的思路     

The Augustinian methodological family of psychology

In his Investigations, Wittgenstein employed a quotation from Augustine to capture certain of the essential features of an incoherent conception of language that he believed was at root of many of the dominant theories of meaning of his day. It is argued in the current paper that this very same Augustinian conception of language (ACL) is the foundation of some of the most influential methodological orientations of present-day psychological science, and, as a result, these orientations suffer from a range of ACL-induced incoherences. This thesis is illustrated by way of a case study drawn from the construct validation literature.     

非预想刺激的运动速率对无意视盲的影响

无意视盲是指由于对某些事物的专注而导致的眼前对象被忽视的现象。它受到诸如非预想刺激的位置、大小、颜色; 非预想刺激与注意刺激之间的关系; 被试的年龄、专业知识、加工能力等诸多因素的影响。本文通过改进的MR范式考察了“等时”和“等距”条件下非预想刺激的运动速率对无意视盲的影响。实验结果显示: (1)非预想刺激的运动速率和其呈现时间对无意视盲的比率有显著影响; (2)在一定的呈现时间范围内, 视盲率随运动速率的升高而降低, 但当维持相等的运动距离时, 视盲率没有显著变化; (3)当呈现时间超出一定范围时, 运动速率对无意视盲的影响急剧减小, 即呈现时间制约着运动速率对无意视盲的影响, 两者间呈倒U型曲线关系。文末就实验结果进行了详细分析和讨论。     

潜变量交互效应建模: 告别均值结构

潜变量交互效应建模研究近年来有了长足的发展, 但模型中被认为不可缺少的均值结构往往让实际应用工作者却步。本文首先分析了潜变量交互效应模型中均值结构产生的根源; 然后讨论了指标变换与均值结构的关系; 接着提出了一个均值为零的潜变量交互结构, 所建立的模型不需要均值结构, 却不会改变主效应和交互效应等参数; 最后用模拟例子对无均值结构和有均值结构的两种模型的参数估计进行了比较, 结果符合理论预期, 困扰人们多年的均值结构问题从此可以终结。     

胰岛素样生长因子结合蛋白3mRNA在肾癌中的表达

为探讨胰岛素样生长因子结合蛋白3（IGFBP-3）mRNA在肾癌（RCC）中的表达,采用半定量RT-PCR方法进行检测,检测56例RCC组织标本及56例癌旁组织标本中IGFBP-3的表达。结果显示RCC与癌旁组织之间IGFBP-3表达差异有显著性（P〈0.05）,IGFBP-3在透明细胞癌的强阳性表达,高于其他病理类型（P均〈0.05）,并与病理分级相关。因此,IGFBP-3在RCC组织中的表达具有显著性,其在肾透明细胞癌中的强阳性表达具有特异性。     

Examining the core: Relations among reading curricula, poverty, and first through third grade reading achievement

Policy changes at the federal and state level are endeavoring to improve student achievement at schools serving children from lower-SES homes. One important strategy is the focus on using evidence-based core reading curricula to provide a consistent framework for instruction across schools. However, rarely have these curricula undergone rigorous comparative testing. Therefore, the purpose of this study was to compare the effects of six core reading curricula on oral reading fluency growth, while appraising whether these effects differ by grade level and for children living in lower socioeconomic (SES) households. Over 30,000 students in first through third grade Florida Reading First classrooms comprise this academically and economically diverse cross-sectional. Hierarchical Linear Modeling was used to model latent growth curves for students' reading fluency scores over the school year. Growth curves revealed differences across curricula as well as between students of lower and higher SES, suggesting that reading fluency growth trajectories for curricula varied depending on student SES and grade level. Findings indicate that while there are similarities among curricula, they sometimes differ in their ability to promote reading skill growth. Differences by grade level and SES were also detected. However, many of these differences were small. Implications for the use of curriculum as a conduit for improving reading instruction are discussed.     

Desensitization to media violence over a short period of time

This study investigated the desensitization to violence over a short period of time. Participants watched nine violent movie scenes and nine comedy scenes, and reported whether they enjoyed the violent or comedy scenes and whether they felt sympathetic toward the victim of violence. Using latent growth modeling, analyses were carried out to investigate how participants responded to the different scenes across time. The findings of this study suggested that repeated exposure to media violence reduces the psychological impact of media violence in the short term, therefore desensitizing viewers to media violence. As a result, viewers tended to feel less sympathetic toward the victims of violence and actually enjoy more the violence portrayed in the media. Additionally, desensitization to media violence was better represented by a curvilinear pattern, whereas desensitization to comedy scenes was better represented by a linear pattern. Finally, trait aggression was not related to the pattern of change over time, although significant effects were found for initial reports of enjoyment and sympathy. Aggr.

Defining a Family of Cognitive Diagnosis Models Using Log-Linear Models with Latent Variables

This paper uses log-linear models with latent variables (Hagenaars, in Loglinear Models with Latent Variables, 1993) to define a family of cognitive diagnosis models. In doing so, the relationship between many common models is explicitly defined and discussed. In addition, because the log-linear model with latent variables is a general model for cognitive diagnosis, new alternatives to modeling the functional relationship between attribute mastery and the probability of a correct response are discussed.     

Intergenerational predictors of diurnal cortisol secretion in early childhood

The present study examined potential intergenerational links that may contribute to atypical patterns of diurnal cortisol secretion in early childhood. Salivary cortisol samples were collected across 1 waking day in 36 pre‐school children whose mothers are participants in an ongoing longitudinal project. Hierarchical Linear Modeling (HLM) identified statistically significant predictors of individual differences in daily cortisol trajectories. Children displayed relatively low post‐awakening values and flatter cortisol trajectories across the day as a function of unsupportive maternal behaviour, second‐hand smoke and maternal histories of social withdrawal in childhood. These results suggest that individual differences in young children's pattern of diurnal cortisol are associated with a variety of current and historical maternal characteristics and behaviours. The identification of intergenerational predictors of children's diurnal neuroendocrine functioning may provide new insights into the transfer of health and developmental risk from parent to child.
