ABSTRACT Introduction: The aim of this study was to evaluate whether the classic asymmetry seen in hemispheric functioning is modified in older adults by using a verbal-manual concurrency task. Method: Thirty-five right-handed participants divided into two groups according to age (15 older participants, mean age: 68 ± 8 years, without cognitive decline and 20 younger participants, mean age: 23 ± 2 years) had to perform a 30-second uni-manual tapping task, in both a single task (tapping alone) and dual task (tapping and performing a letter fluency task together) condition. Results: In younger participants, the letter fluency task disrupted the right hand more than the left hand whereas, in older participants, the letter fluency task disrupted both hands equally. Conclusion: These results should be considered preliminary data using a behavioral dual task condition, which might be useful for studying lateralized hemispheric functioning and the processes of divided attention during aging. 相似文献

洛维特认为,在黑格尔、费尔巴哈和马克思之间存在一种概念的历史谱系,那就是他们在各自的思想中都探讨了人,对人做出了定义,所不同的是,人在他们思想中的地位和对人的探讨的科学性是不一致的.人在黑格尔的绝对精神的体系中没有独立的地位和客观性;费尔巴哈将人定义为抽象的"我-你"关系,从而使人失去了他的社会历史基础;马克思则通过对人存在于其中的社会生产方式的分析,实现了对人的真实的阐释.同时,马克思试图克服资本主义条件下所产生的人的自我异化现象,并以共产主义社会中"真正的人道主义"来标识人的解放,来打破在资本主义社会中人的目的和手段、对象和人、使用价值和交换价值、主体和客体间相互关系的颠倒. 相似文献

Abstract. Developing a scientifically grounded philosophy of cosmic evolution, and using the moral norm of completeness as dynamic harmony, this paper argues that humans are a part of nature in both its conserving and emergent aspects. Humans are both material and cultural, instinctual-emotional and rational, creatures and creators, and carriers of stability and change. To ignore any of the multifaceted aspects of humanity in relation to the rest of nature is to commit one of a number of fallacies that are grounded in a dualistic-conquest mentality. Examples of some new developments in philosophy and theology, metaphorical images, and ritual show how to overcome dualism in favor of a dynamic harmony of humanity within nature. 相似文献

Summary In visual perception complex movements are usually split up into components — e.g., in such a way that a moving reference system is applied, to which partial movements can be related. In the following experiment a perceptual vector analysis of this kind was investigated. It was shown that 1) a radial translatory movement (relative component) can be isolated perceptually from a rotatory movement (global component) and that 2) the precision of this decomposition of the complex movement is dependent on the strength at which the rotating reference system is anchored perceptually.The authors wish to thank M. Rauterberg for collecting the experimental data 相似文献

A 2×2×2 factorial design was employed to examine the influence of instructed leadership style, sex of leader, and sex of followers on leader behavior, subordinate satisfaction, and productivity in a simple task. In general, male and female leaders were equally able and equally willing to display autocratic and democratic leadership styles if so instructed. Similarly, leader sex did not have a significant influence on subordinate satisfaction or productivity either by itself or in interaction with leadership style or follower sex. 相似文献

School attendance problems (SAPs) are heterogeneous with respect to etiology and presentation. The long history of conceptualizing SAPs has led to a vast array of terms and definitions as well as different perspectives on the most helpful approach to classification. For educators, practitioners, researchers, and policymakers, this presents a challenge in understanding, assessing, and intervening with SAPs. This paper outlines evolution in the conceptualization of SAPs, focusing on two contemporary approaches to differentiating between them. One approach draws on the longstanding differentiation between SAP types labeled school refusal, truancy, and school withdrawal. A fourth type of SAP, labeled school exclusion, is also considered. The other approach focuses on the function of absenteeism, measured via the School Refusal Assessment Scale (SRAS). Anecdotal and scientific support for the SAP typology is presented, along with the benefits and shortcomings of the SRAS approach to differentiation. The paper offers suggestions for how to differentiate between SAPs and introduces the SNACK, a brief screening measure that permits differentiation by SAP type. 相似文献

Adaptation to field displacement during head movements in the direction with the head rotation and in the direction against it was produced under otherwise identical conditions and compared; the field displacement rate was also varied. A rapid training procedure was used, and a novel one-trial test was employed that could measure the adaptation well enough to compare the effects of various training conditions. The one-trial test measured the magnitude of one of the manifestations of adaptation, the apparent displacement of a stationary target during head movements. This apparent horizontal target displacement was transformed into an oblique one by having the head movements that brought forth the apparent target displacement simultaneously cause an objective vertical target displacement. The slant of the resultant apparent motion path varied with the magnitude of the apparent horizontal target displacement. It was measured by having S reproduce its slant angle. It was found that adaptation to field displacement in the direction with the head rotation was consistently greater than adaptation to the opposite displacement conditions. An explanation for this result is offered. 相似文献
