SYSTEMS THEORY
  • Whitchurch, G. G., Constantine, L. L.
    (1993). Systems theory. In P. G. Boss, W. J.
    Doherty, R. LaRossa, W. R. Schumm, S. K.
    Steinmetz (Eds.), Sourcebook of family theories
    and methods A contextual approach (pp. 325-352).
    New York Plenum Press.

Three Distinct But Closely Interrelated
Theoretical Legacies
  • Information theory focuses on the reduction of
    uncertainty which is achieved by the acquisition
    of information.
  • Cybernetics a science of communication concerned
    with the transmission and control of information
    it examines the communication and manipulation of
    information in various systems.
  • General Systems Theory (GST) interested in
    systems in general family systems theory is an
    extension of this branch.

Definitions and Terms
  • Three Uses/Definitions
  • General Systems Theory (GST) is used to explain
    the behavior of a variety of complex, organized
    systems.
  • GST is also a process of theory construction
    which focuses on building universal concepts,
    postulates, and principles.
  • GST, as a worldview, emphasizes
    interrelationships between objects.
  • Terms
  • Isomorphism Refers to equivalence of form there
    is a one-to-one correspondence between elements
    and relationships.
  • Cybernetic system systems with feedback.

4
Core Assumptions of General Systems Theory
  • GST Has Potential for Unifying Science suggests
    that there are unifying principles in every
    discipline GST is a way to consider isomorphism
    between them.
  • A System Must Be Understood as a Whole
  • Von Bertalanffy promoted the notion that a
    family, or any system, is greater than the some
    of it's parts.
  • Lewin the whole is different from the sum of
    it's parts.
  • Human Systems are Self-Reflexive
  • Human systems are characterized by their ability
    to make themselves and their own behavior the
    focus of examination this is self-reflexivity.
  • Self-reflectivity
  • permits humans to examine their systems and set
    goals.
  • permits humans to examine social influences on
    systems and behaviors, rather than naively
    accepting them as natural.

Research and Theory Foci
  • Ongoing Family Processes
  • Transactional patterns (e.g., predictable
    behavior sequences).
  • Shift focus from individual to the family.
  • Topics
  • family functioning,
  • family communication,
  • family conflict,
  • separateness and connecetedness,
  • cohesion,
  • adaptation to change.
  • Example of research questions (from Montgomery
    Fewer, 1988)
  • What elements of a social system are influenced
    by other parts of the system how does one
    element of a system recursively influence the
    whole system?
  • How does the behavior of different components fit
    together?
  • How does the fit between systems affect
    functioning?
  • What is the Relationship of Family Systems to
    Other Systems

Major Contemporary Concepts of General Systems
Theory
  • Interdependence/Mutual Influence
  • Equifinality
  • Definition the ability of a system to achieve
    the same goals through different routes (e.g., we
    may take different roads to campus but we all
    arrive at the same place).
  • Communication patterns are organized into
    feedback loops which affect goal-setting behavior
    in systems.
  • Hierarchy
  • The layering of systems of increasing
    complexity, including
  • Subsystems smaller parts of the same system.
  • Systems
  • Suprasystems larger systems (e.g., economic and
    political system).
  • Controversy disagreement about definition of
    sub- and supra-systems as well as identification
    of components.

7
Major Contemporary Concepts of General Systems
Theory (cont.)
  • Boundaries and Open/Closed Systems
  • Boundaries define membership in a system.
  • Boundaries also represent the point of contact
    between the system and other systems.
  • Boundaries vary in degree of permeability, the
    degree to which they control the flow between
    systems.
  • Customary approaches to operationalizing
    boundaries
  • Assessment of permeability and cohesion.
  • Emotional connectedness between family members.

8
Contemporary Concepts (cont.)
  • Feedback and Control
  • Feedback loop
  • Path of communication in a system.
  • Feedback is considered either positive or
    negative based on the effect it has on the
    system, not on its content.
  • Types of feedback loops
  • Negative
  • feedback is used to maintain homeostasis. This
    type of feedback has also been called constancy
    loops and deviation-attenuating loops.
  • Morphostatic feedback refers to feedback which
    promotes maintenance of existing structure.
  • Positive feedback used to promote change.
  • These types of feedback are also referred to as
    deviation-amplifying loops or variety loops.
  • Morphogenic feedback refers to feedback which
    produces change in the system.

Examples of Research Emerging from General
Systems Theory
  • Marital and Family Interaction
  • Hess and Handel (1959) integrated GST and
    symbolic interactionism to examine the family as
    a system that socially constructs its reality.
    They suggested that there are five essential
    processes of family interaction.
  • Comparison of family interaction patterns between
    normal and schizophrenic families (Mishler
    Waxler, 1968).
  • Family Dysfunction individual patterns of
    dysfunction are attributed to family interaction
    patterns.
  • Alcoholism Steinglass and Wolin have integrated
    a family development and systems approach,
    suggesting that alcoholism influences families in
    stages which accounts for patterns of alcoholism
    in families.
  • Family violence systemic explanations are
    controversial. This research suggests that the
    failure to leave an abusive situation is a form
    of positive feedback.

10
Examples of Research (cont.)
  • Marital and Family Taxonomies
  • Olsons Circumplex model
  • Three dimensions create sixteen relationship
    types the three dimensions are
  • Cohesion
  • Adaptability
  • Communication
  • Three general types of relationships
  • Balanced
  • Mid-range
  • Extreme
  • In general, research has revealed that balanced
    families will function more adequately than the
    other types of families.
  • It has been criticized for not including a
    dimension for competence.

11
Examples of Research (cont.)
  • Marital and Family Taxonomies (cont.)
  • The Beavers systems model examines family
    competence (e.g., healthy, mid-range, and
    severely dysfunctional).
  • Typologies melding systems with symbolic
    interactionism develop, for example, a typology
    based on the effect of family members shared
    perceptions about their social environment
    (symbolic interactionism) on the social
    environment (a systems construct) (Reiss, 1981
    see also Constantine, 1986 Constantine Israel,
    1985 Fitzpatrick, 1976, 1988).

12
Limitations of General Systems Theory
  • General Criticisms focus on application of
    systems theory.
  • GST is too vague and general, making it difficult
    to operationalize and evaluate empirically.
  • Criticized for poor explanatory power because,
    although it provides conceptualization, it is
    difficult to clearly identify and measure
    constructs.
  • Criticism of subtle assumption that all parts of
    a system have equal power.

13
Limitations of General Systems Theory (cont.)
  • Feminist Critique
  • Limited recognition of power in family systems
    which obscures the privilege of dominant groups.
  • Systemic constructs often reflect sex bias.
    Enmeshment is pathologized, for example, while
    differentiation is promoted. This devalues a way
    of relating that is common to women.
  • Clinically, emphasizes therapist neutrality.
  • Ironically, it is viewed as not systemic enough.
  • Interdisciplinary scholarship has demonstrated
    that all cultures utilize gender and generation
    as fundamental categories of organization, but
    systems theory ignores gender concerns.
