Ecker and Hulley began developing experiential methods to intentionally facilitate this process. They found that a majority of their clients could begin having experiences of the underlying coherence of their symptoms from the first session. In addition to creating a methodology for swift retrieval of the emotional schemas driving symptom production, they also identified the process by which retrieved schemas then undergo profound change or dissolution: the retrieved emotional schema must be activated while concurrently the individual vividly experiences something that sharply contradicts it. Neuroscientists subsequently determined that these same steps are precisely what unlocks and deletes the neural circuit in implicit memory that stores an emotional learning—the process of reconsolidation.
