It is intriguing and challenging to learn a language by diving into the worlds of Virtual Reality (3-D environments, avatars, games) and Artificial Intelligence (chatbots, agents). What are the issues and benefits of these technological innovations? Taking readers on a journey through the brain, this book explains how VR and AI may foster and sustain connectivity between language faculties, the senses/emotions, working and long-term memory, and attention. With the speed of technological innovation increasing, cognitive demand as well as aspects of intrinsic motivation are analyzed, charted, and discussed, as these may become essential for future development of language learning experiences. This volume should be of interest to instructors, researchers, and students of languages and linguistics, cognitive psychology, and computer science.
