中庸工作重塑研究

采用中庸思想作为研究的理论基础,建构中庸工作重塑概念,并应用于工作要求-资源模型检验其构思效度。在288名医务人员中探索中庸工作重塑的结构,在178名医务人员中验证结构,并探讨中庸工作重塑在工作要求或工作资源与工作投入及工作倦怠之间的中介效应。研究结果发现,中庸工作重塑是由个体取向和群体取向构成的两维结构的工作重塑。其中,在工作要求-资源模型的压力机制中,人们通过工作重塑来降低工作要求引致的工作倦怠,促进工作投入;而在其激励机制中,人们通过工作重塑会增强工作资源的激励作用,促进工作投入。     

汉语阅读困难儿童认知特征研究

为了解汉语阅读困难者的认知特征,本研究从９６７名５年级１１－１３岁学生中抽取了１１８名被试,将他们分成困难组（包括截点组和低成就组）和对照组,并将其在词语理解等８个认知变量上进行了比较。结果表明,图形记忆与加工能力及对词语和一般信息理解能力的缺损是汉语阅读困难者主要的认知特征。研究还表明,一般信息理解能力发展水平是区分一般阅读落后和特殊阅读落后的一个指标。     

缘起与践履--浅谈佛教有关道德实践心理机制的思想

本文以佛教的缘起思想为理论背景,从道德实践的心理动力源、道德实践的目的因、道德实践判断及道德实践的客观依据等四个方面,系统地探讨了佛教有关道德实践心理机制的思想.希望能以此来促进我们对传统道德伦理思想的思考,并有所借鉴.     

执行控制：一个具有广阔理论前途

面对千变万化的世界,我们需要实施计划行为、形成推理、解决问题、同时完成多项任务、适应新的环境和遵守社会规范。而要做到这些,我们必须随时监控外部世界和内心活动,排除或抑制无关信息的干扰,选择必要的信息输入,并从长时记忆中提取有关信息,对这些     

从知觉负载理论来理解选择性注意

知觉负载理论被认为解决了选择性注意研究的早选择和晚选择观点之争。当前任务对注意资源的耗用程度决定了与任务无关的干扰刺激得到多少加工,从而导致在低知觉负载下,注意资源自动溢出去加工干扰刺激（晚选择）,而在高知觉负载下,注意资源被当前任务耗尽而无法加工干扰刺激（早选择）。知觉负载理论提出后,研究者进行了一系列研究。一部分工作专注于知觉负载对选择性注意的调节作用;另外一些工作则关注其他认知过程如何影响注意资源的分配,其中知觉负载与工作记忆负载的关系是当前关注重点。     

卷入对名人广告信息加工效果的影响

使用过程分离程序,考察卷入的两方面(个人卷入与产品卷入)共同对名人广告信息加工效果的影响。发现:(1)个人卷入和产品卷入的提高都能促进受众的品牌记忆,但个人卷入的变化主要影响品牌外显记忆成绩,而产品卷入的提高则表现为内隐记忆效果的增强。说明,两者影响的是同一内部过程,但影响方式可能有异。(2)名人广告中的品牌所获得的外显记忆、内隐记忆效果均明显好于使用一般代言人的品牌;代言人类型与个人卷入或产品卷入间不存在明显的交互作用。说明,名人代言人的使用可促进广告信息的加工,且受卷入状态的影响较小。     

Dissociating viewpoint costs in mental rotation and object recognition

In a mental rotation task, participants must determine whether two stimuli match when one undergoes a rotation in 3-D space relative to the other. The key evidence for mental rotation is the finding of a linear increase in response times as objects are rotated farther apart. This signature increase in response times is also found in recognition of rotated objects, which has led many theorists to postulate mental rotation as a key transformational procedure in object recognition. We compared mental rotation and object recognition in tasks that used the same stimuli and presentation conditions and found that, whereas mental rotation costs increased relatively linearly with rotation, object recognition costs increased only over small rotations. Taken in conjunction with a recent brain imaging study, this dissociation in behavioral performance suggests that object recognition is based on matching of image features rather than on 3-D mental transformations.     

Effects of Electromyostimulation on Knee Extensors and Flexors Strength and Steadiness in Older Adults

It is known that electromyostimulation (EMS) alone or superimposed over voluntary contraction (EV) can effectively improve muscle strength. However, the effect of this type of training on the ability to control force production at submaximal levels is unknown. The authors examined the effects of EV training on steadiness in force production of knee extensors and flexors in older adults. Forty participants, including 20 men and 20 women, 60–77 years of age, were randomly allocated into a control group (CG) and an electromyostimulation superimposed over voluntary contraction (EVG) group. The EVG performed 30 bilateral isometric knee extension and flexion contractions per session, 3 training sessions per week, for 6 weeks. The variations in force production, expressed in absolute (standard deviation [SD]) and relative (coefficient of variation [CV]) terms, were assessed in isometric contractions at 5%, 15% and 25% maximal voluntary contraction (MVC) levels. Results indicated that MVC increased in knee extension and flexion in EVG (p < .05) after the training; steadiness CV also improved at 15% MVC in knee flexion (p < .05) but no significant changes were found in knee extension and steadiness SD. The training-induced changes in MVC were not correlated to steadiness CV that might indicate different mechanisms underlying these adaptations.     

Core Knowledge Employee Creativity and Firm Performance: The Moderating Role of Riskiness Orientation,Firm Size,and Realized Absorptive Capacity

In this study, we examine when creativity is positively or negatively related to firm performance. Building on the creation–implementation tension theorized in the literature and the attention capacity perspective, we argue that the relationship between creativity and firm performance is contingent on riskiness orientation, firm size, and realized absorptive capacity. Data were collected from 761 core knowledge employees, 148 CEOs, and 148 HR executives from 148 high‐technology firms. The results indicated that core knowledge employee creativity was negatively related to firm performance when riskiness orientation was high. The relationship was positive when realized absorptive capacity was high. Finally, the relationship was more positive in small firms than in large firms. We discuss the implications of our findings for creativity research and managerial practices.
