Cognition and Body-Worn Cameras

近年来，警察部门和执法机构大大增加了对穿戴式摄像机（BWC）的使用。然而，对于在法律的制度中使用《生物武器公约》录像的最适当方式，人们知之甚少。一个重要的问题是，在发生使用武力事件后，警察是否应该审查他们的《生物武器公约》录像。由于美国最高法院认为，对官员行为的评价必须基于该官员的原始观点，因此必须了解观看《生物武器公约》录像是否会影响其原始观点。该项目将研究观看某一事件的录像如何影响个人对原始事件的记忆，并将采用实验方法探讨观看某一事件的录像，例如《生物武器公约》的录像，如何影响个人对原始事件的记忆，以及调节这种影响的变量。各种实验将利用警官和平民参与模拟训练和使用武力事件。这些实验将评估控制观看录像对记忆影响的两个不同人群的变量，以确定观看《生物武器公约》录像对记忆影响的具体认知机制。这项以理论为导向、以证据为基础的研究将促进对《生物武器公约》录像对记忆影响的理解，同时帮助执法部门制定与《生物武器公约》有关的政策。该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的知识价值和更广泛的影响审查标准进行评估予以支持。

Cognition and Body-Worn CamerasAbstractPolice departments and law enforcement agencies have greatly increased their use of Body-Worn Cameras (BWCs) in the recent past. However, not much is known about the most appropriate way to use BWC footage in the legal system. One important question is whether police officers should review their BWC footage after a use of force incident. As the U.S. Supreme Court has held that evaluations of an officer's actions must be based on the original perspective of the officer, it is important to understand whether viewing the BWC footage influences that original perspective. This project will study how viewing video footage of an event affects an individual's memory of the original event.This project will employ an experimental approach to address how viewing video footage of an event, such as from a BWC, affects an individual's memory of the original event and the variables that moderate this effect. The various experiments will use police officers and civilian participants in simulations that replicate training and use of force incidents. These experiments will assess variables on two different populations that control for the effect of viewing the video on memory, in order to identify the specific cognitive mechanisms that underlie the effect of viewing BWC footage on memory. This theory-driven and evidence-based research will foster understanding of the effects of BWC footage on memory while aiding law enforcement in developing policies related to BWCs.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
