A method for determining the level of anxiety in school-age children comprises the automated provision of pairs of acoustic signals (warning and imperative), pressing the button in response to the imperative signal with simultaneous discharge of bioelectrical activity, and pairs of acoustic signals are provided with different pitch (high-high, high-low, low-low, low-high), children press the button in response to pairs of signals of the same tone while recording bioelectric activity of the brain in 16 standard leads in accordance with the "10-20", with measuring the amplitude and latent periods of components caused by electroencephalographic potentials and children without intensity of amplitudes of components N1, P1, N2, P2, P300 are selected, and also having small values of the latent periods of complex wave P1-N1-P2, indicating that elevated levels of anxiety. |
