The system allows analyzing the processes of perception and evaluation of emotionally significant information based on the registration of indicators of hand micromovements. Special organization of research and methods of processing provide obtaining objective data and their psychological interpretation within various conceptual models (motivation analysis, relationship analysis, life style analysis, etc.).
The methodological basis of the system is represented by the method of Associated ideomotor response, implemented on the following principles:
1. Special organization of research, built as a sequence of elementary actions.
2. At each stage of information processing and formation of the motor program of elementary action micro-movements of hands are registered.
3. Spatial trajectories of movements are compared with the stages of action formation and by means of machine learning methods serve for analysis of information processing process at each stage.
Obtained indices characterize the process of information evaluation in the following directions: Perceptual level
(primary perception) - at this level of perception, perceptual systems evaluate physical (brightness, color, etc.) and primary biological characteristics of information (acceptance, rejection, etc.). Association level
(perception) - at this level the information is assessed from the point of view of cognitive schemes, both individual and social (motivation, attitudes, beliefs, etc.). Cognitive assessment
. Stage of brain processing of information from a rational point of view (logical organization of material, utilitarian use, practical significance, etc.). Emotional evaluation.
Evaluation of information according to emotional experience (for example, aesthetic evaluation of information, degree of similarity with emotional objects or situations, emotional significance). Assertiveness.
Indicator of subjective certainty in assessment of information, degree of subjective fluctuations in assessment. to the list of projects
