Arthur Reber is best known for his work on implicit learning, the process whereby useful and useable knowledge is acquired independent of awareness of either the process or the products of learning. He first demonstrated the phenomenon in 1967 and followed up on it in dozens of papers and books. The theory he developed, based on general principles in evolutionary biology, predicted that implicit cognitive functions would be robust in the face of neurological and psychological disorders, be fully functional at birth, maintain the mechanisms throughout the life span, show far less individual variation than explicit processes, and show continuity across species. Lately he's used the evolutionary biology approach to explore the emergence of consciousness and concluded that it is coterminous with life itself. He holds a courtesy appointment in the Psychology Department at the University of British Columbia. Website.
