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

Victoria A. Roach  Graham M. Fraser  James H. Kryklywy  Derek G.V. Mitchell  Timothy D. Wilson 《Anatomical sciences education》2019,12(1):32-42

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.

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   

Libraries and Spatial Literacy: Toward Next-Generation Education     

Benjamin D. Branch 《College & Undergraduate Libraries》2014,21(1):109-114

The role of the library is to assist citizens in skills development critical to national interest and empowerment as literacy ambassadors, in general. Specifically, the work by the Federal Geographic Data Committee (1994) indicates that spatial literacy is for every citizen and not just a set of workforce specialists. Hence, the use of maps in decision making and problem solving will become fundamental to all professions, including library professionals. Thus, a spatial literacy awareness and rationale for such as standard job ability is discussed as a future librarian workforce proficiency and knowledge transfer medium.  相似文献

老铁山—长兴岛VLCC外海航路安全水深的确定     

李连博  刘德新  尹建川  戴冉 《上海海事大学学报》2016,37(2):1-6

为确保长兴岛北港区30万吨级油船泊位正常营运，科学合理地规划老铁山水道至长兴岛北港区的外海航路，对国内外关于航道水深的标准、规范和影响船舶富余水深的要素进行对比分析.基于MATLAB 8.0平台，利用芳村公式、Eryuzlu（1994）修正公式和Norbin公式计算船舶在开敞水域航行时的下沉量、富余水深和安全水深，并画出满载VLCC在开敞水域航行时的下沉量、富余水深、安全水深在不同航速情况下随水深与吃水比值变化的曲线.根据《海港总体设计规范》、芳村公式、Eryuzlu(1994)修正公式和Norbin公式，计算出在开敞水域航行的满载VLCC在不同航速下所需的下沉量和外海航路安全水深.运用该方法提出老铁山水道至长兴岛北港区外海航路的安全水深建议值.该方法可为渤海湾其他有VLCC码头的外海航路设计提供一定的参考.  相似文献   

Identifying needs and enhancing learning about climate change adaptation for water professionals at the post-graduate level     

David Alan George  Poh-Ling Tan  Jeffrey Frank Clewett 《Environmental Education Research》2016,22(1):62-88

Using a participatory learning approach, we report on the delivery and evaluation of a climate change and risk assessment tool to help manage water risks within the agricultural sector. Post-graduate water-professional students from a range of countries, from both developed and emerging economies were involved in using this tool. Our approach included participative learning tools – group discussion, software, and risk matrices. The materials developed met the needs of the students, allowing these students to incorporate their learning and adapt the package of materials for use in their home countries. Analysis of evaluations show that the tools and materials are particularly useful and emphasizes the need for sound learning materials and tools, funding to deliver training, and policy support to accelerate education and adoption of authentic climate change adaptation practices. The expected benefits for water professionals about climate change will be translated into improved socioeconomic and environmental outcomes if adopted.  相似文献   

基于微博数据的中原城市群空间联系强度测度   总被引：1，自引：0，他引：1  

王开泳  邓羽 《中国科学院大学学报》2016,33(6):775-782

空间联系强度是城市群发展阶段、态势、功能定位的重要表征.在大数据背景下，随着移动终端的普及和网络联系平台的广泛使用，人流在不同地区的空间移动能够得到较准确的统计和表达.在总结以往城市群空间联系研究方法的基础上，提出一种新的基于微博数据判别城市之间空间联系强度的方法，弥补了由于缺乏城际通勤数据而导致的传统空间联系强度判别方法的不足.新方法可以较准确地判别城市群地区各个城市的空间联系强度与组织类型.  相似文献
