Interactive typology in depression according to cognitive theory and systemic theory.

Both systemic and cognitive theories agree upon the importance of early learning in the development of depressive personality. The two theories disagree upon the meaning they give to the early experiences. According to cognitive theory the emotions bound to a significant and not reparable loss turn themselves into a pursuit of autonomy in order to prevent further grieves. In the grown-up person if autonomy is not reached or is lost, a depressive episode will rouse. According to the systemic theory, children learn emotions and behaviours of a depressed parent. The child also learns by himself or through the healthy parent the feeling of importance/inability to help. The grown-up person will make use of the depressed behaviour when he will feel unable to face by himself critical life events or to elice to care or attention by the partner.

The relationship between systems theory and community psychiatry.

General systems theory, when applied to human personality and behavior, considers the human system to be an active, open one in which personality develops through interaction with other systems; problems within one system can produce ripple effects in others. Community psychiatry sees the roots of most mental disorders as being in disturbances within the network of interacting systems. The author believes that community mental health centers, with their multifaceted approach to treatment and prevention, reflect the health profession's efforts to deal with the mental health problems of a community in a systems-oriented way. Although the CMHC movement has weaknesses, he feels they do not stem from the basic concepts behind the centers, but from the inadequate implementation of those concepts. He considers four major interfacing variables that are relevant in determining a center's capacity to survive and to function.

A systems theory approach to a case of anorexia nervosa.

Systems theory views mental and psychosomatic illness as the natural consequences of a dysfunctional human interactional group. The symptom chosen is affected by the symptom carrier's age, sex, and unique individual characteristics. However, the reason the symptom develops and is maintained is to be found in the system(s) of which the symptom carrier is a part. A human system consist of two or more individuals who have an ongoing, often goal-directed, relationship with each other. The most important human system today is undoubtedly the family. The welfare of the individual is usually related to membership in a vital, well-adjusted family. A dysfunctional family easily becomes dependent on mental or behavioral deviations in one of its members as a means of preventing disintegration. We hope this article's description of a typical treatment situation will demonstrate how a systems theory approach differs from other forms of family therapy in its evaluations and techniques.

General systems theory: implications for theory and action in occupational therapy.

This paper presents a description of the transformation of science under General Systems Theory, and the relationship of this transformation to the field of occupational therapy. Changes in scientific methods of proof and in scientific laws that underlie theory are discussed. The paper presents a scale for recognizing complexity in phenomena and for analyzing the appropriateness of theories designed to explain the phenomena. It also presents the theory of open systems as an alternative to mechanistic explanations of human behavior.

Family functioning during a critical illness: a systems theory perspective.

In this article the effects of critical illness on family functioning are described within a systems theory framework. As identified in the literature, family vulnerabilities and strengths that impede or support family functioning during the time a member has a critical illness are discussed. Strategies that nurses can use to assist families of critically ill patients are explored. A challenge to expand family-centered care across various settings is extended.

A systems-theory approach to the analysis of multiexponential fluorescence decay.

A mathematical model of the fluorescence decay experiment based on linear systems theory is presented. The model suggests an experimental technique that increases the probability of correctly determining the decay constants of a multicomponent system. The use of moment methods for data analysis improves accuracy by combining information obtained from several discrete experiments. Examples are presented to show that the analysis of a three component system composed of known standards is improved as the number of experimental determinations is increased from one to four. The discrete measurements are made by changing the excitation and emission wavelengths.

Shame and other anxieties associated with breast-feeding: a systems theory and psychodynamic approach.

It is easy to be over-simplistic about breast-feeding--what determines the choice of the breast; what causes rejection of breast-feeding as a feeding method; what determines success and what its failure? In fact, a bewildering range of factors, physical, psychological and sociological play a part. How can these be related to each other and ordered in general and for the individual? A general systems theory approach, in which the elements are envisaged as interacting dynamically, seems to offer a possible satisfactory explanatory model. Moving from social systems to the individual's intrapsychic system helps to understand the complexity of emotions aroused about the breast and breast-feeding. Shame and anxieties are seen to arise from the confluence of life history and current events. Intervention is necessary at many levels--societal, family and individual--if breast-feeding is to be re-established as the feeding method of first choice.

Alcoholism and systems theory: building a better mousetrap.

A considerable body of research evidence has accumulated in the alcoholism field with respect to when persons who overly rely on alcohol modify their behavior and seek alternate ways of dealing with life. It is the purpose of this paper to identify a number of these factors and relate them to a theoretical perspective that, while not new, is of relatively recent vintage for alcoholism specialists. That perspective is General Behavior Systems Theory (GBST), and it will be contended that its basic postulates comprise a framework that is especially congruent with the findings related to when alcohol-dependent persons change. As such, it provides a set of ideas which offer more fruitful guidelines for assessment and intervention than those resulting from exclusive reliance on other extant models (see Siegler et al., 1968; Miller and Barlow, 1973), in particular, the traditional and predominant illness conception.

A neural systems theory of schizophrenia and tardive dyskinesia.

Some systems ideas applied to individual persons are used to try to explain symptoms of schizophrenia and a syndrome of uncontrolled fragments of movement which sometimes occurs as a side effect of chronic, antipsychotic drug therapy. The behavior of normal organisms may be conceptualized in three echelons of control, with each successively higher echelon organizing, by selective disinhibition, semiautonomous, spontaneous fragments of activity which comprise the next lower echelon. It is hypothesized that schizophrenia involves a deficiency of inhibition by the frontal cortex, first echelon, on the corpus striatum, second echelon. This results first in insufficiently integrated fragments of behavior, and second in premature associative linkages among active elements. First echelon control develops as a normal person matures and gradually loses some of the playful activities of childhood. It is hypothesized that by disrupting certain aspects of activity in the corpus striatum, neuroleptic drugs reduce schizophrenic symptoms but also reduce the capacity of the second echelon to inhibit and integrate the smaller behavioral fragments wired into lower parts of the brain, third echelon. This results in uncontrolled movements. Though many researchers already favor the hypothesis that neuroleptic drugs act on the corpus striatum, the broader theory presented here is new and depends in large part on general living systems considerations. Emphasis is on conceptual decomposition of the integrated behavior of a whole organism into less complex subsystems. Individually, these have neither too much nor too little complexity to yield a plausible model. Some experimental predictions and predictions about possible therapies are made from the theory.

Conceptual frameworks and the philosophical foundations of general living systems theory.

The continued expansion and fragmentation of biological disciplines impede education, communication, and efficient advance of biological research. Reversing these trends may require a unification of theories and concepts from all levels of biological organization. One form of this unification is the statement of generalizations that apply to all living systems. We explore the philosophical foundations of general theories of living systems by analyzing conceptual frameworks as they apply to biology. This analysis examines the relation of empirical observation, theories, and conceptual frameworks within the context of an individual scientist's conceptual continuum. Also presented are a small set of translevel generalizations that articulate our conceptual framework of living systems in terms of organismic system organization, the environmental system-organismic system dyad, system capacity, and system incorporation. A set of procedural rules are stated which suggest minimum criteria for the evaluation of the explanatory adequacy of biological theories. The relation of this work to other similar analyses and syntheses of biological knowledge is discussed.
