Artificial inteligence

AI Overlaps with several other disciplines
If we construe AI in this way (as studying how information is acquired, processed, stored, used, etc. in intelligent animals and machines) then it obviously overlaps with several older disciplines, including, for instance, psychology, neuroscience, philosophy, logic, and linguistics. What is new in AI is that the development of computers has given us new ways of investigating the problems. Previously psychologists and brain scientists could only observe and do experiments on existing information processing systems, such as human beings and other animals; and philosophers could only theorise in the abstract about how mind and language ought to work. Now, however, we can go beyond those methods and also "play God", that is we can design new kinds of working systems to demonstrate the implications of our theories and check out whether they can explain the facts they are intended to explain.
