Previous research provides evidence that individuals with schizophrenia (SZ) have emotion regulation abnormalities, particularly when attempting to use reappraisal to decrease negative emotion. The current study extended this literature by examining the effectiveness of a different form of emotion regulation, directed attention, which has been shown to be effective at reducing negative emotion in healthy individuals. Participants included outpatients with SZ (n = 28) and healthy controls (CN: n = 25), who viewed unpleasant and neutral images during separate event-related potential and eye-movement tasks. Trials included both passive viewing and directed attention segments. During directed attention, gaze was directed toward highly arousing aspects of an unpleasant image, less arousing aspects of an unpleasant image, or a nonarousing aspect of a neutral image. The late positive potential (LPP) event-related potential component indexed emotion regulation success. Directing attention to nonarousing aspects of unpleasant images decreased the LPP in CN; however, SZ showed similar LPP amplitude when attention was directed toward more or less arousing aspects of unpleasant scenes. Eye tracking indicated that SZ were more likely than CN to attend to arousing portions of unpleasant scenes when attention was directed toward less arousing scene regions. Furthermore, pupilary data suggested that SZ patients failed to engage effortful cognitive processes needed to inhibit the prepotent response of attending to arousing aspects of unpleasant scenes when attention was directed toward nonarousing scene regions. Findings add to the growing literature indicating that individuals with SZ display emotion regulation abnormalities and provide novel evidence that dysfunctional emotion-attention interactions and generalized cognitive control deficits are associated with ineffective use of directed attention strategies to regulate negative emotion.

先前的研究表明,精神分裂症(SZ)患者存在情绪调节异常,尤其是在试图通过重新评价来减少负面情绪时。当前的研究通过检验一种不同形式的情绪调节——定向注意的有效性,扩展了这一文献。定向注意已被证明在减少健康个体的负面情绪方面是有效的。参与者包括SZ门诊患者(n = 28)和健康对照组(CN:n = 25),他们在单独的事件相关电位和眼动任务中观看不愉快和中性的图像。试验包括被动观看和定向注意部分。在定向注意期间,目光被引导至不愉快图像的高唤醒方面、不愉快图像的低唤醒方面或中性图像的非唤醒方面。晚期正电位(LPP)事件相关电位成分指示情绪调节的成功。将注意力导向不愉快图像的非唤醒方面会降低CN组的LPP;然而,当注意力导向不愉快场景的更多或更少唤醒方面时,SZ组的LPP振幅相似。眼动追踪表明,当注意力导向不愉快场景的低唤醒区域时,SZ组比CN组更有可能关注不愉快场景的唤醒部分。此外,瞳孔数据表明,当注意力导向非唤醒场景区域时,SZ患者未能参与抑制关注不愉快场景唤醒方面的优势反应所需的努力认知过程。研究结果进一步丰富了相关文献,表明SZ患者存在情绪调节异常,并提供了新的证据,即功能失调的情绪-注意相互作用和普遍的认知控制缺陷与定向注意策略调节负面情绪的无效使用有关。(PsycINFO数据库记录)
