oor
ability, is it a good thing for you to find it out? If the teacher and
students think best, the results of all the various tests need not be
made known except to the persons concerned. The data can be used in the
various computations without the students' knowing whose measures they
are.

8. To what extent is ability a factor in life? You find people of only
ordinary ability succeeding and brilliant people failing. Why is this?

9. None of the tests so far used measures ideals or perseverance and
persistence. These are important factors in life, and there is no very
adequate measure for any of them. The students might plan some
experiments to test physical and mental persistence and endurance. The
tapping experiment, for example, might be continued for an hour and the
records kept for each minute. Then from these records a graph could be
plotted showing the course of efficiency for the hour. Mental adding or
multiplying might be kept up continuously for several hours and the
results studied as above.

10. We have said that ideals and persistence are important factors in
life. Are they inherited or acquired?

11. Do you find it to be the rule or the exception for a person standing
high in one mental function to stand high in the others also?

12. Make a complete outline of the chapter.

CHAPTER X

APPLIED PSYCHOLOGY

=The General Field.= Psychology has now reached that stage in its
development where it can be of use to humanity. It can be of use in
those fields which demand a knowledge of human nature. As indicated in
the first chapter, these fields are education, medicine, law, business,
and industry. We may add another which has been called "culture." We
cannot say that psychology is able yet to be of very great service
except to education, law, and medicine. It has been of less service to
the field of business and industry, but in the future, its contribution
here will be as great as in the other fields. While the service of
psychology in the various fields is not yet great, what it will
eventually be able to do is very clear. It is the purpose of this
chapter to indicate briefly, the nature and possibilities of this
psychological service.
