为了探讨符合高职高专特点的英语教学设计策略,通过选择08护理专业班级的学生为实验班级,同级的医用仪器专业班级为对照组。对实验班级采用情景认知理论进行英语教学,对照组采用传统英语教学方法。半年后,对比实验组和合对照组的英语学习情况。结果表明,实验组比对照组的课堂气氛活跃,学习积极性高涨,教学效果好,平均成绩显著提高。说明针对当前高职高专英语教学中存在的主要问题,以情境认知理论为指导,通过创设真实的或“接近”真实的英语认知情境,有助于帮助学生构建自己的认知结构。  相似文献   

Thinking about technology: Applying a cognitive lens to technical change     

Sarah Kaplan  Mary Tripsas 《Research Policy》2008,37(5):790-805

We apply a cognitive lens to understanding technology trajectories across the life cycle by developing a co-evolutionary model of technological frames and technology. Applying that model to each stage of the technology life cycle, we identify conditions under which a cognitive lens might change the expected technological outcome predicted by purely economic or organizational models. We also show that interactions of producers, users and institutions shape the development of collective frames around the meaning of new technologies. We thus deepen our understanding of sources of variation in the era of ferment, conditions under which a dominant design may be achieved, the underlying architecture of the era of incremental change and the dynamics associated with discontinuities.  相似文献   

旅游目的地形象的符号隐喻关联研究     

白凯  孙天宇  谢雪梅 《资源科学》2008,30(8):1184-1190

旅游目的地形象是典型的标志化符号,它用特殊设计过的文字或图形组成来表达旅游目的地的特定含义。本文从游客认知角度,以陕西旅游形象为研究内容,提出了旅游目的地形象符号隐喻关联的假设。对该研究假设的实证调查问卷分析显示,兵马俑是游客最为倾心的陕西旅游视觉符号代表;“秦皇汉武,盛世长安”是陕西旅游形象游客评价的最佳文字表述符号(旅游宣传口号)。以此为基准,对陕西旅游视觉标志符号和文字表述符号进行了隐喻内涵的关联分析,结果表明,陕西旅游形象符号的视觉形体和语言形体存在着正相关(相关系数为0.145),旅游形象符号的视觉形体和该视觉形体引发的符号隐喻存在正相关(相关系数为0.240),陕西旅游形象符号的语言形体和该语言形体所引发的符号隐喻均存在正相关关系(相关系数为0.127)。通过社会人口结构特对研究数据的二次检验不仅证明了上述3种正相关关系的存在,其细化结果也显示出：男性通过实体旅游目的地形象和语言而引发的认知联想明显高于女性;社会科学学习背景的个体通过实体旅游目的地形象和语言而引发的认知联想明显高于自然科学学习背景的个体。  相似文献   

Cardiorespiratory and muscular fitness associations with older adolescent cognitive control

Background:Participation in physical activity supports greater cardiorespiratory fitness(CRF),a correlate of cognitive control.However,the relationship between muscular fitness(MF)and cognitive control is less clear.The present study investigated the differential relationship of CRF and MF with cognitive control in older adolescents.Methods:This cross-sectional study involved students(15
17 years old,n=541,43%female)from 20 secondary schools who completed tests of inhibition(modified flanker task),working memory(n-back task),CRF(Progressive Aerobic Cardiovascular Endurance Run),and MF(standing long jump and push-up test).Multilevel analyses tested the association between CRF or MF and cognitive outcomes while accounting for the influence of the other fitness variable and relevant demographic factors.Results:CRF predicted response accuracy during incongruent flanker trials,the condition requiring greater inhibition.For the working memory task,CRF predicted greater target accuracy and greater d’scores on the 1-back task,requiring lesser amounts of working memory.In the 2-back task,which requires greater amounts of working memory,CRF also predicted greater target and non-target accuracy and d’scores.Comparatively,MF did not predict any cognitive outcomes after adjustment for CRF.Conclusion:CRF was selectively related to better performance during task conditions that require greater amounts of inhibition and working memory.This finding suggests that CRF,but not MF,may benefit cognitive control in older adolescents.This selective influence of CRF on older adolescents’cognition highlights the value of aerobic physical activity.  相似文献

Does exercise have a protective effect on cognitive function under hypoxia? A systematic review with meta-analysis

ObjectiveThis study aimed to examine (1) the independent effects of hypoxia on cognitive function and (2) the effects of exercise on cognition while under hypoxia.MethodsDesign: Systematic review with meta-analysis. Data sources: PubMed, Scopus, Web of Science, PsychInfo, and SPORTDiscus were searched. Eligibility criteria for selecting studies: randomized controlled trials and nonrandomized controlled studies that investigated the effects of chronic or acute exercise on cognition under hypoxia were considered (Aim 2), as were studies investigating the effects of hypoxia on cognition (Aim 1).ResultsIn total, 18 studies met our inclusionary criteria for the systematic review, and 12 studies were meta-analyzed. Exposure to hypoxia impaired attentional ability (standardized mean difference (SMD) = –0.4), executive function (SMD = –0.18), and memory function (SMD = –0.26), but not information processing (SMD = 0.27). Aggregated results indicated that performing exercise under a hypoxia setting had a significant effect on cognitive improvement (SMD = 0.3, 95% confidence interval: 0.14 – 0.45, I² = 54%, p < 0.001). Various characteristics (e.g., age, cognitive task type, exercise type, exercise intensity, training type, and hypoxia level) moderated the effects of hypoxia and exercise on cognitive function.ConclusionExercise during exposure to hypoxia improves cognitive function. This association appears to be moderated by individual and exercise/hypoxia-related characteristics.  相似文献   

隐喻、认知、翻译、交流     

蒋荣丰 《毕节学院学报》2005,23(1):56-58

从隐喻的基本概念和翻译的性质、任务以及翻译和隐喻的关系着手,探讨了隐喻和翻译的共性,信息交流过程中隐喻对翻译的影响,说明了翻译过程中隐喻问题的探讨是十分必要和有意义的.在英汉隐喻互译中,译者应力求沟通不同文化的人群对事物的认知,求同存异,增进读者对异语文化的了解,促进不同文化人群间的交流,实现信息的准确传递.  相似文献
