Robert Abelson, 1968.
The three innovations introduced by the extended test are:
- The judges are not informed that a computer is involved in the test at all. They are told simply to compare the performance of two entrants, with respect to some dimension (e.g. womanliness or paranoid behaviour, etc).
- The computer does not participate on its own but (unbeknownst to the judges) shares time with a human subject. The two are 'switched off' periodically throughout the test.
- The judges score the human-computer pair after every question, so that separate scores can be generated for each.
