I am a professor of developmental social psychology at the Psychology Department, The Hebrew University of Jerusalem. My main research interests concern the development of individual differences in social behavior and personal values, focusing on the effects of heredity and parenting on children’s development, as well as on the impact of children on their parents. I earned a BA in psychology and a master’s degree in social psychology at the Hebrew University in Jerusalem, where I also performed my doctoral research: “Value transmission in the family: Processes of perception and acceptance of parental value,” supervised by Prof. Shalom Schwartz. Afterwards I had a postdoctoral Kreitman fellowship in educational psychology at the Ben Gurion University of the Negev, Israel, and a postdoctoral fellowship in behavior genetics at the Social, Genetic, and Developmental Psychiatry Research Centre, at the Institute of Psychiatry, King’s College London. Nowadays, my studies on values focus on how children’s values are affected by their own genetics, as well as their culture, social context, and the values of their parents. In a recent paper I have demonstrated how children’s values are affected by their genetic inheritance. I also address the consequences of values on behavior. Cross-cultural research conducted with my colleagues, for example, demonstrated how values of Arab and Jewish adolescents in Israel were related to their levels of violence at school and how the overall level of violence in schools affected the degree of relevance of values in behavior. The research on values led me to a focus on children’s prosocial behaviors such as helping, sharing, and empathy, which often underlies these behaviors. In a twin study with my colleague Caroline Zahn-Waxler (2008), I have showed how empathy develops as a personality or temperament trait, in the second and third year of life. The study showed that the effects of the family environment shared by children reared together weaken with age, whereas genetic effects on empathy emerge in the second half of the second year of life. With our lab’s twin study (2011), I examined the prosocial behavior of 3.5 year-old children in a series of assignments that allowed them to help and to share resources. This was the first demonstration in a lab setting of the heritability of children’s prosocial behavior. The study found no direct relationship between children’s prosocial behavior and the parenting they received from their mothers. However, when children were divided by the presence of a specific allele of one of the dopaminergic genes, the parenting-prosocial behavior relationship was found, but only among carriers of this allele. In recent years, I have been engaged in research on how children’s genetics affect their temperament and how parents respond to them. My aim is to combine behavior genetics and social-personality psychology approaches with a developmental perspective to provide a comprehensive view of child development.
