Mechanisms of attentional cueing during observational learning to facilitate motor skill acquisition
We examined the effectiveness of different cueing conditions during observational learning of a soccer accuracy pass. Sixty participants (30 males, 30 females) were randomly assigned and stratified by sex into one of six groups: discovery learning, verbal instruction, video model with visual cues, video model with verbal cues, video model with visual and verbal cues, and video model only. Each participant completed eight blocks of 10 trials each, with trial blocks 1 and 2 representing the practice phase (no manipulation), trial blocks 3, 4, 5 and 6 the acquisition phase (manipulation administered) and trial blocks 7 and 8 the retention phase (24 h after acquisition, with no manipulation). Absolute error, variable error and kicking form were recorded. The results indicated that those who used video modelling with visual and verbal cues collectively displayed less error and more appropriate form across acquisition and retention trial blocks compared with other groups. Our findings suggest that verbal information in addition to visual cues enhances perceptual representation and retention of modelled activities to improve task reproduction capabilities. Future research directions are proposed with implications for both direct and indirect perception accounts of skill acquisition through observed behaviours. 相似文献

论康德的道德自由与德性论 总被引：1，自引：0，他引：1
萨·巴特尔 《内蒙古师范大学学报(哲学社会科学版)》2008,37(1):37-41
理性与自由是康德伦理学的重要概念,如若把康德的“理性”概念分为理论理性和实践理性,那么他的“自由”概念同样也可分为理性的自由和道德的自由。理论理性和理性的自由是属于思辨哲学研究的范畴,实践理性和道德的自由是属于伦理学研究的范畴。在康德看来,道德自由是人的道德活动之原因,德性是人的道德活动之结果。因此,在康德伦理学中道德自由与德性之间有着内在的逻辑联系,不仅如此,这种道德自由与德性之内在的逻辑联系恰恰体现着康德理性主义伦理思想的精神内涵。 相似文献

首次全面论述了全世界黄华属(豆科)植物地理。黄华属是豆科少数几个东亚-北美间断分布属之一。对黄华属5组21种的分布进行了分析,发现本属4个频度分布中心依次是：东亚地区(8种／3组,其中特有种4种),伊朗-土兰地区(7种／3组,其中特有种3种),落基山地区(7种／2组,均为特有种)及大西洋北美地区(3种／1组,均为特有种)。基于以下事实：在东亚地区存在本属最多的组与种;在此区可以见到黄华属系统发育系列;该属最原始的组种及最进化的组种也在该区出现等,可以认为东亚地区是该属的现代分布中心及分化中心。伊朗-土兰地区(中亚东部至喜马拉雅)及落基山地区所含种、组数仅次于东亚地区,而且多倍体现象多发生于这两区,因此可认为是本属的次生分布中心及分化中心。在此二地区,物种分化较活跃且复杂,先后描述了很多新种和变种,也曾进行过较多的归并处理。最近的分子生物学证据不断揭示,在这地区曾被归并的一些分类群存在着较大不同,从而提醒分类学家对年轻区系中物种分化较活跃的类群进行分类处理时,无论是建新分类群还是对某些类群进行归并,应持谨慎态度。作者根据黄华属植物的现代地理分布、形态演化趋势、现有的化石及地质历史资料,推测黄华属植物在中新世之前早已形成,并且在晚第三纪欧亚大陆与北美大陆失去陆地连接之前在两大陆已经存在,很可能是于早第三纪或晚白垩纪在劳亚古陆上起源于一个含羽扇豆生物碱的古槐成员。两大陆分离后,在不同的成种因子的影响下,形成了各自的演化格局：在亚洲,晚第三纪的喜马拉雅造山运动、古地中海消失及第四纪冰川作用引起的旱化、寒化,促进了该属植物的强烈分化;而在北美,第四纪的冰川作用及局部的山体隆起,可能是促进该属植物演化的主要动力。根据黄华属植物的系统演化趋势及原始类群的分布式样分析,东亚地区的中国-日本亚区可能是本属植物的原始类型中心。 相似文献

Processes for moderating assessments are much debated in higher education. The myriad approaches to the task vary in their demands on staff time and expertise, and also in how valid, reliable and fair to students they appear. Medical education, with its diverse range of assessments and assessors across clinical and academic domains presents additional challenges to moderation. The current review focuses on medical education, considering double-marking and benchmarking as two broad classes of moderation procedure, and argues that it is the process more than the type of procedure which is crucial for successful moderation. The advantages and disadvantages of each class of procedure are discussed in the light of our medical school’s current practices, and with respect to the limited empirical evidence within medical education assessment. Consideration of implementation is central to ensuring valid and reliable moderation. The reliability of assessor judgements depends more on the consistency of assessment formats and the application of clear and agreed assessment criteria than on the moderation process itself. This article considers these factors in relation to their impact on the reliability of moderation, and aims to help assessors and students appreciate the diversity of these factors by facilitating their consideration in the assessment process. 相似文献

航空航天产品属于高技术产品,同时由于其中大多数都属于军民两用的产品,使得航空航天大国通常对两用物项及技术出口实施管制。法国作为欧盟重要成员国,其除本国出口管制法律制度外,还受欧盟法律规定制约。对法国及欧盟航空航天产品出口管制法律制度进行研究对于我国今后完善相关法律制度具有重要的借鉴意义。 相似文献

The accuracy and variability of a sustained low-level force contraction (2% of maximum voluntary contraction) was measured while participants viewed unpleasant, pleasant, and neutral images during a feedback occluded force control task. Exposure to pleasant and unpleasant images led to a relative increase in force production but did not alter the variability of force production compared to conditions in which participants viewed neutral images. Findings are discussed with respect to prior work, emphasizing arousal specific changes that emerge at low target force levels. 相似文献
