caregiver infant interaction

• Meltzoff and moore 1977- investigated interactional synchrony and reciprocity in infants, was a controlled observation, adult showed different facial expressions (3) and childs response was observed and rated by an independent judge, an association was found between the adult and the baby suggesting interactional synchrony is innate,
• Meltzoff and moore study evaluation- positives of the study- real world contribution allowing parents to gain an understanding of caregiver infant interaction, negative- practical issues, babies are often asleep or being fed, meaning it can be hard to get reliable results due to a lack of consistency in the observations
