The ability of 1-year-old infants to remember the location of a nonvisible target was investigated in 3 experiments. Infants searched for a toy hidden in one of many possible locations within a circular bounded space. The presence, number, and spatial arrangement of local cues or "landmarks" within this space were varied. The results of Experiment 1 showed that search performance was highly successful when a landmark was coincident with the location of the toy ("direct"), but less successful when a landmark was adjacent to the target location ("indirect"). The results of Experiment 2 suggested that search with an indirect landmark may be more fragile than search with no landmarks at all. In Experiments 3a and 3b, 2 different configurations of indirect landmarks were employed; search performance was equally poor with both of these and was inferior to search with no landmarks. It is concluded that infants of this age are able to associate a nonvisible target with a direct landmark and are able to code the distance and direction of a target with respect to themselves or with respect to the larger framework. However, there was no evidence that they can code the distance and direction of a target relative to another object. The difficulty of coding with indirect landmarks is interpreted in terms of cognitive complexity and conflict between spatial strategies. 相似文献

本认为,发达资本主义国家的繁荣和国际社会主义运动的挫折表面上与“两个必然”渐行渐远,实际上加快了“两个必然”的进程。科技革命、资本扩张和自我调节一方面促进了资本主义的发展。同时也为社会主义准备了更加成熟的条件,社会主义在探索中走上了更加健康的发展道路。但社会主义代替资本主义是一个长期曲折的历史过程。 相似文献

对于以儒学为代表的中国文化传统而言,五四新文化运动具有一定程度的内发性,在一定的意义上可以看作是中国文化传统所内蕴的生命力的现代表征;在基本的精神方向上,20世纪儒家思想的新开展与五四新文化运动保持了内在的一致性;在中国文化近现代化的发展链条中,现代新儒学对于中国文化的现代重建正可以说是接续了五四新文化运动的历史任务,与五四新文化运动一起共同构成了中国文化近现代化的发展链条之中具有紧密联系的有机环节.因此,所谓五四新文化运动是"全盘反传统"的和"五四新文化运动造成了传统的断裂"的论断都是有待商榷的. 相似文献

This article includes a multimethod, multisource analysis and synthesis of the degree to which contemporary family-oriented early intervention policies and practices are family centered. Federal laws and legislation, state-level policy positions, and the viewpoints of service providers and consumers were analyzed as part of the study. The findings, taken together, indicate a movement toward adoption of family-centered early intervention policies and practices at the different levels of analysis. There are, however, discrepancies between what state-level policymakers and "street-level" providers and consumers see as current beliefs and practices within states. 相似文献

Locomotion alters the spatial structure of an observer's perspective, that is, the network of observer to environment distances and directions. The purpose of the present 6 experiments was to investigate the sensitivity of 12-48-month-olds to changes in perspective that are occluded from view by walls and by darkness. To assess sensitivity, children were shown a target object in one room, walked into an adjacent room and asked to point in the straight-line direction at the target. In Experiment 1, 42 12-48-month-olds were tested and results indicated that children older than 36 months responded by pointing straight at the occluded target, whereas younger children tended to point in the direction of their route away from the target. In Experiments 2-4, 24- and 48-month-olds were tested and results demonstrated that 48-month-olds were sensitive to the proprioceptive and to the visual-environmental cues for the changes in perspective structure. The 24-month-olds, however, responded by pointing straight toward the target when visual-environmental cues were absent, whereas they pointed in the direction of their route when they were present. In Experiments 5 and 6 additional 24-month-olds were tested to assess the effects of short-term training and of a continuous view of the target on responding in the presence of visual-environmental cues. The results indicated relatively early sensitivity to proprioceptive cues for changes in perspective and somewhat later sensitivity to appropriate visual-environmental cues under these conditions. 相似文献

