Figure 4. Interaction of choice and context in right dorsolateral prefrontal cortex.

Figure 4

a) In our factorial analysis of the fMRI data there was an effect in right DLPFC for the interaction of choice (accept > reject) and context (M-in-H > M-in-L). This activation survived whole-brain cluster-level correction (P<0.05 FWE corrected; threshold of P<0.005 used to define the cluster) and is displayed at P<0.001 (uncorrected) on slices through the peak voxel (x=33, y=48, z=24). b) To illustrate which differences drive the interaction we plot the regression coefficients (beta values +/− s.e.m.) for each condition versus baseline at the peak voxel for the interaction. Greater activation is seen for rejecting offers perceived as more fair than for those perceived as less fair (t(15)=3.3, P=0.005, two-tailed), with no difference during acceptance (t(15)=0.04, P>0.9, two-tailed).
