急性心理性应激诱发的神经内分泌反应及其影响因素

急性心理性应激源分别通过下丘脑-脑垂体-肾上腺轴(hypothalamus–pituitary–adrenal axis,HPAA)和交感神经-肾上腺髓质轴(sympathetic-adrenal medulla axis)诱发神经内分泌反应。唾液皮质醇被认为是检测急性心理性应激所诱发的HPA轴反应的稳定指标。以特里尔社会应激测试(Trier Social Stress Test,TSST)及其变式作为应激源, 以HPA轴的反应作为应激指标, 影响个体在急性心理性应激情境中发生特异性神经内分泌反应的因素主要包括人口统计学、环境和应激频率三大方面, 未来应加强急性心理性应激所诱发的神经内分泌反应的纵向研究。     

The Sternberg Triarchic Abilities Test (STAT) as a measure of academic achievement and general intelligence

The degree to which practical, creative, and analytical abilities, measured by the Sternberg Triarchic Abilities Test (STAT) (Sternberg, 1993), significantly contribute to the prediction of academic achievement, independent of general intelligence, was investigated. Although Sternberg et al. (2000) claim that the STAT is not related to, nor a measure of, general intelligence, data obtained by Sternberg, Ferrari, Clinkenbeard, and Grigorenko (1996), found that STAT scores were significantly correlated with measures of general intelligence. In the present study, introductory psychology midterm examination grades, STAT scores, and Wonderlic Personnel Test scores (as a measure of general intelligence), were obtained from undergraduate students at the University of Western Ontario (N=150). Total STAT scores and each of the STAT subsection scores were significantly related to Wonderlic test scores, P<0.01, and the STAT subsections were significantly related to each other, P<0.01. The partial correlations between midterm grades and creative, practical, analytical, and total STAT scores, with the variance due to the Wonderlic test removed, were also found to be significant for practical and for total STAT scores, P<0.05, but nonsignificant for creative and analytical STAT scores. A factor analysis including midterm examination grades, the Wonderlic test, and each of the STAT subsections revealed a single general factor. Thus, some results supported Sternberg but others were contrary to his claims.     

采用理想点方法检验生活取向测验及其修订版的单维性

该文从项目反应过程出发,认为可能是由于原有的维度分析方法将生活取向测验（LOT）及其修订版（LOT-R）这两个测验的项目反应理想点过程错误地限定为优势过程,导致两个测验违背单维性的结论;进而采用主成分分析的未旋转成分负荷散点图和对应分析的维度分数散点图,并结合项目相关矩阵法验证LOT和LOT-R的维度。结果显示LOT-R的单维性得到了验证,LOT由于包含两个测量应对的项目而导致违背单维性。最后作者提出应该与理想点过程相一致的心理计量学模型对LOT-R的数据进行分析。

对不同类网络信息态度的IAT研究

采用内隐联想测验（Implicit Association Test简称IAT）对不同类网络信息态度进行测量和研究。结果显示,无论是词汇测验还是图片测验,相容联结的平均反应时均小于不相容联结平均反应时,且差异显著。结论：（1）人们对于不同类的网络信息有一定的偏好,产生了IAT效应;（2）与政策信息相比,被试对娱乐信息的形式和内容（即实验中所采用的截图与词语）都表现出显著的偏好;（3）在内隐社会认知领域,存在对娱乐信息的偏好,且男女之间无性别差异。     

Criterion-related bias with the guide to the assessment of test-session behavior for the WISC-III and WIAT: Possible race/ethnicity, gender, and SES effects

Using the Guide to the Assessment of Test-Session Behavior for the WISC-III and WIAT (GATSB), Anglo examiners recorded test observations for 969 children between the ages of 6 and 16 years. The children came from the standardization and validity-study samples of GATSB ratings completed with the Wechsler Intelligence Scale-Third Edition (WISC-III) (Wechsler, 1991). The sample differed by race (Anglo, black, Latino), socioeconomic status (SES) (high, middle, low), and gender. GATSB ratings and WISC-III Verbal, Performance, and Full Scale IQs were compared. Correlations between the GATSB and WISC-III were generally moderate (average R = -.27). Children who exhibited higher levels of avoidance, inattentiveness, and uncooperative behaviors while being tested tended to exhibit lower WISC-III scores. This pattern held true for Anglos, blacks, and Latinos; for girls and boys; and for those from high-, middle-, and low-SES homes. Evidence was generally absent that Anglo examiners display bias in black-Anglo, gender, or SES comparisons. However, consistent differences were noted between Latino and Anglo children. Examiners tended to rate Latinos as displaying better test behaviors than Anglos when children's IQs were below average, but comparable when IQs were average and above. Thus, the GATSB generally displayed similar intrasession validities for children who differ by race/ethnicity, gender, and SES.     

