FIELD: medicine.
SUBSTANCE: invention refers to medicine, particularly to general psychiatry and sexology, namely to forensic psychiatric examination. Patient is exposed to a series of visual erotic stimuli within a single-format visual test aimed at detecting paedophilic disorders or disorders of an aggressive-sadistic circle. Evaluating the tentative research eye behaviour and activation of the sympathetic nervous system by recording four physiological processes: saccade activity, fixation activity, blinking and pupil diameter changes. That is followed by expert analysis of the obtained data by viewing a video recording of saccades for evaluating the visual perception of the stimulus material. Thereafter, the statistical differences of the physiological responses obtained by presenting a standard and deviant paedophilic or sadistic stimulus are compared by using parametric and nonparametric methods of statistical analysis. Then, for the released stimulus, at least 5 significant parameters are selected, which are normalized and logistic regression analysis of normalized values is performed. At the same time those reactions are considered to be statistically significant, the probability of which is equal to or exceeds 0.95.
EFFECT: method provides more accurate diagnosis of paraphilic disorders.
