成人依恋风格在信息加工中表现出差异性的神经机制

依恋风格的神经机制研究有助于更深层次理解依恋行为与类型：N1、N200、N400和P300等脑电成份的差异反映了不同依恋风格在编码、提取及注意资源分配上的不同; 额叶皮层、扣带回皮层、颞极、杏仁核、海马等脑区可以反映不同依恋风格在信息加工性质和注意资源分配上的差异。已有研究除安全依恋和非安全依恋策略的有效性在脑成像上的研究与依恋理论一致外, 其余研究还存在争议。未来的研究可深入探究更高质量的依恋测量工具, 依恋风格对内隐刺激加工影响的认知神经机制; 细化依恋风格在信息加工不同阶段的神经活动和脑成像研究; 以及关注依恋风格对信息加工影响差异的脑机制在临床治疗中的运用。

The Neural Mechanism of Adult Attachment Styles’ Differences in the Information Processing

The research of the neural mechanism of adult attachment style contributes to a the deeper understanding of attachment behaviors and attachment types: The differences in N1, N200, N400 and P300 reflect that people with different attachment styles may differ in encoding, retrieving, and the allocation of attentional resources. The activities of brain areas, such as frontal cortex, cingulate cortex, temporal pole, amygdala, and hippocampus, might reflect the fact that people with different attachment styles have different cognitive mechanisms and ways to allocate attentional resources in the information processing. So far there is only a consistency between fMRI studies and the attachment theories on the effectiveness of secure and insecure attachment strategies, and studies other than that are still in dispute. Future researches can focus on developing higher quality questionnaires to measure adult attachment styles, exploring the neural mechanism of the processing of implicit stimulus affected by attachment styles, and refining how attachment styles influence the neural activities and brain images of different stages of the information processing, and examining the application of attachment styles’ impact on brain mechanisms of information processing in clinical treatment.
