Dr. Mercy recorded this program as a tribute to her mother Margery Wing Sisson Runyan who died on April 2, 2011 in Dayton, Ohio surrounded by her family at the age of 91. Mother Margery and another daughter Anne were guests on an earlier Twin Talk program entitled Family Secrets available in the archives. Dr. Mercy speaks about her mother’s life and then diverges into a discussion of ‘attachment’ in primary relationships. Twins are believed to bond more closely with each other than the mother. Dr. Mercy reviews the attachment theory of John Bowlby, including the types of attachment (secure, ambivalent, avoidant), the problems related to insecure attachment, and methods to ameliorate related issues in psychotherapy.
