+ Supporting evidence for interactional synchrony
Meltzoff and Moore found an association between the expression or gesture the adult had displayed and the actions of the baby.
An adult model displayed 1 of 3 facial expressions or hand movements where the fingers moved in a sequence.
When the infant's dummy was removed, the child's expression was filmed.
Each observer scored the tapes twice so intra-observer and inter-observer reliability could be tested. All scores were greater than 0.92.
Infants as young as 2-3 weeks old imitated facial and hand gestures.
- Problems with testing infant behaviour: Infants mouths are constantly moving and the expressions that were tested occur frequently. This makes it difficult to distinguish between general activity and specific imitation.
