Collaborative Research: Multifrequency Coordination in Dyads and Teams

人们在许多不同的环境中以许多不同的方式相互协调行动：交通中的司机设法在没有发生事故的情况下合并；人们走在拥挤的街道上通常会避免事故；音乐家协调乐队成员产生的各种嵌套节奏。这些例子突出了人类协调行为和以不同速度交换信息以实现总体目标的能力，这种现象称为人际多频协调。研究人员将通过将耦合振荡器系统的物理学应用于这种类型协调中固有的感知、认知和社会信息来研究人与人之间的多频协调。一对对参与者（二人组）将通过耳机聆听不同节拍器频率的同时协调他们的动作。性能模式和模式稳定性将在不同的实验条件下进行测量，以测试数学模型的基本预测。在知觉（如视觉）、认知（如计数）和社会（如伙伴熟悉度）耦合机制的背景下，专门设计用于增加或减少成对运动之间耦合的实验操作将进行测试。还计划进行实地研究，以发现人们在自然情况下如何协调。这一系列的研究旨在推进对多频协调的基础研究，并将该研究扩展到更大团队的自发协调。这个项目的一个重要方面是将实验室中实验诱导的多频协调扩展到现实世界中，在现实世界中，自发的多频协调发生在个人团队中。该项目还有一个重要的外展组成部分，包括访问一个全国组织的竞争性青年夏令营，在那里调查人员将收集自发人际关系、多频协调的数据，并向营员讲授协调科学和STEM领域的知识。

People coordinate their actions with one another in many different contexts and in many different ways: Drivers in traffic manage to merge without accident; people walking on crowded streets usually avoid mishap; musicians coordinate a variety of nested rhythms produced by band members. These examples highlight the human capacity to coordinate behavior and exchange information at different rates to accomplish an overall goal, a phenomenon called interperson, multifrequency coordination. The researchers will study interperson, multifrequency coordination by applying the physics of coupled, oscillator systems to the perceptual, cognitive, and social information inherent in this type of coordination. Pairs of participants (dyads) will coordinate their movements while listening to different metronome frequencies through headphones. Both performance pattern and pattern stability will be measured under different experimental conditions in order to test fundamental predictions of the mathematical model. Experimental manipulations specifically designed to increase or decrease coupling between dyads' movements will be tested in the context of perceptual (e.g., visual), cognitive (e.g., counting), and social (e.g., partner familiarity) coupling mechanisms. Field studies are also planned to discover how people coordinate in naturalistic situations. This sequence of studies is designed to advance basic research on multifrequency coordination in dyads and to extend that research to spontaneous coordination in larger teams.One important aspect of this project is the extension of experimentally induced multifrequency coordination in the laboratory to real-world settings in which spontaneous multifrequency coordination occurs across teams of individuals. The project also has a significant outreach component, including a visit to a nationally organized competitive youth summer camp, where investigators will collect data on spontaneous interperson, multifreqency coordination and teach campers about coordination science and STEM fields.
