The article presents data on the impact of inter-hemispheric functional asymmetry on the speed and number of errors in young healthy test person (320 human) in conditions of emotional stress. Righthanded subjects with type «Artist» of higher nervous activity (HNA) made fewer false identifications upon imagespresentation in the right of computer screen: 1,0±0,2% - for errors such as «omissions» and 6,0±0,6% - for errors such as «false alarms.» In right-handed subjects with type «The Thinker» of HNA observed significant differences in the rate of identification to object to the left of the screen (431±7 ms). Reaction time and number of errors were not significantly different in subjects handers and retrainedleft-handers when display images on both the left and right of the monitor screen. The results suggest that students withleading right hand and the type «Artist» of HNA more susceptible to examination stress.

Keywords: functional asymmetry , fragmented images, voluntary attention, sensorimotor time.
