From General Laws To Singularities

This article comprises several sections. The first is devoted to an explanation of a number of notions stemming from work by Ilya Prigogine and others on open systems far from equilibrium. As a result of this work, I have been able to stand back from the traditional approach employed in family therapy, that of open systems at equilibrium (the theory of Ludwig von Bertalanffy). The second section describes a clinical example based on elements close to Prigogine's theories. In the third part I develop an approach that--although continuing to draw on Prigogine's work--is much more closely linked to the research I have carried out with Félix Guattari over recent years. In this part I attempt to study a level that, in my view, has too often been left outside the field of inquiry: that of couplings between "singularities" of members of the family system and the therapist. A clinical case is presented in which this "semiotic" level, as Guattari terms it, is used together with that of the "intrinsic rules" of the system. Finally, I propose a few avenues of inquiry and research on the basis of the concepts presented.     

Older adolescent females' knowledge of child development norms

This study, the first of three designed to investigate different age groups' knowledge of developmental norms of children, focused on older adolescent female university students. Data were collected from 280 midwestern university students through a questionnaire consisting of 16 items focusing on physical and social development of children from birth to three years of age. Results showed that knowledge of normal development was both over- and underestimated regardless of age of student or year in school. These findings are discussed within the context of the importance of knowledge of developmental norms for future parents.     

The Velten Mood Induction Procedure and cognitive models of depression: A reply to Riskind and Rholes (1985)

In a recent article (Clark, 1983), I concluded that it is invalid to use the success of the Velten Mood Induction Procedure as evidence for cognitive theories of depression. Riskind and Rholes (1985) challenge this conclusion. Their arguments are discussed and critically evaluated.     

Pursuing and distancing: the construct and its measurement

Although the concept of interpersonal pursuing and distancing has been introduced and used clinically, the lack of a reliable and valid measure has deterred its more formal investigation and relevance to personality theory. The Pursuing-Distancing (P-D) Scale, a 92-item measure of the behavioral expression of these characteristics, was developed. Evidence for internal consistency as well as internal support of construct validity is presented and discussed. An 80-item revised scale is available from the authors and is currently being evaluated in a variety of external validation settings.
