There is a game based on this idea: one builds a model, and the other has to guess what the model is. To do this, he/she has to ask questions to be answered only by yes and no.
T2. Test for detection of paranoia.
An individual accepts a change in a stable model, if the external reality imposes it. In a practical situation, the person interacts with external reality and builds a model, which gives good predictions on the external reality. At some point, an element of the external reality is changed. If the person detects the change and corrects the model, as well as the other interconnected models, this is a good indication of normality. For a person suspected of paranoia, the model used would be the one supposed to be the OMPSM.
Paranoid subjects can distort the external reality unlimitedly to make it compatible with their OMPSM. As a consequence, the test tries to see if the person suspected of paranoia will modify the supposed OMPSM.
To be applicable, the test as described above, needs to take into account a design deficiency of the brain, as given in the general theory. Any image model has a basic problem: on an image model one can't see the importance of an element or a relationship. The image model remains harmonic for an infinity of values of importance, given to the elements or relations. Due to this issue, the paranoid subjects do not realize the presence of their illness.
Except these classical psychiatric illnesses, there are illnesses produced by dynamical and transitory instabilities of the brain. The illnesses given by dynamical or transitory problems refer to the loss of models stability in special conditions or at certain moments of time.
The XZM (illegal models) could also explain a series of problems. The general theory addresses this issue.
We'll make another note here. The theory is applied here in particular to normal individuals. The pathological cases are not generally considered at this level. It is actually absurd to study pathological cases in the absence of a good model associated to normal persons.
ETA 16: Dreams
The dreams are associated to image model development. Such models are built, based on the available data in the brain and not by direct interaction with the external reality. We call the source of data for the dreams as Quasi- External-Reality. QER could take information from any available model of the brain to build and develop the dream-model. QER is invariant during a dream.
