By reading downward in any particular column of results, one obtains a
description of the changes in the animal's reaction to a particular
setting of the doors. Thus, for instance, in the case of setting 1,
which was presented to the animal in trials numbered 1, 11, 21, and so
on to 141, it is clear from the records that no definite improvement
occurred. But oddly enough, in the case of setting 10, which presented
the same group of open doors, almost all of the reactions are right in
the lower half of the column. For setting 2, it is evident that mistakes
soon disappeared.

Comparison of the data of table 1 indicates that the number of correct
first choices is inversely proportional to the number of doors in use,
while the number of choices made in a given trial is directly
proportional to the number of doors in use.
