Abstract

The development of objective methods for assessing emotional perception is important for cross-cultural research and linguistic technologies. The obtained data find practical applica­tion in clinical psychology and in the study of multilingual consciousness. The aim of the study is to identify stimuli that elicit the maximum emotional load of perception in multilin­gual individuals, based on an objective analysis of their recorded neurophysiological (EEG) and autonomic (ECG and GSR) responses. The participants of the experiment were 54 se­cond-year medical students aged 18—23 enrolled in the “General Medicine” program from India, who are proficient in Hindi dialects, Russian, English, Ancient Greek, and Latin. The study was conducted through the presentation of stimuli belonging to different semiotic sys­tems to multilingual participants, using the software system “Egoscop,” which recorded EEG, ECG, and GSR data during stimulus presentation, after which a mathematical analysis was performed to identify those stimuli that induced the highest percentage of arousal (emo­tionality) as a response to the stimuli. The highest physiological responses in multilingual participants were elicited by photographs and sentences in English, which was manifested in increased EEG, GSR, and ECG activity. The stimuli were selected from familiar educational materials using the principle of familiarity and belonged to different semiotic systems, which ensured their recognizability, determined the level of arousal, and made it possible to use them as triggers for the activation of previously learned concepts. Thus, for the first time, objective multimodal data were obtained using EEG, ECG, and GSR markers with the application of the “Egoscop” software system, revealing neurophysiological and autonomic correlates (markers) of the emotional complexity of processing the presented stimuli in multilingual individuals.
