Performance strategies. Scatterplots (with reference lines at x = 0 and y = 0) show associations between ΔRT and relative change index for false alarm rates within each of the two groups and for the two reward conditions. Positive ΔRT values indicate RT slowing from baseline to the reward condition, and positive false alarm rates indicate improvement of inhibition performance from baseline to the reward condition. Social reward: control group, r = -0.26, p = 0.33; ADHD group, r = 0.14, p = 0.59. Money reward: control group, r = 0.37, p = 0.16; ADHD group, r = 0.44, p = 0.09.
