Not illustrated. 1908 edition. Excerpt: ...agrees with Table 41 although the observed values are somewhat larger than we may expect on the basis of the numbers of this table. The results of the final determination of the just imperceptible positive difference compare in this way with those for the just perceptible positive difference. A striking feature of this comparison is the sign of the differences. The just perceptible positive difference is almost invariably larger than the just imperceptible positive difference. This observation agrees with the results of previous investigators of the method of just perceptible differences, who as a rule attributed this fact to the particular order in which the comparison stimuli were presented. It was supposed that a small stimulus was more readily perceived, if it was preceded by several other small stimuli of decreasing intensity, because attention was better adapted by the preceding stimulation. This explanation can not hold for our experiments because the stimuli were presented in very different order and an adaptation of attention, therefore, cannot take place. We now turn to the description of our observations on the just perceptible and on the just imperceptible negative difference. The empirical determinations of the probabilities of a "lighter"judgment are the data which we need for this computation. These numbers are given in Table 53 (Appendix p. 198) for each subject in one double column. The numbers in the columns marked "1" give the probabilities of "lighter"-judgments for the various differences. The numbers in the columns marked "not-1" give the probabilities of judgments which are not "lighter"-judgments. These probabilities are of course equal to the differences of the...
