Bowlby (1969), who first applied this idea to the infant-caregiver bond, was inspired by Lorenz's (1952) studies of imprinting in baby geese. He believed that the human baby, like the young of most animal species, is equipped with a set of built-in behaviors that helps keep the parent nearby, increasing the chances that the infant will be protected from danger. Contact with the parent also ensures that the baby will be fed, but Bowly was careful to point out that feeding is not the basis of attachment.
