METHOD FOR ASSESSING INFORMATION PERCEPTION Russian patent published in 2014 - IPC A61B5/16 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to carrying out psychophysiological studies, e.g. analysing the individual's psychophysiological responses, and can be used in medical purposes, advertising industry, functional diagnostics, education science, psychology, judicial practice and criminal science. Current normal baseline physiological parameters of a person being tested are recorded by means of a polygraph. That is followed by forming a number of independent conceptual blocks of visual information to be presented to the person being tested on a demonstration monitor of an eye motion recording device to assess the subjective significance of the visual information. An eye position, motion, a path of motion and fixation lengths are recorded; zones of preferential passive concentration fixation are recorded. The derived data are analysed to select a primary gaze zone and to determine a gaze length. Visual information elements drawing much attention are determined; when presenting the visual information by means of the eye motion recording device, synchronous measurements of the physiological parameters of the person being tested are taken by using blood pressure contact sensors, photoplethysmographic measurement, galvanic skin response, upper and lower respiration pressure transducers, tremor sensors connected in turn to a sensor unit of a polygraph recording and processing the signals supplied from the sensors. The physiological parameter variations of the person being tested are assessed by comparing an excursion of their current values from the pre-recorded baseline values; the physiological parameter variations of the person being tested specific for perceiving the subjectively significant information and being simultaneous with the primary gaze moments are used to detect the visual information elements having the most emotional impact on the person being tested. Thereafter, the qualitative emotional assessment is ensured by distributing the detected visual information elements according to the pre-set parameters into a sequence with opposite coordinates in the form of verbal antonyms with using a semantic differential method.

EFFECT: method enables providing more accurate psychophysiological studies related to assessing the information perception, assessing the exposure of the visual information and its significance for the individual by recording the physiological parameters and using the semantic differential method.
