Insight into neuromuscular control of movement is gained through an understanding of the mechanical causes of movement. Data on new walkers' net joint moments is scarce, however, although those moments can be considered the direct cause of movement. The authors' goal in this research project was to characterize net joint moments in toddlers (N = 10) during the first 5 months of independent walking and to discuss their role in mechanical control of walking. The authors modeled leg segments as oscillating pendulums fixed at the proximal joint and investigated the relationship between force and movement. Their investigation revealed that at the onset of independent gait, walking was primarily hip driven. Furthermore, the toddlers seemed to experience problems in uncoupling active and passive control around the joints. Changes in mechanical control of walking were observed after 3 to 4 months of independent walking. The changes were more obvious at the hip and the knee joint than at the ankle. 相似文献

Language interface plays a critical role as the foundation of communication. Possessing greater fluency in the host language can lead to increased opportunities for interaction with host members. This research is to examine the impact of language and Internet usage anxiety and self-efficacy on the intended uses of Internet sites, respectively. By the same token, whether Internet/language self-efficacy would mediate the effects of Internet/language anxiety on the intention of the Internet site use is also examined. A valid sample of 368 undergraduates was tested in this study. The path analysis results mostly supported the model tested. The results display that the anxiety of language and Internet use have significantly influenced self-efficacy of Internet use and language, respectively. Anxiety about language and Internet use have also significantly influenced the intention to use Internet sites individually. Furthermore, language self-efficacy has significantly influenced the intention to use Internet sites, but Internet self-efficacy has not. The implications are discussed at the end of the paper. 相似文献

Prior research seems to have neglected the factors that influence consumers to use price information as an indicator of quality or sacrifice. Based on the concept of 'goal looms larger', Study 1 in the present research demonstrated that the extent to which consumers use price information as an indicator of quality or sacrifice is a function of consumer goal (promotion focus vs prevention focus). Study 2 demonstrated that extremeness aversion is a function of consumer goal. The extent of extremeness aversion is significantly greater for prevention-focused consumers than for promotion-focused consumers. 相似文献

任务切换是执行控制的一种重要功能。切换代价是量化执行控制持续时间的指标。并广泛应用于各个研究领域。但是切换代价在多大程度上体现了执行控制的作用,仍然还存在争论.当前主要存在任务设置重构、任务设置惯性和联结竞争三种理论。本文首先介绍了三种理论的基本观点和实验证据,以及对任务切换加工机制的分析;其次阐明了对三种理论进行整合的相关研究;最后分析了进一步研究的方向。 相似文献

类别不确定下的特征推理是基于类别还是基于特征联结 总被引:1,自引:0,他引:1
共有3个实验探讨归类不确定情况下的特征推理是基于类别进行还是基于特征联结进行。实验1在中文条件下重复了Verde等人2005的实验,得出了与之相符的结果,这个结果用基于类别的理性模型的设想或者是用基于特征联结的设想都可以解释。实验2考察被试在靶类别的类别特征频次并且特征结合出现频次高低不同的条件下特征推理的情况,实验2的结果表明,高集中与低集中两种条件下特征推理没有显著差异,不符合特征推理是基于类别进行的设想,而与特征推理是基于特征联结进行的设想吻合。实验3进一步考察被试在特征结合出现的总频次并且靶类别中特征结合出现的总频次高低不同的条件下特征推理的情况,结果表明,在高结合条件下进行特征推理要优于在低结合条件,支持了在归类不确定情况下的特征推理是基于特征联结进行的设想。据此可以认为,人们的特征推理是基于特征之间联结的频次进行,而不是基于类别进行 相似文献

Purpose This research conceptualizes and tests an integrative model of customer loyalty by linking two important theories: expectation–confirmation
theory and self-determination theory.
Design/Methodology/Approach The model is examined using data obtained from 207 part-time students who have encountered the service of a skincare and beauty
salon in Taiwan. These students work as full-time professionals in a variety of industries during the daytime and are financially
independent for their daily consumption.
Findings The empirical results of this study indicate that loyalty is positively influenced by both intrinsic regulation and identified
regulation, while introjected regulation and external regulation are insignificantly related to loyalty. Affected positively
by service expectation and service confirmation, satisfaction has positive influences on all four dimensions of self-determined
motivation—namely, intrinsic regulation, identified regulation, introjected regulation, and external regulation.
Implications The findings of this study show that the proposed model helps to learn about loyalty formation and its mediating mechanism
in service contexts. Intrinsic regulation and identified regulation may be applied as two potential checkpoints for management
to learn the actual status of customer loyalty based on a constant service quality offered by the service provider.
Originality/Value This study is one of the earliest to integrate expectation–confirmation theory and self-determination theory to explore loyalty.
Besides, this study transplants the traditional application of self-determination theory from educational service to commercial
service in general so that efficient strategies can be made for boosting loyalty. 相似文献
