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.

A comparison of visual search strategies of elite and non-elite tennis players through cluster analysis     

Nicholas P. Murray 《Journal of sports sciences》2017,35(3):241-246

Considerable research has documented that successful performance in interceptive tasks (such as return of serve in tennis) is based on the performers’ capability to capture appropriate anticipatory information prior to the flight path of the approaching object. Athletes of higher skill tend to fixate on different locations in the playing environment prior to initiation of a skill than their lesser skilled counterparts. The purpose of this study was to examine visual search behaviour strategies of elite (world ranked) tennis players and non-ranked competitive tennis players (n = 43) utilising cluster analysis. The results of hierarchical (Ward’s method) and nonhierarchical (k means) cluster analyses revealed three different clusters. The clustering method distinguished visual behaviour of high, middle-and low-ranked players. Specifically, high-ranked players demonstrated longer mean fixation duration and lower variation of visual search than middle-and low-ranked players. In conclusion, the results demonstrated that cluster analysis is a useful tool for detecting and analysing the areas of interest for use in experimental analysis of expertise and to distinguish visual search variables among participants’.  相似文献   

本土制造企业低端颠覆的理论与案例研究     

杨桂菊  陈思睿  王彤 《科研管理》2020,41(3):164-173

处于后发劣势的本土制造企业,已经很难通过跟随和模仿创新实现赶超。快速变化的技术环境和丰富多样的市场需求,为本土制造企业提供了颠覆赶超的机会。但已有研究对颠覆性创新实现过程与机理的研究较为匮乏。通过对小米公司的探索性案例研究,构建了本土制造企业实现颠覆性创新的理论模型。模型表明：基于非主流的低端市场、利基市场的市场定位颠覆,差异化的服务设计颠覆以及运营模式颠覆是本土制造企业颠覆主流市场在位企业,实现成功赶超的有效模式。知识搜索（同行搜索和跨界搜索）是本土制造企业实施颠覆性创新的知识与信息来源,机会能力是本土制造企业通过知识搜索实现颠覆性创新的核心能力。  相似文献   

论奇观电影     

杨学森 《鸡西大学学报》2011,11(8):111-112

随着现代科技的迅猛发展,一种新的电影样式——奇观电影出现了。奇观电影的出现主要来自两个转变,即传统印刷媒介向现代电子媒介的转变和传统叙事电影向现代奇观电影观念的转变。总体说来,当代奇观电影主要有三种类型：身体奇观,速度奇观,场景奇观。奇观电影一方面给消费时代的受众群体以极大的视觉满足,但另一方面却削弱了传统电影以人类的终极关怀为中心的思想深度。  相似文献   

物流配送的优化模型及算法在连锁企业中应用     

朱晓锋  蔡延光 《顺德职业技术学院学报》2011,9(1):14-17

通过将连锁企业的实际物流配送网络描述为由配送中心和门店两类节点构成的完全无向图,建立0—1整数规划的物流配送路径优化模型。该模型属于一类改进的多车型车辆路径优化模型,是NP难问题,模型充分考虑到不同类型车辆启动费用的不同和所配送商品的多样性、车辆数限制等特性,与实际相吻合,具有很强的实际应用价值。为求解上述模型,设计禁忌搜索算法对模型进行求解,通过仿真实例计算取得了满意的结果。  相似文献
