Aim of the present study was to investigate the time course of brain processes involved in the visual perception of different gaze interactions in woman-child dyads and the association between attachment dimensions and brain activation during the presentation of gaze interactions. The hypothesis was that the woman avoidance will produce a greater activation of primary somatosensory and limbic areas. The attachment styles dimensions avoidant-related will be associated with fronto-limbic brain intensity during the convergence of gaze. Electroencephalogram (EEG) data were recorded using a 256-channel HydroCel Geodesic Sensor Net in 44 female subjects (age: 24 ± 2 years). Event-related potential (ERP) components and standardized low-resolution electromagnetic tomography (sLORETA) were analyzed. Participants were administered the attachment style questionnaire before EEG task. A lower P350 latency was found in the fronto-central montage in response to woman avoidance. sLORETA analysis showed a greater intensity of limbic and primary somatosensory areas in response to woman avoidance compared to the others gaze interactions. In response to convergence gaze, the confidence attachment dimension was negatively correlated with the intensities of the right temporal and limbic areas, and the relationships as secondary attachment dimension were positively correlated with the intensities of the bilateral frontal areas and of the left parietal area.
本研究的目的是调查母婴二元组中不同注视互动视觉感知所涉及的大脑过程的时间进程，以及注视互动呈现过程中依恋维度与大脑激活之间的关联。假设是女性的回避行为会使初级体感区和边缘区产生更大的激活。与回避相关的依恋风格维度将与注视汇聚期间的额边缘脑强度相关。使用256通道HydroCel Geodesic传感器网络记录了44名女性受试者（年龄：24±2岁）的脑电图（EEG）数据。分析了事件相关电位（ERP）成分和标准化低分辨率电磁断层扫描（sLORETA）。在进行脑电图任务之前，对参与者进行了依恋风格问卷调查。在额中央导联中，对女性回避行为的反应发现P350潜伏期较短。sLORETA分析显示，与其他注视互动相比，对女性回避行为的反应中，边缘区和初级体感区的强度更大。在对汇聚注视的反应中，自信依恋维度与右侧颞叶和边缘区的强度呈负相关，而作为次要依恋维度的关系与双侧额叶和左侧顶叶区域的强度呈正相关。
