The patterns of attachment between infants and mothers have far-reaching consequences for infants’ development; infants with secure attachments fare better socially and emotionally than those with non-secure attachments (Deklyen & Greenberg,2008).
Theory suggests that differences in attachment quality result from differences in mother-child interactions: secure attachment results from a history of sensitive interactions and non-secure attachment from insensitive interaction.
Since the attachment security is held to be a product of the quality of interactions; a change in the quality of interactions should theoretically lead to a change in attachment quality. Thus, a child in a secure relationship later encountering insensitive care should tend towards a non-secure relationship, and vice versa.
