Activation of Motivations, Emotions, the Law of Force and Theories of Change in Sensitivity for Personality Testing

This research was aimed to assess the severity of emotional and motivational processes during the perception of chess patterns of varying contrast and registration of visual evoked potentials (VEPs) with subsequent analysis of personal and cognitive processes on this basis. An increase in the intensity of the contrast of a reversible chess field, regardless of the emotional sphere is accompanied by an increase in the amplitude of the amplitude of the N150 wave in persons with a high degree of tension and reduced emotional stability was traced. For persons with a low degree of tension and high emotional stability in the occipital-parietal leads, an inverse relationship between the magnitude of contrast and amplitude N150 is noted. Comparison of behavioral investigation results with electrophysiological data enabled to find that the first variant of reaction was characterized by lower degree of visual images identification, under condition hampering their identification, irrespective of test objects modality.
