(5) The session reliability is determined by computing the number of correctly perceived target elements divided by the total number of elements that constituted the response. (6) The result of Step 2 is compared against all other targets in the pool to provide a quantitative assess~ ment of the RV session. Steps 2 through 6 are all done by computer. Finally, for a given remote viewer, progress reports and graphs for accuracy, reliability, and sta- tistical measures are continually updated. These three measures provide an overall assessment of a remote viewer's training record. F. (U) Analysis of Response to Unknown Targets (U) The analysis of RV responses to a priori unknown targets can be accomplished with a modification of the above procedure. (1) A target pool is constructed from sites that are representative of the class of targets under investi- gation. As above, an appropriate descriptor list is generated from these targets. (2) The RV response is scored with regard to the descriptor list from Step 1. (3) The target from Step 1 that has the highest score resulting from the computerized matching is selected as the one most similar to the one under investigation. (4) With the use of database management, accuracy! records are maintained on a descriptor-by-descriptor basis. (Of course, the accuracy can only be determined from actual knowledge of the site as information becomes available.) (5) As individual accuracy assessments accumulate for a specific remote viewer, they can be used to assign a priori probabilities that individual target elements identified by the viewer are likely to be at a site in question. 50 UNCLASSIFIED Approved For Release 2002/05/17 : CIA-RDP96-00788R001800210001-0 eT
