New Understandings of Twin Relationships takes an experience-based approach to exploring how twin attachment and estrangement are critical to understanding the push and pull of closely entwined personal relationships.

Based on the research expertise of each of the authors (all identical twins in their own right), and vignettes from twins across the globe, this book describes the inner workings of the twin-world, showing how the twin-world creates experiences that are often more intense and intricately textured than those in the singleton-world. Chapters debunk myths surrounding twinship and analyze the developmental stages of the twin relationship as well as the effect of being a twin on one?s mental health from different perspectives. The authors articulate how attachment, separation anxiety, loneliness, estrangement, and the subjective experience of the twin and non-twin "other" impact behavior, thinking, and feeling.

Through its careful study of the many psychological challenges that twins face throughout their lifetime, this text will help psychologists, scholars, clinicians, and twins themselves attain a deeper understanding of all interpersonal relationships.
