proof of the truth of the statement that the animals
did not acquire a perfect labyrinth-A habit.
Was this due to inability to learn so complex a path,
or to the fact that the method is not adapted to their
nature? Observation of the behavior of the mice
in the experiments enables me to say with certainty
that there was no motive for escape sufficiently strong
to establish a habit of following the direct path.
Often, especially after a few experiences in the maze,
a dancer would wander back and forth in the alleys
and central courts, dancing much of the time and apparently
exploring its surroundings instead of persistently
trying to escape. This behavior, and the time
and error results of the accompanying table, lead
me to conclude that the labyrinth method, as it has
been employed in the study of the intelligence of
several other mammals, is not a satisfactory test of
the ability of the dancer to profit by experience.
That the fault is not in the labyrinth itself is proved
by the results which I obtained with common mice.
