客体特征统计属性表征机制的特异性

通过两个实验就视觉系统能否像计算平均数那样高效地计算其他统计量的问题进行了探讨。实验—保持—组圆的平均大小不变而改变众数,考察平均数估计是否受众数变化的影响;实验二采用与实验一相同的刺激,直接考察被试估计众数的绩效。结果发现：（1）对平均数的估计不受总体众数变化的影响;（2）对众数的估计往往不如对平均数的估计准确,估计值受平均数变化的影响;（3）在估计众数的任务中,被试成绩受总体极大值的影响。上述结果表明,视觉系统不存在针对众数的自动化加工机制。根据本实验的结果可以进一步推测,视觉系统并非对所有统计量都可做高效加工,而可能存在针对平均数的特异加工机制。     

选择性注意中意识与无意识过程分离的实验研究

以汉语单字词为材料,通过颜色来区分目标和分心物,采用过程分离程序,直接探讨了目标激活与分心物抑制和意识、无意识过程之间的关系。结果表明,（１）靶词充当分心物时,不仅意识过程存在的概率降低,无意识过程存在的概率也降低。这一结果说明,在选择性注意任务中,信息是有关还是无关,并不能分离意识和无意识过程;（２）靶词充当目标时,加工水平影响Ｐｃ,但不影响Ｐｕ,而靶词充当分心物时,加工水平既不影响Ｐｃ,也不影响Ｐｕ。因此,加工水平能否分离意识和无意识过程,依赖于靶词的作用或信息是否有关     

An improved stochastic EM algorithm for large-scale full-information item factor analysis

In this paper, we explore the use of the stochastic EM algorithm (Celeux & Diebolt (1985) Computational Statistics Quarterly, 2, 73) for large-scale full-information item factor analysis. Innovations have been made on its implementation, including an adaptive-rejection-based Gibbs sampler for the stochastic E step, a proximal gradient descent algorithm for the optimization in the M step, and diagnostic procedures for determining the burn-in size and the stopping of the algorithm. These developments are based on the theoretical results of Nielsen (2000, Bernoulli, 6, 457), as well as advanced sampling and optimization techniques. The proposed algorithm is computationally efficient and virtually tuning-free, making it scalable to large-scale data with many latent traits (e.g. more than five latent traits) and easy to use for practitioners. Standard errors of parameter estimation are also obtained based on the missing-information identity (Louis, 1982, Journal of the Royal Statistical Society, Series B, 44, 226). The performance of the algorithm is evaluated through simulation studies and an application to the analysis of the IPIP-NEO personality inventory. Extensions of the proposed algorithm to other latent variable models are discussed.     

How mindfulness affects benign and malicious envy from the perspective of the mindfulness reperceiving model

At present, mindfulness is a hotspot in psychological research. Mindfulness is an effective tool that enables people to effectively inhibit negative emotions. Previous studies have shown that envy is a typical negative emotion; however, envy can be divided into two completely different types: benign envy and malicious envy. The question then arises, how does mindfulness affect both types of envy? Using a mindfulness reperceiving model, we explored the effect of mindfulness on these two different types of envy and on the mediating mechanism of psychological resilience. To accomplish this, we recruited 676 Chinese undergraduates to complete the Mindful Attention Awareness Scale (MAAS), the Benign and Malicious Envy Scale (BEMAS) and the Connor-Davidson Resilience Scale (CD-RISC). The results we obtained showed that mindfulness and psychological resilience significantly and negatively predicted malicious envy and that psychological resilience played a partially mediating role in the relationship. In addition, the results showed that there was no significant effect between mindfulness and benign envy; however, psychological resilience can significantly and positively predict benign envy and played a completely mediating role between mindfulness and benign envy. These results effectively extend theories based on the mindfulness reperceiving model while also being important for promoting benign envy and inhibiting malicious envy in terms of improving mindfulness and psychological resilience.     

Shavinina的智能测评观述评

近来Shavinina等人通过一系列研究,提出了一种新的智能结构观,认为智能主要包含两个部分：认知经验和智能表现。在此基础上,他们分析了未来智能测验应遵循的一系列原则,并进行了初步的测验编制尝试,提出了一些富有创意的测验方法,如“完美计算机”、“概念整合”以及“问题建构”等测验。Shavinina等人所提出的新智能观以及关于智能测验的新技术具有很强的启发性,代表了智能研究的又一新方向。

大学生心理压力应对方式特点的研究

本研究采用自编的大学生压力应对方式闯卷,考察了全国各地2007名大学生心理压力应对方式的特点。结果表明：(1)大学生压力应对方式问卷具有良好的内容效度和预测能力,内部一致性和测量稳定性理想;(2)大学生的压力应对方式总体上以心理调节机制为主,自我防御和外部疏导机制使用较少;(3)在压力的应对方式上,大一学生以外部求助、压抑、幻想和调整情绪方式为主,大二、大三学生以自我防御方式和总结经验为主,大四学生则较多采用心理调节机制的方式;(4)女生的应对方式比男生更积极,农村来源的大学生倾向于压抑自己和总结经验,城市来源的学生更喜欢宣泄压力,独生子女的应对方式以消极防御机制居多。     

返回抑制对工作记忆储存和目标维持的影响

将线索一靶子范式和N—Back变式结合,以工作记忆的记忆错误和侵入错误数为指标,探讨了返回抑制与工作记忆的储存和加工之间的关系,并对返回抑制的机制进行了深入探讨。结果表明,当记忆项目出现在线索化位置时,两种错误数均显著高于出现于非线索化位置的情况,但侵入错误的抑制效应只出现于长SOA条件。这揭示了返回抑制既影响工作记忆的储存又影响对任务目标的维持,也为返回抑制的注意说提供了新证据。     

两种世界观影响下的生涯咨询评估

自上世纪初逻辑实证主义影响下量的评估就一直在生涯咨询中占主导地位。近年来建构主义对生涯咨询的影响逐渐增加．质的评估越来越突出。文章立足于两种不同的世界观基础,比较了量和质的生涯评估模式及其特征,并探讨如何发展质的生涯评估过程。