We studied a group of fourth grade students identified by their classroom teachers as having above average ability in mathematics who were participating in pull-out enrichment sessions. We sought to test, using observational and microgenetic methods, hypotheses regarding students' measurement strategies that have been generated post hoc by other research teams. These above-average mathematics students did not show initial difficulties with turn commands previously reported in mixed populations. They created strategies to accurately determine the correct direction of turn and to estimate the amount of turn. They did follow a similar developmental order as students in previous work: They synthesized and integrated two schemes, turn as body movement and turn as number. Analyses extending this work revealed a process of psychological curtailment in which students gradually replace full rotations of their bodies with smaller rotations of an arm, hand, or finger.This revised version was published online in September 2005 with corrections to the Cover Date. 相似文献

在时间维度和价值维度上审思高等教育的发展谱系,高等教育的未来与未来的高等教育包含两层含义。其一,指向未来发展路径的高等教育,技术理性与主体性的双向作用不可偏废:技术理性延展了高等教育未来的想象力,主体性纵深了高等教育未来的建构力;同时,技术理性是促成主体性的基础,而主体性引领技术理性的方向,两者共同作用达成高等教育的未来实现。其二,指向未来美好图景的高等教育,需要将主体性置于价值优先地位,以体验式的合作学习进行感入式的沟通对话,发挥主体创造性,超越技术理性,在未来的高等教育的未来中走向真理式的诗意生活。 相似文献

This paper presents findings from a quasi-experimental study evaluating future teachers’ attitudes and beliefs in response to a cross-curricular university course on evolution and creation bridging biological and Christian theological perspectives. Based on previous findings, we hypothesized that a course providing learning opportunities for epistemic insight within this multidisciplinary arena might have effects on attitudes and beliefs relevant to the field. Hence, the main research question was the following: To what extent do student teachers’ attitudes and beliefs change by attending a cross-curricular course on evolution and creation intended to develop student teachers’ epistemic insight into the nature of science and into the relationship between science and theology? The answer from this quasi-experimental evaluation study (pre–post-design; test group n =?26, control group n =?24) is as follows: It depends upon the variable investigated! Pre–post-analysis using a repeated measures ANOVA revealed that the cross-curricular course integrating epistemic insight induced changes in creationist beliefs, in students’ perception of conflict, and in acceptance of evolution. In contrast, there was no effect on attitudes toward evolutionary theory, on attitudes toward the Biblical accounts of creation, or on scientistic beliefs. However, when student responses were analyzed individually, case-based evidence for belief change in students with scientistic positions emerged. Among the reasons for those different effects, we discuss conceptual differences between attitude and acceptance, features of the student teacher sample, and the particular content of the course explicitly addressing creationism but not scientism. In conclusion, the paper corroborates the role of epistemic insight in the multidisciplinary field of evolution and creation and provides initial evidence that epistemic insight possesses a particular potential concerning positions at both ends of the spectrum. 相似文献

Recent eye movement experiments offer preliminary evidence that skilled readers activate word‐level prosodic information when silently reading sentences. This paper reviews the role of eye movements during reading as well as the preliminary evidence for prosodic processing. A new experiment examines whether prosodic processing differs for high and low frequency words. Readers' eye movements were monitored while reading target words presented in sentences preceded by parafoveal previews that either contained the exact initial syllable of the target (i.e. the congruent preview condition) or the initial syllable plus the next letter (i.e. the incongruent preview condition). Reading times on high frequency words did not differ in the congruent and incongruent preview conditions, but reading times on low frequency words were faster in the congruent condition. The implications of the present result and previous studies are discussed in terms of phonological hub theory, which is a production‐based theory of word recognition during skilled silent reading. 相似文献

Impact of inert metal particles flow on aluminium plate 总被引：1，自引：0，他引：1
Inert metal explosive,a new kind of explosive,is a mixture of high explosive and inert metal particle.When this kind of explosive is detonated,an inert metal particle flow will be formed by the ex-plosive product driving.To determine the characteristics of the movement of the metal particle flow,a series of aluminium plates were designed to be the targets on which the metal particle flow impacted.The test result was presented and a numerical model was set up to analyze the impact of the high speed inert metal particles on aluminium plate.Based on the numerical analysis,the relationship between the characteristic of the mark on the target plate and the initial condition of the inert metal particles was pro-posed.From the analysis of the impact on target plates,more information about the movement of the metal particles could be reconstructed. 相似文献
