One night of sleep deprivation affects reaction time, but not interference or facilitation in a Stroop task

The Stroop color-naming task is one of the most widely studied tasks involving the inhibition of a prepotent response, regarded as an executive function. Several studies have examined performance on versions of the Stroop task under conditions of acute sleep deprivation. Though these studies revealed effects on Stroop performance, the results often do not differentiate between general effects of sleep deprivation on performance and effects specifically on interference in the Stroop task. To examine the effect of prolonged wakefulness on performance on the Stroop task, we studied participants in a 40-h "constant routine" protocol during which they remained awake in constant conditions and performed a Stroop color-naming task every two hours. We found that reaction time was slowest when the color and word did not match (incongruent), fastest when the color and word did match (congruent), and intermediate when participants named the color of the non-word stimulus (neutral). Performance on all three trial types degraded significantly as a function of time awake. Extended wakefulness did not significantly change the additional time needed to respond when the color and word did not match (Stroop interference), nor did it change the amount of facilitation when color and word matched. These results indicate that one night of sleep deprivation influences performance on the Stroop task by an overall increase in response time, but does not appear to impact the underlying processes of interference or facilitation. The results suggest that the degree to which an "executive function" is affected by sleep deprivation may depend on the particular executive function studied and the degree to which it is subserved by the prefrontal cortex.     

An outcome evaluation study of a psycho‐educational course in a primary care setting

Rationale: To date relatively little research has examined the effectiveness of psycho‐educational courses provided in a primary care setting to adults with mild‐to‐moderate mental health concerns. Aims: To determine whether group psycho‐education could be a viable alternative to individual counselling by (1) assessing the clinical effectiveness of an 8‐week psycho‐educational course, and (2) examining the group outcomes in comparison with individual treatment outcomes from a previous study in the same counselling service. Method: A total of 57 participants attending a psycho‐educational course provided data over a 36‐month period, using the Clinical Outcomes in Routine Evaluation – Outcome Measure (CORE‐OM) pre‐ and post‐intervention. A comparison was then made with the data of 58 previous participants of individual counselling evaluation, using the same CORE‐OM system. Results: Participants reported significantly lower levels of psychological distress after attending the course and these results are comparable to outcomes measured in the same service for individual counselling, indicating that group interventions could be considered a legitimate alternative to individual counselling, thus increasing cost effectiveness and reducing waiting times. Limitations of the study and implications for practice and further investigation are considered.     

Cultural ruptures in short‐term therapy: Working alliance as a mediator between clients' perceptions of microaggressions and therapy outcomes

Aim: To determine whether or not clients' perceptions of microaggressions varied based on their own and the therapist's race/ethnicity and whether or not they would be negatively related to the effectiveness of therapy and if the working alliance would mediate this effect. Method: The study utilised a cross‐sectional, retrospective, methodology. Clients were recruited from a large university counselling centre in the United States (N=232 clients and 29 therapists). Results: Neither clients' race/ethnicity, therapists’ race/ethnicity, nor client‐therapist ethnic matching predicted perceptions of microaggressions. Clients' ratings of microaggressions were negatively associated with their psychological wellbeing; however, this effect was mediated by clients' ratings of the working alliance. Implications: Therapists should take into account the cultural messages they may be conveying to both white and racial/ethnic minority clients. Therapists should develop strategies that are consistent with a general therapeutic approach that promotes discussions about culture with their clients and, most importantly, should attend to the therapeutic relationship.     

Hewitt多维完美主义量表在中学生群体中的修订

本研究以中学生群体为样本,对Hewitt多维完美主义量表(HMPS)进行修订。首先根据我国文化背景和青少年发展的具体状况建立了理论构想,接着对原量表进行了四次测查和检验修订,我们首先把指向他人和社会期望两个维度上的反向题改成正向题,并对所有项目的表述做了必要的修改;然后根据随后的测查结果进行了各维度和项目上的修改;最后删除了指向自我维度上的1个项目、指向他人维度上的2个项目和社会期望维度上的6个项目,修订后的HMPS量表的内部一致性信度α系数为0.91,指向自我、指向他人、社会期望的α系数分别为0.89,0.80,0.78,重测信度分别为0.80,0.79,0.67,与Frost多维完美主义量表中文修订版的相关分别为0.58,0.38,0.57。     

社会公正与政治信任：民众对政府的合作行为机制

胡锦涛在中共十八大上提出：必须坚持维护社会公平正义。对社会公正的认知直接决定着民众的政治信任, 进而影响民众对政府的合作。近年来频发的群体性事件即是非合作行为的典型表征。然而, 国内外研究中至今没有直接探讨社会公正与政治信任影响合作行为的实证支持, 更无法进一步揭示其作用于合作行为的过程和条件。鉴于此, 本研究将社会公正分为分配公正和程序公正, 将政治信任分为工具信任和情感信任, 采用实验室研究、现场研究和问卷调查研究相结合的方法, 探讨社会公正对合作行为的过程机制, 建立其通过工具信任和情感信任作用于合作行为的双路径模型; 并进一步分析结果依赖性对这一路径模型的调节作用。本研究有望提出社会公正与政治信任影响合作行为的双路径模型及其调节变量, 一方面在理论上深化和拓展本领域的研究, 另一方面实践中通过提升公正感、强化过程变量(政治信任)、干预调节变量(结果依赖性)等策略促进合作行为。     

Taxicab Correspondence Analysis

Taxicab correspondence analysis is based on the taxicab singular value decomposition of a contingency table, and it shares some similar properties with correspondence analysis. It is more robust than the ordinary correspondence analysis, because it gives uniform weights to all the points. The visual map constructed by taxicab correspondence analysis has a larger sweep and clearer perspective than the map obtained by correspondence analysis. Two examples are provided. This research was financed by the Natural Sciences and Engineering Research Council of Canada. The author thanks Serge Vienneau for his help regarding the graphical displays, and also thanks the editor, associate editor, and two reviewers for their constructive comments.     

Component Models for Fuzzy Data

The fuzzy perspective in statistical analysis is first illustrated with reference to the “Informational Paradigm” allowing us to deal with different types of uncertainties related to the various informational ingredients (data, model, assumptions). The fuzzy empirical data are then introduced, referring to J LR fuzzy variables as observed on I observation units. Each observation is characterized by its center and its left and right spreads (LR₁ fuzzy number) or by its left and right “centers” and its left and right spreads (LR₂ fuzzy number). Two types of component models for LR₁ and LR₂ fuzzy data are proposed. The estimation of the parameters of these models is based on a Least Squares approach, exploiting an appropriately introduced distance measure for fuzzy data. A simulation study is carried out in order to assess the efficacy of the suggested models as compared with traditional Principal Component Analysis on the centers and with existing methods for fuzzy and interval valued data. An application to real fuzzy data is finally performed. We would like to express our gratitude to the Editor, the Associate Editor, and the Referees whose comments and suggestions improved significantly the quality of the paper.     

Expected consequences of anger‐related behaviours

In a study with 140 participants (66 men, 74 women), we investigated behaviour outcome expectancies (cognitive, affective and relational) regarding a broad group of anger‐related behaviours (e.g. hit someone, run away). Results of a three‐mode component analysis indicated that behaviour outcome expectancies vary considerably, depending on the behaviour (aggressive versus nonaggressive ones), the consequence (consequences related to the self versus consequences for the anger) and the individual. The findings are discussed in the context of catharsis theory, emotion regulation and functionalistic accounts of emotion‐related behaviour. Copyright © 2006 John Wiley & Sons, Ltd.
