Results of Experiment 4.

<p>Mean temporal productions were longer for novel stimuli, which would usually be taken to indicate shorter subjective duration for these items – contrary to the results of Experiments 1, 2, and 3A. If the difference between novel stimuli and repeats reflected a difference in the rate of an internal pacemaker then the effect would become more pronounced at longer durations. In fact, the effect of repetition was independent of duration – and inspection of the figure suggests that, if anything, the difference between conditions is smaller at longer durations. Error bars show plus/minus one SEM, calculated separately for each data point. Again, these provide no indication of the significance of differences between conditions.
