以大学生为被试,通过情境实验考察存在不安全感对内隐物质主义态度及外显物质主义倾向的影响,并探索潜在的动机机制:控制感寻求的中介作用。结果表明,高存在不安全感组的内隐物质主义态度显著高于低存在不安全感组,控制感寻求在其中起中介作用;但存在不安全感对外显物质主义倾向的影响并不显著。该结果为死亡心理防御的动机机制提供了新的实证依据:对中国被试而言,物质主义也是个体应对存在不安全感的一种策略,该策略可以满足个体寻求确认和控制的需要。  相似文献

以59家科技型创业企业368名知识员工为被试,从新型员工—组织关系模式下个体认知的视角,探讨了企业真实创新预览与知识员工可雇佣型建言的关系,以及知识员工之企业可雇佣性责任感的中介作用。PLSSEM分析结果表明:(1)企业真实创新预览对知识员工的企业可雇佣性责任感各维度、可雇佣型建言具有显著正向影响;(2)知识员工的企业可雇佣性责任感各维度中,基于角色内胜任力提高、基于角色外能力提升2个维度对知识员工可雇佣型建言具有显著正向影响,并在企业真实创新预览与知识员工可雇佣型建言之间起部分中介作用;而基于个人生涯发展维度对知识员工可雇佣型建言的影响不显著,其在企业真实创新预览与知识员工可雇佣型建言之间也不起中介作用。  相似文献

孟喜为西汉象数易的创建人,其易学后人称之为“卦气”。卦气乃结合“学”与“术”成一结构庞大的思想体系。就学而言,乃承受先秦伏、文、孔三圣的易学精神;就术而言,乃用于当时流行的占断灾异、吉凶及祸福。然而后世易学界受儒学重经思想的影响,多轻视象数,以“术家”视孟喜。作者兹特提出孟氏卦气中对于六十四卦卦序之排列。并详作象敷之解析,以见孟氏易学实具有学术思想之价值。  相似文献

The results reported herein support the hypotheses that (1) situation-specific, contextual features of a task can cause people to use explanation-based reasoning (Pennington and Hastie, 1993); (2) such reasoning can cause experienced personnel, both individually and in two-person teams, to reinterpret the meaning of the same information when it is presented in two different ordered sequences; and (3) the result will be primacy or recency (or no) effects depending on whether the most recent conflicting information can be explained away or not, respectively. These results extend the belief-adjustment model proposed by Hogarth and Einhorn (1992), which does not address information reinterpretations, and always predicts recency effects for an evaluation task with a short series of conflicting information. More generally, the results demonstrate the importance of situation-specific, contextual features in understanding judgment processes. © 1997 John Wiley & Sons, Ltd.  相似文献

Negative beliefs about only children suggest that they are spoiled and unlikable, with these early personality differences persisting across the lifespan. Early research found little support for the idea, yet, negative views towards only children remain prevalent. The current research re-visited the issue using a large national panel study of New Zealand adults (N = 20,592) to assess mean differences in personality between those with and without siblings. Adults with no siblings reported significantly lower levels of conscientiousness and honesty-humility and higher levels of neuroticism and openness than adults with siblings; however, mean differences failed to reach the threshold of even a small effect size (|d’s| = 0.08–0.11). Beliefs about only children appear to contradict actual group differences.  相似文献

Muscle fatigue is a complex phenomenon, consisting of central and peripheral mechanisms which contribute to local and systemic changes in motor performance. In particular, it has been demonstrated that afferent processing in the fatigued muscle (e.g., shoulder), as well as in surrounding or distal muscles (e.g., hand) can be altered by fatigue. Currently, it is unclear how proximal muscle fatigue affects proprioceptive acuity of the distal limb. The purpose of the present study was to assess the effects of shoulder muscle fatigue on participants’ ability to judge the location of their hand using only proprioceptive cues. Participants’ (N = 16) limbs were moved outwards by a robot manipulandum and they were instructed to estimate the position of their hand relative to one of four visual reference targets (two near, two far). This estimation task was completed before and after a repetitive pointing task was performed to fatigue the shoulder muscles. To assess central versus peripheral effects of fatigue on the distal limb, the right shoulder was fatigued and proprioceptive acuity of the left and right hands were tested. Results showed that there was a significant decrease in the accuracy of proprioceptive estimates for both hands after the right shoulder was fatigued, with no change in the precision of proprioceptive estimates. A control experiment (N = 8), in which participants completed the proprioceptive estimation task before and after a period of quiet sitting, ruled out the possibility that the bilateral changes in proprioceptive accuracy were due to a practice effect. Together, these results indicate that shoulder muscle fatigue decreases proprioceptive acuity in both hands, suggesting that central fatigue mechanisms are primarily responsible for changes in afferent feedback processing of the distal upper limb.  相似文献

Previous studies suggest that functional ankle instability (FAI) may be associated with deficits in the ability to sense muscle forces. We tested individuals with FAI to determine if they have reduced ability to control ankle muscle forces, which is a function of force sense. Our test was performed isometrically to minimize the involvement of joint position sense and kinesthesia. A FAI group and a control group were recruited to perform an ankle force control task using a platform-based ankle robot. They were asked to move a cursor to hit 24 targets as accurately and as fast as possible in a virtual maze. The cursor movement was based on the direction and magnitude of the forces applied to the robot. Participants underwent three conditions: pre-test (baseline), practice (skill acquisition), and post-test (post skill acquisition). The force control ability was quantified based on the accuracy performance during the task. The accuracy performance was negatively associated with the collision count of the cursor with the maze wall. The FAI group showed reduced ability to control ankle muscle forces compared to the control group in the pre-test condition, but the difference became non-significant in the post-test condition after practice. The change in performance before and after practice may be due to different degrees of reliance on force sense.  相似文献

In this article, I describe how I encountered cybernetics and how it became an important part of my life. I begin with an account of my time at Brunel University and also describe how I came to work with Gordon Pask, one of the few intellectuals and researchers in the UK who styled themselves as cyberneticians. To enrich my story, I include an overview of the story of cybernetics as I perceive it. Given the importance I attach to cybernetics as an intellectual tool, I end with a plea for it to be included in all educational curricula.  相似文献

Objective: The aim of this study was to examine whether illness representations of control and consequences mediate the relation of cardiac patients’ affect to well-being. A further aim was to examine this indirect relationship at a dyadic level (i.e. patient and spouse). Design and main outcome measures: One hundred and four patients with a cardiovascular disease and their spouses participated in the study. Positive and negative affect was assessed at baseline; illness representations were assessed 2 months later, and physical and psychological well-being 4 months later. Results: Illness representations generally mediated the impact of patients’ and spouses’ affect on well-being, while several actor and partner effects were found. However, it was only positive affect that was indirectly related to well-being, while the representations of personal and treatment control chiefly acted as mediators. The effects were stronger for patients than spouses, as well as for physical well-being. Conclusion: The results underline the strong connection between illness-related self-regulation and the overall person/environment interaction as depicted by affect. They also indicate the need to integrate theories on adaptation to illness, with models describing adaptation of couples to stressful conditions, and specific theories about the role of emotion in adaptation to illness.  相似文献
