According to George Miller (1956), a pioneer of the ‘cognitive revolution’ and proponent of the buzzword concept of the “magical number seven,” cognitive science in the modern sense had only started in the 1950s and gradually took shape in the mid-1970s. Based on Miller’s (2003) historical account, cognitive science as a scientific field of study was originally comprised of six core disciplines, spanning psychology, linguistics, and neuroscience, as well as anthropology, artificial intelligence, and philosophy. Over the last half century, cognitive scientists have probed into the underlying mechanisms and processes of human cognition, encompassing perception, attention, consciousness, reasoning, planning, learning, and memory, among many other topics. The six constituting disciplines have all flourished and complement each other, giving rise to a new set of interdisciplinary research agendas subsuming language acquisition and cognitive development, psycholinguistics and language processing, second language acquisition and bilingualism/multilingualism, etc.
