Editor's note: The parameters of adult development

Based on a recent extension of Heinz Werner's (1957) organismic-developmental theory (e.g., Wapner, 1987; Wapner & Demick, 1990, 1991), suggestions for the parameters of theJournal of Adult Development have been generated. These include the need for: (1) a focus on adult development at all levels of integration (biological, psychological, sociocultural); (2) increased examination of the interrelations among these levels as well as between the psychological part-processes ofexperience (cognition, affect, valuation) andaction over the course of adult development; (3) the complementarity of theory and empiricism, of basic and applied research, and of quantitative and qualitative approaches to methodology; and (4) transdisciplinary collaboration. Preliminary editorial policies are sketched; recommendations for any aspect of policy and procedure are strongly encouraged.
