In 3 experiments, younger and older adults judged the perceived motion of three-dimensional (3-D) figures that rotated in depth either unambiguously or ambiguously. Both groups were found to be equivalent in judging the direction of single rotations of the simulated 3-D objects (Experiment 1). In Experiments 2 and 3, a single unambiguous rotation (prime) was followed 0-3200 ms later by an ambiguous rotation (target). Motion priming was indicated by the disambiguation of the second rotation by the first rotation. 3-D motion priming was initially found to be similar in young and old, but it rapidly reduced in the older participants compared to the younger ones. Using a nonluminance depth cue--occlusion--to induce 3-D motion, diminished contrast sensitivity in the elderly was ruled out as a cause of the reduced priming. The results show that 3-D motion priming exhibits robust age-related decline. An age-related decrease in temporal persistence may account for the reduction in 3-D motion priming in older adults. 相似文献

The present study reported the initial validation of an abbreviated version of the Students' Life Satisfaction Scale- Chinese version (SLSS-Chinese) in two samples of Chinese middle school students. Initial analyses based on the original 7-item scale suggested that the two reverse-worded items functioned differently compared to other items. The plausible reasons behind this finding were discussed based on extant literature on mixed worded scales and cross-cultural research on life satisfaction scales. Then we compared the validity of three formats of the SLSS-Chinese: the 7-item (full scale), the 5-item (positively worded items only), and the 2-item (reverseworded items only) scales, respectively. Convergent evidence suggested that the two reverse-worded items hampered the scale's internal consistency, dimensionality, and validity. Also, the 5-item scale demonstrated good psychometric properties, and was clearly superior compared to the 7-item scale. These findings provide a solid foundation for applying the 5-item SLSS-Chinese in measuring Chinese adolescents' life satisfaction. 相似文献

The purpose of this study is to examine the mediating role of collective self-esteem in the relationship between employees’ perceived corporate social responsibility (CSR) and their work engagement. We also explore the moderating role of employees’ concern for face in the linkage between their perceived CSR and collective self-esteem. A two-wave panel data from a final sample of 217 employees in six companies in Wuhan, China, completed the questionnaire survey. Employees’ perceived CSR has a direct and positive effect on their work engagement, which is partially mediated by their collective self-esteem. Furthermore, employees’ concern for face moderates the relationship between their perceived CSR and collective self-esteem. CSR has a stronger effect on collective self-esteem for employees who concern more for face than for those who concern less for face. Understanding the outcomes, the mediating mechanisms, as well as the boundary conditions of perceived CSR on work engagement, help firms to better formulate their CSR strategy. First, we introduce collective self-esteem as an important mediating mechanism in the relationship between CSR and employees’ work engagement. Second, we identify concern for face as an important limiting condition in the linkage between CSR and employees’ collective self-esteem. Finally, previous research investigating employees’ reactions to CSR has predominantly been conducted in the West. We conduct our study in the Chinese or Confucian context to provide some new and complementary insights. 相似文献

车文博先生主编的《中外心理学比较思想史》通过"四方"文化比较,定义了心理学研究范式的意义,进而建立了一个公正的文化视角下的心理学元理论体系。该书更进一步以心理内容为线索,站在"类心理学"的高度描绘了中外心理学范式竞争与演进的历史:古代"四方"文化范式呈现相互竞争的态势;在欧洲的科学革命以后,分析理性哲学范式取得了绝对的统治地位。最后,该书中外心理学思想的交流是解决当前心理学范式困难的出路。 相似文献

Previously we reported that priming of visual motion perception is reduced in older adults compared to younger adults (Jiang, Greenwood, & Parasuraman, 1999, Psychology and Aging, 14(4), 619; Jiang, Luo, & Parasuraman, 2002b, Neuropsychology, 16(2), 140). To examine the neural mechanisms underlying this age-related effect, event-related brain potentials (ERPs) were recorded during perceptual judgments of motion directions by younger and older adults in two experiments. When judging single-step motion, both younger and older adults evoked significantly larger ERP late positive component (LPC) responses to unambiguous motion compared to LPC responses elicited by ambiguous motion. In contrast, compared to the younger adults, the older adults evoked comparable but delayed ERP responses to single motion steps. In the second experiment the younger and older groups judged the directions of two successive motion-steps (either motion priming or motion reversals). Under short (200-400 ms) stimulus onset asynchrony (SOA), the difference between the ERP responses to priming and reversal conditions was significantly larger for the younger than for the older adults. This study provides the first electrophysiological evidence that brain aging leads to delayed processing of single motion direction and visual motion priming as early as 100 ms in the early visual cortex. Age-related changes in strength and temporal characteristics of neural responses in temporal-parietal regions were particularly pronounced in older adults when successive motion signals are placed closely in time, within 400 ms. 相似文献

洪谦先生是维也纳学派在中国的主要传人,但在历史上,第一个向国内学术界介绍维也纳学派的哲学家是张申府及其胞弟张岱年.洪谦对维也纳学派思想在中国的传播起到了关键作用.冯友兰也曾对维也纳学派做过介绍和分析,并试图利用逻辑分析的方法处理形而上学问题.金岳霖及其学生殷海光从逻辑学研究的角度对维也纳学派哲学在中国的传播发挥了作用.洪谦与冯友兰之间在20世纪40年代发生的学术争论,反映了中西两种哲学思维方式的差异.虽然经历了政治上的磨难,但正是由于洪谦先生毕生坚持了对维也纳学派思想的研究和发展,最终成为国际著名的哲学家.洪谦与冯友兰之间的思想交锋也反映了他们对哲学性质的不同理解. 相似文献

"爱情"与"友谊"概念表征的差异——基于字词联想的比较 总被引:1,自引:0,他引:1
运用字词联想法对大学生爱情和友谊概念表征的异同进行了初步探究.以"爱情"和"友谊"为靶词,让被试进行自由联想,之后对搜集到的11136个联想词进行内容分析,在前人研究的基础上最终编码为18个范畴.结果显示,爱情相对需要更多的理性与情感投入、经历更多的痛苦、肩负更多的责侄,容易联想到婚姻、家庭、命运缘分,而友谊较少牵扯.与爱情相比,友谊更易于转化为爱情,而经历过爱情的人很难再回归到友谊.这些结果与日常观念相符,为如何处理爱情和友谊的关系提供了实征指导. 相似文献

选取高生态学效度的科学发明问题作为实验材料, 采用“学习−测试”的两阶段实验范式, 利用静息态功能磁共振成像技术, 基于局部一致性(ReHo)和低频振幅(ALFF)的分析方法, 研究科学发明问题解决的神经机制。在控制被试性别、年龄和常规性问题解决能力后, 结果发现左侧前扣带回(Anterior Cingulate Cortex, ACC)的ReHo值和个体科学发明问题解决的正确率显著正相关, ALFF的结果同样印证了这一发现。结果强调了ACC在科学发明问题解决过程中的重要作用。 相似文献
