 First, if interrogators are allowed to draw on the results of research into, say, associative priming, then there is data that will very plausibly separate human beings from machines. For example, there is research that shows that, if humans are presented with series of strings of letters, they require less time to recognize that a string is a word (in a language that they speak) if it is preceded by a related word (in the language that they speak), rather than by an unrelated word (in the language that they speak) or a string of letters that is not a word (in the language that they speak). Provided that the interrogator has accurate data about average recognition times for subjects who speak the language in question, the interrogator can distinguish between the machine and the human simply by looking at recognition times for appropriate series of strings of letters. Or so says French. It isn’t clear to us that this is right. After all, the design of The Turing Test makes it hard to see how the interrogator will get reliable information about response times to series of strings of symbols. The point of putting the computer in a separate room and requiring communication by teletype was precisely to rule out certain irrelevant ways of identifying the computer. If these requirements don’t already rule out identification of the computer by the application of tests of associative priming, then the requirements can surely be altered to bring it about that this is the case. (Perhaps it is also worth noting that administration of the kind of test that French imagines is not ordinary conversation; nor is it something that one would expect that any but a few expert interrogators would happen upon. So, even if the circumstances of The Turing Test do not rule out the kind of procedure that French here envisages, it is not clear that The Turing Test will be impossibly hard for machines to pass.)
