The inverted function blocks in the poly-tact model, or How to ignite a SEI

The type activation model (it can also be called the "poly-tact" or horizontal model) was developed by Aushra back in the 80s. This is a model of how incoming information is processed.

There are the Vital and the Mental rings in the Model A. Along the Vital ring, movement proceeds through functions 5-6-7-8, and along the Mental ring — through 3-4-1-2. This is essentially the system’s "startup point."

The essence is that there are four blocks (poly-tacts). These are Inverted Blocks that merge two complementary sides of the same aspect, forming a unified, macro-level perspective:

1. Correspondence Function Block (Role + Suggestive functions)
2. Achilles Function Block (Vulnerable + Activating functions)
3. The Place Function Block (Program + Observational functions)
4. Creativity Function Block (Creative + Demonstrative Functions)

An Inverted Block can be active or inactive.
