attachment - caregiver - infant interactions

• Reciprocity


  This develops by about three months. The interaction is reciprocal, when each person responds to the other's signal.
• Feldman (2012) points out that synchrony and reciprocity simply describes behaviour, but they do not tell us the developmental purpose of them.
• Validity of observations


  • Well controlled and filmed from multiple angles, enabling inter-rater reliability as more than one observer can watch
  • Babies don't know they are being observed and so do not change their behaviour
