METHOD FOR REMOTE COLLECTION AND GROUP TREATMENT OF PSYCHOPHYSIOLOGICAL REACTIONS WITH PRESENTATION OF VARIOUS INFORMATION Russian patent published in 2019 - IPC A61B10/00 A61B5/476 A61B5/103 G06Q30/02 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to data processing for special applications. Presenting information in text, audio, video form. Individual response to presented information is recorded by determining motor activity or EEG biopotentials. Processing of obtained data is performed based on registration of individual reactions. At the first stage, in each individual set of indicators, differences between stimuli of reference categories are calculated using the corresponding statistical criterion of differences for each of the analyzed primary indicators. Further, the obtained values reflecting the discriminating power of each primary index are subject to factor analysis separately for amplitude and time values. Values of the obtained factors are calculated. After that, respondents are combined into groups based on which of the factors has the maximum value. At the second processing step, text, audio and video stimuli are evaluated using a system of criteria obtained at the previous step. Differences between stimuli of different categories are calculated for each primary index. Further, these values and factor coefficients obtained at the first stage are used to calculate values of factors grouping primary values. For each stimulus in the space of primary features using the discriminant functions, the degree of belonging to the class of one of the reference estimates in each group formed at the first stage is calculated. Obtained classification results are weighed using the value of the factor on which the given group was constructed. Weighted classification results for each group of indicators are added.

EFFECT: method enables remote collection and group treatment of individual psychophysiological reactions of motor activity and neurophysiological indices of human brain, generate arrays of group user data, which after processing, due to their volume, enable to obtain group indices of relation to information associated with recorded reactions.
