Motive to imitate n Learning Function - The people who are insensitive to environment’s change are not human’s ancestry. - Attraction forward novelty n Communicative Function - The people who are alone are not human’s ancestry, too. - Transfer of knowledge from one individual to another. © 2015, SNU CSE Biointelligence Lab. , http: //bi. snu. ac. kr 7

Learning Function n Attraction forward novelty “Look-at-me and do-like-me” - Observational learning. A system allow the imitation of the movement of a teacher(or model)’s movement. © 2015, SNU CSE Biointelligence Lab. , http: //bi. snu. ac. kr 8

Communicative Function n Transfer of knowledge from one individual to another. n Turn-taking :

Communicative Function n Synchrony A model of synchronization of rhythm between two systems describes the first step toward a communicative us of imitation. W A a i action perception t B action W a i action t © 2015, SNU CSE Biointelligence Lab. , http: //bi. snu. ac. kr 10
