The present study explored the impact of publicized incidents of police violence on racially underrepresented college students in the U.S. Approximately 134 college students at various colleges and universities in the U.S. completed a questionnaire that examined their engagement with police brutality videos, reactions about police killings of unarmed Black men (and boys), their encounters with police, and perceptions toward the issue of police violence. The majority of participants were students of color, from the middle to high socioeconomic backgrounds and attended private and public institutions of higher education. The main findings included: (1) social media as a medium to learn about incidents of police violence; (2) students displayed symptoms consistent with post-traumatic stress disorder (i.e., anger, sadness, and fear) after viewing the videos; and (3) student’s race affected how they viewed police violence in social media. These findings reflect that witnessing publicized police killings of unarmed Black men (and boys) is traumatic for college students and contributes to anxiety and fear for future police encounters.

“唯一的新鲜事物是照相机”：美国大学生对社交媒体上警察暴力行为的认知研究

本研究探讨了公开的警察暴力事件对美国种族代表性不足的大学生的影响。美国各高校中约有134名大学生完成了一份调查问卷，调查了他们与警察残暴视频的接触，对警察杀害手无寸铁的反应黑人（和男孩），与警察的相遇以及对警察暴力问题的看法。参加者大多数是有色人种，从中级到较高的社会经济背景，并参加了私立和公共高等教育机构。主要研究结果包括：（1）社交媒体作为了解警察暴力事件的媒介；（2）学生表现出与创伤后应激障碍一致的症状（例如，愤怒，悲伤，和恐惧）后，观看视频；（3）学生的种族影响了他们在社交媒体上对警察暴力的看法。这些发现反映出，目击公开的警察杀害手无寸铁的黑人（和男孩）对大学生而言是创伤，并加剧了他们对未来警察遭遇的焦虑和恐惧。
