Attachment theory

Attachment theory is a psychological and evolutionary framework concerning the relationships between humans, particularly the importance of early bonds between infants and their primary caregivers. Developed by psychiatrist and psychoanalyst John Bowlby (1907–90), the theory posits that infants need to form a close relationship with at least one primary caregiver to ensure their survival, and to develop healthy social and emotional functioning. Pivotal aspects of attachment theory include the observation that infants seek proximity to attachment figures, especially during stressful situations. Secure attachments are formed when caregivers are sensitive and responsive in social interactions, and consistently present, particularly between the ages of six months and two years. As children grow, they use these attachment figures as a secure base from which to explore the world and return to for comfort. The interactions with caregivers form patterns of attachment, which in turn create internal working models that influence future relationships. Separation anxiety or grief following the loss of an attachment figure is considered to be a normal and adaptive response for an attached infant. Research by developmental psychologist Mary Ainsworth in the 1960s and '70s expanded on Bowlby's work, introducing the concept of the "secure base", impact of maternal responsiveness and sensitivity to infant distress, and identified attachment patterns in infants: secure, avoidant, anxious, and disorganized attachment. In the 1980s, attachment theory was extended to adult relationships and attachment in adults, making it applicable beyond early childhood. Bowlby's theory integrated concepts from evolutionary biology, object relations theory, control systems theory, ethology, and cognitive psychology, and was fully articulated in his trilogy, Attachment and Loss (1969–82). While long criticized by academic psychologists, anthropologists and psychoanalysts, attachment theory has become a dominant approach to understanding early social development and has generated extensive research. Despite criticisms related to temperament, measurement, neglect of social complexity,...
