A single rat given 6000 trials (50 trials per day) for a period of four months on a dual choke apparatus, showed no ability to reduce the time in turning from one learned stimulus (a light) to the opposite stimulus (no light). No evidence of insight was found but merely rote or mechanical learning. A human being would probably solve such a problem quickly by means of verbal cues. A possible interpretation that the old habit is not "torn down" but only inhibited or suppressed. Same results found with three other rats given 2000 trials each.
