Ariel Knafo is a professor of developmental social psychology in the Psychology Department at The Hebrew University of Jerusalem. One of his main lines of research concerns the development of personality and particularly altruism, empathy and other aspects of pro-sociality. For that matter, he studies the genetic, environmental and combined contributions to empathy and pro-social behavior, using questionnaire, experimental and observational designs.
He is interested in all potential influences on individual differences in social behavior and values. He investigates how values develop across contexts, cultures, and families. Another line of research studies concerns parent-child as well as child-parent influences, and in particular how children's genetics affect their own temperament and how parents react to them. The complex pattern of parent-child and genetic-environmental reciprocal or circular influences is studied with a twin study as well as with a study following families from pregnancy to children’s age 3. His aim is to combine behavior genetics and social-personality psychology approaches, with a developmental perspective to provide a comprehensive view of child and adolescent development and behavior.
