Dr. Driscoll conducts a test to determine whether empathy is best explained by nature or nurture
She compares empathic responding by monozygotic twins, dizygotic twins, and twins of both types reared apart, and their siblings (adoptive and biological).

Empathic responding is linked entirely to genetic factors. b. Empathic responding is the result of both nature and nurture in equal parts. c. Empathic responding is largely the result of nurture or environmental influences. d. Empathic responding is entirely determined by nature.
