2. Perform an experiment to determine how each member of the class
thinks, _i.e._ in what kind of imagery. Let each plan a picnic in
detail. How do they do it? Do they see it or hear it or seem to act it?
Or does it happen in words merely?

3. Think of the events of yesterday. How do they come to you? Do your
images seem to be visual, auditory, motor, or verbal? Do you seem to
have all kinds of imagery? Is one kind predominant?

4. Test the class for speed of free association as described on
page 193. Repeat the experiment at least five times and rank the members
of the class from the results.

5. Similarly, test speed for controlled association as described on
page 195 and rank the members of the class.

6. Compare the rankings in Nos. 4 and 5.

7. The teacher can extend the controlled association tests by preparing
lists that show different kinds of logical relations with one another,
from genus to species, from species to genus, from verb to object, from
subject to verb, etc. Do the students maintain the same rank in the
various types of experiments? Do the ranks in these tests correspond to
the students' ranks in thinking in the school subjects?

8. At least two series of experiments in reasoning should be performed,
one to show the nature of reasoning and the other to show the ability of
the members of the class.

(a) Put several problems to the class, similar to the following: What
happens to a wet board laid out in the sunshine? Explain. Suppose corn
is placed in three vessels, 1, 2, and 3. Number 1 is sealed up air tight
and kept warm? Number 2 is kept open and warm? Number 3 is kept open and
warm and moist. What happens in each case? Explain.

Condensed milk does not sour as long as the can remains unopened. After
the can is opened, the milk sours if allowed to become warm; it does not
sour if kept frozen. Why? Two bars of metal are riveted together. One
bar is lead, the other iron. What happens when the bars are heated to
150 C? 500 C? 1000 C? 2000 C? Answer the following questions: Is it ever
right to steal? To kill a person? To lie? Which are unwise and mistaken,
Republicans or Democrats?

In the above, do all come to the same conclusion? Why? Were any unable
to come to a conclusion at all on some questions? Why? Do the
experiments make it clear that reasoning is dependent upon experience?

(b) Let the teacher prepare five problems in reasoning well within the
experience of the class, and fin
