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

组织学习环境和活动，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)是一项挑战。特别是，在我们对情感状态(例如，感觉、情绪和情绪)如何影响知觉和运动技能的获得的基础知识方面，存在着显著的差距。了解情感状态如何影响支撑专家表现的技能的获得，可以显著改善我们培训一系列表演者和专业人员的方式。因此，我的研究计划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，以优化技能获得。短期目标集中于解决目前与一种特定类型的情感有关的差距，即精神疲劳，及其对表现和学习的影响：1)考察精神疲劳如何影响运动技能、知觉技能和感觉运动校准的获得。2)考察情绪状态如何与任务和个体特征相互作用来调节或调节心理疲劳的影响。我的实验室的具体研究方法包括一系列实验室研究，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绩效限制，如任务的专一性、复杂性和自主性程度，如何与心理疲劳对功能知觉-动作配对和知觉-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中介精神疲劳对知觉-运动学习的影响(目标2)。我建议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了解，如感觉运动(再)校准、操作和感知-运动技能的获得，同时促进从业者和表演者证据的知识转移。我的研究计划的另一个目标是培养应用运动学习领域的高素质实习生，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他们的研究成果转化为实践者的经验。开发更好的模型，了解精神疲劳等情感状态如何影响学习和表现，是该领域令人兴奋的进步，也是朝着能够为专家表演者的发展优化学习环境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.
