Attachment and Health
John Bowlby and Mary Ainsworth developed attachment theory in the 1960s while investigating the effects of maternal separation on infant development. The development of the Strange Situation task in 1965 by Ainsworth and Wittig allowed researchers to systematically investigate the attachment system operating between children and their parents. The Strange Situation involves separating infant-parent dyads and observing infant behaviours upon reunion. Infant behaviour tended to follow patterns, leading to the development of three attachment categories: Secure, Anxious-Avoidant, and Anxious-Resistant. In 1990, Ainsworth added a new category, championed by Mary Main, called Disorganized/Disoriented attachment, characterized by its less reliable pattern of behaviour.
Attachment theory
Although attachment theory has become a major scientific theory of socioemotional development with one of the widest research lines in modern psychology, it has, until recently, been less used in clinical practice.
The attachment theory focused on the attention of the child when the mother is there and the responses that the child shows when the mother leaves, which indicated the attachment and bonding of the mother and the child. The attention therapy is the done while the child is being restrained by the therapists and the responses displayed were noted. The tests were done to show the responses of the child.
