                                Chapter 5  150 trials for each unique combination with the Non-Occluded and Occluded conditions across the entire experiment. In total, participants completed 1050 trials spread over two 45-min sessions interrupted by a 15-min break. Results & discussion Because we presented randomly sampled durations between 1000 and 1600 ms, we first needed to calculate the reproduction error for each individual trial. To do this we calculated the ratio between the duration reproduced by the participants and the presented duration on each trial. Similar to the first experiment we then removed all individual trials with reproduction ratios two standard deviations larger or smaller than the mean for each condition, for each individual participant. This procedure resulted in the removal of 817 trials (3.71%). Next, we calculated the average reproduction ratio for each condition (Figure 4). 1.4 1.2 1 0.8 0.6 0.4 0.2 0 Static    Continuous   Disrupted                                                                                                                                                                                                                                                                                                                                             Non-Occluded Occluded Induction                Figure 4. Average Reproduction Ratios, plotted separately for each Occlusion (Non-Occluded, Occluded, Induction) and Temporal frequency condition (Static, Continuous, Disrupted). Induction data were provided for transparency but are not analyzed in the manuscript. A reproduction ratio of 1 reflects veridical reproductions, with lower values reflecting underestimation and higher values reflecting overestimation. Error bars reflect within-subject standard errors. The resulting data were analyzed in a 2 x 3 repeated-measures ANOVA with Reproduction Ratios as the dependent variable and Occlusion (Non- Occluded, Occluded) and Temporal frequency (Static, Continuous, Disrupted) as factors. As in Experiment 1 Greenhouse-Geisser corrections were used when the assumption of sphericity was violated. All post-hoc comparisons using t-tests were adjusted for multiple comparisons using the Holm-Bonferroni 96 Reproduction Ratio
