Two studies were conducted to examine whether infants' reenactment of intended but unconsummated acts in A. N. Meltzoff's (1995) failed-attempt paradigm is due to reading the adult's underlying intention or to the effects of nonimitative social learning processes. Two novel conditions that emphasized the object affordances and the spatial contiguity of the object sets were devised. When infants' first actions only were counted, infants who observed the full-demonstration model produced more target acts. When all target acts produced within the 20-s response period were counted, infants in the emulation-learning and spatial contiguity conditions produced as many target acts as infants in the full-demonstration and failed-attempt conditions. This pattern of findings suggests that nonimitative social learning processes may influence infants' response in the behavioral reenactment paradigm. 相似文献

This study investigated the effects of color combinations for the figure/icon background, icon shape, and line width of the icon border on visual search performance on a liquid crystal display screen. In a circular stimulus array, subjects had to search for a target item which had a diameter of 20 cm and included one target and 19 distractors. Analysis showed that the icon shape significantly affected search performance. The correct response time was significantly shorter for circular icons than for triangular icons, for icon borders with a line width of 3 pixels than for 1 or 2 pixels, and for 2 pixels than for 1 pixel. The color combination also significantly affected the visual search performance: white/yellow, white/blue, black-red, and black/ yellow color combinations for the figure/icon background had shorter correct response times compared to yellow/blue, red/green, yellow/green, and blue/red. However, no effects were found for the line width of the icon border or the icon shape on the error rate. Results have implications for graphics-based design of interfaces, such as for mobile phones, Web sites, and PDAs, as well as complex industrial processes. 相似文献

The relationships between social axioms, general beliefs that people hold about the social world, and values, defined as desirable goals for life, were examined in five cultural groups. Results show that the correlations between social axioms and Schwartz's (1992) values are generally low, suggesting that they represent two distinct types of construct. Based on a structural equation modelling approach, results further show that generally speaking, the five axiom dimensions are related to the value types in a meaningful and interpretable manner, and that these relationships are generally similar across the five cultural groups. Implications of these results and directions for future research are discussed. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

政府与自然的和谐:节约型政府理念中的和谐社会 总被引:5,自引:0,他引:5
以新时期节约型政府理念的核心意蕴分析为视角,广义的和谐社会也就是一种政府与自然和谐的社会。其理论内涵的完整内容应既包括政府以及政府引导社会如何改造与利用自然以实现自身存在与发展的需要,也包括政府以及政府引导社会如何改造和完善自身以满足遵循与顺应自然的需要。构建政府与自然和谐的节约路径主要在于树立强化政府的节约意识和建立健全政府的节约制度。 相似文献

时间洞察力的理论研究 总被引:4,自引:0,他引:4
对时间洞察力的理论研究进行了总结和回顾,把时间洞察力的观点归纳为八个方面:时间洞察力的发展观、性别观、学业观、生活观、文化观、健康观、人格观及精神病理学观点。认为时间洞察力研究应该把重点放在理论构建和因果关系的探讨上。 相似文献

中学生自我概念、学业归因与学业成绩关系的研究 总被引:9,自引:0,他引:9
该研究采用问卷法探讨中学生自我概念、学业归因与学业成绩的关系,并分别对初中生和高中生建立了因果关系模型。两模型区别在于:(1)学业成绩对初中生自我概念的影响大于对高中生的;(2)高中生学业自我概念受内部控制、非学业自我概念受未知方控制直接影响。研究还表明:(1)初中生的学业自我概念显著高于高中生的;(2)学业自我概念、一般自我概念与学业成绩高低一致;(3)内部控制源与有势力的他人控制源显著相关。 相似文献
