SCHAFFER AND EMERSON STUDY
60 babies most from working class families were visited at home every month for a year and 18months
seperation anxiety was measured by asking mothers about Childs behaviour during everyday separations (eg; Adult leaving the room)
stranger anxiety was measured by asking mums questions about their Childs anxiety response to unfamiliar adults
50% of babies showed seperation anxiety towards particular adult (25-32weeks of age)
specific primary attachment- usually with mother
attachment- likely towards caregiver who was most sensitive to infants signals/facial expressions (reciprocity), this wasn't who the infant spent the most time with
strengths- has high external validity, babies behaviour is unlikely to be changed by the precedes of observers and participants behaved naturally when being observed
limitations- problem with how multiple attachment is assessed, doesn't show behaviour towards secondary figures (playmates)
- timing of multiple attachments is conflicting, these cultures are called collectivists as families work together in everything
