establishment of developmental levels as well as the establishment of the
genetic relationship between levels and their formal aspect of

In developmental psychology there is an upward developmental direction
and movement in the direction of increasing differentiation from level to
level.  Along with the increasing differentiation there is an increasing
subordination of earlier content and a hierarchization of events and

In the area of feelings for example, this differentiation occurs from the
sensori-motor to the body signal system to linguistic concepts as we
progress in development.  The sensori-motor and body signal system
becomes subordinated to the higher conceptual levels and is
hierarchically integrated into the whole emotional response system with
increasing development.

The more differentiated and  organized the mental structure of an
organism the more flexible or plastic the behavior becomes.  The less
differentiated and hierarchically patterned the more rigid yet less stable
the behavior becomes.  Stability of behavior requires flexibility of
response in order to preserve the functional equilibrium of the organism..
