Model fit results for study 2. (A) The summed BIC for each model. (B) The 95%CI of the summed BIC difference between each model pair obtained using bootstrapping. Lower BIC values indicate a better fit. This shows that the Uncertainty model fitted best. (C) The Uncertainty model fit for the positively biased data. The line graphs represent the raw data and SEM, which show that the effect of condition replicates in both biased conditions. Shaded region is the model fit. (D) The Uncertainty model fit for the negatively biased data.
