So for the other cases.

If the individual's general preference is for muscular images, we find that the quickest time is made when attention is given to the mouth and lips.

Such is the case with Mr.B.
The general results go to show, therefore--and four cases showing no exception, added to the indications found by other writers, make a general conclusion very probable--that in the differences in reaction times, as secured by giving the attention this way or that, we have general indications of the individual's temperament, or at least of his mental preferences as set by his education.

These indications agree with those found in the cases of aphasia known as "motor," "visual," "auditory," etc., already mentioned.

The early examination of children by this method would probably be of great service in determining proper courses of treatment, subjects of study, modes of discipline, tendencies to fatigue and embarrassment, and the direction of best progress in education.
This research may be taken to illustrate the use of the reaction-time method in investigating such complex processes as attention, temperament, etc.
