Bowlby's attachment theory is a theory of psychopathology as well as a theo
ry of normal development. It contains clear and specific propositions regar
ding the role of early experience in developmental psychopathology, the imp
ortance of ongoing context, and the nature of the developmental process und
erlying pathology. In particular, Bowlby argued that adaptation is always t
he joint product of developmental history and current circumstances (never
either alone). Early experience does not cause later pathology in a linear
way; yet, it has special significance due to the complex, systemic, transac
tional nature of development. Prior history is part of current context, pla
ying a role in selection, engagement, and interpretation of subsequent expe
rience and in the use of available environmental supports. Finally, except
in very extreme cases, early anxious attachment is not viewed as psychopath
ology itself or as a direct cause of psychopathology but as an initiator of
pathways probabilistically associated with later pathology.
