This paper has two general sources: my own clinical psychoanalytic work extending over about four and one half decades; and consideration of certain outstandingly influential ideas in our literature: first, those of the pioneer contributors, and then those of certain more recent writers, whose views have sometimes exhibited important differences from those widely held in the past. I try to evaluate the two groups--in their occasional overlapping and important divergences, in relation to my own clinical experience. A certain general position of my own emerges from such process inevitably; but it is far from "revolutionary." Indeed, the contrary is more largely true. In extreme anticipatory condensation--what I do propose, from my own reflections, is the preeminent importance of an archaic characterological core in depressive illness.  相似文献

The analysis of behavior sequences can be a useful technique for understanding family process and has been increasingly employed as a result of developments in family theory. Some of the most popular sequential analytic methods are reviewed, and problems of applying these methodologies to investigations of family interaction are discussed. Independence-of-observations, nonstationarity, and autocontingency are differentiated as three distinct types of serial dependence. In addition, issues concerning the choice of data type, analysis of low base rate behaviors, and the decision as to whether to correct for base rates are considered. Guidelines are presented for dealing with each of these issues in the context of the research or clinical question being addressed.  相似文献

A cross-cultural study of psychological differentiation of Canadian and Pakistani high school students was undertaken to examine the nature of psychological differentiation in relation to differences in age/grade, gender, and academic programs. The study involved 707 Canadian students from grades 6, 8, 10, and 12; and 349 Pakistani students from grades 8, 9, 10, and 12. The Group Embedded Figures Test was employed as a measure of the field-dependence-independence cognitive style. Analyses of data included two-way and three-way analyses of variance to determine the effects of grade, gender, and academic program upon GEFT scores. Differences in psychological differentiation between high school students in the two cultures were discussed in terms of Berry's eco-cultural model.  相似文献

Interventions were employed to program maintenance following correspondence training. The use of reinforcement of verbalization and a mixed sequence of procedures designed to establish indiscriminable contingencies was evaluated in multiple-baseline designs across subjects and behaviors. The results indicated that target behaviors were maintained under less intrusive interventions and in the absence of programmed contingencies during extended follow-up conditions. The results are discussed in terms of changes in reinforcement schedules established in maintenance interventions.  相似文献
