Attachment styles as coupling patterns

Attachment theory (Bowlby, Ainsworth, Mikulincer & Shaver) describes stable priors for how a mammal regulates arousal in close coupling. In FPE terms, attachment is not a separate module — it is learned defaults for \(\Phi\), \(\mathcal{D}_{KL}\), \(\Gamma\), and \(P_{in}\eta\) in dyads that function as co-regulatory substrate.

Secure base ≈ high \(\Phi\), low \(\Gamma\)

A secure attachment figure provides:

Secure adults approximate fractal coherence: relational \(\Phi\) supports cellular \(\Phi\) (sleep, HPA tone, immune function — Porges, McEwen).

Insecure patterns as term skews

Style Folk label Numerator Denominator Fractal
Anxious Protest, cling \(P_{in}\) mobilised but low \(\eta\) (protest, pursuit) High \(\mathcal{D}_{KL}\) (“abandonment imminent”) \(\Phi\) feels fragile → hyper-monitor partner
Avoidant Withdrawal Suppressed phasic \(P_{in}\); tonic may look “fine” Self-\(\mathcal{D}_{KL}\) (needs minimised in model) \(\Gamma\) avoided by distance; \(\Phi\) not co-regulated
Disorganised Approach–avoid Conflicting \(P_{in}\) commands Model incoherent → high \(\mathcal{D}_{KL}\) Often trauma: \(\Psi\) or caregiver \(\Phi\) was threat

Anxious attachment

Avoidant attachment

Disorganised attachment

Internal working models = priors on \(Q\)

Bowlby’s internal working model is the attachment prior on generative models of self and other:

Therapy that updates attachment is, operationally, Bayesian model revision on those priors — lowering \(\mathcal{D}_{KL}\) about what closeness costs.

Pairings (common traps)

Dyad Attractor
Anxious–avoidant Pursuer raises \(\Gamma\); withdrawer raises \(\mathcal{D}_{KL}\) by silence → classic friction cycle
Anxious–anxious Escalation arms race; both pay high \(P_{in}\), low \(\eta\)
Avoidant–avoidant Low \(\Gamma\) surface, high latent \(\mathcal{D}_{KL}\); rupture on crisis

Interruption

  1. Restore \(\Phi\): sleep, safety, somatic regulation before “relationship skills.”
  2. Raise \(\eta\) on \(P_{in}\): observable + consequence, not protest script.
  3. Lower \(\mathcal{D}_{KL}\): name needs and fears as hypotheses, test against behaviour.
  4. Lower \(\Gamma\): repair rituals; if repair impossible, exit may be the \(\Gamma\)-optimal move.
