Abstract

This study investigated implicit socioemotional modulation of working memory (WM) in the context of symptom severity and functional status in individuals with psychosis (N = 21). A delayed match-to-sample task was modified wherein task-irrelevant facial distracters were presented early and briefly during the rehearsal of pseudoword memoranda that varied incrementally in load size (1, 2, or 3 syllables). Facial distracters displayed happy, sad, or emotionally neutral expressions. Implicit socioemotional modulation of WM was indexed by subtracting task accuracy on nonfacial geometrical distraction trials from facial distraction trials. Results indicated that the amount of implicit socioemotional modulation of high WM load accuracy was significantly associated with negative symptoms (r = 0.63, P < 0.01), role functioning (r = -0.50, P < 0.05), social functioning (r = -0.55, P < 0.01), and global assessment of functioning (r = -0.53, P < 0.05). Specifically, greater attentional distraction of high WM load was associated with less severe symptoms and functional impairment. This study demonstrates the importance of the WM-socioemotional interface in influencing clinical and psychosocial functional status in psychosis.

并非所有的分心都是不好的:工作记忆容易受到内隐社会情绪分心的影响,与精神病的负面症状和功能损害有关。
本研究探讨了内隐社会情绪在精神病患者症状严重程度和功能状态下对工作记忆(WM)的调节作用。对延迟匹配样本任务进行了改进,其中任务无关的面部干扰物在假单词记忆的排练中被提前和短暂地呈现,这些假单词记忆的负载大小逐渐变化(1、2或3个音节)。面部干扰显示出快乐、悲伤或情绪中性的表情。内隐社会情绪调节是通过从面部分心试验中减去非面部几何分心试验的任务准确性来索引的。结果显示,高WM负荷准确性的内隐社会情绪调节量与负面症状(r = 0.63, P < 0.01)、角色功能(r = -0.50, P < 0.05)、社会功能(r = -0.55, P < 0.01)和整体功能评估(r = -0.53, P < 0.05)显著相关。具体而言,高WM负荷的注意力分散程度越大,症状和功能损害程度越轻。本研究证明了精神障碍与社会情绪界面在影响精神病患者临床和社会心理功能状态方面的重要性。
