Technology has long been a helpful aid in human cognitive activities. With its growing sophistication and usage, technology is now taking a more intrinsic and active role in human cognition. The shift from an external aid to being an internal component of cognitive processing reflects a revolution in technology, cognition, and their interaction. The creation of such cognitive technologies transforms the traditional instrumental function of technology to a constitutive role that shapes and defines cognition itself. This book, which was originally published as a Special Issue of Pragmatics & Cognition (13:3, 2005), explores the new horizon of these cognitive technologies and their interactions with humans.
