Trial-to-trial RT adjustments in a single subject in a) CEV, b) CEVR, c) DEV, and d) IEV. Model Go and NoGo terms (magnified by 4x) accumulate as a function of positive and negative prediction errors. Go dominates over NoGo in DEV and the reverse in IEV, but these incremental changes do not capture trial-by-trial dynamics. For this subject, = 0.63 and = 0.74 (ms/point).
