The comparison gives results which at first appear quite irregular. These are shown in Table VII. below, where the headings (1)--(3), etc., indicate the classes compared, and in the lines beneath them '+' indicates that the interval under consideration is estimated as relatively greater (more overestimated or less underestimated) in the second of the two classes than in the first,--indicating the opposite effect. Results for the first interval are given in the line denoted 'first,' and for the second interval in the line denoted 'second.' Thus, the plus sign under (1)--(3) in the first line for subject _P_ indicates that the variation _RLL_ caused the first interval to be overestimated to a greater extent than did the variation 133. TABLE VII. SUBJECT _P._ SUBJECT _W._ SUBJECT _B._ SUBJECT _Hy._ (1)--(3) (3)--(4) (1)--(3) (3)--(5) (2)--(1) (6)--(2) (2)--(1) First. + - + - - + - Sec. + + - + + + + The comparisons of (6) and (2), and (1) and (3) confirm the provisional deduction from Table IV., that the introduction of a _local change_ in an interval _lengthens_ it subjectively, but the comparisons of (3) and (5), (3) and (4), and (2) and (1) show apparently that while the _amount_ of the local change influences the lengthening of the interval, it does not vary directly with this latter in all cases, but inversely in the first interval and directly in the second. This is in itself sufficient to demonstrate that the chief factors of the influence of locality-change upon the time interval are connected with the spatial localization of the areas stimulated, but a further consideration strengthens the conclusion and disposes of the apparent anomaly. It will be noticed that in general the decrease in the comparative length of the first interval produced by increasing the spatial change is less than the increase in the comparative length of the second interval produced by a corresponding change. In other words, the disparity between the results for the two types of test is greater, the greater the spatial distance introduced.
