Assigiolia’s subpersonalities, Watkins and Watkins ego state approach and Schwartz’s internal family systems models are only a few of them. Working with the ”inner child” is now common. While all of these have value, ETT® has produced an internal parts model that operates at an entirely new level. This PES model possess some of the following attributes:

• There may be any number of internal parts that varies with each individual and their function may vary from previous parts models.

• Access to each internal part can take place by literally turning a dial which causes internal parts to emerge within seconds as separate entities.

• A therapist can isolate a specific internal part to work with one at a time.

• Many internal parts are implicit and may not be accessible through conscious verbal dialogue but can be readily accessed by the PES technique.

• PES can access specific somatic symptoms found in each internal part and often relieve it within minutes.

• PES is particularly valuable for quickly reducing emotional overwhelm.

• Each inner part may possess separate configurations of cognitive, affective, behavioral, somatic and perspectives.

• By being able to instantly access distinct inner psychological parts, a procedure to resolve inner conflicts rapidly can be used.

• Hidden positive inner resources can be accessed readily and can be used to resolve emotions and issues within minutes.

• New insights frequently occur within minutes.

• These attributes do not exist in any other forms of internal parts models as quickly and efficiently.

• PES often accesses parts of internal psychological parts with great precision.
