Abstract

We compared shoot/don't shoot task (SDST) performance in law enforcement officers (LEOs) and non-officers under normal cognitive load, and under higher load induced by processing a complex dispatch message. We also examined the effects of participants' behavioural activation (BAS) and inhibition (BIS) systems, impulsivity, and working memory on SDST performance. Stimuli were videos of shoot and don't shoot variations performed by three actors. Dependent measures were shoot errors, fail-to-shoot errors, response time, and shooting accuracy. Compared to non-officers, LEOs were more accurate and adapted to make fewer fail-to-shoot errors. They were not faster, and did not make fewer shoot errors. Compared to normal cognitive load, under higher load, participants were quicker and more accurate, but made more shoot errors. The higher cognitive load condition revealed effects that were not present under normal load. Participants making more shoot errors had higher BAS, and BIS than those making fewer or no errors.

强化敏感性、冲动性和工作记忆对普通和高认知负荷下执法人员和平民开枪/不开枪行为的影响

我们比较了执法人员和非执法人员在正常认知负荷和处理复杂调度信息导致的更高认知负荷下的SDST表现。我们还研究了参与者的行为激活（BAS）和抑制（BIS）系统、冲动性和工作记忆对SDST表现的影响。刺激是由三个演员表演的拍摄和不拍摄变化的视频。相关测量包括射击误差、射击失败误差、反应时间和射击精度。与非军官相比，leo更准确，适应更少的失败射击错误。他们没有更快，也没有犯更少的投篮错误。与正常认知负荷相比，高负荷下的射击速度更快、更准确，但射击错误更多。高认知负荷条件显示出正常负荷下不存在的效应。投篮失误多的参与者比投篮失误少或没有失误的参与者有更高的BAS和BIS。

期刊介绍： Ergonomics, also known as human factors, is the scientific discipline that seeks to understand and improve human interactions with products, equipment, environments and systems. Drawing upon human biology, psychology, engineering and design, Ergonomics aims to develop and apply knowledge and techniques to optimise system performance, whilst protecting the health, safety and well-being of individuals involved. The attention of ergonomics extends across work, leisure and other aspects of our daily lives. The journal Ergonomics is an international refereed publication, with a 60 year tradition of disseminating high quality research. Original submissions, both theoretical and applied, are invited from across the subject, including physical, cognitive, organisational and environmental ergonomics. Papers reporting the findings of research from cognate disciplines are also welcome, where these contribute to understanding equipment, tasks, jobs, systems and environments and the corresponding needs, abilities and limitations of people. All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymous refereeing by independent expert referees.
