调节效应与中介效应的比较和应用

讨论了调节变量的概念和调节效应分析方法,并简要介绍了中介变量的概念和中介效应分析方法。从研究目的、关联概念、典型模型、变量的位置和功能、效应的估计和检验方法等角度,对调节变量和中介变量、调节效应和中介效应以及相应的模型做了系统的比较。作为应用例子,在儿童行为对同伴关系的影响研究中分析和比较了调节变量和中介变量。     

自伤行为的神经生理机制及共病障碍比较

自伤行为是危害公众心理健康的重大隐患。综合自伤行为的新近研究成果,情绪脑区、控制脑区、疼痛脑区、奖赏脑区、阿片类系统和多巴胺系统以及特定基因的异常共同参与了自伤行为。将自伤行为与自杀、成瘾、进食障碍和抑郁障碍进行比较,发现自伤行为与其共病障碍存在部分相似的发生机制。在此基础上尝试构建了自伤行为的认知神经机制假设模型,并就自伤行为神经生理机制的性别差异、发展特点及干预等提出研究展望。     

An n-Player Semantic Game for an n + 1-Valued Logic

First we show that the classical two-player semantic game actually corresponds to a three-valued logic. Then we generalize this result and give an n-player semantic game for an n + 1-valued logic with n binary connectives, each associated with a player. We prove that player i has a winning strategy in game if and only if the truth value of is t _i in the model M, for 1 ≤ i ≤ n; and none of the players has a winning strategy in if and only if the truth value of is t ₀ in M.     

基于双眼视差的立体视觉去掩蔽效应

基于双眼视差的立体视觉不改变目标与掩蔽刺激之间的信噪比, 但能使不同的刺激被知觉在不同的深度位置上以降低目标信号所受到的掩蔽作用。本综述在总结前人双眼去掩蔽研究的基础上, 强调深度维度上的视觉注意在这种主观空间分离去掩蔽过程中所起的重要作用, 并介绍了双眼去掩蔽在现代科技领域中的典型性应用。最后, 结合听觉主观空间分离去掩蔽的研究进展, 本综述认为主观空间分离去掩蔽是大脑处理复杂刺激场景的一个基本功能。     

嗅知觉及其与情绪系统的交互

在人类的各种感觉通道中, 嗅觉尤其和情绪有着千丝万缕的联系。两者在种系发生进程中存在一定的亲缘关系, 在解剖结构上也高度重叠。气味天然带有情绪效价, 不管是在意识上还是意识下层面, 非社会性和社会性嗅觉信息都能对情绪产生影响, 反之情绪也能对嗅知觉产生作用。已有的神经影像研究显示嗅觉和情绪系统加工均涉及杏仁核、海马、脑岛以及眶额皮层等区域。与此同时, 非社会性和社会性嗅觉信息的编码和它们对情绪系统的作用方式也不尽相同。     

心理辅导三大理论之人性观之剖析

人性观是对人的基本看法和哲学假设,在心理咨询和资料中,人性观是一切方法和技术的理论基础。在回答什么是人性和人性观的基础上,总结出人性观所应回答的基本问题,依据精神分析、行为主义和人本主义三大辅导流派对人性观基本问题所作的回答,剖析了三大流派的人性观。     

A Propositional Logic with Relative Identity Connective and a Partial Solution to the Paradox of Analysis

We construct a a system PLRI which is the classical propositional logic supplied with a ternary construction , interpreted as the intensional identity of statements and in the context . PLRI is a refinement of Roman Suszko’s sentential calculus with identity (SCI) whose identity connective is a binary one. We provide a Hilbert-style axiomatization of this logic and prove its soundness and completeness with respect to some algebraic models. We also show that PLRI can be used to give a partial solution to the paradox of analysis. Presented by Jacek Malinowski     

6～11岁儿童执行功能发展研究

以168名6~11岁儿童为被试,使用9种执行功能任务研究了儿童三种执行功能成分的发展,三种执行功能是,抑制(Inhibition)、转换(Shifting)和刷新(Updating),结果发现:整个儿童阶段,三种执行功能一直表现出随年龄递增而增长的趋势;不同的执行功能表现出不同的发展速率,其中抑制控制大约在6~7岁表现出一个快速的增长期,记忆刷新从7岁到10岁一直呈线性增长,转换表现出两个快速增长期,第一个快速增长则发生在7~8岁之间,第二个快速增长则发生在9-10岁之间,三种执行功能的发展趋势到大约10岁后趋于平缓,10岁和11岁儿童的表现没有显著性差异;所有执行功能任务测量中没有发现性别主效应,年龄和性别的交互作用不显著。     

Trait anxiety modulates supraliminal and subliminal threat: Brain potential evidence for early and late processing influences

Analysis of threat is thought to involve a “quick and dirty” stage in conjunction with slower processing that is more complete. We investigated both types of threat analysis by recording brain potentials in response to threat and neutral words. Personality testing was used to identify participants who were either high or low in trait anxiety (TA). An observed enhancement of occipital P1 potentials to threat words during an emotional Stroop task was interpreted as a signal of unconscious processing, since it was early, independent of whether word exposure was subliminal or supraliminal, and more prominent the higher the level of TA. Later positive potentials were also enhanced for threat versus neutral words, but the amplitude enhancement increased with higher TA only in the subliminal condition. These results suggest that unconscious analysis of threat is intensified in those prone to anxiety, as is a later stage of threat processing subject to dynamic interactions between automatic and strategic influences.     

3~5岁儿童气质活动性与父母教养方式的关系

采用实验室观察和问卷法考察3~5岁儿童气质活动性与父母教养方式之间的关系。结果发现：（1）3~5岁儿童气质活动性与父母教养方式之间存在相互关系。不同活动性儿童的父母在溺爱性和放任性上有显著差异。（2）父母对3~5岁不同活动性儿童的教养方式存在性别差异。3~5岁不同活动性的男孩其父母的教养方式没有差异。而3~5岁不同活动性女孩其父母教养方式在溺爱性和放任性上差异显著。
