abstract="Experiments of Breitwieser and Woodrow have shown that when O does not know what the duration of an interval between a warning signal and a stimulus for reaction will be, there seems to be a narrow zone within which &quot;attention&quot; is relatively higher than for other prestimulus intervals. That is to say, the shortest reaction times occur in the interval from two to four seconds, with a leaning towards two. These findings are supported by the present experiments in which the prestimulus intervals, unknown to O, were kept approximately at one second or three seconds. A comparison ratio of the reaction times under these two intervals reveals a general tendency to favor the three-second interval: the one-second interval, arguing from the work of the previous investigators, is ahead of the most favored interval, while the three-second interval is right in the most favored zone.
