Philosophical issues in AI The mind-body problem The Turing Test

The mind-body problem Recall the question “Where does the body end and the mind begin?” Where one ends and the other begins in the context of intelligence is the mind- body problem

Is the mind separate from the body? The answer depends upon which philosophical view you follow:- –Materialism, where only the material body exists and the mind does not and the brain carries out the functions of thought and intelligence –Interactionism, where the mind has a spiritual existence rather than a physical –Functionalism, where the way the mind exists is of no consequence

Philosophic Issues In 1950 Alan Turing, a British computer scientist devised a test to determine whether a computer could be called intelligent. The test was devised in response to the question “Can a computer think?”

The Turing Test The Turing Test is : –One person sits at a computer and types questions –The computer is connected to two other hidden computers –At one computer a human reads and responds to the questions –At the other a computer with no human aid runs a program to provide responses

The result If the person typing the questions can not tell the difference between the human responses and the computer responses then according to Turing the computer is said to be intelligent.
