This free course, Attachment in the early years, covers theory and research in the area of attachment in early childhood. In the 1950s, John Bowlby was the first person to develop a theory about the significance of early attachments between caregivers and very young children. His work has stimulated a massive and very productive field of research with important implications for childcare. This OpenLearn course describes Bowlby's theory and the work that has built on it, illustrated with video recordings of the assessment of attachment in a laboratory setting and a talk by an eminent attachment researcher.
