Security in Infancy, Childhood, and Adulthood - A Move to the Level of Representation

We are grateful to the Institute of Human Development, Berkeley, and to the Society for Research in Child Development for funding that made the study of our sample at 6 years possible. In its earlier phases, the Social Development Project was supported by the William T. Grant Foundation, by the Alvin Nye Main Foundation, and by Bio-Medical Support Grants 1-444036-32024 and 1-444036-32025 for studies in the behavioral sciences. The Child Study Center at the University of California was invaluable in its provision of subjects and in the training provided for our observers and examiners. The National Center for Clinical Infancy Programs provided support and assistance to Nancy Kaplan. This project would not have been possible without the direction and assistance provided by Donna Weston and by Bonnie Powers, Jackie Stadtman, and Stewart Wakeling in its first phases. For the initial identification of infants who should be left unclassified-an identification critical to the present study-we gratefully acknowledge both Judith Solomon and Donna Weston. Carol George participated in the designing of the sixth-year project; Ruth Goldwyn served as adult interviewer; and Ellen Richardson served as the child's examiner. The videotapes and transcripts of the sixth-year study were analyzed by Jude Cassidy, Anitra DeMoss, Ruth Goldwyn, Nancy Kaplan, Todd Hirsch, Lorraine Littlejohn, Amy Strage, and Reggie Tiedemann. Mary Ainsworth, John Bowlby, Harriet Oster, and Amy Strage provided useful criticism of earlier versions of this chapter. The overall conceptualization was substantially enriched by suggestions made by Erik Hesse.
