Book excerpt: Excerpt from The Time of Perception as a Measure of Differences in Sensations Whipple,2 in his study Of the discrimination of clangs and tones, took account of the relation of the speed Of judgment to certainty and correctness Of judgment as well as the relation Of speed and immediacy to correctness. The judgments fell into at most four categories as to speed, introspectively noted. The immediate judgments were found to be usually both correct and certain, while compared judgments were more Often uncertain and incorrect. Angeli,3 in a study of discrimination of shades of gray for different intervals of time, measured to tenths Of a second the time of delivering the discriminative judgment. The times were determined for the four categories of judgment, 'sure, ' 'fairly sure, ' 'like' and 'doubtful, ' for the four intervals of time 5, 15, 30 and 60 seconds. The results showed that 'like' judgments are longest, 'sure' judgments shortest, with 'fairly sure intermediate. This historical summary of the applications of the method indicates that the method has been used systematically in but two investiga tions and that these are preliminary and concerned more with the method as such than with the measurement of differences in sensa tions. The present research, it is believed, gives not only certain positive results by the method, but also a definite confirmation Of its validity and value.
