Document Summary

We have a long progression of object permanence development, in piaget"s view. Underestimation: piaget, argument that he is wrong about that because imitation is good far sooner than piaget thought; even deferred imitation and object permanence is good far sooner than he though. Imitation: piaget thought they didn"t" do it well till 12-18 months, meltzoff & moore (1977) Expt: had a model sit across the baby (12-21 days) and the model either did tongue protrusion, mouth opening or lip purse. The baby was watched by an observer who didn"t know what the model did. Results: ~40% of the time the baby did the tongue protrusion when the model did it (they did a mouth opening ~10% of the time). But when the model did a mouth opening the baby was only 8% as likely to imitate them (and did a tongue protrusion ~2%) graph. There were replication issues at this age to 9 months.
