Note: t0 = non-decision time; z/a = response bias value (starting point value divided by boundary separation); νold = drift rate for target items; νnew = drift rate for target items; st = non-decision time variability; sz = starting point variability; sν = drift rate variability; p = values which indicate goodness-of fit. 1-day = 1-day study-test lag; 7-day = 7-day study-test lag. High = high-arousal; Low = low-arousal; Neg = negative; Pos = positive; Standard deviations are shown in parentheses.
