A ZM could predict a future situation of the external reality, which has no
associated model. Such a situation can activate the PSM. To prevent this, the
ZM can make a would-be active-type model (WBAM). Such a model is not created
by direct interaction with the external reality. Such a WBAM acts as a
shielding model up to the last moment before the activation. After activation,
it becomes a normal ZM model.
A normal ZM is built in direct interaction with external reality. WBAMs can be
associated with the external reality without previous interaction with it.
Note: the emotion is defined in MDT as a transient situation between the
activation of the PSM and the moment when a normal suitable model is
activated. The activation of the PSM can be prevented by a good WBAM (of
course, if that situation was predicted by a main ZM).
WBAMs are included in the normal structure of the models and they are
controlled by it.
