Abstract

Temporal Fusion.—We have seen that, during and after its application, a stimulus evokes a whole series of changes in consciousness. The interval between the two sounds appears to have the specific character of "moderate" or "adequate" length; and the entire series of events—sound, interval and sound—lies within what has been called the "specious" or "sensory" present. This is so, because a sound needs about 550σ for the development of its complete effect on consciousness. When a second sound follows after the lapse of this interval, the whole series of events is combined and apprehended as a present whole with a maximal degree of ease and agreeableness. If, on the other hand, the second sound occur somewhat sooner, the complete development of the effect of the first sound is interrupted, and the interval, instead of appearing "moderate" or "adequate," is now adjudged absolutely "short." Correspondingly, intervals which are longer than the "adequate" interval are termed absolutely "long." The Effect of Varying the Stimulus.—When a still shorter time interval, less than 400σ is allowed to elapse between two like stimuli, its apparent length depends upon the nature of those stimuli. Filled and Empty Intervals.—The apparent length of the interval elapsing between two stimuli is influenced by the number and the nature of experiences occurring during that interval. When two equal intervals are compared by a subject, who is idle during the first but occupied in reading aloud during the second interval, the latter almost invariably appears to be shorter than the former, whatever be the order in which the two intervals are given.
