The evolutionary roots of human imitation, action understanding and symbols
This paper focuses on how human complex imitation and its developmental processes are related to the abilities for action
representation, acquisition of symbols, and language. After overviewing the characteristics of imitation in chimpanzees and
humans, I propose a model of imitation emphasizing how these two species differ in the ways they process visual-motor
information. These differences may in turn contribute to core interspecies differences in higher-order cognitive functions,
not only for bodily imitation but for action understanding through complex referential information from faces, sharing
symbols, and language. This ‘developmental-comparative’ approach reveals the development of species-specific intelligences,
and shows what is shared and not shared between humans and other primates. In doing so, we can obtain a more complete
understanding of the emergence of the ‘language-ready brain’ in relation to its biological and evolutionary foundations.
