Research on parenting is thriving, having emerged over the past three decades as its own discipline within psychology and developmental science. Sandra Scarr’s work has been a catalyst. She has provided innovative and provocative ideas that challenge assumptions about the causes and consequences of parenting behavior, and the connections between parenting and individual differences in children’s developmental outcomes (Scarr, 1992, 1993). In particular, Scarr’s theory has prompted researchers to consider more seriously the role of child effects on parenting.
