The main conclusion drawn from the results of this experiment is that the activity of the listener rather than the metronome rate is the determining factor in the judgments of time during such periods. Thus under one set of conditions subjects found that time passed more rapidly at fast rates of the metronome than at slow rates; whereas under another set of conditions they showed just the reverse tendency, i.e., they found that time passed more rapidly at the slow rate. The determining variable seemed to be difficulty of activity rather than rate. In no case were the tasks of such difficulty that the subjects failed to perform them.
