Sec. 5. PRACTICAL CONSIDERATIONS.


This method is so simple that it requires but little training on the
part of the experimenter, and but little co-operation on the part of
the subject. It is not to be assumed that every reaction obtained by
it is a true and immediate association to the corresponding stimulus
word; but we have found it sufficient for the purpose of the test if
the subject can be induced to give, in response to each stimulus word,
any one word other than the stimulus word itself. No attempt is made
to determine the exact degree of co-operation in any case.

In the early stages of this investigation the reaction time was
regularly recorded. The results showed remarkable variations, among
both normal and insane subjects. In a series of twenty-five tests,
