By the above table the absolute intensity of the stimulus is clearly
shown to be an important factor in determining the constant error of
judgment, since in both cases the change from _SSS_ to _WWW_ changed
the sign of the constant error, although in opposite directions. But
the effect of the relative intensity is more obscure. To discover more
readily whether the introduction of a stronger or weaker stimulation
promises a definite effect upon the estimation of the interval which
precedes or follows it, the results are so arranged in Table IX. that
reading downward in any pair shows the effect of a decrease in the
intensity of (1) the first, (2) the second, (3) the third, and (4) all
three stimulations.
