Cognitive and Affective Precursors to Decisions to use Lethal Force Against Black Suspects: A Virtual Reality Application

Abstract

Here we investigated the role of physiological stress on participants' lethal force decisions with Black suspects using a novel virtual reality (VR) paradigm. We examined the conditional and mediational roles of implicit racism and visual attention to Black suspects. For this study, we filmed a series of high-risk suspect-police interactions with a 360° video camera which, when viewed through the VR headset, embeds the participants in these scenarios from the perspective of a police officer. Embedded eye tracking in the VR enabled assessment of both physiological stress (through pupil dilation) and attention (through gaze location). Analysis of these behavioral data with criminal justice majors (N = 39) revealed a facilitative function of physiological stress for improving accuracy in lethal force decisions, specifically among those with low levels of implicit racism. Findings also indicated that dysregulated attention—characterized by either disorganized or fixated attentional patterns—compromised lethal force decision making. Results are discussed in relation to future applications of VR to inform our understanding of cognitive and affective precursors of poor decision making. Implications include the promise of cognitive-behavioral interventions for mitigating dysregulated attention patterns, ultimately towards the end of reducing unwarranted uses of lethal force against Black men and women.
