Three and 4-year olds encode modelled actions in two way leading to immediate imitation and delayed emulation.

Abstract

When copying a model's behavior with a tool, children tend to imitate (copy the specific actions to replicate the model's goal) rather than emulate (bring about the model's goal in the most efficient way). Tasks producing these findings test children immediately after the behavior is modeled. In 2 experiments, we investigated children's copying behavior after a delay (of a week). In Experiment 1 (n = 90), we found that although 3- and 4-year-olds often imitate in the short term, they are more likely to emulate in the long term. Data from Experiment 2 (n = 80) were consistent with children remembering actions that were relevant to a causal narrative of the task. Overall, our data suggest that children simultaneously encode modeled behavior in 2 ways that lead to both imitation and emulation. In the discussion, we consider what kind of information leads children to emulate in the long term
