Some of the capacities are approach oriented and some are retreat oriented. If the first group are active, and then the second become powerfully activated by some awful event, we might get what might be called a split. BUT, this would require that part of what was originally one ego-state/alter [Note here: He is talking about formed ego states and alters rather than an infants behavorial states] either now goes with the split part, or remains accessible to the split part, in the same way that all alters which can talk (and I'm convinced that we cannot assume that all can, at least not initially) have access to the how-to-talk parts of the brain.
Certainly, some people will conceptualize this as splitting. But of what? I don't think we really know, but here are two ways I could see this happening:
1. Given that we enter the world with basic neurological responses which, at the most basic level, are about either approach, or retreat, as time passes these basic responses get connected to various memories, and groups of memories. Initially, these are just BEHAVIORAL STATES, for example: me-who-eats / me-who-sleeps / me-who-snuggles-with-Mommy / etc. They are turned on and off in response to cuing or triggering stimuli, external or internal.
Here I might say that it seems correct to think of the brain as a self-programming organic computer, whose task is to navigate the environment so as to sustain itself. It learns the structure of its environment (both physical and social), over time, and thus increasingly is able to respond to internally derived needs and impulses (desires, etc.) on its own, without external assistance.
These organic programs are initially just sets of environmental "maps" with associated responses. A simple example: I may learn that mommy is often in the kitchen, AND that she is a food source, so when I'm hungry, I'll crawl into the kitchen and get fed. Problem solved! But what if mommy is a drunk, and gets abusive at times, when I approach her? Or just passes out, so that she is only responsive to me some of the time? Problem NOT solved!
This complication may well be beyond my ability to resolve, and so I begin to get chronically anxious, in relation to my frequent surges of hunger. Hunger can lead to food, the experience of abandonment, or being slapped. I cannot predict. Add to this additional complications, all involving distressing levels of distressing feeling, and my little brain will become so overwhelmed it can barely function. THIS will seriously interfere with the natural process of integrating my hunger-response-program with my I-want-a-cuddle-response-program and my I-want-to-play-program. They may not integrate as all. As my sense of self grows over time, it will grow in these separate areas of my brain, as separate identities. [Note: This is not splitting. It is a lack of integration]
There can also come to be a me-who-got-attacked by that big dog. This might be developed from me-who-plays-outdoors (during which at one time I got attacked). The play-outdoors is basically an elaborated (programmed) approach system, but the attack stimulates a retreat response. The question is whether or not the two can be brought together. That there is an INITIAL "split" is true because consciousness is a small place. [Now it gets complicated!]
The emotions associated with the attack WILL utterly take it over, crowding out all else. THAT creates that mind-state, which then goes into memory. [So here we have a stuck trauma memory!]
What does the plays-outdoors part do with this? If it's strong enough, it can integrate with it. [So in that case, the memory is processed and all if fine.]
But that may not be the case. - [Then the memory is stuck and must be processed]
So - The creation of an EP could be called a split, but then that will be confused with how people often think of DID being created. Make sense. The term could and is used, but it really confuses everyone!
2. But maybe it was NOT a split. [again, this word can be confusing, but Tom uses it here to show how it could be and is used in some literature] Maybe plays-outdoors just got "turned off" by a more basic burst of energy - "I'm being attacked and I'm going to die!" Something new gets created at that point, and it may remain an entity to itself if it cannot integrate with some other part of the self. [This would be a created EP.]
So, which is it? I have no way of definitively answering that question. But, do we really need to?
