Internal working model of attachment
Internal working model of attachment is a psychological approach that attempts to describe the development of mental representations, specifically the worthiness of the self and expectations of others' reactions to the self. This model is a result of interactions with primary caregivers which become internalized, and is therefore an automatic process. John Bowlby implemented this model in his attachment theory in order to explain how infants act in accordance with these mental representations. It is an important aspect of general attachment theory.
Attachment therapy
Attachment therapy prospered during the 1980s and '90s as a consequence of both the influx of older adopted orphans from Eastern European and third world countries and the inclusion of reactive attachment disorder in the 1980 Diagnostic and Statistical Manual of Mental Disorders which attachment therapists adopted as an alternative name for their existing unvalidated diagnosis of attachment disorder.
