of persons in many ways. Here is a test which deals with the range of attention. If you desire to discover the capacity of any person to pay attention to unfamiliar questions or subjects which might at some future time have great importance, try this test. Have a piece of pasteboard cut into squares, circles, triangles, halfmoons, stars and other forms. Then write upon each piece some

such word as hat, coat, ball or bat. The objects are then placed under a cloth cover and the subject to be examined is told to concentrate his attention on the shapes alone, paying no attention to the words. The cloth is lifted for five seconds and then replaced. The subject is then told to draw with a pencil the different shapes and such words as he may chance to remember. The experiment should then be repeated, with the injunction to pay no attention to the shapes but to remember as many words as possible, and write them down on such forms as he may happen to recall.

Of course, the real object is to determine whether the subject will see more than he is told, or whether he is a mere automaton. The result will tell whether his

attention is of the narrow or broad type. If it be narrow, he will see only the forms in the first case and no words, and in the second case he will remember the words but be unable to recall the shape of the pieces of cardboard.

His breadth of attention will be shown by the number of correct forms and words combined which he is able to remember in both cases. In other words, this will measure his ability to pay attention to more than one thing at a time.

Other things being equal, the narrow type of attention belongs to a man fitted for work as a bookkeeper or mechanic, while the broad type of attention fits one for work as a foreman or superintendent or, lacking executive ability, for

work requiring the supervision of mechanical operations widely separated in space.

The ordinary man sees but one thing at a time, while the exceptional man sees many things at every glance and is prepared to remember and act upon them in emergency.

Having determined a person's scope of attention, you may want to test his accuracy in details as compared with other men. To conduct such an experiment dictate a statement which will form one typewritten letterhead sheet. This statement should comprise facts and figures about your business of which the subjects to be tested are supposed to have accurate knowledge. After this original page is written, have your

typist write out another set of sheets in which there are a large number of errors both in spelling and figures. Then have each of the persons to be examined go through one of these sheets and cross out all the wrong letters or figures. Time this operation. The man who does it in the quickest time and overlooks the fewest errors, naturally ranks highest in speed and accuracy of work.
