IntroductionJohn Bowlby developed his attachment theory to examine and explore the contextual relationships between a child and his caregiver and their behavioral repercussions. According to him, it is “a way to conceptualize the propensity of human beings to create strong emotional bonds with particular others and to explain the many forms of emotional distress and personality disorder, including anxiety, anger, depression and emotional detachment, to which involuntary separation refers." and loss gives rise” (Bowlby, 1979, p. 127). A child's attachment to his or her primary caregiver establishes a sense of security, through protection, so that the child is able to explore the world confidently and without threats and risks. During the child's "sensitive period", which according to Bowlby occurs during the first nine months of life, the attachment bond should be continuous and of emotional relevance (Connors, 2011). Continuing Bowlby's research, Mary Ainsworth introduced the concept of a “secure base” and conducted research using a procedure called the “Strange Situation” to establish three models of attachment; secure attachment, insecure – avoidant and insecure – anxious – ambivalent attachment (Ainsworth, Blehar, Waters and Wall, 1978). Mary Main later added a fourth attachment dimension, insecure – disorganized (Main & Solomon, 1986). Ideally, the relationship between the child and the primary caregiver produces a secure attachment, promoting adaptability, healthy lifestyles, and positive thinking (Connors, 2011). Ainsworth, through his “Strange Situation Protocol,” identifies the securely attached child as one who is visibly upset when the caregiver leaves and happy when the caregiver returns.
