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
Lifespan Integration
Core mechanism: Proposed: repeated chronological review of life memories gives the nervous system evidence that the danger is over and belongs to the past, shifting implicit body-level expectations about safety and self. The repetition, rather than the content of any single memory, is held to be the active ingredient. This is a clinical hypothesis. It has not been tested against a credible control, and LI's own literature does not settle what the timeline is doing.
Ontology: Fragmented temporal integration: the self is stuck in past time, experiencing old threat as present. The body has not updated its felt sense of when it is.

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; clients without developmental trauma are a fit question rather than a contraindication, since standard EMDR will usually do the job with less scaffolding
Therapeutic voice: Let's bring in your nurturing figure. Can you feel their presence with you? Stay with that, and follow the taps.
Lifespan Integration
Philosophical roots: Siegel (interpersonal neurobiology: neural integration across time); van der Kolk (the body keeps the score: implicit memory); Schore (affect regulation and repair of early attachment); Bowlby (internal working models); Janet (dissociation as temporal fragmentation)
Blind spots: Limited controlled research base; mechanism of action not well understood neuroscientifically; can be over-applied to presentations that need more stabilization first; rapid pace of timeline repetitions may overwhelm some dissociative clients
Therapeutic voice: We're going to go through the timeline again. You don't have to say anything or make sense of it. Just notice each cue and let the next one come. If it starts to feel repetitive or like nothing much is happening, that's fine, keep going.
Choosing between them
Attachment-Focused EMDR and Lifespan Integration both sit within the Trauma-Focused tradition — they share a worldview about what suffering is and how change happens. Differences are more often about technique and emphasis than about underlying theory.
