Sagittal and transverse views of the experimental contrasts during the study phase (learning the action sequences) at an uncorrected threshold of p < 0.001. Significant clusters (p < 0.05, FWE corrected) were found in the posterior cerebellum (Crus II) for the contrasts of (A) Social sequencing > Nonsequential control, (B) Nonsocial sequencing > Nonsequential control, (C) Social sequencing > Nonsocial sequencing, and the interaction (D) Social 40 s > Social 20 s = Nonsocial 20 s = Nonsocial 40 s. Note that for (C), the contrast was only marginally significant at p < 0.08 but was significant after applying a small volume correction centered around the posterior cerebellum (see text)
