What the float-back and affect bridge are
The float-back (Browning, 1999) and the affect bridge (Watkins, 1971) are two complementary EMDR Phase 1 techniques for finding the touchstone memory — the earliest accessible experience that carries the same negative cognition, emotion and body signature as a client's present-day disturbance. The two techniques solve the same problem from different angles. The float-back starts from a clear negative cognition ("I'm not safe", "I'm not good enough") and asks the client's mind to drift back along the belief. The affect bridge starts from a clear emotion or body sensation and asks the client to drift back along the felt sense.
Both end at the same place: an earlier memory with matching NC, emotion and body signature. That earlier memory becomes the touchstone — the first target in the Target Sequence Plan, and usually the first memory reprocessed in Phase 4.
Why finding the touchstone matters
Standard EMDR depends on the principle of generalisation: reprocessing the earliest memory in a network tends to collapse the disturbance across linked later memories. Starting reprocessing on the most distressing or most recent memory often produces slower, less complete results because the network's earliest node is left untouched. Shapiro (2018) describes this as the difference between cutting a vine at its root versus cutting it at the leaves.
The touchstone is not always the worst memory and not always the most recent — it is the earliest memory the client can access that carries the same NC cluster as the present disturbance. The float-back and affect bridge are the two reliable techniques for locating it.
When to use the float-back vs the affect bridge
Use the float-back when the client can articulate a clear negative cognition ("I'm worthless", "I'm in danger", "It was my fault"). The verbal anchor of the NC gives the mind something concrete to follow back.
Use the affect bridge when the emotion or body sensation is vivid but the cognition is hard to put into words — common with somatic presentations, preverbal trauma, dissociated material, or clients who present "I just feel awful and I don't know why." The body holds the thread even when language can't.
Most clinicians try the float-back first and switch to the affect bridge if it doesn't surface a memory. Both can be re-attempted across multiple Phase 1 sessions — the touchstone sometimes surfaces only once the client has done some preparation work and feels safer dropping into the body.
How to use the worksheet in session
1. Identify the present-day disturbance — a recent trigger, a relationship pattern, a panic episode. Fill in the header section with the client's own words.
2. Activate the disturbance: ask the client to bring up the image, the NC, the emotion, the body location, and a SUD. The worksheet has dedicated fill-ins for each. Don't rush this — the more vivid the present activation, the more reliably the past memory will surface.
3. Run the float-back script (suggested wording on page 2) if the NC is clear. Run the affect-bridge script if the emotion or body sensation is clear. Both are short — 30–60 seconds of held attention is usually enough.
4. Capture whatever memories arise in the somatic map grid (memory, approximate age, SUD, NC match). The earliest memory with the same NC and body signature is your touchstone candidate.
5. Run the readiness checklist before booking the first Phase 3 session — Calm Place, Container, dissociation screen, stop signal, between-session plan. The Resourcing Scripts PDF covers what needs to be in place first.

When no earlier memory surfaces
Two clean float-back attempts that produce no earlier memory is meaningful clinical data, not a failure. Three possibilities, in this order:
1. The present incident is the touchstone. Adult-onset single-incident trauma (a car accident, an assault, a medical procedure) sometimes has no earlier antecedent in the network. Move forward with standard Phase 3 on the present scene and reprocess as the first target.
2. The earlier memory is dissociated or implicit. Clients with preverbal, dissociated, or heavily defended trauma may not be able to access the earlier memory consciously yet. Add more Phase 2 preparation — install Calm Place and Container, screen formally for dissociation with the DES-II if you haven't, and revisit the float-back in a later session.
3. The cognition isn't quite right. Try a different negative cognition from the same cluster (e.g. shift from "I'm not safe" to "I'm helpless"). A small shift in the NC sometimes unlocks the earlier memory the original NC couldn't reach. The Negative Cognition Cluster handout lists the standard alternatives by cluster.

Frequently asked questions
What's the difference between float-back and affect bridge?
Float-back starts from a clear negative cognition; affect bridge starts from a clear emotion or body sensation. Both lead to the same place — the earliest accessible memory with matching NC, emotion, and body signature.
When in Phase 1 should I use this?
Usually in session 2 or 3 of Phase 1, after intake and the dissociation screen, once the client is regulated enough to drop into the body for 30–60 seconds. Some clinicians also use it at the start of Phase 3 if a newly-identified target seems to have no clear 'first time'.
What if the client can't drop into the body?
Do more Phase 2 preparation first. The float-back and affect bridge both require the client to hold an activated state for 30–60 seconds. If that's not yet tolerable, the touchstone search is premature.
Is this the same as 'going back in time'?
No — neither technique uses age regression or hypnosis. The client stays oriented to the present; we're simply asking the associative memory network to surface a linked earlier experience.
