Differences in adult attachment may concord with differences in social perception. The present study aimed to measure neural activity associated with the presentation of visual social stimuli. In an affective oddball paradigm, event-related brain potentials were recorded while participants viewed negative, positive, and neutral images of people and categorized them according to valence. Brain response amplitudes were examined across valence categories and across attachment groups. Results revealed differences between anxious and avoidant groups in "emotion bias." The avoidant group displayed a bias towards more neural activation in response to negative compared to positive images. The anxious group trended in the opposite direction. Results are discussed in terms of possible attachment-based differences in motivated attention to social stimuli.
成人依恋的差异可能与社会认知的差异相一致。本研究旨在测量与视觉社会刺激呈现相关的神经活动。在一个情感奇偶数范式中，当参与者观看人物的负面、正面和中性图像并根据效价对其进行分类时，记录了事件相关脑电位。研究考察了不同效价类别和不同依恋组之间的脑反应幅度。结果显示，焦虑组和回避组在“情绪偏差”方面存在差异。与正面图像相比，回避组在面对负面图像时表现出更强的神经激活倾向。焦虑组则呈现相反的趋势。研究结果从基于依恋的对社会刺激的动机性注意可能存在的差异方面进行了讨论。
