[Ontogeny-specific interaction of psychophysiological mechanisms of emotional perception and educational achievement in students].

In order to explore the process of adaptation of children to school environment psychophysiological characteristics of perception of emotional speech information and school progress were experimentally studied. Forty-six schoolchildren of three age groups (7-10, 11-13, and 14-17 years old) participated in the study. In experimental session, a test sentence was presented to a subject through headphones with two emotional intonations (joy and anger) and without emotional expression. A subject had to recognize the type of emotion. His/her answers were recorded. School progress was determined by year grades in Russian, foreign language, and mathematics. Analysis of variance and linear regression analysis showed that ontogenetic features of a correlation between psychophysiological mechanisms of emotion recognition and school progress were gender- and subject-dependent. This correlation was stronger in 7-13-year-old children than in senior children. This age boundary was passed by the girls earlier than by the boys.

[Ontogenetic features of psychophysiological mechanisms of perception of speech emotional component in musically gifted children].

Cerebral mechanisms of musical abilities were explored in musically gifted children. For this purpose, psychophysiological characteristics of perception of emotional speech information were experimentally studied in samples of gifted and ordinary children. Forty six schoolchildren and forty eight musicians of three age groups (7-10, 11-13 and 14-17 years old) participated in the study. In experimental session, a test sentence was presented to a subject through headphones with two emotional intonations (joy and anger) and without emotional expression. A subject had to recognize the type of emotion. His/her answers were recorded. The analysis of variance revealed age- and gender-related features of emotional recognition: boys musicians led the schoolchildren of the same age by 4-6 years in the development of mechanisms of emotional recognition, whereas girls musicians were 1-3 years ahead. Musical education in girls induced the shift of predominant activities for emotional perception in the left hemisphere; in boys, on the contrary, initial distinct dominance of the left hemisphere was not retained in the process of further education.
