Early rationality in action perception and production? A theoretical exposition.

Within recent years, the question of early rationality in action perception and production has become a topic of great interest in developmental psychology. On the one hand, studies have provided evidence for rational action perception and action imitation even in very young infants. On the other hand, scholars have recently questioned these interpretations and proposed that the ability to rationally evaluate actions is not yet in place in infancy. Others have examined the development of the ability to make rational action choices and have indicated limitations of young children's ability to act rationally. This editorial to the special issue on Early Rationality in Action Perception and Production? introduces the reader to the current debate. It elucidates the underlying theoretical assumptions that drive the debate on whether or not young children's action perception and production is rational. Finally, it summarizes the papers and their contributions to the theoretical debate.