Assessing children's social skills: Validation of the Behavioral Assertiveness Test for Children (BAT-C)

The present study assessed the relationship between specific child responses on the Behavioral Assertiveness Test for Children (BAT-C) and sociometric indices obtained from peers. Fourth and fifth graders completed peer nominations of their best friends and the children they most admired, peer ratings of likeability, and the BAT-C. Sociometric status was determined by classifying each child as either high or low on peer nominations and peer ratings. Examination of the effects of sociometric status as moderated by race and sex revealed several significant differences in BAT-C responses. Children who were more highly liked or were often named as best friends were significantly less compliant. Differential responding on several additional verbal categories was observed as a function of the interaction between sociometric status and race and/or sex. These findings not only demonstrate the validity of several response categories observed on the BAT-C, but also suggest that in social skills training, different component responses may be targeted across child populations.The authors wish to express their appreciation to Jean Birbilis, Candace Conley, Tony Genoff, Marieta Knopf, and Donna Wadley for their assistance in data collection and analysis.     

Reactions to DMT as related to psychotic and borderline personality organization

Thirty-one inpatients in a psychiatric clinic were assessed with DMT and the Structural Interview. In order to assemble every relevant reaction that an individual might have to a percept-genesis, 130 DMT variables were formed. The results were first subjected to a quality control of the DMT-scores and then subjected to partial least squares in latent variables (PLS) discriminant analysis. The analysis showed that it is possible to separate patients with psychotic PO (PPO) from those with borderline PO (BPO) by means of the 130 variables. The BPO group is characterized by aggressive manifestations, sensitivity to threat, identity lability and various transformations of the Hero gestalt. The PPO group, on the other hand, is characterized by high threshold values for perception, lack of identity, denial and repression of the peripheral person at a late-phase level. There are other perceptual reactions that are important predictors of PO than the defence categories of the manual. These perceptual reactions do not correspond to the traditional psychodynamic defence mechanisms. Our conclusion is that principal component analysis (PCA) and PLS are useful methods of finding discriminating patterns of perceptual reactions to the DMT for patients with different PO.     

Evidence for the external validity of a social simulation measure of social skills

Two studies were conducted in order to obtain evidence regarding the external validity of a social simulation measure of social skills. The first study employed a contrasted group design, with the groups consisting of National Guardsmen and psychiatric patients. As predicted, trained judges rated the performances of the National Guardsmen in the simulations as more skillful and appearing less anxious than the psychiatric patients. In the second study, trained judges' ratings of psychiatric patients' performances in the simulations were found to be significantly related to ratings made by interviewers who had conducted a structured social history interview with the patients, nurses' ratings based on their observations of patients after 3 days on the psychiatric unit, a research assistant's ratings based on contact with the patient during the experiment, and finally, the subject's own self-ratings. In discussing the findings, it is hypothesized that one reason why support was found for the external validity of the simulation strategy in this study, in contrast to some previously reported studies, was the use of molar ratings in this study as opposed to the more molecular rating procedures used in those previous studies.These studies were funded in part by a research grant from the Veterans Administration.     

The measurement of cognitive impulsiveness: Psychometric properties of two automated adult versions of the Matching Familiar Figures Test

An automated version of the Matching Familiar Figures Test (MFFT) was administered to undergraduates, along with a parallel from. The latency-errors correlation (–0.61) was higher than that reported for most studies in children and weakly supports the view that the correlation increases with age. Repeated exposure resulted in improved performance, which was faster, more accurate, and more efficient, but there was no effect on impulsiveness. Reliability and internal consistency of both forms were acceptably high and the forms were comparable. Use of the univariate measures (impulsiveness-reflectiveness and efficiency-inefficiency) is superior to other scoring methods.Supported in part by a grant from the Nuffield Foundation, England.
