生物反馈疗法对大学生考试焦虑的治疗作用

探讨生物反馈疗法对大学生考试焦虑的治疗作用。在某大学随机抽取学生1500名,采用考试焦虑量表进行筛查,选取焦虑组和对照组各30名。利用生物反馈疗法进行干预,采用脑电α波相对功率、肌电和皮电导联进行检测,每周2次,持续4周。结果表明：1.经过4周的干预,焦虑组干预前后各生理指标存在差异;2.生物反馈疗法干预考试焦虑在疗效上存在性别差异。结论：生物反馈疗法能有效降低大学生考试焦虑水平,对其治疗取得良好的效果。     

青少年道德判断能力的研究

德国道德心理学家林德提出“道德行为与发展的双面理论”,并设计了著名的“道德判断测验”,在20多年的研究中取得了很多重要成果。我们以中文版的“道德判断测验”为测量工具,以724名12-27岁青少年学生为被试进行实证研究,研究结果表明:学生的C分数随年级提高而有所提高,但不同年级之间有一定波动,说明学校教育有助于提高学生的道德判断能力,但存在不稳定因素。男女生C分数不存在显著差异,学校内部各年级之间也不存在显著差异,不同性质的学生之间不存在显著差异;     

Marginal maximum likelihood estimation of item parameters: Application of an EM algorithm

Maximum likelihood estimation of item parameters in the marginal distribution, integrating over the distribution of ability, becomes practical when computing procedures based on an EM algorithm are used. By characterizing the ability distribution empirically, arbitrary assumptions about its form are avoided. The Em procedure is shown to apply to general item-response models lacking simple sufficient statistics for ability. This includes models with more than one latent dimension.Supported in part by NSF grant BNS 7912417 to the University of Chicago and by SSRC (UK) grant HR6132 to the University of Lancaster.We are indebted to Mark Reiser and Robert Gibbons for computer programming.

加工水平对不同类型内隐记忆测试的影响

许多内隐记忆研究表明 ,加工水平影响外显记忆而不影响内隐记忆 ,这样的实验结果被一些研究者认为是外显记忆与内隐记忆系统分离的重要依据之一。实际上 ,内隐记忆研究中的加工水平问题一直存在争议 ,加工水平效应作为两类记忆系统分离的依据是不充分的。在我们的这项实验中 ,结果表明 ,加工水平影响概念样例生成这种内隐记忆测试而不影响知觉辨认测试。     

Defense Mechanism Test (DMT) and Kernberg's theory of personality organization related to adolescents in psychiatric care

75 adolescent psychiatric patients were diagnosed with the perceptual projective test the Defense Mechanism Test (DMT) and also according to Kernberg's theory of personality organization (PO). The test protocols were scored in respect of 130DMT variables and analyzed by means of partial least squares (PLS) discriminant analysis. The objective was to try to separate the three types of PO, psychotic (PPO), borderline (BPO) and neurotic (NPO) by means of the DMT and also to compare the results with a similar study on adult psychiatric patients. The results showed that it is possible to separate significantly the three groups of PO. The BPO group seemed to be heterogeneous. The results were fairly similar to those obtained with adult psychiatric patients. The overall results supported the concurrent validity of Kernberg's theory of PO and for the DMT as well. The DMT seems to be a useful diagnostic method in respect of adolescent psychiatric patients.     

The Relationship of Cognitive Development to Age, When Education and Intelligence Are Controlled For

In this study 165 volunteers aged 18–87 were recruited from educational, employment, church, and social organizations and administered 3 paper-and-pencil instruments: the Quick Test, a measure of verbal–perceptual intelligence; the Scale of Intellectual Development, a Perry measure of cognitive development; and an inventory of life experiences. Age was found to be negatively related to cognitive development, as was extent of participation in community or church activities, whereas intelligence and education were positively so related. Less dualistic thinking and more relativistic thinking were related to higher educational achievement. Nevertheless, dualistic thinking was found to increase among older age groups, even with intelligence and education controlled for.     

个人拟合指数对人格测验的影响及意义

个人拟合指标是考察心理测验中偏差得分模式的新方法。研究中考察了G、C、MCI、U3、U、W、ECI6、L等8个拟合指标对艾森克人格问卷信效度的影响,以及各指标与正反向题回答不一致项目数的相关。结果表明,删除不同比例拟合程度不好的个体后,测验的信效度明显提高。同时PFS可鉴别人格测验中的默认反应偏差。各指标中l对测验信效度的改善效果最为理想。     

Anaphoric agreement violation: an ERP analysis of its interpretation

In the present study we analyzed the processing of grammatically anomalous sentences like "The famous dancer were nervously preparing herself/themselves to face the crowd.", which contains two anomalies, one early and one late. We investigated how processing of the later anomaly (at the pronoun 'herself' or 'themselves') was affected by the processing of the early anomaly (at 'were'). We considered two processing scenarios involving the first anomaly: (1) The representation of the subject-verb number agreement error at the first verb is coerced to match the verb, rendering 'herself' anomalous; (2) The representation of the subject-verb agreement error is coerced to match the subject noun, rendering 'themselves' anomalous. Our dependent measure was event-related scalp potentials (ERPs). When the pronoun disagreed with the verb (and agreed with the subject), a P600 was recorded, while the opposite condition elicited no reliable effect. Our data suggest that interpretation of reflexive pronouns involves the reactivation of multiple lexical items, verbs included.     

A comparison of normative data for the Trail Making Test from several countries: equivalence of norms and considerations for interpretation

The Trail Making Test may not be equivalent across cultures, i.e., differences in the scores across different cultures may not reveal real differences in the ability of the subjects on the construct being measured. In order to assess this hypothesis, normative samples from ten different countries were compared. Age decade subgroups across samples were ranked based on mean time taken to complete each part of the task. Large Z scores differences were found between these samples when comparing the first with the second, and the last in the rank. These differences were significant even when age and education were comparable across samples. Following Van de Vijver & Tanzer (1997), several possible sources of bias were identified. Incomparability of samples and administration differences were the most likely factors accounting for differences. Because of the lack of validity studies in the countries considered, no firm conclusions could be obtained regarding construct bias. Although the TMT may be measuring visual scanning, psychomotor speed and mental flexibility, normative data from different countries and cultures are not equivalent which might lead to serious diagnostic errors.
