Most studies show that self-processing in schizophrenia is impaired at the supraliminal level. Schizophrenic patients generally lack the ability to prioritize the processing of self-related information, such as their own face. However, some evidence suggests that schizophrenic patients may retain intact subliminal processing abilities even though their conscious experiences are compromised. We conducted the first study exploring schizophrenic patients' subliminal self-face processing. Using a breaking continuous flash suppression (bCFS) paradigm, we interocularly suppressed face images (self, famous, and unknown faces). Participants' reaction times to detect the faces when they broke the suppression were recorded as an index for the subliminal processing of faces. Unlike the healthy controls, schizophrenic patients did not demonstrate a processing advantage for their own face when it broke interocular suppression; only a face familiarity effect was found. These findings contribute to the understanding of self-processing deficits in schizophrenia.
大多数研究表明，精神分裂症患者的超敏自我加工受损。精神分裂症患者通常缺乏优先处理自我相关信息（如自己的脸）的能力。然而，一些证据表明，精神分裂症患者即使意识体验受损，也可能保持完整的潜意识处理能力。我们进行了第一项研究，探索精神分裂症患者的潜意识自我面孔处理。使用打破连续闪光抑制（bCFS）范式，我们在眼间抑制面孔图像（自我、著名和未知面孔）。当抑制被打破时，参与者检测面孔的反应时间被记录为面孔潜意识处理的指标。与健康对照组不同，精神分裂症患者在自己的面孔打破眼间抑制时没有表现出对自己面孔的处理优势；仅发现了面孔熟悉度效应。这些发现有助于理解精神分裂症中的自我处理缺陷。
