New Understandings of Twin Relationships

From Harmony to Estrangement and Loneliness
Barbara Klein
Stephen A. Hart
Jacqueline M. Martinez

This book 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 township 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.
