We have here twenty comparisons each of movements away from the original positions and movements back to the original positions:
In the first case, 15 took less time under I., 5 took more time under I.
The 5 cases of more time occurred with two subjects (H., 3 and I., 2).
In the second case, 12 took less time under I., 8 took more time under I.
The 8 cases of more time occurred with three subjects (G., 1; H., 3; I., 4).
If we omit H.'s record and take the general averages for each subject, we find the following advantages in time in form of movements where the object had been moved;
| B., | 0.59 | seconds. |
| G., | 0.52 | " |
| K., | 1.84 | " |
But I., 0.35 seconds in favor of movements when the object had not been moved.
Combining these results, we have 0.74 sec. as the average gain in time for these four subjects.
