Willard W. Hartup This volume amounts to an anniversary collection: It was 50 years ago that Lois Jack (1934) published the findings from what most investigators consider to be the first intervention study in this area. The experiment (later replicated and extended by Marjorie Page, 1936, and Gertrude Chittenden, 1942) concerned ascendant behavior in preschool children, which was defined to include: (a) The pursuit of one's own purposes against interference and (b) directing the behavior of others. Individual differences in ascendance were assumed to have some stability across time and, hence, to be important in personality development. But ascendance variations were also viewed as a function of the immediate situation. Among the conditions assumed to determine ascendance were "the individual's status in the group as expressed in others' attitudes toward him, his conception of these attitudes, and his previously formed social habits" (Jack, 1934, p. 10). Dr. Jack's main interest was to show that nonascendant children, identified on the basis of observations in the laboratory with another child, were different from their more ascendant companions in one important respect: They lacked self confidence. And, having demonstrated that, Dr. Jack devised a procedure for teaching the knowledge and skill to nonascendant children that the play materials required. She guessed, correctly, that this training would bring about an increase in the ascendance scores of these children."

What determines the focus of a researcher's interest, the sources of inspiration for a study, or the variables scrutinized? If we were to examine the antecedents of these decisions, they would surely emerge as accidents of circumstance--the personal experiences of the researcher, the inspiration of early mentors, the influence of contemporary colleagues--all tempered by the intellectual currents that nurture the researcher's hypotheses. Among the accidents that mold the careers of researchers is geographic location. The culture in which a research program emerges helps determine both its very subject and its method. The primary purpose of this book is to assist those interested in the scientific study of children's social competence in transcending the boundaries imposed both by geography and by selective exposure to the highly diverse schools of thought that have led to interest in this field. Most of these ideas were presented and exchanged at an Advanced Study Institute entitled "Social Competence in Developmental Perspective" held in Savoie, France, in July 1988. This Institute was attended by scholars from France, England, Northern Ireland, Germany, Italy, Norway, Spain, Portugal, Netherlands, Canada, the United States and Brazil. Those who participated will recognize that the metamorphosis from lecture to chapter has necessitated many changes. In order to accommodate the reader who may be unfamiliar with the field, more attention has been paid here to identifying the theoretical contexts of the research described.
