Can the Turing Test Help Us to Understand Human Mental Funct

The study of artificial intelligence has been of particular interest to psychologists for many years. Not only can an intelligent machine be used to complete tasks that could normally only be done by humans, machined can test ideas about the functions of human intelligence. An article by Turing (1950) described a way of answering the important question ‘Can machines think?’. This idea is called ‘The Turing Test’ and is based on The Imitation Game.

Turing’s main statement in this article is that the functions of the human brain must be computable. He puts forward ideas about how machine intelligence can be achieved.

The Imitation Game involves three people: a man, a woman and an interrogator who can be of either sex. The interrogator is in a different room to the man and woman and asks them questions by teletype in order to try and determine which one is the woman. The man tries to pretend that he is the woman and the woman has to convince the interrogator that it is actually she. If the man is successful in pretending to be the woman, we would expect that the interrogator would decide correctly on no more than 50% of trials. Turing developed this imitation game and suggested it be conducted with a machine to re


Hayes & Ford (1995 [6]) argue that the Turing Test should be abandoned. They believe that time could be better spent on other areas of cognition than building a machine which could pass the Turing Test. They argue that a machine such as this cannot help us to understand human mental functioning and is unnecessary when there is enough real human cognition.

1. There is one limitation for computers, which does not apply for humans. Godel’s Incompleteness Theorem states that there are truths that humans can recognise but not prove. Even when ideas are proven, it is always possible to create new statements that cannot be proven. This becomes an obstacle to artificial intelligence. A computer would not be able to recognise these truths because it would have to prove them. This idea was developed by Lucas (1961 [6]) who argued that it is impossible to produce a system that can do everything a human mind can do. A machine can never be complete.
