Internal Working Models of the attachment system modulate emotional responses and the Disorganized attachment pattern is characterized by the breakdown of such regulation. Vagally-mediated heart rate variability (vmHRV) is an index of flexible emotional responding. This study investigated vmHRV in non-clinical adults with an Organized or Disorganized attachment pattern before, during, and after the recall of attachment memories via the Adult Attachment Interview (AAI). Whereas the Organized group exhibited a typical decrease in vmHRV during the AAI and asubsequent return to a baseline-like pattern, the Disorganized group unexpectedly showed a sustained increase in vmHRV during the AAI which also persisted during the recovery phase. Results suggest that while Organized face the recollection of attachment memories by showing the adaptive stress response characterized by parasympathetic withdrawal and immediate recovery, individuals with Disorganized attachment need to keep regulating their emotions effortfully both during and after the recall of potential traumatic events.
依恋系统的内部工作模式调节情绪反应，而依恋关系紊乱的特征是这种调节的崩溃。迷走神经介导的心率变异性（vmHRV）是灵活情绪反应的一个指标。本研究通过成人依恋访谈（AAI）调查了具有组织或紊乱依恋模式的非临床成年人在回忆依恋记忆前后的 vmHRV。虽然组织组在 AAI 期间表现出典型的 vmHRV 降低，随后恢复到基线样模式，但紊乱组出人意料地在 AAI 期间持续增加 vmHRV，在恢复阶段也持续增加。结果表明，虽然组织组通过表现出以副交感神经撤退和即时恢复为特征的适应性应激反应来面对依恋记忆的回忆，但具有紊乱依恋关系的个体在回忆潜在创伤事件期间和之后都需要努力调节自己的情绪。
