Schore: Attachment Neurobiology of Co-Regulation (UCLA, allanschore.com)

The brain develops self-regulation through thousands of co-regulated moments

Allan Schore's decades of work argue the right brain develops largely through dyadic relationship with the primary caregiver in the first two years. Co-regulation is the mechanism. When the loop is repeatedly broken, the brain wires for distress and dissociation rather than regulation.

Allan Schore is a neuropsychologist whose decades of work on attachment neurobiology argue that the right brain develops largely through the dyadic relationship with the primary caregiver in the first two years of life. The mechanism, in his account, is moment-to-moment co-regulation: the infant cries, the caregiver responds, the infant's arousal regulates, the caregiver mirrors the regulated state, and over thousands of repetitions, the infant's brain develops the architecture for self-regulation.

When that loop is repeatedly broken, as it is by extinction sleep training, the developing brain has to make do with the alternative. The alternative, in Schore's framework, is a developmental pattern where the right brain wires for distress and dissociation rather than regulation. The framework draws on neuroimaging, animal studies of separation, and clinical data on adult patients with regulation disorders.

Why it matters

If the brain develops its regulation systems through specific repeated experiences with the caregiver, then interrupting those experiences during the critical period is not a neutral choice. It is a developmental input the brain has to work around.
