以前的研究已经证明了一个特定的认知偏见，目前抑郁症患者的悲伤刺激，很少有人知道，但是，这种偏见是否持续从抑郁发作恢复后。抑郁症在哮喘患者中经常观察到，并且与疾病的恶化过程有关。考虑到这些高的共病率，我们可以预期在哮喘患者中观察到类似的对悲伤刺激的偏倚。因此，我们研究了20名目前和20名以前抑郁的参与者，20名从未抑郁的哮喘患者和20名健康对照参与者的记忆和注意力的认知偏差。所有被试完成三个认知任务：自我参照编码和附带回忆任务、情绪面孔点探测任务和情绪Stroop任务。与健康的参与者相比，目前和以前抑郁的参与者，但不是哮喘患者，表现出特定的偏见悲伤的刺激。这些结果表明，认知偏差是明显的抑郁症，即使从急性发作恢复后，但没有发现在从来没有抑郁症的哮喘患者。
Previous studies have demonstrated a specific cognitive bias for sad stimuli in currently depressed patients; little is known, however, about whether this bias persists after recovery from the depressive episode. Depression is frequently observed in patients with asthma and is associated with a worse course of the disease. Given these high rates of co-morbidity, we could expect to observe a similar bias towards sad stimuli in patients with asthma. We therefore examined cognitive biases in memory and attention in 20 currently and 20 formerly depressed participants, 20 never-depressed patients diagnosed with asthma, and 20 healthy control participants. All participants completed three cognitive tasks: the self-referential encoding and incidental recall task, the emotion face dot-probe task and the emotional Stroop task. Compared with healthy participants, currently and formerly depressed participants, but not patients with asthma, exhibited specific biases for sad stimuli. These results suggest that cognitive biases are evident in depression even after recovery from an acute episode but are not found in never-depressed patients with asthma.
