Q&A | Jerome Kagan

Taking a new look at human development

Jerome Kagan has been at the forefront of developmental psychology since joining the Harvard faculty in 1964, and was once listed as the 22d most influential psychologist of the 20th century — right ahead of Carl Jung and Ivan Pavlov. His seminal work, “The Nature of the Child,” was published in 1984 and again in 1994. When he started to work on a third edition in his retirement, he decided that so much had changed, he needed to write an entirely new book. That book, “The Human Spark: The Science of Human Development,” was published in June.
