Integrated Psychophysiology and Observational System for Synchronous Measurement and Analysis

所要求的设备支持一个充满活力和高度协作的研究计划，该计划寻求回答一个基本问题：自主生理、认知和行为如何实时协调，以及这些过程如何在青春期的关键时期(即，多个时间尺度上的和谐动态)发展？为此，我们记录和分析了青少年在各种压力和非压力环境中交感唤醒、副交感活动、表达行为和认知评估之间的一秒又一秒的协调互动。这项研究需要对这些组件进行集成和同步记录，以便进行高级分析，揭示整个开发过程中的动态模式。然而，集成系统现在已有15年的历史，已经过时，需要最新的设备来更换故障部件，并保持与PC硬件和操作系统的兼容性。在两年内，如果没有安装所需的组件，研究计划将陷入停顿。*我们请求资金用于：(1)一个记录系统，提供必要的组件，能够同时记录多达3名参与者的心电、皮肤电导和呼吸，并与3个视频流(每个参与者1个)同步。记录系统还允许与生理和视频记录同步的参与者输入(例如，正在进行的认知评估)。(2)处理和分析这些密集、实时数据的分析系统：生理数据清理和处理以及创建行为时间序列的观测编码系统。(3)作为我们蓬勃发展的研究计划的一部分，该系统为从该系统产生的TB级数据文件建立了完全集成的备份系统。*自2010年以来，在两项NSERC Discovery拨款的支持下，我们目前的系统已经支持了18篇本科生论文、9篇硕士论文和5篇博士论文，还为100多名研究助理提供了培训，并促进了大学内部和世界各地的数十项合作。这一基础设施支持一系列多样化和包容性的HQP，几乎所有HQP都是妇女，她们接受了最高水平的培训，以支持她们蓬勃发展的职业生涯。这一研究计划的影响非常强烈，而且正在加速。此外，这种影响包括实验室、系、大学、加拿大和世界各地的合作者和HQP。所要求的设备对于确保我们能够超越我们迄今所取得的成就，为青少年的社会情绪发展和功能提供独特的见解是至关重要的，这是整个社会极为关切的一个领域，但我们对此了解严重不足。**

The equipment requested supports a vibrant and highly-collaborative research program that seeks to answer a fundamental question: How do autonomic physiology, cognitions, and behaviour coordinate in real time and how do these processes develop across the critical period of adolescence (i.e., the dynamics of concordance at multiple time scales)? To do so, we record and analyze adolescents' second-by-second coordinated interactions among sympathetic arousal, parasympathetic activity, expressive behaviour, and cognitive appraisals during various stressful and non-stressful circumstances. This research requires integrated and synchronized recording of these components for high-level analyses revealing dynamic patterns across development. However, the integrated system is now 15 years old, obsolete and requiring up-to-date equipment to replace failing parts and to maintain compatibility with PC hardware and operating systems. Within 2 years, the research program will grind to a halt if the requested components are not installed. ******We request funds for: (1) a recording system to provide the necessary components to be able to record electrocardiogram, skin conductance, and respiration from up to 3 participants simultaneously, synchronized with 3 video streams (one per participant). The recording system also allows for participant input (e.g., ongoing cognitive appraisals) synchronized with the physiological and video recordings. (2) an analysis system for processing and analyzing these dense, real-time data: physiological data cleaning and processing as well as the observational coding system to create behavioural time series. (3) a fully integrated back-up system for the terabytes of data files that proliferate from this system as part of our thriving research program.******Supported by two NSERC Discovery grants since 2010, our current system has supported 18 undergraduate theses, 9 Master's theses, and 5 PhD dissertations, also providing training for over 100 research assistants, and fostering dozens of collaborations within the university and across the world. This infrastructure supports a diverse and inclusive range of HQP, almost all of whom have been women, who receive the highest level of training to support their burgeoning careers. The impact of this research program is very strong and it is accelerating. Moreover, this impact includes collaborators and HQP in the lab, the department, at the university, across Canada, and around the world. The requested equipment is vital for making sure that we can push beyond what we have accomplished so far to provide unique insights into adolescent socioemotional development and functioning, an area of dire concern for society as a whole but for which we have woefully inadequate understanding. **
