t is not always easy to draw the line
between satisfactory and unsatisfactory responses. The following sample
performances will serve as a guide:--

_Selection (a)_

_Satisfactory._ "The tests which we are making are given for the
advancement of science and for the information of the person
tested. By scientific means we will be able to separate
characteristics derived from heredity and environment and to
treat each class separately. By doing so we can more accurately
correct defects."

"Tests like these are for two purposes. First to develop a
science, and second to apply it to the person to help him. The
tests are to find out how you differ from another and to measure
the difference between your heredity and environment."

"These tests are given to see if we can separate heredity and
environment and to see if we can find out how one person differs
from another. We can then correct these differences and teach
people more effectively."

"The tests that we are now making are valuable along both
scientific and personal lines. By using them it can be found out
where a person is weak and where he is strong. We can then
strengthen his weak points and remedy some things that would
otherwise be neglected. They are of great benefit to science and
to the person concerned."

"Tests such as we are now making are of great importance because
they aim to show in what respects we differ from others and why,
and if they do this they will be able to guide us into the right
channel and bring success instead of failure."

_Unsatisfactory._ "Tests such as we are now making are of value
both for the advancement of science and for the information of
the person interested. It is necessary to know this."

"Such tests as we are now making show about the human mind and
show in what channels we are fitted. It is the testing of each
individual between his effects of inheritancy and environment."

"It is very interesting for us to study science for two reasons;
first, to test our mental ability, and second for the further
development of science."

"Tests such as we are now making help in two ways; it helps the
scientists and it gives information to the people."

"Tests are being given to pupils to-day to better them and to
aid science for generations to come. If each person knows
