当前的研究检验了武器聚焦效应是否可以用刺激新颖性来解释。参与者在执行次要任务时观看了模拟事件的幻灯片。在关键幻灯片中，目标显示持有威胁物体（武器状态）、新颖物体（异常状态）或中性物体（控制状态）。在武器和异常条件下，次要任务的反应时间会受到影响。当考虑到置信度时，武器条件下的参与者对目标外观的识别得分最差。结果表明，虽然不寻常和具有威胁性的物体都会引起注意，但武器的重要性可能会导致场景中不太直接的信息方面（例如目标外观）的表现受损。
The current study examined whether the weapon focus effect could be accounted for in terms of stimulus novelty. Participants viewed a slideshow of a simulated event while attending to a secondary task. In the critical slide, the target was shown holding a threatening object (weapon condition), a novel object (unusual condition) or a neutral object (control condition). Reaction times on the secondary task were impaired in the weapon and unusual conditions. Participants in the weapon condition had poorest recognition scores for the target's appearance when confidence was also taken into account. Results suggest that while both unusual and threatening objects command attention, the significance of a weapon can lead to impaired performance on less immediately informative aspects of a scene such as target appearance.
