AbstractBowlby’s attachment theory is a theory of psychopathology as well as a theory of normal development. It containsclear and specific propositions regarding the role of early experience in developmental psychopathology, theimportance of ongoing context, and the nature of the developmental process underlying pathology. In particular,Bowlby argued that adaptation is always the joint product of developmental history and current circumstances (nevereither alone). Early experience does not cause later pathology in a linear way; yet, it has special significance due tothe complex, systemic, transactional nature of development. Prior history is part of current context, playing a role inselection, engagement, and interpretation of subsequent experience and in the use of available environmentalsupports. Finally, except in very extreme cases, early anxious attachment is not viewed as psychopathology itself oras a direct cause of psychopathology but as an initiator of pathways probabilistically associated with later pathology.
