The high unreliability of the difference (P. E. = 3.10) is noteworthy. It would seem that incidental causes have a much greater effect upon tapping ability than can be demonstrated as resulting from the removal of adenoids and tonsils. Use of the tapping test as a measure of the decrease in tendency to fatigue similarly brings out no indication of any improvement in the operative group of cases. The measure of Pg 41 fatigue was taken as a ratio; namely, the number of taps in the first, minus the number in the second half minute over the number of taps in the first half minute. Then, if there is a greater number of taps in the second, the ratio will be minus, indicating that fatigue effect is so small as to be overcome by practice effect. This was a fact in only four cases. Since what we are measuring is improvement, the ratio for test 2 is subtracted from the ratio for test 1 to find the gain in overcoming fatigue. Table VIII shows the average gain for group one to be -.0196, and the median -.045. That is, there is an average increase in fatiguability of .0196 units and a median increase of .045 with a P. E. of .02. This increase in fatiguability occurs also in the control group, average 0, and median .03 with P. E. of .03. The average gain of test group over control group is -.02 and the median gain is -.015. Again variability is relatively large, P. E. being 1.04, so that the median and average gains are -.50 P. E. and -.38 P. E. respectively. We may say, then, that...show more
