The problems of studying families arise from the difficulty in studying systems where there are multiple elements interacting with each other and with the child. How should this system be described? Still other problems relate to indirect effects; namely the influence of a particular dyad's interaction on the child when the child is not a member of the dyad. While all agree that the mother-father relationship has important bearing on the child's development exactly how to study this--especially using observational techniques--remains a problem. While progress in studying the family has been slow there is no question that an increase in interest in the family systems as opposed to the mother-child relationship is taking place. This has resulted in an increase in research on families and their effects. This volume by leading figures in child development on families attests to the growing sophistication of the conceptualization and measurement techniques for getting at family processes. The third in a series that aims to address topics relevant to the developmental problems and developmental disabilities of retardation this volume is divided into two parts. Section 1 presents basic family processes and approaches for describing family dynamics. It deals with these issues from a broad perspective including studying families at dinner families in different cultural contexts and the understanding of family in nonhuman primates. Section 2 looks at family processes in the service of studying families at-risk. The risk factors include poverty malnutrition and developmental delay and retardation. The study of family processes in these contexts provides data on family dynamics as well as how these dynamics impact on the children's developing competence. This volume will be informative for researchers clinicians and educators from a variety of disciplines and settings. The editors' aim is to bring a greater clarity to issues concerning the family life of children and highlight new research and possibilities for intervention. . Language: English
