[PHYSIOLOGICAL TREMOR INSTANTANEOUS FREQUENCY DYNAMICS UNDER VARIOUS EMOTIONALY LOADED STIMULATION]

Emotionally evoked physiological tremor dynamics was investigated on varying stimulus efficiency. Experimental protocol includes randomized presentation of four variant visual stimuli, one of the followed - subject’s second name, random shuffled letters of second name, graphic representation of simple arithmetic expression with correct or incorrect answer. The physiological tremor acquisition was implemented by 3-axial digital accelerometers, fixed on external side of index fingers. The data analysis explained unconscious psychomotor activity dynamics under emotional status transitions. Evoked reactions specificity gives an opportunity to suppose stimulus-dependent lateralization of unconscious motor responses. Valid differences of the right hand psychomotor reactions were achieved for the most emotionally loaded stimulus - second name.
