How do experiences shape what we bring into the world? In The Human Spark, pioneering psychologist Jerome Kagan offers an unflinching examination of personal, moral, and cultural development that solidifies his place as one of the most influential psychologists of the past century. In this definitive analysis of the factors that shape the human mind, Kagan explores the tension between biology and the environment.
Temperament is the single most pervasive aspect of us and our fellow human beings. We notice it; we gossip about it; we make judgments based on it; we unconsciously shape our lives around it. In The Temperamental Thread, developmental psychologist Jerome Kagan draws on decades of research to describe the nature of temperament-the in-born traits that underlie our responses to experience.
