title: [Diurnal changes in the effectiveness of mental activity of the operators during shift-type work].
abstract: Significant variations in the efficiency of the mental activities during the day are not detected at the shift operative work according to the average-group data. Significant differences are detected for 15% of the investigated at the level of P greater than 95%, for 45%--at the level of 80 less than P less than 95%. Significant differences within the mental activity indices under the given conditions are estimated as a decrease of adaptability of the organism.
