EDP Informational-Frames Study

The study was designed to examine whether informational frames preceding police officer-civilian confrontation videos can influence how participants perceive the video and ultimately make decisions about the officer’s use of force. Two types of informational frames were examined in the present study: civilian EDP- and police warning-informational frames. Experiment 1 examined whether civilian EDP-informational frames affected judgments of police use of force. Information about the civilian in the video was varied: participants were either informed the civilian had a substance abuse issue, mental illness, or nothing (no EDP control). Experiment 2 examined whether civilian EDP- and police warning-informational frames influenced judgments of police use of force. Participants were either told the officer was informed about the civilian’s behavior, the officer was not informed about the civilian’s behavior, or nothing.

本研究旨在探究警官-平民对峙视频前的信息框架，是否会影响参与者对视频的感知，并最终影响其对警方使用武力的决策判断。本研究共考察两类信息框架：平民EDP信息框架与警方预警信息框架。
实验1旨在探究平民EDP信息框架是否会影响参与者对警方使用武力的评判。研究中对视频中平民的相关信息设置了变量条件：参与者将分别被告知平民存在物质滥用问题、精神疾病，或无相关背景信息（EDP对照组）。
实验2则探究平民EDP与警方预警两类信息框架，是否会对参与者关于警方使用武力的评判产生影响。参与者被分为三组，分别被告知警员已获悉平民的行为情况、警员未获悉平民的行为情况，以及无相关背景信息。
