Guiding Low Spatial Ability Individuals through Visual Cueing: The Dual Importance of Where and When to Look

Research suggests that spatial ability may predict success in complex disciplines including anatomy, where mastery requires a firm understanding of the intricate relationships occurring along the course of veins, arteries, and nerves, as they traverse through and around bones, muscles, and organs. Debate exists on the malleability of spatial ability, and some suggest that spatial ability can be enhanced through training. It is hypothesized that spatial ability can be trained in low-performing individuals through visual guidance. To address this, training was completed through a visual guidance protocol. This protocol was based on eye-movement patterns of high-performing individuals, collected via eye-tracking as they completed an Electronic Mental Rotations Test (EMRT). The effects of guidance were evaluated using 33 individuals with low mental rotation ability, in a counterbalanced crossover design. Individuals were placed in one of two treatment groups (late or early guidance) and completed both a guided, and an unguided EMRT. A third group (no guidance/control) completed two unguided EMRTs. All groups demonstrated an increase in EMRT scores on their second test (P < 0.001); however, an interaction was observed between treatment and test iteration (P = 0.024). The effect of guidance on scores was contingent on when the guidance was applied. When guidance was applied early, scores were significantly greater than expected (P = 0.028). These findings suggest that by guiding individuals with low mental rotation ability “where” to look early in training, better search approaches may be adopted, yielding improvements in spatial reasoning scores. It is proposed that visual guidance may be applied in spatial fields, such as STEMM (science, technology, engineering, mathematics and medicine), surgery, and anatomy to improve student's interpretation of visual content.

优秀女子足球运动员间歇性恢复能力的评价研究     

秦旸  张娜 《南京体育学院学报(社会科学版)》2016,(2):103-107

目的：：探讨运用限定级数YO-YO IR2测试以及心率恢复速率评价我国优秀女足运动员的间歇恢复能力。方法：运用测试法对2013年冬训期间的10名国家女足运动员进行YO-YO IR2测试、心率监控以及比赛监测，采集运动员测试跑动距离、心率特征以及比赛中高强度跑动距离，进行统计学分析。结论：女足运动员YO-YO IR2测试结果以及心率恢复速率与比赛中的高强度跑动能力具有紧密相关性，提示YO-YO IR2测试以及心率监控可以作为评价女足运动员间歇性恢复能力的有效方法。与传统的力竭性YO-YO IR2测试法相比，采用限定级数的YO-YO IR2测试后的心率恢复速率评价更易于女足运动员接受，在训练中具有更好的适用性。  相似文献   

认知负荷对乒乓球运动员注意空间的影响*     

杨〓义  岳珍珠 《广州体育学院学报》2019,(2):99-101

目的 同时注意空间中多个目标刺激对于乒乓球运动员非常重要。考察认知负荷对青少年乒乓球运动员注意分布的影响。方法：实验中采用计算机行为实验，控制认知负荷（同时注意的目标数量为2、4或6个），并且在不同注意范围（离中央注视点3°、6°和9°视角）的位置上同时呈现刺激，要求被试对刺激的亮度变化做辨别反应。结果：:认知负荷对于乒乓球运动员的注意范围有显著调节。当刺激个数为2时，在3°和6°视角条件下呈现的刺激反应时均显著快于9°视角条件下的刺激。当刺激个数为4时，视角为3°条件下的反应时快于视角为6°和9°时的反应时，而视角为6°时又比视角为9°时的反应时显著要快。当刺激个数为6时，视角为3°时的反应时均快于视角为6°和9°时的反应时。结论：当前研究证明随着认知负荷增加，乒乓球运动员注意焦点范围显著缩小。可以通过测量运动员在高负荷条件下注意焦点的范围来进行运动员的选拔。  相似文献

