During the COVID-19 pandemic, organizers of crowd events must facilitate physical distancing in environments where attendees previously enjoyed being close with ingroup members, encourage accurate perception of health risks and close adherence to safety guidance, and stop expected normative behaviors that may now be unsafe. Research from crowd psychology demonstrates how group processes are integral to each of these issues. The COVID-19 pandemic, however, has created an extreme case environment in which to evaluate the collective findings from previous research and identify future research directions. This paper outlines how organizers of crowd events and researchers can work together to further develop our understanding of social connectedness in crowds, reasons for risk-taking behavior, and level of engagement in new collective behaviors. By working together to address these issues, practitioners and researchers can develop our understanding of crowd processes and improve safety at future crowd events.

在COVID-19大流行期间，人群活动的组织者必须在以前与小组成员保持亲密关系的参与者中促进身体疏远，鼓励对健康风险的准确认识并严格遵守安全指导，并停止可能现在不安全的预期规范行为。人群心理学的研究表明，群体过程是这些问题中不可或缺的一部分。但是，COVID-19大流行已经创造了一个极端的案例环境，可以在其中评估先前研究的总体发现并确定未来的研究方向。本文概述了人群活动的组织者和研究人员如何共同努力，以进一步发展我们对人群中社会联系的理解，冒险行为的原因以及参与新的集体行为的水平。
