Document Summary
He wants infants to be able to behave intentionally, to show that they know the things that they know. He wants them to have the type of motor control that it is unlikely they will have, in order to demonstrate what they know. Children weren"t able to mentally represent the act, and they simply couldn"t copy the actions of the experimenter. They took babies as young as 12-21 days old, and exposed them to a model who is making some kind of a face (often a male). When the model makes the face, they looked at the face the baby made back. Babies have a good ability to stick their tongue out when you do, but they don"t often open their mouths when you do. Babies like to stick their tongues out anyways: replication issues. Can"t find any reliable imitation in babies until they"re in stage 4, about 9 months of. Deferred imitation age: collie & hayne (1999)
