仪表显示器的照度、对比度、色饱和度对检察速度的影响

本文通过心理物理实验,从工程心理学角度,提出了仪表显示器的照度水平、对比度、色饱和度是相互关联的。它们是保证监盘工检察速度的重要目视条件。文章最后提供了仪表显示器的最佳照度、对比度、色饱和度等参数,可作为仪表显示器和电厂控制室室内设计的参考标准。     

单眼和双眼特定的McCollough效应及倾斜后效的消退过程

每个被试对互补的联合方位的图形适应后均产生单眼特定和双眼特定的McCollough效应。双眼的起始强度大于单眼的起始强度。单眼和双眼的McCollough效应的消退速度基本相同。在自然视觉条件下McCollough效应消退快,在完全黑暗的条件下没有明显的消退。说明导致McCollough效应恢复平衡的主要因素不是自发的过程,而与网膜刺激有关。倾斜知觉后效的消退在上述两种实验条件下没有明显的差别,因此可推测倾斜知觉后效的消退主要是神经疲劳的一个自发的恢复过程。     

中国人眼光谱相对视亮度函数的研究

问 题 人眼对光谱各波长的灵敏度,是产生一种阈限反应或主观相等亮度所需要的辐射能量的倒数。它们原称光谱视亮度,现在我们称之为光谱相对视亮度。即使是等能光谱,各波长引起的相对视亮度也很不相同。具体测量时除绝对阈限法外,一般常用匹配法:使人眼将不同波长的光谱色光分别和一个固定强度的白色标准光作亮度匹配,达     

Culture, control, and perception of relationships in the environment

East Asian cognition has been held to be relatively holistic; that is, attention is paid to the field as a whole. Western cognition, in contrast, has been held to be object focused and control oriented. In this study East Asians (mostly Chinese) and Americans were compared on detection of covariation and field dependence. The results showed the following: (a) Chinese participants reported stronger association between events, were more responsive to differences in covariation, and were more confident about their covariation judgments; (b) these cultural differences disappeared when participants believed they had some control over the covariation judgment task; (c) American participants made fewer mistakes on the Rod-and-Frame Test, indicating that they were less field dependent; (d) American performance and confidence, but not that of Asians, increased when participants were given manual control of the test. Possible origins of the perceptual differences are discussed.     

Leader–follower risk orientation incongruence,intellectual stimulation,and creativity: A configurational approach

Prior work suggests that follower and leader risk orientation is positively associated with follower creativity. We suggest that this view is oversimplified and propose that follower creativity can be stimulated when leader and follower have diverging risk orientations. We, therefore, apply a configurational approach to creativity, evaluating varying combinations of leader and follower risk orientation on follower creativity. Across two field studies, we demonstrate that (a) follower creativity increases as leaders’ and followers’ risk orientations become more discrepant (i.e., incongruent); (b) follower creativity is higher when leader–follower dyads are congruent at moderate levels of risk orientation compared to congruence at the extremes (i.e., low and high levels); (c) follower‐experienced intellectual stimulation mediates the relationship between leader–follower risk orientation incongruence and congruence and follower creativity; and (d) that leader authority openness moderates the indirect effect of leader–follower risk orientation incongruence on creativity via follower‐experienced intellectual stimulation. Theoretical and practical implications specific to creativity and leader–follower relationships are discussed.     

孔子的和谐意识及其现代价值

在中国传统文化中,和谐是一种不散的精神,孔子又是“和”理念的集大成者。他在如何处理人与人、人与社会、人与自然及个人身心关系方面都有一些独到的见解。对孔子思想中的和谐意识进行认真地梳理、审视,自觉汲取其精华,对于我们构建社会主义和谐社会,无疑具有重要的启迪和借鉴意义。     

“言”说

世上大学问多的是,但作为人的第一件大事就是要学会说话;善于用语言来表达自己的思想和观点。会不会与人沟通交流,除与环境和对象有关以外,关键一点在于自己是否有言谈,会辩的技巧;这种技巧主要体现在表达的能力上。常言道:会说话的人不抢着讲,不会讲话的人争着说。其实这一来说明自己态度不谦虚、没礼貌;二来说明个人的表现欲很强;三者说明没有表达涵养。太上爷曰:“知者不言,言者不知。”有智谋的人遇事沉稳,并不急于表现自己;同时说明夸夸其谈只不过是“纸上谈兵”、故弄玄虚、卖弄自己而已;空话一大堆,只会招来别人的厌恶、心烦。进一步…     

3～4岁儿童攻击行为发展的追踪研究

对163名幼儿园小班儿童进行追踪观察,考察3-4岁期间儿童攻击行为的特点、发展模式及稳定性。主要获得以下结果：儿童最普遍的攻击形式是身体攻击．言语攻击和间接攻击的发生率较低;大多数攻击行为属于主动性攻击和工具性攻击;男孩的攻击行为总体上多于女孩．但女孩的间接攻击多于男孩;儿童的攻击性在3-4岁之间无显著变化,但敌意性攻击存在随年龄增长而增加的趋势;3-4岁儿童攻击性的个别差异已具有明显的稳定性。
