Bowlby's Monotropic Theory of Attachment

John Bowlby's monotropic theory of attachment is one of the most influential psychological theories of the 20th century. Bowlby proposed that attachment is an innate, adaptive behaviour that has evolved because it promotes survival. His theory fundamentally changed our understanding of the mother-child bond and has had enormous practical implications for childcare, adoption, and social policy.

Key Definition: Monotropy is Bowlby's concept that infants have an innate tendency to form one primary attachment that is qualitatively different from and more important than all other attachments. This primary attachment figure is the child's "safe haven" and "secure base."

The Evolutionary Basis of Attachment

Bowlby (1969) argued that attachment is an innate, biological system that has evolved through natural selection. Infants who formed close bonds with a caregiver were more likely to survive to reproductive age because they were protected from predators, fed, and kept warm. Similarly, caregivers who formed strong bonds with their infants were more likely to pass on their genes because their offspring survived.
