Why is the Turing test conducted through typed text alone?

Text-only conversation stops the judge being influenced by a machine's voice or appearance, so the machine is judged only on the content of what it says.

State the role of the human participant in the Turing test.

The human participant converses with the judge alongside the machine. The judge therefore has a genuine human standard to compare against instead of deciding in isolation.

Give one criticism of the Turing test as a measure of intelligence.

A machine can pass the Turing test by imitating conversation convincingly without understanding a word of it, so the test measures the appearance of intelligence rather than intelligence itself.

Questions from this subtopic

Each one with the model answer underneath.

1
What is the Turing test?
Model answer
The Turing test is a practical test in which a judge holds typed conversations with a hidden person and a hidden machine. The machine passes if the judge cannot reliably tell which is which.
2
Who proposed the Turing test, and in what year?
Model answer
Alan Turing proposed the test in a paper published in 1950, where he set it out as an imitation game.
3
Explain the significance of the Turing test in defining artificial intelligence.
Model answer
The Turing test replaced the unanswerable question of whether a machine can think with an observable behavioural test, so intelligence is judged by whether a machine's responses are indistinguishable from a person's rather than by what happens inside it.
4
Why is the Turing test conducted through typed text alone?
Model answer
Text-only conversation stops the judge being influenced by a machine's voice or appearance, so the machine is judged only on the content of what it says.
5

Model answer

6
