                                The duration after-effect does not reflect adaptation to perceived duration  Results Average PSEs for each of the adaptation conditions can be found in Figure 2. The depicted error bars represent within-subject standard errors calculated using per-subject normalization of the data (Cousineau, 2005; Morey, 2008). Error bars depicting the standard of the mean illustrate both the between- subject and within-subject variance in a dataset. These depictions describe the total variance in the data and can help indicated the variability across subjects. However, in a design focused on within-subject differences, error-bars depicting the standard error of the mean have little informational value about the outcome of the within-subject analyses (Cousineau, 2005). The within- subject standard errors used here reflect only the within-subject variability making them more predictive of the outcome of the analyses of the within- subject effects that were reported here. 600 550 BF10 = 7.42 4    500 450 400 350 300 250 200 BF10 = 23.97 BF10 = 0.264       Onset-Offset matched Illusion-inducing Perceived duration stimulus matched Figure 2. Average PSEs for each of the three Adaptation conditions. Average PSEs for when participants adapted to the onset-offset matched stimulus (300 ms, static), the illusion-inducing stimulus (300 ms, 8.33Hz), and the perceptually matched stimulus (M = 572.60 ms, static). BFs are given for all Bayesian paired sample t-tests with BF10 > 3 indicating evidence that the PSEs are different and BF10 < 1/3 indicating evidence that they are not. Error bars reflect confidence intervals based on the within-subject variability of the data (Cousineau, 2005; Morey, 2008). The PSE data were analyzed using a Bayesian repeated measures ANOVA with PSE as a dependent measure and Adaptation Type (onset-offset matched stimulus, illusion-inducing stimulus, perceptually matched stimulus) as a factor. This analysis revealed a main effect of Adaptation type (BF10 = 8.14). To gain insight into this main effect we conducted three subsequent pairwise 75 PSEs (ms)
