Perception of Virtual Reality Stimulus of Personalized and Indifferent Content Using the Oddball Paradigm

For the effective use of virtual reality in neurorehabilitation, studies of the cognitive processes of the human brain in VR conditions, in particular attention, are relevant. At the same time, an increase in the informative significance of visual stimuli, especially in a personalized virtual environment, increases the efficiency of attention, since its scenario is in the context of a person's present and past interests. Was investigation of the latency of a complex sensorimotor reaction to visually relevant stimuli of virtual reality of personalized and indifferent content. The study involved 10 healthy right-handed men aged 18–19 who signed an informed consent. According to the indicators of personalized preferences identified by the testing method, two groups of subjects were formed. The selection of subjects into two groups (5 men each) was predetermined by two VR scenarios, the content of which reflected first group or did not reflect their personal experience (personalized and indifferent environment, respectively) in second group. In the study, a comparative characteristic of the dynamics of complex sensorimotor reaction latency was studied using the experimental oddball paradigm in the conditions of virtual reality of personalized and indifferent content. It has been established that the latency of complex sensorimotor reaction to relevant visual stimuli in VR is due to its semantic content. The latency of a complex sensorimotor reaction to relevant stimuli in a personalized virtual reality is much less than in a virtual reality containing indifferent content.
