1. Assumptions about system
There are 4 assumptions of system:
1. First, there is “organization, interaction, interdependency and integration of the parts and elements of behaviors
that go to make up the system ”
2. A system “tends to achieve a balance among the various forces operating within and upon it', and that man strive
continually to maintain a behavioral system balance and steady state by more or less automatic adjustments and
adaptations to the natural forces impinging upon him.”
3. A behavioral system, which both requires and results in some degree of regularity and constancy in behavior, is
essential to man that is to say, it is functionally significant in that it serves a useful purpose, both in social life and
for the individual.
4. Last, “system balance reflects adjustments and adaptations that are successful in some way and to some degree.”.
Assumptions about structure and function of each subsystem
“from the form the behavior takes and the consequences it achieves can be inferred what “drive” has been
stimulated or what “goal” is being sought”
Each individual has a “predisposition to act with reference to the goal, in certain ways rather than the other ways”.
This predisposition is called as “set”.
Each subsystem has a repertoire of choices or “scope of action”
The fourth assumption is that it produce “observable outcome” that is the individual’s behavior.
