Ags observed, the sequential sampling procedure can result in 90 percent or greater reliability with psi parameters on the order of a few percent. Implementation of the sequential sampling procedure requires the transmission of a message coded in binary digits. Therefore, the target space must consist of dichotomous elements such as the white and green cards used in the experiments by Ryzl, In operation, a sequence corresponding to the target bit (0 or 1) is sent and the cumulative entries are made (Figure A-1) until a decision is reached to accept either a 1 or O as the bit being transmitted, At a prearranged time, the next sequence is begun and continues as above until the entire message has been received. A useful alternative, which relieves the percipient of the burden of being aware of his self- contradiction from trial to trial, consists of cycling through the entire message repetitively and entering each response on its associated graph until a decision has been reached on all message bits, The authors have used this technique successfully in a pilot study, but a discussion of this would take us beyond the intended scope of this paper. From the results obtained in such experiments, the channel bit rate can be ascertained for the system configuration under consideration, Furthermore, bit rates for other degrees of reliability (i.e., for other Po? Py @, and 6) can be estimated by construction of other decision 97 Approved For Release 2002/05/17 : CIA-RDP96-00787R000500020001-6
