The influence of mental fatigue on functional perception-action coupling during skill acquisition

构建学习环境和活动，使表演者能够保留他们练习的技能，并能够在不同的情况和压力条件下执行复杂的技能，这在许多领域（例如，体育和急救人员）都是一个挑战。特别是，我们对情感状态（如感觉、情绪和情绪）如何影响感知和运动技能获得的基本知识存在重大差距。了解情感状态如何影响获得专业表现的技能，可以显著改善我们训练一系列表演者和专业人士的方式。因此，我的研究项目的长期目标是改进基于证据的建议和应用工具，以构建情感学习环境和活动，以优化技能习得。短期目标侧重于解决当前与特定类型的情感相关的差距，即精神疲劳及其对表现和学习的影响：1)研究精神疲劳如何影响运动技能、感知技能和感觉运动校准的习得。2)研究情感状态如何与任务和个体特征相互作用以调节或缓和心理疲劳的影响。我的实验室的具体研究方法包括一系列的实验室研究，调查精神疲劳如何影响感知和运动技能的表现和学习。这些研究将评估练习和表现约束，如任务特异性、复杂性和自主程度，如何与心理疲劳对功能性感知-行动配对和感知-运动学习的影响相互作用（目标1）。我们还将评估性别、技能水平和一般认知功能等因素如何调节或调节精神疲劳对感知运动学习的影响（目标2）。我提出的研究计划将产生短期和长期的结果：a)有助于我们对精神疲劳及其对感知过程的影响的基本理解，例如感觉运动（重新）校准，表现和感知运动技能的获得，同时b)同时促进从业者和表演者的知识转移。我的研究计划的另一个目标是在应用运动学习领域培养高素质的学员，他们将在高度协作的实验室研究环境中工作，并获得与实践者合作并将其研究成果转化为实践者的经验。开发更好的模型和理解情感状态（如精神疲劳）是如何影响学习和表现的，这是该领域的一个令人兴奋的进步，也是朝着能够优化学习环境以培养专家表演者这一长期目标迈出的重要一步。

Structuring learning environments and activities so that performers are able to retain the skills they practice, and be able to execute complex skills under varying situation and pressure conditions, is a challenge in many domains (e.g., sport and first responders). In particular, there are significant gaps in our fundamental knowledge of how affective states (e.g., feelings, emotions, and mood), influence the acquisition of perceptual and motor skills. Understanding how affective states influence the acquisition of skills that underpin expert performance can significantly improve how we train a range of performers and professionals. As such, the long-term goal of my research program is to improve evidence-based recommendations and applied tools for structuring affective learning environments and activities to optimize skill acquisition. The short-term objectives focus on addressing current gaps related to a specific type of affect, i.e. mental fatigue, and its influences on performance and learning: 1) Examining how mental fatigue influences the acquisition of motor skills, perceptual skills, and sensorimotor calibration. 2) Examining how affective states interact with task and individual characteristics to mediate or moderate the influence of mental fatigue. My lab's specific research approach involves a series of laboratory studies investigating how mental fatigue influences performance and learning of perceptual and motor skills. These studies will evaluate how practice and performance constraints, such as task specificity, complexity and degree of autonomy, interact with the influence of mental fatigue on functional perception-action pairings and perceptual-motor learning (Objective 1). We will also evaluate how factors such as sex, and skill level and general cognitive function moderate or mediate the influence of mental fatigue on perceptual-motor learning (Objective 2). My proposed research program will produce both short- and long-term outcomes that: a) contribute to our fundamental understanding of mental fatigue and its influence on perceptual processes, such as sensorimotor (re)calibration, performance, and the acquisition of perceptual-motor skill, while b) concurrently facilitating knowledge transfer of evidence for practitioners and performers. Another goal of my research program is to produce highly qualified trainees in the field of applied motor learning, who will work in a highly collaborative laboratory-based research environment, and gain experience working with and translating their research to practitioners. Developing better models and understanding of how affective states like mental fatigue influence learning and performance represents an exciting advancement in the field, and is an important step toward the long-term goal of being able to optimize learning environment for the development of expert performers.
