Even at subclinical levels, anxiety and depression are associated with impaired cognitive control. It is unclear, though, to what extent these deficits reflect a common underlying dysfunction. Using a non-affective hybrid masked prime-Simon task, we obtained several measures of within- and between- trial inhibitory behavioral control in 80 young, healthy volunteers, together with measures of their anxiety and depression levels. Neither depression nor anxiety affected low-level within-trial control, or any of the between-trial control measures. However, increased levels of depression, but not of anxiety, were associated with impaired high-level within-trial control (increased Simon effect). Results indicate that depression, but not anxiety, impairs voluntary online response-control mechanisms independent of affective content.
即使在亚临床水平，焦虑和抑郁也与认知控制受损有关。然而，目前尚不清楚这些缺陷在多大程度上反映了一种共同的潜在功能障碍。我们使用非情感混合掩蔽启动-西蒙任务，对80名年轻健康志愿者进行了多项试验内和试验间抑制行为控制的测量，同时测量了他们的焦虑和抑郁水平。抑郁和焦虑均未影响低水平的试验内控制或任何试验间控制指标。然而，抑郁水平的升高而非焦虑水平的升高与高水平的试验内控制受损（西蒙效应增加）有关。结果表明，抑郁而非焦虑会损害独立于情感内容的自愿在线反应控制机制。
