Early life experiences, including attachment-related experiences, inform internal working models that guide adult relationship behaviors. Few studies have examined the association between adolescent attachment and adult relationship behavior on a neural level. The current study examined attachment in adolescence and its associations with neural correlates of relationship behaviors in adulthood.
85 participants completed the Adult Attachment Interview (AAI) at age 14. Ten years later, at age 24, participants underwent functional brain image when participants were under the threat of electric shock alone, holding the hand of a stranger, or their partner.
We found that adolescents who were securely attached at age 14 showed increased activation in regions commonly associated with cognitive, affective, and reward processing when they held the hand of their partner and stranger compared to being alone. Adolescents with higher preoccupied attachment scores showed decreased activation in similar regions only during the stranger handholding condition compared to being alone.
These findings suggest that adolescent attachment predicts adult social relationship behaviors on a neural level, in regions largely consistent with previous literature. Broadly, this study has implications for understanding long-term links between attachment and adult relationship behaviors and has potential for informing intervention.
早期生活经历,包括与依恋相关的经历,塑造了指导成人关系行为的内部工作模式。很少有研究在神经层面上考察青少年依恋与成人关系行为之间的关联。本研究考察了青少年期的依恋及其与成年期关系行为的神经关联。
85名参与者在14岁时完成了成人依恋访谈(AAI)。十年后,在24岁时,参与者在单独面对电击威胁、握住陌生人的手或其伴侣的手时接受了功能性脑成像。
我们发现,14岁时安全型依恋的青少年,与独自面对电击威胁相比,在握住伴侣和陌生人的手时,通常与认知、情感和奖赏加工相关的脑区激活增加。与独自面对电击威胁相比,在握住陌生人的手的情况下,先占型依恋得分较高的青少年在类似脑区的激活减少。
这些发现表明,青少年期的依恋在神经层面上预测了成人的社会关系行为,涉及的脑区在很大程度上与先前文献一致。总体而言,本研究对于理解依恋与成人关系行为之间的长期联系具有启示意义,并具有为干预提供信息的潜力。
