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合作的研究计划，该计划旨在回答一个基本问题：自主生理学，认知和行为如何在真实的时间内协调，以及这些过程如何在青春期的关键时期发展（即，在多个时间尺度上的一致性动态）？为了做到这一点，我们记录和分析青少年在各种压力和非压力情况下的交感神经唤醒，副交感神经活动，表达行为和认知评价之间的秒的协调互动。这项研究需要对这些组成部分进行综合和同步记录，以便进行高层次分析，揭示整个发展过程中的动态模式。然而，该综合系统现已使用15年，已经过时，需要最新的设备来更换故障部件，并保持与个人电脑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。** 我们申请资金用于：（1）一个记录系统，提供必要的组件，以便能够同时记录最多3名参与者的心电图、皮肤电导和呼吸，并与3个视频流同步（每位参与者一个）。记录系统还允许参与者输入（例如，正在进行的认知评估）与生理和视频记录同步。(2)用于处理和分析这些密集的实时数据的分析系统：生理数据清理和处理以及用于创建行为时间序列的观察编码系统。(3)一个完全集成的备份系统，用于存储从该系统中激增的TB级数据文件，这是我们蓬勃发展的研究计划的一部分。*自2010年以来，在两项NSERC发现赠款的支持下，我们目前的系统已经支持了18篇本科论文，9篇硕士论文和5篇博士论文，还为100多名研究助理提供培训，并在大学和世界各地促进了数十项合作。这一基础设施支持多元化和包容性的HQP，其中几乎所有人都是女性，她们接受最高水平的培训，以支持其蓬勃发展的职业生涯。这项研究计划的影响是非常强大的，它正在加速。此外，这种影响包括合作者和HQP在实验室，部门，在大学，在加拿大，和世界各地。所要求的设备对于确保我们能够超越我们迄今为止所取得的成就，提供对青少年社会情感发展和功能的独特见解至关重要，这是一个对整个社会极为关注的领域，但我们对此的理解却严重不足。**

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. **
