Ontogenetic features of the psychophysiological mechanisms of perception of the emotional component of speech in musically gifted children.
The cerebral mechanisms underlying musical-artistic ability were addressed by studying psychophysical measures of the perception of emotional information contained in speech in musically gifted children. Studies involved 46 schoolchildren and 48 young musicians, in three age groups: 7-10, 11-13, and 14-17 years. A test sentence was presented with three emotional intonations (joy, anger, and unemotional) via headphones; subjects' responses identifying the type of emotion were recorded. Dispersion analysis revealed age and gender characteristics in the mechanisms of recognition of emotions: thus, boy musicians led their classmates in the development of these mechanisms by 4-6 years, while girl musicians led by 1-3 years. In girls, musical training facilitated increases in the role of the left hemisphere in processing the emotional intonation of speech, while in boys, the initially marked dominance of the left hemisphere was not retained during further training.
