Perhaps the most influential explanation of attachment was presented by John Bowlby who began developing his ideas in the 1940s. Bowlby presented two key theories, namely the maternal deprivation hypothesis and his theory of attachment, which we shall consider here. The ideas behind these theories are closely linked.
