1. General SystemsTheory: Answer "a system theory constitutes a way of explaining a unit such as a family as it relates to and interacts with other systems....it explain how each variable affects the whole and how the whole affects each part" 2. Concepts of the General Systems Theory: Answer System: one unit in totality for analysis; interdependency; the structure is the organization of the parts needed for effective function and measurable outcomes. Holism or Nonsummativity: the system is analyzed holistically and not in individual parts Interconnectedness: the system is interconnected with the environment in which it exists Social System:is a social organization with persons having interactions with defined boundaries Open System: all living systems must be interactive with the environment Closed System: does not need interaction with the environment to survive Hierarchy of Systems: each unit has a hierarchy that transcendsfrom a higher-level to a lower-level system; an identified system of study is called a target system of focal system. Boundaries: are lines of demarcation from systems,subsystems, and suprasystems; these boundaries can be porous or flexible to allow more or lessinteraction between the system and the environment. Input: isreceived from the environment and affectssurvival; it isthe source of output in the system. Output: occurs when a system monitors and processes its output. Feedback: ongoing monitoring of input and output in a system. Self-Regulation, Homeostasis, Steady State, and Equilibrium: self-regulation is a mechanism for managing the family's ability to balance and control input; when this occurs there is homeostasis, steady state and equilibrium. Differentiation: this process occurs for growth and change to occur; families need a balance of stability (morphostasis) and change to grow as a unit. Energy: increased energy is needed from the environment for systems with in- creased activity; energy is necessary for differentiation to occur. 3. Application ofthe General SystemsTheoryConceptsto the Family: Answer - Family: living social system; interdependent; family members in a single unit for
