中国创伤后应激反应量表在大学生群体中的应用

采用以中国文化为背景编制的“中国自然灾难幸存者创伤后应激反应量表(CPI)”, 对芦山地震灾区某大学1057名学生进行测试, 考察CPI在地震后大学生人群的应用, 并探讨PTSD的影响因素。结果发现, 性别、主观害怕体验和D型人格等因素能够预测PTSD症状的发生。CPI在地震受灾的大学生群体中具有良好的信效度, 可用于PTSD症状严重程度的评估。     

Time, tense, truth

A theory of time is a theory of the nature of temporal reality, and temporal reality determines the truth-value of temporal sentences. Therefore it is reasonable to ask how a theory of time can account for the way the truth of temporal sentences is determined. This poses certain challenges for both the A theory and the B theory of time. In this paper, I outline an account of temporal sentences. The key feature of the account is that the primary bearers of truth-values are not utterances, but sentences evaluated with respect to a time. I argue that unlike other views, the present proposal can meet the challenges faced both by the A and the B theory.     

中国苏州与美国15岁学生数学学习特征比较

本研究首次采用"学生能力国际评估计划"(PISA)的学生问卷,对苏州市504名15岁学生的数学学习心理及特征进行了调查研究,并与美国学生数据作比较.调查表明:中国苏州大多数学生在数学学习上具有较强的竞争意识与合作意识,他们会运用多种学习策略;那些对数学有更大兴趣和更高动机的学生,有更积极的自我概念和更少的焦虑体验.中美两国学生的数学学习特征性别差异显著.     

A Bishop Saving ‘Singers’: Tales of Torture in Pinochet's Chile

Abstract : The article provides a brief biographical introduction of Lutheran Bishop Helmut Frenz, co‐founder of the Committee for Peace, credited with saving at least 6,000 lives of persecuted Chileans following the September 1973 military coup at the hands of the brutal general Agosto Pinochet. Excerpts from Frenz' book, Mi Vida Chilena, document Pinochet's acknowledgment that torture was the regime's official policy, and share the poignant story of one suspected leftist's brutal torture.     

Need for Cognition and Affective Orientation as Predictors of Sales Performance: An Investigation of Main and Interaction Effects

Two constructs—need for cognition (NFC) and affective orientation (AO)—might be helpful in explaining and ultimately predicting two measures of sales performance: a self-rated behavioral measure and an objective sales measure. Specifically, we hypothesize (1) a positive relationship between NFC and sales performance; (2) a positive relationship between AO and sales performance; and (3) a positive interaction effect between NFC and AO on sales performance. The results of this study revealed both NFC and AO correlated with self-rated behavioral performance but only NFC correlated with both performance measures; suggesting that need for cognition may be the more influential of the two for sales organizations concerned with selling behaviors as well as sales outcomes. The hypothesized interaction effect was not supported.     

Message content,group identification and the intergroup sensitivity effect: Responses to the message and recognition memory

An intergroup sensitivity effect (ISE) is people's tendency to react more negatively to a criticism when it was made by an outgroup member than when the same criticism was made by an ingroup member. The present study investigated variation in ISE when the criticism was varied in terms of valence (absence of positive qualities or presence of negative qualities) and level of abstraction (traits or behaviours). Dependent measures were emotional reactions to the criticism, perceived constructiveness, ingroup bias, and recognition memory for the criticism. All participants showed an ISE to the negative abstract criticism. In addition, consistent with the social identity account of ISE, participants' levels of identification with their ingroup moderated the ISE in some of the measures.     

Principles versus procedures in making health care coverage decisions: addressing inevitable conflicts

It has been suggested that focusing on procedures when setting priorities for health care avoids the conflicts that arise when attempting to agree on principles. A prominent example of this approach is “accountability for reasonableness.” We will argue that the same problem arises with procedural accounts; reasonable people will disagree about central elements in the process. We consider the procedural condition of appeal process and three examples of conflicts over coverage decisions: a patients’ rights law in Norway, health technologies coverage recommendations in the UK, and care withheld by HMOs in the US. In each case a process is at the center of controversy, illustrating the difficulties in establishing procedures that are widely accepted as legitimate. Further work must be done in developing procedural frameworks. The opinions expressed are the authors’ own. They do not reflect any position or policy of the National Institutes of Health, US Public Health Service, or Department of Health and Human Services.

Empirical validation of a procedure to correct position and stimulus biases in matching-to-sample

The development of position and stimulus biases often occurs during initial training on matching-to-sample tasks. Furthermore, without intervention, these biases can be maintained via intermittent reinforcement provided by matching-to-sample contingencies. The present study evaluated the effectiveness of a correction procedure designed to eliminate both position and stimulus biases. Following key-peck training, a group of 6 pigeons had extended exposure to matching-to-sample contingencies without a correction procedure, a group of 4 pigeons was briefly exposed to a simultaneous matching-to-sample procedure to assess biases prior to exposure to the correction procedure, and a group of 5 pigeons was exposed directly to the correction procedure. The correction procedure arranged that every time an incorrect match was made, the trial configuration was repeated on the subsequent trial until a correct match was made. Extended exposure to matching-to-sample contingencies without a correction procedure was associated with reduced biases eventually for most subjects, but rapid development of near-perfect accuracy and bias-free performance was observed upon the implementation of the correction procedure regardless of the type of bias. Bias-free performance was maintained following subsequent exposure to a zero-delay MTS procedure.
