The presented models rather are of a didactical value. They are an attempt to present the complicated expressions of the behaviour disorders in a clear and simple form from the viewpoint of the motivation therory. It is clear that, as is the case with every scheme, they simplify the problems. However, it appears to us that the attempt of a synthesis almost always leads more or less to a schematisation in order to show the phenomena in a more generalised, clear form. An attempt has also been made to extract from the manifold data and theroies the "rational nuclei" and, departing from the phenemonological descriptions of the behaviour disorders, to find with their help a psychophysiological and pathopsychophysiological explanation.
