本文基于关联习得理论, 探讨了模糊产品展示对产品态度的影响。结合4个实验的结果, 发现模糊产品展示对产品态度的影响呈现倒U型。相比于低模糊度的产品展示, 中等模糊度的产品展示能够激发更高水平的柔软度感知, 进而提升产品质量评价, 最终导致产品态度更积极。但过高模糊度的产品展示会激发消费者强烈的消极情绪, 消极情绪对产品态度的消极影响会抵消掉柔软度感知的积极影响, 最终导致产品态度的降低。 相似文献

The Clock Drawing Test (CDT) is a widely used instrument in the neuropsychological assessment of Alzheimer's disease (AD). As CDT performance necessitates several cognitive functions (e.g., visuospatial and constructional abilities, executive functioning), an interaction of multiple brain regions is likely. Fifty-one subjects with mild cognitive impairment, 23 with AD and 15 healthy controls underwent high-resolution magnetic resonance imaging. Optimized voxel-based morphometry (VBM) was performed to investigate the putative association between CDT performance and gray matter (GM) density throughout the entire brain. In the first step of analysis (p<.001, uncorrected), VBM revealed a reduced GM density in numerous cortical (temporal lobe, frontal lobe, parietal lobe, cerebellum) and subcortical (thalamus, basal ganglia) brain regions to be associated with poorer CDT performance. When corrected for multiple comparisons (p<.01), the associations remained significant predominantly in the left temporal and--less pronounced--the right temporal lobe. VBM demonstrated CDT performance to depend on the integrity of widely distributed cortical and subcortical areas in both brain hemispheres with accentuation in the left-sided temporal lobe region. 相似文献

Telework, namely so remote work, is composed of three basic forms: home based-telework, alternated telework and mobile telework. These three basic forms of telework and the traditional form of work are compared to identify their respective impact on work centrality, work social representation, and on relations between work life and out of work life. The mobile teleworkers present a high work centrality and the alternated teleworkers, a high family centrality. Concerning the representation, only mobile teleworkers and home based teleworkers cannot think the work without the basic knowledge of constraint. For the exchanges between work of life and out of work life, traditional workers separate their domains of life even though alternated teleworkers and home based-teleworkers combinate it. Mobile teleworkers develop exchanges between some domains of life.This study proves that it is not necessary to reason globally but to consider the specificity of each telework forms introduced or to implant in a organization. 相似文献

通过对2型糖尿病心血管终点事件的观察,更多的临床证据提示,糖尿病的治疗目标应该以减少心血管事件为主。糖尿病防治从策略上发生了两个转变,即以血糖为中心转向以防治心血管事件为中心的多危险因素综合防治策略;以糖化血红蛋白检测作为血糖评价的金标准转向以血糖量、质、时程控制的全面评价策略。 相似文献

Clinical signs of damage to the egocentric reference system range from the inability to detect stimuli in the real environment to a defect in recovering items from an internal representation. Despite clinical dissociations, current interpretations consider all symptoms as due to a single perturbation, differentially expressed according to the medium explored (perceptual or representational). We propose an alternative account based on the functional distinction between two separate egocentric mechanisms: one allowing construction of the immediate point of view, the other extracting a required perspective within a mental representation. Support to this claim comes from recent results in the domain of navigation, showing that separate cognitive mechanisms maintain the egocentric reference when actively exploring the visual space as opposed to moving according to an internal map. These mechanisms likely follow separate developmental pathways, seemingly depend on distinct neural pathways and are used independently by healthy adults, reflecting task demands and individual cognitive style. Implications for spatial cognition and social skills are discussed. 相似文献

精细阐述与先行信息激活水平的动态变化 总被引:1,自引:0,他引:1
该研究运用窗口阅读及命名探测技术,对即时与延迟状态下合适与不合适背景信息的激活模式进行了探讨。被试阅读含有精细阐述错误信息的语篇,并对合适或不合适的探测词进行命名反应。结果发现,虽然即时条件下,受精细阐述的不合适探测词激活水平高于合适探测词,但当延迟时间为1500ms时,原有的激活模式发生了逆转。这种激活模式的变化主要是由于合适的背景信息随时程延长激活水平得到提升所致。 相似文献

Abstract. Technological changes affect Western culture in three ways: the ratio between the lifetimes of technologies and the human lifetime is inverted; the three principal realms of human life (the home, the workplace, and leisure activity), as well as political systems, are affected; and the cohesion of the social body is threatened. The impact on Eastern culture is softened by a clearer role assigned to school, the resulting level of education, and the influence of Confucian ethics. However, acculturation will vary among countries, depending on the communication ability in the respective societies and the degree of development of social cellular structures, which are the most able to manage complexity. 相似文献
