目前的研究调查了睡眠剥夺和咖啡因的使用对开枪决定中的种族偏见的影响。被剥夺24小时睡眠的参与者（与休息的参与者相比）在射击任务中犯了更多的错误，更有可能射击手无寸铁的目标。一项扩散决策模型分析显示，睡眠剥夺降低了参与者从刺激中提取信息的能力，而咖啡因影响了阈值分离，反映了谨慎度的降低。睡眠剥夺和咖啡因都不能缓和射击决策或过程层面的反黑人种族偏见。我们讨论了我们的结果如何澄清过去工作的差异，测试疲劳对射击决策中的种族偏见的影响。
The current study examines the effect of sleep deprivation and caffeine use on racial bias in the decision to shoot. Participants deprived of sleep for 24 hr (vs. rested participants) made more errors in a shooting task and were more likely to shoot unarmed targets. A diffusion decision model analysis revealed sleep deprivation decreased participants' ability to extract information from the stimuli, whereas caffeine impacted the threshold separation, reflecting decreased caution. Neither sleep deprivation nor caffeine moderated anti-Black racial bias in shooting decisions or at the process level. We discuss how our results clarify discrepancies in past work testing the impact of fatigue on racial bias in shooting decisions.
