The Psychology of Twinship - Book
Drawing from in-depth interviews with identical and fraternal (same-sex and opposite-sex) twins ranging in age from 15 to 65, The Psychology of Twinship (Second Edition: Northvale: Jason Aronson, Inc. 1997) explores the emotional development of twins, their relationships with each other, and how others experience them. The book is unique in its interest in the psychology of twins’ experience rather than twins and the influence of genetic makeup.
