ABSTRACT
The biological processes of growth and differentiation during puberty effect changes in the structure and in the functioning of the organism. These changes occur in a typical and sequential order, called maturation. The same applies to the psychological changes of adolescence. These, too, follow a developmental pattern but of a different order, since these changes draw content, stimulation, aim, and direction from a complex interplay of inner and outer impingements. What we, eventually, observe are new stabilizing processes and alterations of psychic structures, both of which are the result of adolescent accommodations.
