Developmental importance- LIMITATION
Simply observing a behaviour does not tell us its developmental importance.
Ruth Feldman (2012), points out that ideas like synchrony simply give names to patterns of observable caregiver and baby behaviours. They can be reliable to observe but not useful in understanding child development as it does not tell us the purpose of these behaviours.
This means we cannot be certain from observational research alone that reciprocity and synchrony are important for a child’s development.
