ABSTRACT
This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book provides a history of augmentation of cognitive functions using technological devices. McLuhan refined the conceptualization of technology by observing that technologies were increasingly extending cognitive function. The book proposes a framework for assistive technology for cognition (ATC) based on the mental functions. It shows how these specific cognitive abilities can be selectively augmented by ATC. The book uses the International Classification of Function (ICF) as the classification of cognition and function. The structure of the ICF allows us to indicate the cognitive functions that have sufficient clinical evidence to inform those prescribing or using technology. Human culture has refined the neuro-socio-technical loop, producing a technical environment to support cognition and social practices that support cognition. That technical environment now includes portable electronic devices which can closely emulate brain functions.
