Turing's Test and Conscious Thought

Over 40 years ago, A. M. Turing proposed a test for intelligence in machines. Based as it is, solely on an examinee's verbal responses, the Test misses some important components of human thinking. To bring these manifestations within its scope, the Turing Test would require substantial extension. Advances in the application of AI methods in the design of improved human-computer interfaces are now focusing attention on machine models of thought and knowledge from the altered standpoint of practical utility.
