(4) When Tones and Active Touches were combined, the appreciation of both was raised for both F. and M. It appears (_a_) that the displacement for F. is very slight, .45+ and .23+, when compared with the displacement for M., 1.71+ and .31+. But, (_b_) that the displacement of tones is greater than that of the active touches for both F. and M. (_c_) That this same relatively great displacement of tones occurred in the opposite direction when colors and tones were combined. (5) When Tones and Passive Touches were combined, the appreciation of both was raised for F,--the tones being raised more than the passive touches. This combination was not tried with M. for lack of time. From time to time some special tests of these general tendencies were applied. From the results already set forth, one could predict that there was a strong probability that when the tone-series was combined with a constant touch-series, active or passive, the appreciation of the tones would be raised. This was tried by allowing the subject M. to rub his hand over the somewhat rough pillow of a tilting board. The results showed that the appreciation of twenty-five out of twenty-seven tones was raised. Other predictions were similarly verified. Of course, any experiment of this nature is exposed to a great many chances of error. The subjects may be fatigued, or depressed generally. But the wide range of different readings taken is a reasonable assurance that the chances of error are minimized. And it is to be noted, also, that individual differences of appreciation do not vitiate the results. In getting the "standards" no less than 2000 judgments were given by each subject, while for the tables each subject gave no less than 4000 judgments. The curves made from these data show the effect of each separate combination by their variation from the standard. The tables and analyses and conclusions already introduced show, in general, that _our appreciation of each of several stimuli in combination is different from our appreciation of the same stimuli when taken separately_. The results show that this appreciation may be either raised or lowered; that is to say, our feeling of values is not constant for a given stimulus under all conditions. From Table XIII I have found the average displacement of each series to be as follows: Tones, .90. Colors, .37. A. Touches, .28. P. Touches, .23. This shows that passive touches are subject to the least displacement, while active touches, colors, and tones are respectively subject to a greater variation. The sight-touch world is more stable than the auditory world. With M. the tones go over a full point both below and above the standard.
