| Outline of Final Research Achievements |
We have studied behavioral rules or action grammars in animals by comparing structural properties of behavioral sequences among different animals, addressing computational abilities that generate complex behaviors. In particular, we demonstrated that the structure of the California Thrasher song has a small-world architecture and the Black-Headed Gross Breaks in different locations exhibit distinct clusters in their syllable-sharing structure. Furthermore, we revealed that songbirds (the Zebra finch and the Bengalese finch) and human infants do share the similar developmental constraints in a combinatorial sequential ability for vocal sequence.
