The psychological theory of attachment was first described by John Bowlby, a psychoanalyst who researched the effects of separation between infants and their parents (Fraley, 2010).  Then in the 1970's, psychologist Mary Ainsworth expanded greatly upon Bowlby's original work.  

In this Episode, Dr BB shares with audience Bowlby's original finding of the three ways how infants behave upon reunion with the parents: secure attachement; anxious-avoidant; anxious-resistant attachment; and in later years, researchers added a forth attachment style to the list: the disorganized attachment (Kennedy & Kennedy, 20040.

It is easy to see from Dr BB's descriptions of behaviors and emotion regulation how attachment style in childhood can lead to relationship problems in adulthood.  Indeed, it is clear how these attachment styles in childhood lead to attachment types in adulthood.  It definitely benefits the audience to further explore their own attachment styles so to be aware of their own behaviours and how they affect their close relationships.
