Fig. 6: Results from Experiment 4.
a Smoothed response accuracy as a function of preparation time and previous error. Bold lines represent smoothed means, and ribbons represent smoothed 95% confidence intervals (i.e., standard error times 1.96). Note in the response preparation model, upper bound accuracy is controlled by the efficacy parameter β. b Model-estimated probability densities representing the time required to prepare responses following correct and incorrect trials. Densities were computed using group-level intercepts and slopes for μ and σ. Bold lines represent the posterior medians, and ribbons represent the 95% quantile intervals of the posterior. c Posterior (MCMC) distribution for group-level effects of previous error (Δ) on efficacy β. n = 46 human participants.
