The introductory essay prepares the reader for a deeper understanding of the contributions of each of the pioneers. Mamie Phipps Clark had a profound impact on the education of American children. Robert W. White pioneered a new approach to the study of persons across the lifespan. Lois Barclay Murphy’s perspective on the strengths of developing children foreshadowed later developments in positive psychology. Florence Goodenough pioneered new testing methods for children. John Paul Scott was a pioneer in the field of behavior genetics. The book also highlights the many contributions of European pioneers: Jean Piaget, Charlotte Bühler, Heinz Werner, and Lev Vygotsky. Their contributions were carried forward by J. McVicker Hunt in the U.S. and Helena Antipoff in Brazil. Arnold Gesell’s film studies of children’s development remain a landmark accomplishment. Lawrence Kohlberg pioneered the study of moral development across the lifespan. Roger Barker’s studies on aggression and leadership among children eventually led to the development of ecological psychology. Eleanor "Jackie" Gibson was famous for her work on the "visual cliff" and for her research on perception and development. Finally, Sidney Bijou had a long career delineating ways to improve the lives of children. Pickren’s concluding essay draws connections between the pioneers and how they contributed to the advancement of the field.
