Emotion regulation has potent influences on multiple domains (e.g., cognitive, psychological) for adaptive human development. Adolescence provides a powerful opportunity to test and advance theories in emotion system and its regulation, as adolescents experience substantial changes at biological, cognitive, psychological, and social levels. In addition to contributing to basic knowledge on emotion and cognitive development, because adolescents are at greater risk for maladjustment and psychopathology, a rigorous understanding of the dynamics of their emotions and its regulation also has clear downstream implications for societal and health policies. Emotion and its regulation involve dynamic within-person processes happening in daily life that cannot be fully captured by conventional designs. Recent technological advances (e.g., smartphone) offer an opportunity to circumvent these obstacles and to collect data with great flexibility and convenience through innovative designs (e.g., daily diary design). Consequently, with advanced statistical modeling, I can investigate emotion as a dynamical system, to illuminate its dynamics as the emotion processes unfold continuously in daily life, and to delineate its links with cognitive and other systems. The long-term goal of this proposed research program is to study adolescent emotion dynamics at day-to-day level, particularly to capture individual-level dynamics and individual differences in daily emotion dynamics, by collecting month-long daily diary data. I aim to unravel the intrinsic dynamics of adolescent daily emotion processes, as well as external factors (e.g., parents' daily emotions) that may influence the emotion system. I will elucidate genetic and environmental origins of daily emotion dynamics by comparing the similarity in emotion dynamics between identical and fraternal twin pairs. Moreover, I will follow adolescents longitudinally over multiple years to illustrate emotion dynamics at different timescales (e.g., days vs. years), to understand its change over longer time period, and to examine its links with long-term outcomes. One major novelty of this research program is to investigate emotion as a dynamical system in real life with the application of state-of-the-art statistical modeling technique. This research program will advance our understanding of emotion dynamics at multiple timescales, and produce novel knowledge of intrinsic and extrinsic determinants of emotion dynamics in daily emotion systems. Besides the development and dissemination of advanced statistical methods, the expected outcomes may form the basis of future research with implications for societal and health policies. For example, community service organizations can incorporate research findings into service programs to target maladaptive adolescent emotion dynamics. Therefore, the research findings can potentially prevent adverse outcomes and promote well-being of adolescents, benefiting all Canadian families.

情绪调节对多个领域具有强大的影响（例如，认知的、心理的）适应性人类发展。青春期为检验和推进情绪系统及其调节理论提供了一个强有力的机会，因为青少年在生物，认知，心理和社会层面上经历了实质性的变化。除了有助于了解关于情绪和认知发展的基本知识外，由于青少年更容易出现适应不良和精神病理学，因此，严格了解他们的情绪动态及其调节也对社会和卫生政策具有明确的下游影响。情绪及其调节涉及日常生活中发生的动态人内过程，无法通过传统设计完全捕获。最近的技术进步（例如，智能手机）提供了绕过这些障碍并通过创新设计（例如，每日日记设计）。因此，通过先进的统计建模，我可以将情绪作为一个动态系统进行研究，阐明情绪过程在日常生活中不断展开的动态，并描绘出它与认知和其他系统的联系。本研究计划的长期目标是通过收集长达一个月的日常日记数据，研究青少年日常情绪动态，特别是捕捉个人水平的动态和日常情绪动态的个体差异。我的目标是揭示青少年日常情绪过程的内在动力，以及外部因素（例如，父母的日常情绪），这可能会影响情绪系统。我将通过比较同卵双胞胎和异卵双胞胎之间情绪动力学的相似性，阐明日常情绪动力学的遗传和环境起源。此外，我将纵向跟踪青少年多年，以说明不同时间尺度的情绪动态（例如，天与年），了解其在较长时间内的变化，并检查其与长期结果的联系。本研究计划的一个主要新奇之处是将情绪作为一个动态系统在真实的生活中应用最先进的统计建模技术。这项研究计划将推进我们对多个时间尺度上的情绪动态的理解，并产生日常情绪系统中情绪动态的内在和外在决定因素的新知识。除了开发和传播先进的统计方法外，预期结果可能构成未来研究的基础，对社会和卫生政策产生影响。例如，社区服务组织可以将研究结果纳入服务计划，以针对适应不良的青少年情绪动态。因此，研究结果可能会防止不良后果，促进青少年的福祉，使所有加拿大家庭受益。
