Scene layout from ground contact,occlusion, and motion parallax

An important factor in determining perceived scene layout is optical contact between objects and the ground surface (“ground contact”). The relation between ground contact and occlusion was investigated in four experiments with stationary and motion parallax scenes containing a pole that occluded or was occluded by one or more cylinders. Some judgements were inconsistent with occlusion in stationary scenes, but judgements were consistent with occlusion in motion parallax scenes. When the range of object positions consistent with occlusion did not include the positions specified by ground contract or by motion parallax, the ground contact and motion parallax information still had a quantitative effect on the perceived position of the object within the range consistent with occlusion. These results demonstrate a cooperative interaction between ground contact, occlusion, and motion parallax in determining perceived layout in 3-D scenes.     

情绪性工作记忆对选择性注意的影响

选取大学本科生33名,采用情绪启动范式与再认范式相结合,要求被试依次完成情绪词识记、目标面孔性别判断及情绪词再认任务,探讨保存于工作记忆中的情绪性刺激对面孔性别判断任务的影响。结果显示:(1)在中性和恐惧情绪启动刺激条件下,被试对目标面孔性别判断的反应时要显著长于悲伤条件。(2)在愉悦情绪启动词条件下,线索提示有效性差异显著;在无效线索提示条件下,启动刺激的不同情绪效价差异显著。(3)对情绪面孔性别与被试性别一致性/非一致性两种条件下反应时对比发现,男、女被试在情绪面孔性别判断任务中均表现出异性相吸效应。综上所述,保存在工作记忆中情绪刺激会对面孔性别的识别产生自上而下的影响。     

汉字形码和音码的整体性对部件识别的影响

本实验从分析汉字整体知觉的具体表现形式入手,通过三个实验探讨字的整体知觉对部件知觉的影响。实验一以分解方式为变量,考查字形整体知觉对部件识别的影响,发现识别不同结构的字的部件之活动受知觉分解路线(如顺读或逆读)的影响。作者认为这种分解方式效应很可能跟部位有关。实验二证实了这一分析,并进而认为部位效应又跟部位与字形整体知觉的紧密程度有关。实验三以语音码为变量,发现成字部件的字音与整体字语音一致者(形声字),其分解知觉成绩比不一致者(非形声字)有明显的优势。这意味着,整体字音知觉的单一性对部件知觉的作用。最后,本研究还考查了部件识别法的有效性,并认为在研究知觉的整体与部分关系问题时,该法不失为一种新的实验范型。     

影响视觉复合刺激中整体和局部性质加工的几种因素

文章研究了视知觉组织,空间位置不确定性和视野位置等因素对复合刺激中整体和局部性质加工的影响。实验发现,（１）当复合刺激呈现在白背景上时,反应时和干扰作用都表明复复合刺激中大图的加工优于小图,刺激位置的不确定削弱大图对小图的干扰作用;而当复合刺激呈现在由“＋”组成的背影或时,小图的加工优于大图,刺激位置的不确定延长分辩小图的ＲＴ;（２）与周国刺激相比,分辨视野中央的复合刺激的ＲＴ较短,这种影响对分辨     

在押毒品犯人格的基本特征及其相关因素的研究

本研究以 3 78名在押毒品犯为被试 ,以CPI为测量工具 ,探讨了在押毒品犯的基本特征和类型特征 ,并采用方差分析技术研究了影响毒品犯人格的若干因素。结果发现 ,与对照组相比 ,在押毒品犯除了在“自我控制”分量表上未发现显著差异外 ,其余的 1 9个分量表上均有显著差异 ;在押毒品犯在四种人格类型上的分布不平衡 ,主要集中在Delta类型 ;年龄、关押时间对毒品犯的人格特征的变异有一定影响 ,而减刑次数的影响不显著     

沟通、意义和组织化行动研究

组织化行动对组织发展和学习意义很大。有一种观点认为,组织化行动由成员之间的共识而引发;但又有另一种观点认为组织化行为产生的基础在于交换而不在于共识。本研究试图综合以上两种看法,指出等效型意义能够带来组织化或集体性行为。有效的沟通机制能够创造维持等效型意义。     

Transformation of Miller indices in twinned structures

Abstract

The parent–twin transformation equations derived by Mügge and subsequent workers have been reinvestigated in view of the observation that these equations produce similar, but not numerically identical, transformations. The current study suggests that, from the point of view of the classical orientation relations, the assumptions made in several derivations are applicable only to special transformation situations.     

汉字属性匹配与大脑两半球协同活动

在识别汉字时,大脑两半球同时加工的作业成绩是否随加工阶段的增加而显出优势。本研究用汉字形、音、义三种属性分别相匹配的方法用用指定指定提取法,所得实验结果一致表明,形似材料双侧视野同时识别与单侧视野识别成绩无显著差别,而同音与近义材料则表现出双侧呈现显著优于单侧呈现的作业成绩。最后结合脑功能成像研究,对加工阶段影脑半球佃同活动的原因进行了讨论。     

Failure-Related Action Orientation and Life Satisfaction: The Mediating Role of Forgivingness

This study examined the association between failure-related action orientation and life satisfaction, with a primary focus on confirmation of the mediating role of forgivingness in Chinese college students. 277 participants (165 males and 112 females) from Mainland China completed a subscale of the Action Control Scale (ACS-90) called the Failure-related Action Orientation Scale (AOF), the Tendency to Forgive Scale (Brown in Personal Soc Psychol Bull 29(6):759–771, 2003) and the Satisfaction with Life Scale (Diener et al. in J Personal Assess 49(1):71–75, 1985). Results from structural equation modeling showed that forgivingness partially mediated the relationship between failure-related action orientation and life satisfaction. Moreover, AOF, forgivingness and life satisfaction did not differ across gender or age groups. Implications for the model of failure-related action orientation, forgivingness and life satisfaction in college students are discussed.
