The Adaptive Information Processing Model
The AIP model is EMDR's theoretical foundation. It explains how memories are stored, why some become 'stuck', and how bilateral stimulation supports processing.

Overview
The Adaptive Information Processing (AIP) model is the theoretical framework Francine Shapiro developed to explain EMDR. Its central claim is that the brain has an innate information-processing system that normally integrates experiences into adaptive memory networks, and that trauma occurs when this system is overwhelmed and a memory is stored in a dysfunctional, insufficiently processed form.
What the evidence says
The AIP model is a clinical theory rather than a fully specified neuroscientific mechanism, but it is consistent with contemporary memory-reconsolidation research and provides a coherent conceptual map for EMDR's eight-phase protocol.
In practice
Clinically, the AIP model implies that presenting symptoms are frequently rooted in earlier unprocessed experiences. Case conceptualization in EMDR therefore includes identifying past adverse events (touchstone memories), present triggers and future templates, and processing them in a way that lets the innate system finish what it started. Bilateral stimulation is the procedural element used to facilitate that processing.
Frequently asked questions
- Is AIP a proven neurological mechanism?
- AIP is a clinical model that guides EMDR practice. Its specific neural mechanisms are still being investigated; it is consistent with reconsolidation-based accounts of memory change.
