Imitation with Intention and Memory: an Experiment

Contents:

Author Info

  • Astrid Matthey

Abstract

Three results emerge from a simple experiment on imitation. First, I find behavior which strongly suggests an intention to imitate. Second, players im- itate successful other players rather than repeating successful actions. Third, to find imitation examples, players use several periods of memory. This lends support to learning models with a non-trivial role of memory. The experiment analyzes imitation in an individual learning context. It sup- plements the results obtained for imitation in evolutionary processes.
