TACTUAL TIME ESTIMATION.

BY KNIGHT DUNLAP.


I. GENERAL NATURE OF THE WORK.


The experiments comprised in this investigation were made during the
year 1900-1901 and the early part of the year 1901-1902. They were
planned as the beginning of an attempt at the analysis of the
estimation of time intervals defined by tactual stimulations. The only
published work in this quarter of the field so far is that of
Vierordt,[1] who investigated only the constant error of time
judgment, using both auditory and tactual stimulations, and that of
Meumann,[2] who in his last published contribution to the literature
of the time sense gives the results of his experiments with 'filled'
and 'empty' tactual intervals. The stimuli employed by Meumann were,
however, not purely tactual, but electrical.
