Note—Parameters are evidence threshold (a), (mean) drift rates (v), drift rate standard deviation (η), (mean) non-decision time (T_er), and variation of non-decision time (s_t). The guessing parameter (p_g) refers to the percentage of trials in which the content in VSTM was lost. Parameters in parentheses are fixed. Starting point was fixed (z = a/2, s_z = 0). F- and p-values refer to results of group comparisons (ANOVA), the adjusted p-values (p_adj) were obtained after FDR correction.
