METHOD OF MICROKINETIC PSYCHOSEMANTIC DETECTION Russian patent published in 2011 - IPC A61B5/16 

FIELD: medicine.

SUBSTANCE: invention relates to field of psychology and psychophysiology and can be used in solution of various applied problems of highly specialised purpose. With exposition not longer than 40 ms, with different interval in disguised unrealised form two and more categories of semantic stimuli, which unite synonymous or close in meaning words, short phrases or images, whose subjective significance is of interest for experimenter, and one control category from semantically neutral stimuli in form of random set of digits are demonstrated. Unrealised bahavioural reactions in response to unrealised stimuli are registered with further statistical comparison of said reactions aimed at determination of subjective significance of unrealised stimuli, by means of which operator readiness is supported. Reaction to unrealised stimuli is registered in form of micromovements, superimposed on stereotypic movements of hand of tested person in response to masking stimuli. Movement is registered with discretisation from 1 to 40 mc with further programmed processing of movement image by points of beginning, finishing of movements, upper and lower peaks, intermediate peaks, change of movement direction in vertical and horizontal planes, rate and spectral composition of fluctuations in vertical and horizontal planes. In addition thesaurus of unrealised stimuli can include category of semantically neutral stimuli in form of randomly formed meaningless lines of digits, demonstrated between semantically meaningful stimuli in order to avoid effect of interference and long after-action of stimuli. Two-dimensional vector from several hundreds coordinates of points fixing unique trajectories of hand movement in response to stimulus serves as source of information about each unrealised reaction of tested person. Basing on obtained micromodulations of hand movement it is possible to compare reactions in response to stimuli, grouped in accordance with belonging to certain categories or into underthreshold stimuli, thus identifying their unique semantic groupings.

EFFECT: method makes it possible to reduce time for test carrying out and simplify procedures, as well as to examine similarities-differences of reactions in response to separately demonstrated stimuli, thus identifying their unique subjective semantic groupings, eliminating at the same time possibility of semantic influence of realised mispresentation of results by tested person.
