A critical cognitive symptom that is commonly involved in social anxiety and depression is attentional deficit. However, the functional relationship between attentional deficit and these two disorders remains poorly understood. Here, we behaviorally disentangled the three key attentional components (alerting, orienting, and executive control) using the established attentional network task (ANT) to investigate how social anxiety and depression are related to deficits in these attention components. We identified a double dissociation between the symptoms of social anxiety and depression and the attentional component deficits when processing non-emotional stimuli. While individuals vulnerable to social anxiety exhibited deficits in the orienting component, individuals vulnerable to depression were impaired in the executive control component. Our findings showed that social anxiety and depression were associated with deficits in different attentional components, which are not specific to emotional information.
注意力缺陷是社交焦虑和抑郁中常见的认知症状，但目前人们对其与这两种疾病之间的功能关系仍知之甚少。在这里，我们使用已建立的注意网络任务（ANT）从行为上分离了三个关键的注意力成分（警觉、定向和执行控制），以研究社交焦虑和抑郁与这些注意力成分缺陷之间的关系。我们发现，在处理非情感刺激时，社交焦虑和抑郁的症状与注意力成分缺陷之间存在双重分离。虽然易患社交焦虑的个体在定向成分上存在缺陷，但易患抑郁的个体在执行控制成分上存在缺陷。我们的研究结果表明，社交焦虑和抑郁与不同的注意力成分缺陷有关，而这些缺陷与情绪信息无关。
