have suggested that a moratorium on A-B research deserves serious consideration. I n anticipation of this possibility, and to attem t to clarify the confusing findin s with regard to the nature of A-B and tge relationships of. A-B and Fiel! Dependence, the authors initiated this study of the ecological framework of a psychiatric ward and the role charactenstics of both staff and atients (N = 99). The results of the study sup orted the two major hypotieses that were derived from a functional rtnabsis of the demand characteristics for both patients and staff on an inpatient psychiatric unit. First, it was found that the staff scored higher on type A characteristics than on type B characteristics, and, second, it w w found that the patients scored higher on type B characteristics than on type A characteristics.This study was carried out to clarify mixed findings with regard to the nature of A-B personality types and the relationship between A-B types and Field Dependence (FD). The authors investigated A-B and F D variables by exploring the pattern of personality constructs and role characteristics of both staff and patients on a psychiatric ward of the University of Minnesota Teaching Hospital to determine whether the situational demands of a hospital setting could provide a new perspective on previously confused findings.The first article on the A-B therapist distinction was defined operationally by using a relatively small number of items on the Strong Vocational Interest Blank. On the basis of these items, it was found that A type therapists were highly successful in treating patients with schizophrenic disorders. Whitehorn and Betz (1954) and RlcNair, Callahan, and Lorr (1962) indicated that type B therapists were found to be more effective in treating neurotic patients. Beta's (1967) review of the literature supported the original findings, but since that time substantial literature has accumulated. The authors were especially interested in the role of ecology in regard to the A-B therapist distinction and how it relates to the relationship between A-B and FD.The role and nature of "ecology" in the field of psychology requires an assessment of its utility.The ecological viewpoint needs clarification. Ecology emerges as a plea for expanding our range of clinical problems, our methods, our levels of analysis, and our choice of settings in which to study. Ecology offers psychology new opportunity to use the "ecological framework" to study the nature of the A-B personality type distinction and its relative relationships to FD. An inpatient psychiatric ward would/should prove an excellent field setting to study patient, paraprofessional and professional roles within the nature of a particular ecological framework in order to understand better the nature of A-B and its relationship t o FD on a new perspective (McGurk, 1977).Although some investigators have remained convinced that the A-B variable is a viable research construct (Berzins & Suinn, 1975), other investigators have concluded that the A-B variable is not a ...
