The aim of the study was to examine if gaze and emotional expression, both highly self-relevant social signals, affect the recollection accuracy of perceived faces in patients with mesial temporal lobe epilepsy (MTLE).
Forty patients with MTLE (twenty-one without surgery and nineteen after anterior temporal lobectomy) as well as twenty healthy controls (HC) took part in the study. We used a set of 64 facial stimuli: 32 neutral and 32 emotional displays (16 fearful; 16 angry) from well-established affective stimuli databases. Half of the faces in each condition had eyes directed straight and half - away from the observer. Participants performed a gender identification task, and then, after a 45-minute delay were asked to identify the previously seen stimuli, presented among a new set of photos.
Increased automatic learning of angry and fearful compared to neutral expressions was found in HC. There was no emotional enhancement of memory in MTLE but an increased learning for faces with averted than direct gaze.
Our results expand on previous research by demonstrating that emotion expression and gaze direction can affect memory of faces. The study supports the hypothesis that healthy individuals and patients with temporal lobe abnormalities present different patterns of emotional gazes processing. The potential consequences of altered emotional gaze processing and social cognition impairments need to be further investigated to improve the quality of life of patients with MTLE.
本研究旨在探讨注视和情绪表达这两种高度与自我相关的社会信号，是否会影响内侧颞叶癫痫（MTLE）患者对面孔感知的记忆准确性。
40例MTLE患者（21例未接受手术，19例接受前颞叶切除术后）以及20名健康对照者（HC）参与了本研究。我们使用了一组64张面部刺激图片：来自成熟情感刺激数据库的32张中性表情图片和32张情绪表情图片（16张恐惧表情；16张愤怒表情）。每种表情条件下的面部图片中，一半眼睛直视，一半眼睛看向别处。参与者先进行性别识别任务，然后在45分钟延迟后，要求他们从一组新的照片中识别之前看过的刺激图片。
在HC中发现，与中性表情相比，愤怒和恐惧表情的自动学习能力增强。MTLE患者中没有出现记忆的情绪增强现象，但与直视的面部相比，斜视面部的学习能力增强。
我们的研究结果扩展了先前的研究，证明了情绪表达和注视方向会影响对面孔的记忆。该研究支持了以下假设：健康个体和颞叶异常患者呈现出不同的情绪注视加工模式。情绪注视加工改变和社会认知障碍的潜在后果需要进一步研究，以提高MTLE患者的生活质量。
