Purpose of reciprocity & synchrony
P: A limitation of caregiver-infant interaction explanation of attachment is that it is unclear what the purpose of reciprocity & synchrony is.
E: Feldman simply describes it as the behaviour that occurs at the same time. The concept was a phenomenon that could be reliably observed, however, it is not useful for explaining the purpose of reciprocity & synchrony.HOWEVER, there is evidence that suggests that reciprocity & synchrony are helpful in mother-infant attachment. It also found it helped the development of empathy, language and morality.
E: This suggests that reciprocity & synchrony are crucial int eh development of vital behaviours.
L: Therefore, despite the purpose of reciprocity & synchrony being unclear, they aid in both caregiver-infant interaction and the development of other important behaviour.
