No “good strategy is available based on the randomness of the data. The best possible strategy based on the above transition matrices is: 1. If the subject can't distinguish between machine then press blue when blue appears, else pass. | 2. If the subject can distinguish them on Machine 1, press yellow when yellow occurs, and on Machine 2 press. blue when red occurs. For all its worth, of the existing data the following success would result - 26%, 26%, and 27%. Approved For Release 2003/04/18 : CIA-RDP96-00787R000200150011-4 15
