attachment theory

attachment theory

a theory that (a) postulates an evolutionarily advantageous need, especially in primates, to form close emotional bonds with significant others: specifically, a need for the young to maintain close proximity to and form bonds with their caregivers; and (b) characterizes the different types of relationships between human infants and caregivers. These relationships have been shown to affect the individual’s later emotional development and emotional stability. See also insecure attachment; secure attachment; Strange Situation. [originally developed by John Bowlby and later expanded by Mary D. Salter Ainsworth]
