Objective： To investigate the emotional conflict in patients with major depressive disorder （MDD） by an affective priming paradigm. Methods： 20 depressed patients and 18 matched normal controls were measured. The prime stimuli were positive, negative or depression-related words, and the target stimuli were positive or negative faces. The subjects were asked to judge whether the target expressions were positive or negative. Results： The general emotional conflict effects induced by the negative words were found in both depressed patients and controls. When the target faces were positively valenced, the emotional conflict effects induced by the depression-related words were significantly greater than that induced by the negative words in depressed patients, while such difference did not occur in normal controls. Furthermore, the regression analysis identified a significant linear relationship between the depression-related emotional conflict effects and the BDI scores. Conclusion： The abnormal emotional conflict in depressed patients may be due to the attentional bias to the depression-related information.
