- some mothers may be unable to abstain from the workplace for a long period after giving birth due to extenuating circumstances (eg: financial problems)
- this means that they cannot develop a high level of interactional synchrony with their infant
- yr1, data collected through monthlyobservations + interviews, with a follow-up visit every 18 months
- stranger anxiety (signs of discomfort when left with researcher) and separation anxiety (signs of discomfort when primary caregiver moved to another room) were assessed
- separation anxiety occurred most in babies by 25-32 weeks, stranger anxiety occurring in most a month later
- 18 month follow-up, 87% developed multiple attachments, however strongest was to mothers with consistent caregiver-infant interactions
- suggest development occurs in stages outlined by Schaffer (biologically influenced?), multiple attachments develop quickly - not just primary attachment to the mother as argued by Bowlby
- quality of caregiver-infant interaction directly impacts the strength of the attachment
- research suggests that fathers' take on a more challenging/playful role for the infant, which is just as important
- socially sensitive: research argues the role of the mothercannot be replaced by the role of the father, may lead to single/doublefather families feeling as though they cannotfully provide for their infants
- economic implications: research could lead to legislation ensuring equalmaternity and paternity leave
