Your earliest relationships did not just shape your psychology. They shaped your nervous system. This is the neuroscience of how, and what it means.
The psychological patterns that the earlier books in this series described, the hypervigilance of anxious attachment, the suppression of avoidant attachment, the approach-avoidance collapse of disorganized attachment, are not only patterns of thought and behaviour. They are patterns encoded in the brain and body. The nervous system of an insecurely attached adult has been calibrated differently from that of a securely attached one, in documented and measurable ways. Understanding what those differences are, how they arose, and whether and how they can change requires the neuroscience. This is that account.
This is the concluding volume of the Attachment Science Series. It provides the neurobiological foundation for the psychological account developed across the previous five books, written for the reader who wants to understand not only what attachment patterns look like but what they are made of at the level of brain and body.
What this book covers:
- What oxytocin actually does in the research literature, why its role in bonding is substantially more complex than the popular "love hormone" account implies, and why its effects depend critically on attachment history in ways the popular account obscures
- What the HPA axis and cortisol research shows about how early attachment experience calibrates the nervous system's lifelong threat response and what insecure attachment costs the body across time
- What Porges's polyvagal framework and the social engagement system research show about how trauma and insecure attachment affect the nervous system's functional range
- What brain imaging research has revealed about the neural correlates of attachment figures and what the default mode network contributes to mentalizing and reflective functioning
- What Eisenberger and Lieberman's social pain research shows about why rejection and loss activate overlapping neural circuitry with physical pain, and what this means for understanding why attachment threat is felt in the body, not merely in the mind
- What the epigenetics research shows about how early experience modifies gene expression in ways that affect stress reactivity and social behaviour, handled with the precision the popular account rarely provides
- What neuroplasticity actually means in the attachment context, including the honest limits of what the evidence shows about adult neural change
- What the research shows about therapy, sustained responsive relationships, and the neural changes that accompany the movement toward earned security in adulthood
R. V. Langford draws on the research of Eisenberger, Lieberman, Bartz, Feldman, Porges, Meaney, Fonagy, and the developmental neurobiologists who have mapped the consequences of early relational experience on the brain and body, producing the most research-precise account of attachment neuroscience available to the general reader.
Readers who have completed the psychological account this series provides and want the biology beneath it will find it here, presented with the precision and honesty the science deserves.
