Supplementary Figure 3: Choice behavior of patient cohorts in comparison with age-matched controls.
From: Damage to dorsolateral prefrontal cortex affects tradeoffs between honesty and self-interest
(a) Identical to Fig. 2B, except healthy participants have been partitioned such that they age-match patient cohorts on both mean and standard deviation. Consistent with results from the combined healthy comparison cohort, DLPFC cohort differed significantly from their age-matched healthy controls in terms of the paired difference in amount given between the Message and Choice conditions (Kruskal–Wallis test, p<.001, two-tailed), whereas this paired difference was similar between OFC and their age-matched controls (Kruskal–Wallis test, p<.50, two-tailed). (b) Identical to Fig. 2C, except healthy comparison participants were partitioned to age-match patient cohorts on both mean and standard deviation. Consistent with results from the combined healthy comparison cohort, DLPFC cohort differed significantly from their age-matched healthy controls in terms of the proportion of honest decision during conflict trials (Fisher’s exact test, p<.01, two-tailed) but not during no conflict trials (Fisher’s exact test, p>.50, two-tailed).
