【摘要】：本研究拟采用点探测范式及不同情绪内容的面孔刺激(高兴、中性、悲伤和愤怒)考察阈下抑郁个体的负性注意偏向及其内在机制。点探测任务中情绪面孔配对呈现(负性-中性、正性-中性),配对面孔中的情绪线索位置与靶刺激的位置构成负性一致/不一致和正性一致/不一致条件,同时实验中加入"中性-中性"面孔线索作为一致和不一致条件的对比基线来考察注意偏向的内在机制。结果发现,阈下抑郁个体在负性不一致条件下的反应时显著长于负性一致条件,表明阈下抑郁个体具有对负性刺激的注意偏向;进一步比较发现,阈下抑郁个体在负性不一致条件下的反应时显著的长于"中性-中性"基线条件,而负性一致条件与基线之间差异不显著,表明阈下抑郁个体的负性注意偏向为对负性刺激的注意解脱困难。结果另发现,阈下抑郁个体未能像无抑郁对照组个体表现出对正性刺激的注意偏向。结果表明,处于阈下抑郁状态的个体表现出对负性刺激的注意偏向,具体为对负性刺激的注意解脱困难,其原因可能是由于阈下抑郁个体在注意控制和情绪调节功能上的紊乱。
[Abstract]:The present study intends to investigate the negative attention bias and its intrinsic mechanism of subthreshold depression individuals using point detection paradigm and facial stimuli (happiness, neutrality, sadness and anger) with different emotional content. In the spot detection task, the emotional faces were paired (negative-neutral, positive-neutral). The location of emotional cues in the paired faces constituted negative consistency / inconsistency and positive consistency / inconsistency with the position of the target stimulus. At the same time, the neutral-neutral facial cues were added as the comparative baseline of the consistent and inconsistent conditions to investigate the intrinsic mechanism of attention bias. The results showed that the response time of subthreshold depression individuals was significantly longer than that of negative consistent conditions, indicating that subthreshold depression individuals had an attentional bias towards negative stimuli. The response time of subthreshold depression individuals under negative inconsistent conditions was significantly longer than that of "neutral" baseline conditions, but there was no significant difference between negative consistent conditions and baseline conditions. The results showed that the negative attention bias of subthreshold depression individuals was difficult to relieve the attention of negative stimuli. It was also found that subliminal depression did not show a bias towards positive stimuli as that in the control group. The results showed that individuals in the state of subthreshold depression showed attention bias to negative stimuli, which was mainly due to the disorder of attention control and emotion regulation in individuals with subthreshold depression.
