Determinants of Behavioral Development documents the proceedings of the International Society for the Study of Behavioral Development's first symposium at the University of Nijmegen in The Netherlands, 4 July 1971. The symposium was planned under the general theme ""Genetic and Social Influences on Psychological Development."" Perhaps the major contribution of the Nijmegen Symposium, and of this volume, is the establishment of a new linkage between European and American research in developmental psychology.
This volume contains 64 papers organized into eight parts. The papers in Part I deal with issues of research strategy. Part II presents studies on biological determinants of development. Part III examines cultural and societal factors in development while Part IV focuses on the concepts of deprivation and enrichment. Part V presents selected studies on infants. Part VI investigates cognitive process in child development. Part VII contains papers on socialization themes while Part VIII takes up adult development.