踢毽子动作发展序列特征研究及案例教学分析     

王兴泽 《北京体育大学学报》2016,39(11):89-96+118

摘要：为了发扬民族传统体育项目的健身锻炼功效、发挥中小学踢毽子活动的育人功能，以及科学探索不同年龄阶段健康个体在学习踢毽子动作时的典型动作特征。采用现代动作学科知识理论研究民族传统体育项目是传承传统文化的具体体现，也是实施体育育人的操作手段。梳理文献资料得出U6—14阶段健康个体典型的动作发展特征，即U6—7阶段的学习运用自我、U8—9阶段的基本动作过程学习、U10—11阶段的基本运动技能的学习和应用，以及U12—14阶段的基本动作技术向专门动作技术过渡。录像观察得出踢毽子活动的动作发展序列特征，即，整体发展序列的5个阶段和4个部位发展序列的不同阶段发展特征。案例教学实验分析了义务教育阶段体育与健康课程标准、教科书、教师用书中关于踢毽子课程设置的客观性，得出U6—7阶段和U10—11阶段踢毽子课程设置难度大。本文揭示了儿童、青少年踢毽子动作的学习与掌握不仅依赖于直接教学，更要关注儿童、青少年的发展；体现儿童、青少年对特定运动项目的学习特征是自然发展的，而不应是学习与训练促成的。  相似文献

定向行走课程与教学专业能力研究     

杞昭安 《现代特殊教育》2020,(2):26-37

从感觉训练、概念发展、行动技能、定向系统、求助技能、安全议题、小区资源与大众运输系统七个方面选取50项能力指标,对海峡两岸64名担任定向行走课程的教师进行问卷调查。调查结果显示:大多数被调查者认可这50项能力指标;定向行走教师对自己的课程与教学专业能力认可度多为中等,需要进一步作培训。同时发现,在定向行走课程与专业能力各向度的重要程度上,海峡两岸定向行走教师的认知有显著差异,各向度胜任程度的差异更加明显;而定向行走教师的年龄对定向行走课程与教学专业能力在重要程度和胜任程度上并没有显著差异;海峡两岸担任定向行走课程的教师,多数认为有培训的必要。建议将重要性在3.5以上的题目编制为《定向行走专业能力检核表》;将定向行走专业能力胜任程度在3.5以下的向度作为定向行走师资培训的参考。  相似文献

运用文献资料法对近年来我国开放式运动技能研究的相关文献进行整理分析.指出,开放式运动技能研究在我国起步晚、重视程度不高,实践研究水平跟不上理论研究水平;理论研究主要以心理学和生理学为研究角度;实验研究主要集中在篮、网、足等少数项目,研究的深度、专门性和针对性都不够,评价系统不完善.认为,未来研究将深入竞技体育、学校体育、群众体育中,针对不同训练对象、不同训练目的对具体项目的训练原则、方法、手段及评价体系进行研究.  相似文献   

Improved children’s motor learning of the basketball free shooting pattern by associating subjective error estimation and extrinsic feedback     

Leandro de Carvalho da Silva  Carla Ferro Pereira-Monfredini 《Journal of sports sciences》2017,35(18):1825-1830

This study aimed at assessing the interaction between subjective error estimation and frequency of extrinsic feedback in the learning of the basketball free shooting pattern by children. 10- to 12-year olds were assigned to 1 of 4 groups combining subjective error estimation and relative frequency of extrinsic feedback (33% × 100%). Analysis of performance was based on quality of movement pattern. Analysis showed superior learning of the group combining error estimation and 100% feedback frequency, both groups receiving feedback on 33% of trials achieved intermediate results, and the group combining no requirement of error estimation and 100% feedback frequency had the poorest learning. Our results show the benefit of subjective error estimation in association with high frequency of extrinsic feedback in children’s motor learning of a sport motor pattern.  相似文献   

Spontaneous spatial strategy use in learning from scientific text     

《Contemporary educational psychology》2017

Two studies explored the role of the spontaneous use of spatial note-taking strategies (i.e., creating maps and drawings) and spatial ability in learning from a scientific passage. In Study 1, college students read and took notes by hand on a 10-paragraph scientific passage about the human respiratory system. Students tended to use verbal strategies such as lists (on 48% of the paragraphs), outlines (29%) and running text (15%), but also used spatial strategies such as maps (28%) and drawings (11%). Regression analyses indicated that spatial ability and the use of spatial strategies (maps or drawings) significantly predicted learning outcomes, with spatial strategy use explaining additional variance beyond spatial ability. In Study 2, students read the same scientific passage and took notes either by hand on paper (paper group), by hand on a large whiteboard (whiteboard group), or on a laptop computer (computer group). A similar general pattern as Study 1 was found for the paper group, but this pattern was not found for the computer or whiteboard groups, suggesting that the relationships found in Study 1 might depend on the note-taking medium. Results also indicated that students in the paper and whiteboard groups spontaneously used more spatial strategies, whereas the computer group tended to use verbal strategies (i.e., words only), suggesting that different note-taking contexts encourage different strategies.  相似文献
