Social Dominance Orientation, Hierarchy Attenuators and Hierarchy Enhancers: Social Dominance Theory and the Criminal Justice System

This study investigated differences in social dominance orientation between incumbents of different social roles (police officers vs. public defenders) and ethnic groups known to differ in general social status (i.e., whites vs. blacks and Hispanics). Consistent with theoretical expectations: (a) Police were significantly more social-dominance oriented than either jurors or public defenders. (b) Public defenders tended to be less social-dominance oriented than jurors. (c) Euro-Americans were significantly more social dominance oriented than Afro- and Hispanic-Americans, (d) Euro-American police officers had, by far, the highest levels of social dominance orientation. Furthermore, all of the effects above held even when controlling for demographic factors such as gender, social class, age, education, and ethnic group. The theoretical implications of these findings are discussed.     

杏仁复合体损毁对大鼠空间认知能力的影响

杏仁复合体损毁大鼠Ｍｏｒｒｉｓ迷宫作业学习成绩显著低于控制组,记忆成绩较显著低于控制组。其搜索目标时主要采用与控制组的图式策略相异的趋向式策略。策略差异提示：杏仁复合体参与大鼠空间认知的辅助加工。     

护士职业的人格特质研究

采用Ｙ－Ｇ性格测验问卷,对临床护士和在读护生共３９０人,进行了心理测评,展开了护士职业的人格特质研究。研究结果表明：优秀护士群体的性格类型和某些人格特质显著地优于一般护士群体;优秀护士与一般护士间所显现出显著差异的人格特质,对于护士角色人格的构成具有决定性影响;Ｙ－Ｇ性格测验的Ａ型性格类型评定对于护士职业的心理选拔显现特异性趋势;整个测评研究结果,基本支持＂护士个体人格特质与角色人格特质的匹配模式＂等理论假设．     

缺陷儿童人格诊断量表的修订

缺陷儿童人格诊断量表是日本特殊教育领域的一种专门用于测量缺陷儿童人格的著名量表。作者用三年时间对其进行了修订,建立了包括弱智、聋哑、盲等缺陷儿童的中国常模。该量表具有较高的信度与效度,是一个较好的心理测量工具。     

恐惧发生与预防的实验研究：──Ⅱ、强噪音下不同处理背景动物身心变化的观察分析

采用生理心理学的实验方法．对强噪音下四组不同处理背景大鼠的旷场反应、援食、饮水、排泄和尿生物化学等方面进行比较。结果发现：①Ⅰ组（强刺激组）的各类指标均发生情绪性（恐惧）改变。与２组（预防训练Ⅰ组）、３组（预防训练Ⅱ组）、４组（控制组）以及自身基线（ＭＡＯ）比较差异显著;②适应性训练有助于防止大鼠恐惧发生及上述各类指标发生异常．③由于训练的方法不同,预防的效果也不同。３组与４组比较无显著差异,２组与４组比较某些指标有显著差异。④１组和２组部分大鼠出现皮肤、消化道病变。     

Misalignment effects in 3-D versions of Poggendorff displays

Strong misalignment effects are found in three-dimensional (3-D) versions of Poggendorff displays viewed binocularly. The components of the standard 2-D Poggendorff figure—the parallels and the oblique segments—were presented in 3-D depth as a flat rectangular object with occluding edges and an oblique line situated behind the object. Three experiments investigated the misalignment effects under three different observation instructions: Subjects were told to look at the oblique (Experiment 1), at the rectangle (Experiment 2), or at the background (Experiment 3). Experiments 1 and 2 examined the effects on judgments of alignment of varying the distance in depth that separates the oblique from the rectangle. Experiment 3 examined the effects of varying the distance between the fixated background and the 3-D Poggendorff figure. Both standard and reversed misalignment effects were obtained. When the viewing condition produces crossed disparity for the oblique, perceived misalignment occurs in the usual Poggendorff direction, but it is reversed with uncrossed disparity. Moreover, the amount of misalignment is related to the amount of disparity, and it can be much stronger than is usual in the 2-D versions of the Poggendorff. The misalignment effects can be explained by binocular integration to produce a single cyclopean image.     

成人脑涨落图年龄变化特点的研究

该工作研究了１２０名２０－７９岁正常成人脑涨落图的年龄变化特点。结果表明：（１）从２０岁到５０岁,Ｓ系谱线活动向低频方向集中,６０岁后谱线又向高频方向有所移动;（２）部分谐振系的随龄变化表现明显,其中以Ｓ１７系变化最为敏感;（３）脑区间相干活动和各脑区的连频活动随年龄增强,脑能量分布的有序性逐渐破坏;（４）增龄性变化主要反映在优势脑区（左前脑）和优势脑轴（左前／右后脑）上,与脑高级机能活动密切相关的左前脑的退行性变化最为明显。上述结果反映了脑功能的减退是一个非线性的多层次的复杂过程。     

编码方式对汉字短时记忆提取的影响

短时记忆提取是认知心理学研究中的重要课题之一。自Sternberg(1 966)提出短时记忆提取作的是序列的从头到尾的完全搜索以来 ,许多研究者对短时记忆提取进行了广泛的研究 ,提出了序列的自动停止的搜索、平行加工、直接存取 ,以及序列搜索和直接存取双重模型等许多不同看法 ,引起了激烈争论。本研究的目的是试图探索编码方式对汉字短时记忆提取的影响。实验运用Sternberg的“探测法” ,以随机排列的汉字作识记组和探测项刺激。实验结果表明 :编码方式对汉字短时记忆提取有很大影响 ,当用声音编码方式提取短时记忆汉字时 ,被试倾向于从头到尾的完全的搜索 ;当用形状编码时 ,被试倾向于作自动停止的搜索。     

智力落后儿童人格特性的研究

智力落后儿童由于大脑功能发育障碍,在个性的成熟和发展方面受到一定限制,表现出与正常儿童不同的个性特征。在不同智残程度的儿童中也存在着个性差异。智力与个性发展有密切关系,脑功能受损越严重,对个性发展的影响也就越明显。     

关于听觉条件下中文字词劣效果的研究

对听觉条件下中文字词劣效果的问题进行了实验考察,结果发现：在文章听点作业中,被试对高、低频目标字词语音的正误判断量存在着显著性差别,前者较后者成绩差,表现出字词劣效果的现象;在单字词的听点作业中,未发现被试对高、低频目标字词语音正误判断量方面的显著性差别;无论在文章还是单字词的听点作业中,被试对高、低频目标字词语音的正误判断量均比较低下,表明语音知觉的范畴性特征对字词语音的辩认准确性具有较大影响。
