Values in brackets are the difference in DIC values (Δ DIC) from the model with the lowest DIC value (model 4 for the children and model 7 for the adults). Models including age as a covariate are not presented for adults as no age-related effects were expected in these participants. δ = drift rate; α = boundary separation; τ = non-decision time; EEG1 = slope of EEG reliable component 1; EEG2 = slope of EEG reliable component 2
