How they work
Attachment-Focused EMDR
Core mechanism: Bilateral stimulation within an attuned relational context activates the attachment system while processing early wounds, enabling internalization of a secure base through both the therapeutic relationship and imaginal resource figures
Ontology: The self as shaped by early relational deficits — not primarily by discrete traumatic events but by chronic failures of attunement — that require both trauma processing and relational repair
Circle of Security
Core mechanism: Helping caregivers recognize and regulate their own triggered defensive responses (shark music) so they can remain present to their child's actual attachment needs on the Circle of Security — providing safe haven when the child needs comfort and secure base when the child needs to explore
Ontology: Child security develops through repeated experience of a caregiver who is bigger, stronger, wiser, and kind — present enough to provide safe haven and secure base, and capable of reflecting on their own triggered responses without being controlled by them.

What each assumes — and misses
Attachment-Focused EMDR
Philosophical roots: Bowlby (attachment theory); Ainsworth (secure base); Main (disorganized attachment); Winnicott (good enough mother); Siegel (interpersonal neurobiology)
Blind spots: Limited independent research base; departure from standard EMDR fidelity raises questions for purists; requires both EMDR and attachment theory competence; some modifications not empirically validated independently
Therapeutic voice: Let's bring in your nurturing figure. Can you feel their presence with you? Stay with that, and follow the taps.
Circle of Security
Philosophical roots: Bowlby (attachment theory, safe haven and secure base); Ainsworth (Strange Situation, attachment patterns); Main (Adult Attachment Interview, reflective function); Winnicott (good enough mothering); Stern (attunement, intersubjectivity)
Blind spots: COS-P group protocol relies on DVD-based delivery which limits individualization; home visiting version requires significant training and supervision; not appropriate for active child abuse situations without additional safety planning; caregiver's own attachment trauma may require individual therapy beyond what COS provides
Therapeutic voice: When your child reached for you just then and you pulled back — what were you feeling in that moment? Not what you thought. What you felt.
Choosing between them
Attachment-Focused EMDR (Trauma-Focused) and Circle of Security (Family Systems) come from different traditions, which means they assume different things about what a person is, what causes suffering, and what the therapeutic relationship is for. The choice between them is often less about "which works better" and more about which set of assumptions fits the client and the therapist.
