Abstract: The research aims to construct an evaluation index system for the training effectiveness of national vocational qualification rock climbing junior instructors through Delphi method, questionnaire survey, mathematical statistics, and expert opinion consultation. The system is based on the Kirkpatrick evaluation model and covers the training preparation, learning, and application period to improve the accuracy of evaluation. By objectively and comprehensively evaluating the training effectiveness of rock climbing instructors, problems and deficiencies in the training process can be identified in a timely manner, so as to improve the training content and methods in a targeted manner and enhance the quality of training. The research successfully established a system consisting of 3 primary indicators (training background, process, and outcome evaluation), 7 secondary indicators, and 17 tertiary indicators, which have been verified to have a positive effect on training effectiveness evaluation. Further use Delphi method and Analytic Hierarchy Process to determine the weight of indicators, establish a comprehensive evaluation model, and divide the training effect into three levels of development potential: high, medium, and low. Empirical research shows that the comprehensive score of the training effect for junior rock climbing instructors in Southwest China in 2023 is S=4.8316, which belongs to a high development potential area and indicates significant training effectiveness. At the same time, the research analyzed the training issues and proposed improvement measures. In summary, the indicator system constructed in this study has high application value for rock climbing training and development, providing strong support for future training work.本研究旨在运用德尔菲法、问卷调查法、数理统计法以及专家意见征询等方法,构建国家职业资格攀岩初级指导员培训效果评价指标体系。该体系以柯式评价模型为基础,涵盖培训准备、学习及应用期,旨在提升评价的准确性。通过对攀岩指导员培训效果进行客观、全面的评价,能够及时发现培训过程中存在的问题和不足,进而有针对性地改进培训内容和方式,提升培训质量。研究成功建立了包含3项一级指标(培训背景、过程、结果评价)、7项二级指标和17项三级指标的体系,经检验,该体系对培训效果评价具有积极作用。进一步采用德尔菲法和层次分析法确定指标权重,建立综合评价模型,将培训效果划分为高、中、低三个发展潜力等级。实证研究表明,西南地区2023年攀岩初级指导员培训效果综合得分S=4.8316,属于高发展潜力地区,表明培训成效显著。同时,研究分析了培训存在的问题并提出改进措施。综上所述,本研究构建的指标体系在攀岩运动培训和发展方面具有较高的应用价值,能够为未来的培训工作提供有力支持。
Abstract: Human emotion plays an important role in our daily life. EEG-based emotion recognition is expected to facilitate our understanding of the neural mechanisms as well as applications of emotion recognition. Most EEG-based emotion recognition studies have employed the classical event-related approach, which may not be the most suitable tool for naturalistic situations with continuous audio-visual emotional information streams.In the present study, we explored emotion recognition using EEG-based inter-subject correlation (ISC) features. ISC measures the consistency of neural responses across a group of participants exposed to identical complex and continuous stimuli, characterizing the neural responses from a multi-person perspective. Using a publicly available EEG-based emotion database named DEAP, in which 32 participants watched 40 video clips with different emotional properties, ISCs over left parietal cortex and frontal region are found to be significantly correlated with arousal ratings and valence ratings, respectively (arousal: r=0.41, p=0.008; valence: r=0.37, p=0.017) . In addition, using ISCs as features, binary classification accuracies for arousal and valence reached 77.5% and 70%, which are superior to the traditional individual spectral power based method (44.1±13.9% and 48.6±12.7%). Our results suggest that the inter-subject correlation approach as an effective and promising candidate for investigating human emotion experiences. 寻找不同情绪状态的脑神经表征,对于情绪的认知神经机制研究与情绪识别等现实应用具有重要意义。现有基于脑电的情绪识别研究方法大多采用经典的事件相关分析方法,难以应用于包含连续视觉—听觉信息的自然情绪刺激情境。本研究探索了多人脑电一致性特征用于情绪识别的效力。多人脑电一致性特征关注多人在同一复杂视听刺激环境下的脑电响应时间过程的相似性,从有别于事件相关方法的多人视角刻画了大脑神经响应特性。研究发现,32名被试观看40段情绪诱发视频时,被试的左侧顶叶及前额叶脑电响应的多人一致性特征分别与主观情绪评分的唤起度和效价有显著相关(唤起度r=0.41,p=0.008;效价r=0.37,p=0.017)。进一步研究发现,基于多人脑电一致性特征对情绪唤起度和效价主观评分高/低的二分类所得正确率分别为77.5%和70.0%,而基于相应的单人脑电特征所得分类正确率仅为随机水平(44.1±13.9%和48.6±12.7%)。本研究结果首次展示了多人脑电一致性特征在情绪识别领域的效力与应用潜力。
