Estimation of time intervals in an array of intervals. I.

It has been shown that when man estimates the duration of separate brief time intervals(300-1,000ms), elements of a certain array of time intervals within the same range, the estimation is not affected by changes in the other elements of the array. The complex light and dark intervals are considerably underestimated. The separate estimation of two elements (light and dark interval) from the array has shown that the sum of the separate responses exceeds the estimation when the same two elements have to be estimated together as a total interval. The results could be explained by the existence of at least two "internal clocks".

Mechanisms of correction in a "hit the target" task experiment.

The ability of men to change their behaviors depending on previous errors is studied. It is found that in a task involving pressing of a key simultaneously with the second of two consecutive light signals with a constant intersimulus interval (800 ms), the subjects altered their responses alteration depending on the preceding error. Using the same task but with variable intersignal interval (750, 800 and 850 ms) and provided the subjects did not understand that in fact three different intervals were presented to them, it was found that the same corrections were made as in the task with constant interval. The different subjects accepted the task differently and therefore their mean response times and the slope of the regression line are different.
