Parent interacts with child, to which the child responds. The parent then has a still face, to which the child becomes distressed
Reciprocity
Infant and caregiver responds to the other, getting a response from them
Reciprocity phases
Alert phrases - babies signal that they are ready for interaction
Active involvement - babies and carers take an active role in initiating interactions
Interactional synchrony
Caregiver and baby reflect both the actions and emotions of the other and do this in a coordinated way.
Isabella et al - observed 30 mothers and babies together and found high levels of synchrony were associated with better attachment
Interactional synchrony research
Meltzoff and Moore
adult displayed one of three gestures
baby's response was filmed and observed
babies' gestures were more likely to mirror those of the adults than expected from chance
Strength of caregiver-infant interactions
Filmed in a lab meaning that other variables can be controlled. Also being filmed means the study can be rewatched and behaviours won't be missed. Good reliability and validity
Weakness of caregiver-infant interactions
Hard to interpret baby's behaviour as they are uncoordinated and so movements observed may not be down to caregiver or random
