Schaffer and Emerson; studied 60 babies, every 4 weeks, first year and at 18 mths
Mothers asked about protests in seperation situations
Babies attached to people not involved in physical care
39% mother not main attachment figure
Feeding not the primary explanation for attachment
Does not support learning theory
Problems; Biased, mothers may lie about behaviour
Cant generalise
