Human ancestors first modified stones into tools 2.6 million years ago, initiating a cascading increase in technological complexity that continues today. A parallel trend of brain expansion during the Paleolithic has motivated over 100 years of theorizing linking stone toolmaking and human brain evolution, but empirical support remains limited. Our study provides the first direct experimental evidence...
If humanoid robots are to become commonplace in our society, it is important to understand how they are perceived by humans. An influent model in social cognitive neuroscience posits that in human face-to-face interaction, the observation of another individual performing an action facilitates the execution of a similar action, and interferes with the execution of different action. In one interference...
Imitation is a vast topic for both human sciences and robotics. Recent advances in the understanding of the neural mechanisms of imitation offer methodologies that bring the two research domains closer. In this paper we analyze how an imitation system can be bootstrapped from a non-imitative system at an abstract level so that the ideas derived can be applicable to infant development as well as robotics...
Imitation is a natural mechanism involving perception–action coupling which plays a central role in the development of understanding that other people, like the self, are mental agents. PET was used to examine the hemodynamic changes occurring in a reciprocal imitation paradigm. Eighteen subjects (a) imitated the actions of the experimenter, (b) had their actions imitated by the experimenter, (c)...
