Note: HR = hit rate; FAR = false alarm rate; d’ = discriminability index; RTHit = reaction time for hits; RTCR = reaction time for correct rejections; 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. 1-day = 1-day study-test lag; 7-day = 7-day study-test lag. Neg = negative; Pos = positive; Neu = neutral. Standard deviations are shown in parentheses. Outlier trials removed.
