视觉恐惧加工的神经通路

对危险信号的快速警觉具有生物学意义,研究发现视觉恐惧信号可以经过两条不同的通路传达杏仁核:一条直接的皮层下通路,另一条是间接的视觉皮层通路.最近三年(2004-2006)一批脑成像和电生理研究对此进行了深入探讨.本文以此为基础对两条通路的主要神经结构,神经传递的先后过程以及它们间的关系进行了详细的综述.     

心理咨询与治疗研究中的质性研究

心理咨询与治疗研究与实践长期存在脱节现象;心理咨询与治疗研究需要研究方法的多元化与科学化.质性研究方法的应用能在一定程度上解决心理咨询与治疗领域所面临的这两个问题.本文对质性研究方法应用于心理咨询与治疗研究的背景和现状进行综述,以期能对国内心理咨询与治疗研究者提供思考和借鉴.     

抑郁倾向的绘画诊断研究

通过问卷、绘画测验和回归分析,8项绘画特征被验证能够有效反映神经症抑郁倾向.根据这些绘画特征建立的回归方程经检验具有中等的解释效果.同时,评分者一致性程度较高.研究结果表明,通过"房子树人绘画测验",能够建立对神经症抑郁倾向进行有效测量的临床诊断工具.     

多种感觉信息整合的认知与神经机制研究

我们通常利用多种感觉通道的信息对周围世界进行感知,如视觉、听觉、嗅觉、前庭感觉和本体感觉信息.为了确保对环境的正确感知,大脑必须把对同一物体特征进行表征的不同感觉信息整合成一致的、稳定的信息.以往的研究证实不同感觉信息之间是以统计最优化的模式结合的.文章首先综述了在贝叶斯理论的基础上建立起来的统计最优化模型以及其行为实验验证方法.然后,介绍了相关的神经成像研究结果和具有生理意义的神经网络模型.     

认知负荷对顿悟问题解决的影响

顿悟问题解决有许多影响因素,其中认知资源的耗费会影响到工作记忆的容量及加工效果,进而影响顿悟问题解决的效果.本实验通过三种呈现时间间隔,两种活动任务(高负荷任务和低负荷任务),组合为五种实验条件,探讨了源问题与靶问题呈现时间间隔与间隔期间活动任务(即不同的认知资源耗费程度)对关键启发信息激活的影响.结果表明:认知资源的耗费是影响顿悟问题解决的重要因素,认知资源耗费越多,关键启发信息越难激活;如果没有其他信息的干扰,源靶问题之间的时间问隔越长,有助于被试对源问题中的关键启发信息的思考与归纳,进而在解答靶问题过程中就越容易提取出关键启发信息.     

马基雅维里道德观的再认识

在对马基雅维里道德观的评价上,学界历来存在着误解和分歧.马基雅维里思想中的道德观部分固然有缺陷,但据此把它指责为道德败坏和邪恶的"马基雅维里主义",则是一种建立在误解基础上的偏见.本文依据对马基雅维里赖以形成其道德观的时代背景、自身经历和其著作的综合研究,尝试厘清这种误解和偏见,就马氏的具有开创意义的现实主义道德观进行再认识.     

小学青年教师社会支持与心理健康的相关研究

目的:探讨小学青年教师社会支持与心理健康之间的关系。方法:采用社会支持评定量表(SSRS)与症状自评量表(SCL-90),对296名小学青年教师进行心理健康、社会支持及其相关调查。结果:发现(1)SCL-90各个因子上小学青年男女教师均无显著差异。(2)在支持利用度得分平均数方面男教师低于女教师,差异达到极其显著的水平(P<0.01)。(3)支持总分的平均得分上男教师也显著低于女教师(P<0.05)。结论:小学青年教师的社会支持与其心理健康水平成正相关,不完善的社会支持与其心理健康水平成负相关。     

Influence analysis for the factor analysis model with ranking data

Influence analysis is an important component of data analysis, and the local influence approach has been widely applied to many statistical models to identify influential observations and assess minor model perturbations since the pioneering work of Cook (1986) . The approach is often adopted to develop influence analysis procedures for factor analysis models with ranking data. However, as this well‐known approach is based on the observed data likelihood, which involves multidimensional integrals, directly applying it to develop influence analysis procedures for the factor analysis models with ranking data is difficult. To address this difficulty, a Monte Carlo expectation and maximization algorithm (MCEM) is used to obtain the maximum‐likelihood estimate of the model parameters, and measures for influence analysis on the basis of the conditional expectation of the complete data log likelihood at the E‐step of the MCEM algorithm are then obtained. Very little additional computation is needed to compute the influence measures, because it is possible to make use of the by‐products of the estimation procedure. Influence measures that are based on several typical perturbation schemes are discussed in detail, and the proposed method is illustrated with two real examples and an artificial example.     

Predicting Marital Satisfaction From Self,Partner, and Couple Characteristics: Is It Me,You, or Us?

Past research on the link between personal characteristics and marital satisfaction has taken either an individual or a dyadic approach. The individual approach examines how self and/or partner characteristics are associated with satisfaction, whereas the dyadic approach focuses on couple characteristics such as couple similarity. The current research was designed to integrate both approaches. A modified Actor-Partner Interdependence Model (Kashy & Kenny, 2000) was proposed to test simultaneously the contributions of self characteristics, partner characteristics, and two types of couple similarity (level similarity measured by the absolute difference score and shape similarity measured by the profile correlation) in predicting husbands' and wives' marital satisfaction. This model was tested by structural equation modeling in two large, nationally representative, urban samples (N=536 and 537 couples) from China. The results were largely replicated across four personality domains and two value domains, suggesting that all predictors tended to make independent contributions to satisfaction except the absolute difference score.     

论犹太人成功的文化机制

犹太人在人类实践领域的成功是显著的,除了社会的环境和特殊的历史经历、遗传的因素外,文化的因素也起着重要作用.在导致犹太人成功的思想信念中,重要的有修补世界、特选子民、金子是好、为我-利他等观念.
