Experiment 1: Short Uniform and Long Uniform blocks.

<p><i>Very top:</i> Experimental distributions for Short Uniform (red) and Long Uniform (green) blocks, repeated on top of both columns. <i>Left column:</i> Mean response bias (average difference between the response and true interval duration, top) and standard deviation of the response (bottom) for a representative subject in both blocks (red: Short Uniform; green: Long Uniform). Error bars denote s.e.m. Continuous lines represent the Bayesian model ‘fit’ obtained averaging the predictions of the most supported models (Bayesian model averaging). <i>Right column:</i> Mean response bias (top) and standard deviation of the response (bottom) across subjects in both blocks (mean s.e.m. across subjects). Continuous lines represent the Bayesian model ‘fit’ obtained averaging the predictions of the most supported models across subjects.
