problem Sobke worked remarkably well, but later his willingness
diminished, evidently because of his failure readily to solve the
problem, and it became extremely difficult to coax him into the
apparatus. On days when he entered only reluctantly and as it seemed
against his will, he was likely to be nervous, erratic, and often slow
in making his choices, but above all he tended to waste time by not
returning to the starting point, preferring rather to loiter in the
alleyways or run back and forth.
