    Abstract:
    In the study carried out on children aged 10 years (51 persons), subjects aged 16-17 (11) and adults (19) characteristics of the perception and attention interaction were studied by means of electrophysiological parameters analysis (ERP, CNV, EEG) of the process of solution of various visual tasks. It has been shown that adequate brain provision of this process is based in adults both on the functional topographic differentiation and specialization of separate perceptive operations and on the possibility of controlling generalized and local activating influences according to task requirements. In children aged 10, not differing from the adults by the success of the perceptive activity, age peculiarities of its strategy are revealed connected with functional brain organization. Basic distinctive features of children perceptive activity are intensified regional specificity manifested both in responses to relevant and non-relevant stimuli, and excessive generalized activation testifying to incomplete structural-functional maturation of the frontal regions of the cerebral cortex. Increasing functional activity of these structures in ontogenesis provides for the selectivity of perceptive, cognitive and activating processes, adequate to the requirements of the task.
