John Bowlby, after writing Maternal Care and Mental Health for the WHO, in addition to Harlow proving the existence of a certain kind of love with rhesus monkeys, other scholars also studied other directions. Among them, Mary Ainsworth, Mary Main, and Erik Hesse brought Attachment Theory.
Ainsworth designed a non-harmful Strange Situation experiment. The process involves children playing in an unfamiliar environment, during which a guardian or stranger enters the room, and then observing the child’s reaction to study the child’s attachment to the guardian. The results revealed the following four types:
Secure Attachment (B): Children will regard the guardian as a “safe base”. When the guardian leaves, the child will become uneasy until the guardian returns. And the child will only interact with strangers when the guardian is present.
Anxious-Avoidant Attachment (A): Children will avoid or ignore the guardian. Children rarely show emotional changes when faced with the guardian’s departure and return. Later studies found that the child’s heart rate still has obvious changes, but it may be because past attachment behaviors were rejected, so this can avoid rejection again. (It’s like becoming tsundere)
Anxious-Ambivalent/Resistant Attachment (C): Children will show distress before separating from the guardian, and become clingy and difficult to comfort when the guardian returns. Some researchers have found that children who have been abused in childhood are more likely to form ambivalent attachment. And as adults, they are more likely to have difficulty maintaining close relationships.
Disorganized Attachment (D): Situations that cannot be classified into A, B, or C attachment are considered D. However, the original research on psychological trauma caused by mother-infant separation was later extended to adults and became the commonly used relationship and attachment theory.
Adult Attachment (friendship, love, etc. ) has some differences from child attachment. Adult attachments are called Secure Attachment, Anxious-Preoccupied Attachment, Avoidant Attachment and Fearful-Avoidant Attachment.
Although attachment theory oversimplifies interpersonal relationships, it may still have some effect as a cheat sheet for improving communication and empathy. Psychologists also use attachment theory as the basis of Emotionally Focused Therapy to solve emotional and relationship problems between individuals, couples, or families.
