非临床抑郁个体内隐心境一致性记忆的意识加工和无意识加工的差异：一项ERP研究

以情绪面孔为刺激材料，采用改进的内隐知觉记忆测验任务，考察非临床抑郁个体在内隐心境一致性记忆的意识加工和无意识加工差异。结果发现：在150ms—200ms时间窗内隐记忆的无意识和意识加工过程存在重叠现象。在250ms—350ms时间窗个体就表现出了意识加工过程和无意识加工过程的分离现象，并且非临床抑郁组的无意识加工过程存在负性心境一致性记忆偏向。在400ms-800ms时间窗内，两组被试均表现出无意识加工过程中存在负性心境一致性记忆偏向。表明在250ms-350ms，非临床抑郁个体内隐记忆的无意识加工过程存在缺陷，表现出负性心境一致性记忆偏向。

Implicit mood-congruent memory with and without awareness in dysphoria: An event-related potentials study

To discriminate the ERP difference of the awareness and unawareness processing of mood-congruent memory, event-related potentials (ERPs) were used while subjects completed the improved implicit mood-congruent memory test. The results indicated the overlap of awareness and unawareness processing in the time-windows (150ms-200ms), the separation of awareness and unawareness processing and negative mood-congruent memory bias in the unawareness processing of the dysphoric subjects in the time-windows (250ms-350ms), and the negative mood-congruent memory bias in the unawareness processing of two groups in the late time-windows(400ms-800ms). Altogether, these results explore the weakness of unawareness processing in implicit memory and the negative mood-congruent memory bias in dysphoria during the time-windows (250ms-350ms).
