Reactive attachment disorder
The broad theoretical framework for current versions of RAD is attachment theory, based on work conducted from the 1940s to the 1980s by John Bowlby, Mary Ainsworth and René Spitz. Attachment theory is a framework that employs psychological, ethological and evolutionary concepts to explain social behaviors typical of young children. Attachment theory focuses on the tendency of infants or children to "seek proximity" to a "particular attachment figure" (familiar caregiver), in situations of alarm or distress, behavior which appears to have survival value. This is known as a discriminatory or selective attachment. Subsequently, the child begins to use the caregiver as a base of security from which to explore the environment, returning periodically to the familiar person. Attachment is not the same as love and/or affection although they are often associated. Attachment and attachment behaviors tend to develop between the ages of six months and three years. Infants become attached to adults who are sensitive and responsive in social interactions with the infant, and who remain as consistent caregivers for some time. Caregiver responses lead to the development of patterns of attachment, that in turn lead to internal working models which will guide the individual's feelings, thoughts, and expectations in later relationships. For a diagnosis of reactive attachment disorder, the child's history and atypical social behavior must suggest the absence of formation of a discriminatory or selective attachment.
Analytical psychology
One archetypal approach, sometimes called "the imaginal school" by James Hillman, was written about by him in the late 1960s and early 1970s. Its adherents, according to Samuels (1985), include Murray Stein, Rafael Lopez-Pedraza and Wolfgang Giegerich. Thomas Moore also was influenced by some of Hillman's work. Developed independently, other psychoanalysts have created strong approaches to archetypal psychology. Mythopoeticists and psychoanalysts such as Clarissa Pinkola Estés who believes that ethnic and aboriginal people are the originators of archetypal psychology and have long carried the maps for the journey of the soul in their songs, tales, dream-telling, art and rituals; Marion Woodman who proposes a feminist viewpoint regarding archetypal psychology. Some of the mythopoetic/archetypal psychology creators either imagine the Self not to be the main archetype of the collective unconscious as Jung thought, but rather assign each archetype equal value. Others, who are modern progenitors of archetypal psychology (such as Estés), think of the Self as the thing that contains and yet is suffused by all other archetypes, each giving life to the other.
