Barron, Test 2, Turing Test

In the passage, the author describes the Turing Test that determines wheter a computer is intelligent or not, and so far, no computer has passed the test. However, the speaker of the lecture casts some doubt on the correctness of Turing Test.

The speaker mainly cites an example of an scientist who holds that Turing Test has several flaws which undermine the correctness of Turing Test. In the first place, according to what the speaker says, Turing Test is based on behavior but not thought, which may induce to some kind of paradox. The example supporting this perspective is one called Chinese Room. If there are complete and elaborated references from which a computer can access, the computer will certainly reponse a good answer that can be determined as humans'. According to the speaker, the process is like this: a computer receives Chinese characters as input, then it recognize this sequence from a huge database, and at last it gives a result based on behaivior, or searching, instead of thinking. This can prove that the computer that passes Turing Test is acting intelligent rather than being intelligent. In the second place, according to the speaker, complete input plus adequate output will be enough for a computer to pass Turing Test. However, the speaker says that this doesn't mean the computer really answer basic promblems about intelligence. Finally, the speaker conculdes that Turing Test cannot determine whether a computer can, or can not think.
