Abstract

Previous research on police officer shoot decisions has focussed on the influence of situational factors that lead to the shooting error. Focussing instead on the 'shooter', the present study examined whether working memory capacity and threat-related increases in negative emotionality influenced participant shoot decisions in a simulated shooting task. Following a working memory test, 24 police officers viewed a police-relevant threatening video while physiological indices of arousal and negative affect were obtained and then completed a computerized shoot-don't shoot task. Results indicated that lower working memory capacity was associated with a greater likelihood of shooting unarmed targets and a failure to shoot armed targets. Moreover, an interaction effect indicated that these associations were only significant for officers who experienced heightened negative emotionality in response to the video. Results suggest that when negatively aroused via threat, limited working memory capacity increases the risk of shooting error. Copyright © 2009 John Wiley & Sons, Ltd.
