LOSEV-MILLER'S MUTUAL EXCLUSION TECHNIQUE Russian patent published in 2014 - IPC A61B5/16 A61B5/205 A61B5/53 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, forensic medicine, diagnostic measurements, including in investigative practice. An interactive psychophysiological testing (PPT) involves presenting a person being tested test questions, determining, analysing the psychogenesis parameters with using the person's physical parameter sensors, indicating the results and estimating. The test questions are typed as follows: first-version questions Q1, second-version questions Q2, neutral questions N. The questions Q1 and Q2 have an alternative meaning and equal power and are characterised by an equal presentation time, a consistency of comparing the questions according to the alternative versions, a minimised subjective personal effect of the PPT test expert by sound colour and level, an unconscious emotional support on the person's question perception, as well as an identity of putting the questions to be compared, their length and a fixation of the meaningful word and/or word combination in similar segments of both questions to be compared. The test is put in accordance with a concatenation as follows X:0→C,…,C→Q1₁.Q2₁→N→ →Q2₁.Q2₂→N→…→Q1_n.Q2_n→N, wherein X is a person's identification index; 0 is a non-estimated zero question; C is a question relieving an expectation stress; Q1_i is the first-version question, wherein i=1, 2,…, n; Q2_i is the second-version question, wherein i=1, 2,…, n; N is a neutral question; n is a number of specific circumstances of the event or action; ":", "→", "." are devisors. The questions are put taking into account the staging of the tested event, including the confirmed facts or data only and excluding the expert's conjectures or versions. The results are used to state one of the two alternative versions and to estimate the respective status of the person being tested. The psychogenesis is determined and analysed with using a polygraph, while putting the questions of the two alternative versions, indicating and processing the PPT data are conducted with a computer with relevant software.

EFFECT: method provides higher information value, accuracy, reliability, objectiveness of the PPT results as compared to the previously known tests up to 90-95% with avoiding the distortion and ambivalence of the results.
