derstand and see only darkly or not at all.
Literature and art, and all other creations and products of man take on
a wholly new interest to the psychologist.

SUMMARY. Psychology is of service to education in ascertaining the
nature of the child and the laws of learning; to law, in determining
the reliability of evidence and in the prevention of crime; to
medicine, in the work of diagnosis and treatment; to business, in
advertising and salesmanship; to the industries, in finding the man
for the place and the place for the man; to everybody, in giving a
keener insight into, and understanding of, human nature.

CLASS EXERCISES

1. Visit a court room when a trial is in progress. Note wherein
psychology could be of service to the jury, to the judge, and to the
attorneys.

2. To test the reliability of evidence, proceed as follows: Take a large
picture, preferably one in color and having many details; hold it before
the class in a good light where all can see it. Let them look at it for
ten or fifteen seconds, the time depending on the complexity of the
picture. The students should then write down what they saw in the
picture, underscoring all the points to which they would be willing to
make oath. Then the students should answer a list of questions prepared
by the teacher, on various points in the picture. Some of these
questions should be suggestive, such as, "What color is the dog?"
supposing no dog to be in the picture. The papers giving the first
written description should be graded on the number of items reported and
on their accuracy. The answers to the questions should be graded on
their accuracy. How do girls compare with boys in the various aspects of
the report? What is the accuracy of the underlined points?

3. Let the teacher, with the help of two or three students, perform
before the class some act or series of acts, with some conversation, and
then have the students who have witnessed the performance write an
account of it, as in No. 2.

4. Divide the class into two groups. Select one person from each to look
at a picture as in No. 1. These two people are then to write a complete
account of the picture. This account is then read to another person in
the same group, who then writes from memory his account and reads to
another. This is to be continued till all have heard an account and
written their own. You will then have two series of accounts of the same
picture proceeding from two sou
