Interrelations between the mental work efficiency and changes in total and cerebral hemodynamics during mental activity are considered. Five subgroups of the efficiency are distinguished. Changes in the vegetative reactions considerably differ in the type as well. Basic four types of such reactions are distinguished with allowance for changes in the character of minute blood circulation volume and cerebral blood flow. Comparison of changes in the efficiency of the activity with vegetative changes shows that in the process of the mental activity the vegetative changes are determined by interrelation between the intensity of the mental activity and its efficiency. It was concluded that the higher the activity efficiency, the lower the mental intensity and changes in the total and cerebral hemodynamics and, vice versa.
研究了心理活动期间心理工作效率与全身及脑血流动力学变化之间的相互关系。区分了效率的五个亚组。自主反应的变化在类型上也有很大差异。考虑到每分心输出量和脑血流量特征的变化，区分了四种基本类型的此类反应。将活动效率的变化与自主变化进行比较表明，在心理活动过程中，自主变化由心理活动强度与其效率之间的相互关系决定。得出的结论是，活动效率越高，心理强度以及全身和脑血流动力学的变化越低，反之亦然。
