The dependence of reaction time (RT) of reproduction of presented standard intervals on their duration (100-5000 ms) was studied on 30 subjects. The intervals were limited by two electrocutaneous stimuli or two clicks and were presented both at random and at a gradual increase or decrease, with a step of 100 ms. They were reproduced by pressing a button. The RTs duration depended on the presented interval within the range from 100 to 2000 ms. Such scatter of the upper limit is due to differences in the methods of presentation of the material and to individual features of the subjects. A presence of two mechanisms of time intervals reproduction is suggested for such experimental conditions: the image of the standard interval might be created either after its presentation or in the process of its presentation. Correspondingly, the RT dependence on the interval duration is manifest in the first case and is absent in the second.
