依恋的神经生理机制

在动物社会依恋的神经生物学研究基础上，研究者对人类依恋的神经生理机制进行了初步探讨，一致的结论是无论婴儿还是成人，不安全依恋个体的心率、皮质醇水平高于安全依恋的个体。而在依恋系统激活时婴儿和成人的脑电活动和大脑的功能定位研究却发现了不一致：较之安全依恋婴儿，不安全依恋婴儿的左侧前额大脑区域显示了较少的活动；成人依恋类型的脑机制研究并无定论。所有这些研究多为相关研究，今后有待于在神经生物水平上对依恋的基本理论问题如内部工作模式的意识和无意识性、母婴依恋与成人依恋的关系（特别是一般依恋表征和特殊依恋表征）以及母婴依恋对婴幼儿大脑发育的影响等问题展开深入研究

Neurophysiological Mechanism of Human Attachment

Attachment researchers investigated the neurophysiological mechanism of human attachment based on neurobiology studies of animal social attachment. They made a conclusion that the insecure individuals have higher heart rate and high cortisol comparing with the secure ones , While the location of brain function and electrophysiological study shows that compared to secure infants, insecure infants exhibited less left frontal brain activities when attachment system was inactivated, but there are no consistent results in adults. However, the researches are mostly correlational ones and can not provide causal inferences, moreover, the further researches about basic physiological characteristic of attachment need to be reinforced and discovered
