title: [Lateralization characteristics in the perception of speech in noise by children of different age groups].
abstract: The comparative investigation in ontogenesis of the noise immunity of child sensorial perception of two kinds of bioacoustical information (the emotional one being more evolutionary old and the semantic one being evolutionary younger) has shown that the perception effectiveness of these kinds of information depends on the noise level, the age of a child and the kind of information. The perception of semantic information is not provided with the reliable mechanisms of signal identification from noise even to the age of 16 while such mechanisms for perception of emotional information are formed in ontogenesis by the age of 14 and they are associated with the activity of the right hemisphere.
