We explored how varying levels of professional expertise in hostile crowd management could enhance threat detection capabilities as assessed by the face in the crowd paradigm. Trainee police officers and more experienced police officers specialized in, and having extensive experience with, riot control, were compared with participants with no experience in hostile crowd management on their search times and accuracy levels in detecting angry and happy face targets against a display of emotional and neutral distractor faces. The experienced officers relative to their trainee counterparts and nonpolice controls showed enhanced detection for threatening faces in both types of display along with a greater degree of inhibitory control over angry face distractors. These findings help to reinforce the ecological validity of the face in the crowd paradigm and provide a new theoretical link for the role of individual differences on the attentional processing of socially relevant stimuli.
我们探讨了在人群中管理敌对人群方面不同水平的专业知识如何增强威胁检测能力，这一能力通过人群中的面孔范式进行评估。将实习警察以及专门从事防暴控制并拥有丰富经验的经验更丰富的警察，与在管理敌对人群方面没有经验的参与者在检测愤怒和高兴面孔目标时的搜索时间和准确率进行了比较，这些目标呈现于情绪化和中性干扰面孔之中。相对于实习警察和非警察对照组，经验丰富的警察在两种显示类型中对威胁性面孔的检测能力增强，并且对愤怒面孔干扰物具有更强的抑制控制能力。这些发现有助于加强人群中的面孔范式的生态效度，并为个体差异在社会相关刺激的注意力加工中的作用提供新的理论联系。
