What is the main critique of Meltzoff and Moore’s (1977) study on imitation in babies?
A
There was not much choice of behaviour for the babies to make upon observing the model’s behaviour
25
What are the 4 evidence against neonate imitation (imitation may not be as clear cut as we thought) proposed by Oostenbroek et al. (2016)?
1. Longitudinal study - 1, 3, 6,
and 9 weeks
2. Large number of alternative control model behaviours
- Matching to the model's actions was better than chance compared to some control behaviours but not others
3. Behaviour matching model more likely compared to some but not other control behaviours
4. Tongue protrusion may be
elicited by observing faces
26
When does true imitation emerge, according to Oostenbroek et al. (2016)?

28
True imitation may emerge
later (6-9 months) as
proposed by Piaget
What does this suggest about imitation in babies?
Seeing a face makes the baby want to stick their tongue out, which leads to learning, but it can’t yet be described as accurate/true imitation
29
