| Outline of Final Research Achievements |
To understand the mechanisms for realtime sensory-motor synchronization, this study focused on the capability for vocal learning of budgerigars and Bengalese finches. Budgerigars have larger plasticity for vocal learning than Bengalese finches, so that we could expect that budgerigars show better performance in synchronization for rhythmic sounds, if we follow the "vocal learning and rhythmic synchronization hypothesis". The birds were trained to generate a series of key-pecking in response to a metronomic stimulus using an operant conditioning technique. The results revealed the Bengalese finches had a lesser performance than budgerigars; however, even in budgerigars, the performance were quite different from that of humans. Therefore, the study indicated further studies considering other factors in addition to vocal learning will be necessary to see the evolution and the mechanisms of the capability for rhythmic synchronization in perspective.
