Dr. Mercy interviews Dr. Nancy Segal, Professor of Psychology and Director of Twin Studies at the California State University, Fullerton, will be discussing twins switched at birth. As a fraternal twin, psychologist and researcher, Dr. Segal has been uniquely positioned to perform ground-breaking studies on twins including her work at the University of Minnesota with twins separated at birth and reunited in adulthood and her most recent study on the development of Chinese twins adopted internationally both apart and together. Her other research has included the behavioral similarities of virtual twins (same age unrelated children raised together) and the behavioral consequences of twin loss. Dr. Segal is considered one of the foremost experts on the nature versus nurture controversy based on her quantitative studies of twins’ behaviors. Dr. Segal will be prepared to discuss the nature of twin relationships, twin development, twins accused of cheating at school, and twin relationships within the family.

Dr. Nancy Segal has written seven books about twins. 

Dr. Segal has authored approximately 250 scientific articles and book chapters in addition to her many books. A recent paper won a 2007 Award for Excellence in Research from the Mensa Foundation. She is also an Associate Editor of Twin Research and Human Genetics, the official journal of the International Society for Twin Studies. She serves on the editorial boards of a number of journals, including Twin Research and Human Genetics, Evolution and Human Behavior and Human Ethology.
