阳明学与袁宗道的“四书”诠释

公安派的重要代表人物之一袁宗道诠释“四书” ,显示了学宗阳明的取向 ,具有与儒林学人论学不尽相同的特色。袁宗道诠释“四书”与王门主意派形似而与王门现成派实同。宗道诠释“四书”是公安派中惟一系统解说儒家经典的著作。宗道通过提升意念 ,为公安派自然抒写性情提供了重要的理论依凭。     

Likert量表分析中不同IRT模型的有效性

5级Likert量表可直接分析,也可以转化为3级评分,或转化为2级评分。前二者可以采用等级IRT模型,后者可以采用2级IRT模型。研究表明2级IRT模型中的2参数模型是最适合的模型。多级评分模型与数据拟合也很好,而且等级越多测量精度越大。     

国内外关于心理战研究的现状和问题

心理战作为一种战争和社会的实践活动,有着悠久的历史,但作为一门独立学科,发端于上世纪初。该文概述了心理战作为一个独立研究领域以来国内外关于心理战研究的现状。在此基础上,提出了心理战研究存在的问题和不足,最后对我国心理战研究的发展方向提出了看法。     

5～16岁儿童对中国人形象的评价与喜好研究

采用个别访谈和问卷法,调查531名5—16岁中国儿童心目中的“中国人”形象以及儿童对中国人身份的喜欢程度和发展趋势。结果表明：(1)总体而言,被调查的5—16岁中国儿童对中国人持积极评价,对自己是一名中国人有积极的情感体验。(2)不同年龄的儿童对中国人形象的积极评价先上升后下降,随后有所回升,其中9—10岁儿童的评价最为积极。(3)儿童对中国人身份的喜欢程度随年龄的增长而下降。(4)对5—10岁的年幼儿童来说,对中国人的评价与喜欢成为中国人的关系不大,11—16岁的年长儿童则能更加紧密地联系两者。     

自闭症幼儿的视觉性自我认知实验研究

通过对平均心理年龄为23个月的6名自闭症幼儿的实验研究．甄别他们是否能从视觉上进行自我与他人的分化认知并进一步探索自闭症幼儿对镜像自我认知与录像自我认知上的差异;以秒为单位．对实验结果和过程进行了编码分析。结果表明：这6名幼儿在看自己的录像时,比看同伴的表现出更多的关注和喜悦;对录像的自我进行认知寸表现出更大的关注和积极情绪。由此推断他们已具有初步的自我认知。     

亲子支持对老年人主观幸福感的影响机制

采用自编的“老年人亲子支持问卷”、“老年人恩情感问卷”和已有量表,对来自4个省市的288名53-87岁的老年人进行问卷调查。结果表明,亲子支持通过影响老年人的自尊感、孤独感、恩情感,进而影响其主观幸福感。其中接受支持对自尊感、孤独感、恩情感产生积极的影响效应;给予支持对老年人的自尊感产生积极的影响效应。     

童年中期同伴侵害影响孤独感的中介变量分析

为检验同伴侵害影响儿童孤独感的中介变量,采用同伴提名、儿童自我知觉量表、儿童孤独感量表和班级戏剧问卷对武汉市某小学3-6年级445名儿童进行了调查。结果发现：同伴接纳和整体自尊是同伴侵害与孤独感间的两个中介变量。 在考察单一变量的中介作用时,同伴接纳在儿童的同伴侵害与其孤独感间起完全中介作用,而整体自尊在儿童的同伴侵害与其孤独感间起部分中介作用;当同时考察同伴接纳与整体自尊的中介作用时,同伴接纳与整体自尊在同伴侵害与孤独感间起完全中介作用,而且,由于同伴接纳对整体自尊的正向预测作用,同伴侵害对整体自尊的预测关系不显著。     

General belief in a just world and resilience: Evidence from a collectivistic culture

Previous research showed that in the individualistic culture, adults endorse the personal more than the general belief in a just world (PBJW vs. GBJW). Comparatively little is known about the prevalence character and adaptive functions of GBJW, especially in the collectivistic culture. We conducted three surveys among the Chinese adults and adolescents. We found that (1) Chinese adults and adolescents endorsed more GBJW than PBJW; (2) Adult survivors with high exposure to post‐earthquake trauma and adolescents in the poverty‐stricken area maintained high GBJW, with relatively lower PBJW. (3) GBJW predicted the psychological resilience in all the three samples independent of PBJW. The results imply that in contrast to populations from the individualistic culture, people from the collectivistic culture endorse a robust GBJW, which allows them to resiliently confront harsh realities.

Phonological abstraction in processing lexical-tone variation: evidence from a learning paradigm

There is a growing consensus that the mental lexicon contains both abstract and word-specific acoustic information. To investigate their relative importance for word recognition, we tested to what extent perceptual learning is word specific or generalizable to other words. In an exposure phase, participants were divided into two groups; each group was semantically biased to interpret an ambiguous Mandarin tone contour as either tone1 or tone2. In a subsequent test phase, the perception of ambiguous contours was dependent on the exposure phase: Participants who heard ambiguous contours as tone1 during exposure were more likely to perceive ambiguous contours as tone1 than participants who heard ambiguous contours as tone2 during exposure. This learning effect was only slightly larger for previously encountered than for not previously encountered words. The results speak for an architecture with prelexical analysis of phonological categories to achieve both lexical access and episodic storage of exemplars.
