空间行为关系类比匹配中客体相似性的作用

客体相似性在类比匹配中的作用,是一直存在着争论的问题。该研究通过交叉匹配结合与分离的材料设计,控制类比源和类比目标之间不同相似性,探讨了客体相似性在儿童和成人空间行为关系类比匹配中的作用。实验一通过让儿童和成人完成单目标匹配任务,检验客体相似性对儿童和成人类比匹配影响的不同。实验二采用眼动技术对客体相似性在成人类比匹配过程中的作用进行分区域探讨。结果发现,客体相似性影响儿童空间行为关系类比匹配的成绩,但不影响成人的成绩。成人类比匹配的过程受到结合在关系结构之内的客体相似性的影响。我们提出优先-限制调整观点解释客体相似性在类比匹配中的作用。     

A Bayesian predictive analysis of test scores

In the classical test theory, a high-reliability test always leads to a precise measurement. However, when it comes to the prediction of test scores, it is not necessarily so. Based on a Bayesian statistical approach, we predicted the distributions of test scores for a new subject, a new test, and a new subject taking a new test. Under some reasonable conditions, the predicted means, variances, and covariances of predicted scores were obtained and investigated. We found that high test reliability did not necessarily lead to small variances or covariances. For a new subject, higher test reliability led to larger predicted variances and covariances, because high test reliability enabled a more accurate prediction of test score variances. Regarding a new subject taking a new test, in this study, higher test reliability led to a large variance when the sample size was smaller than half the number of tests. The classical test theory is reanalyzed from the viewpoint of predictions and some suggestions are made.     

Bayesian estimation of a multilevel IRT model using gibbs sampling

In this article, a two-level regression model is imposed on the ability parameters in an item response theory (IRT) model. The advantage of using latent rather than observed scores as dependent variables of a multilevel model is that it offers the possibility of separating the influence of item difficulty and ability level and modeling response variation and measurement error. Another advantage is that, contrary to observed scores, latent scores are test-independent, which offers the possibility of using results from different tests in one analysis where the parameters of the IRT model and the multilevel model can be concurrently estimated. The two-parameter normal ogive model is used for the IRT measurement model. It will be shown that the parameters of the two-parameter normal ogive model and the multilevel model can be estimated in a Bayesian framework using Gibbs sampling. Examples using simulated and real data are given.     

Go/No-Go范式中非反应手状态对Simon效应性质的影响

为了探讨非反应手对标准Simon任务改装的go/no-go任务的影响,被试只对其中一种颜色进行按键反应,通过指导语来操控非反应手的状态,结果发现：(1)实验一中当不提醒非反应手如何放置时,不会产生Simon效应;(2) 实验二中要求非反应手放在固定的桌面位置上,产生了视觉运动Simon效应,其随反应时的增大而减小;(3) 实验三中要求非反应手放在固定的非反应键上,却产生了认知Simon效应,其随反应时的增大而增大。这说明非反应手的状态影响Simon效应的产生及其性质。     

职业使命感与免费师范生学业投入的影响：基于社会认知职业理论的视角

本研究以436名师范生为研究对象,采取社会认知职业理论（SCCT）为理论分析视角探讨了职业使命感对大学生学业投入的影响及其内在机制。结果表明：（1）职业使命感可以显著提高师范生的学业投入度;（2）职业结果期待和职业自我效能在职业使命感与学业投入之间起到部分中介作用;（3）职业使命感还可以通过职业结果期待、职业自我效能影响职业满意度,进而影响大学生的学业投入。最后,本研究对实践意义和研究局限进行了讨论。     

2~3岁儿童在分配情境下的公平敏感性

公平敏感性是指个体对感知到的公平和不公平的稳定而个性化的反应, 其表现为个体对公平的不同偏好。本研究旨在考察2~3岁儿童公平敏感性发展特点, 并进一步探究分配情境、分配数量和分配结果等因素对儿童公平敏感性的影响。实验1采用VOE范式, 在第三方任务情境下, 考察130名2~3岁儿童公平敏感性的发展特点, 结果发现在VOE范式下, 2~3岁儿童公平敏感性随着年龄增长而上升, 3岁~3岁3个月儿童的公平敏感性发展最明显。实验2, 选取60名处于公平敏感性发展最明显的3岁~3岁3个月的儿童比较其在不同分配情境、分配数量以及分配结果下的注视时间差异。结果表明, 在有接受者情境下儿童公平敏感性显著高于无接受者情境下的公平敏感性, 并且公平敏感性受分配数量的影响。     

免费师范生的成就动机与职业兴趣相关研究

该研究以陕西师范大学的1349名大学生为样本,将成就动机的三个因素和职业兴趣六个因素综合起来加以考察,以揭示免费师范生的成就动机与职业兴趣之间的内在关系。结果表明：（1）免费师范生的成就动机水平低于大学生平均水平。非免费师范生的避免动机水平依次高于免费师范生和非师范生。（2）免费师范生的成就动机存在专业差异,职业兴趣存在性别和专业显著。（3）免费师范生的追求成功动机与职业兴趣的六个类型呈正相关,避免失败的动机与探索型、社会型和管理型星负相关。回归分析发现,追求成功和合成动机能够正向的预测社会型的职业兴趣。     

Modeling Information Content Via Dirichlet-Multinomial Regression Analysis

Shannon entropy is being increasingly used in biomedical research as an index of complexity and information content in sequences of symbols, e.g. languages, amino acid sequences, DNA methylation patterns and animal vocalizations. Yet, distributional properties of information entropy as a random variable have seldom been the object of study, leading to researchers mainly using linear models or simulation-based analytical approach to assess differences in information content, when entropy is measured repeatedly in different experimental conditions. Here a method to perform inference on entropy in such conditions is proposed. Building on results coming from studies in the field of Bayesian entropy estimation, a symmetric Dirichlet-multinomial regression model, able to deal efficiently with the issue of mean entropy estimation, is formulated. Through a simulation study the model is shown to outperform linear modeling in a vast range of scenarios and to have promising statistical properties. As a practical example, the method is applied to a data set coming from a real experiment on animal communication.     

Daily variations in attachment anxiety and avoidance: A density distributions approach

Attachment theory proposes that experiences of acceptance and rejection will modify feelings of attachment security, but such processes have rarely been investigated. In this study, daily variations in attachment anxiety and avoidance were investigated across 7 days in a sample of college undergraduates currently in romantic relationships. We observed significant within-person variation in attachment avoidance and anxiety. Participants reported lower anxiety and avoidance on days on which they felt more accepted by their romantic partners. Further, perceptions of acceptance predicted the following day’s attachment security through lower negative mood. Greater variability in attachment avoidance and anxiety was associated with greater physical aggression in relationships.     

More transparency of world view assumptions: Commentary on “Psychiatry and religion: Consensus reached!” (Verhagen, 2017)

ABSTRACT

The commentary compares the WPA position statement with a similar paper published recently by the German Association for Psychiatry, Psychotherapy and Psychosomatics (DGPPN; Deutsche Gesellschaft für Psychiatrie, Psychotherapie und Nervenheilkunde). These papers should be a starting point to foster R/S studies within the bio-psycho-social-spiritual framework, a thoughtful discernment of the psycho-spiritual mixture and more training opportunities for therapists to better integrate the spiritual dimension into treatment.
