Abstract：
UNASSIGNED: Individuals with anxiety disorders (ADs) often display hypervigilance to threat information, although this response may be less pronounced following psychotherapy. This study aims to investigate the unconscious recognition performance of facial expressions in patients with panic disorder (PD) post-treatment, shedding light on alterations in their emotional processing biases.
UNASSIGNED: Patients with PD (n=34) after (exposure-based) cognitive behavior therapy and healthy controls (n=43) performed a subliminal affective recognition task. Emotional facial expressions (fearful, happy, or mirrored) were displayed for 33 ms and backwardly masked by a neutral face. Participants completed a forced choice task to discriminate the briefly presented facial stimulus and an uncovered condition where only the neutral mask was shown. We conducted a secondary analysis to compare groups based on their four possible response types under the four stimulus conditions and examined the correlation of the false alarm rate for fear responses to non-fearful (happy, mirrored, and uncovered) stimuli with clinical anxiety symptoms.
UNASSIGNED: The patient group showed a unique selection pattern in response to happy expressions, with significantly more correct \"happy\" responses compared to controls. Additionally, lower severity of anxiety symptoms after psychotherapy was associated with a decreased false fear response rate with non-threat presentations.
UNASSIGNED: These data suggest that patients with PD exhibited a \"happy-face recognition advantage\" after psychotherapy. Less symptoms after treatment were related to a reduced fear bias. Thus, a differential facial emotion detection task could be a suitable tool to monitor response patterns and biases in individuals with ADs in the context of psychotherapy.

摘要：
■患有焦虑症（AD）的人经常对威胁信息表现出高度警惕，尽管这种反应在心理治疗后可能不太明显。本研究旨在探讨惊恐障碍(PD)患者治疗后面部表情的无意识识别表现,揭示他们情绪处理偏见的变化。
■经过（基于暴露的）认知行为治疗和健康对照（n=43）的PD患者（n=34）执行了潜意识情感识别任务。情感面部表情（恐惧，快乐,或镜像）显示33ms，并由中性面向后掩盖。参与者完成了一项强制选择任务，以区分短暂呈现的面部刺激和仅显示中性面具的未发现状况。我们进行了二次分析，以根据四种刺激条件下的四种可能的反应类型对群体进行比较，并检查了恐惧反应的误报率与非恐惧（快乐，镜像，并发现）具有临床焦虑症状的刺激。
■患者组对快乐表情表现出独特的选择模式，与对照组相比，“快乐”的反应明显更正确。此外,心理治疗后焦虑症状严重程度降低与无威胁表现的虚假恐惧反应率降低相关.
■这些数据表明，PD患者在接受心理治疗后表现出“快乐人脸识别优势”。治疗后症状减少与恐惧偏见减少有关。因此，在心理治疗的背景下,不同的面部情绪检测任务可能是监测AD患者反应模式和偏见的合适工具.
