Comparison of TRACE with human behavior during learning. a Human behavior during transitions between a wide and narrow prior distribution in a time interval reproduction task similar to RSG. The data are adapted from previous work². The results were quantified by a previously reported ‘slope’ parameter that quantified the strength of the bias towards the mean of the prior (in this case, higher slope represents more bias toward the prior). The switch (vertical dashed line) from narrow (filled symbols) to wide (open symbols) decreases the influence of the prior and vice versa. b The corresponding prediction from TRACE (Methods section) indicates the expected timescales during the course of learning such priors. The change in PC activity compared to baseline is plotted on the ordinate (in arbitrary units). TRACE parameters were the same as those used in RSG and were not fit to the data
