In both experiments, brain regions demonstrating greater activation for the 4vis condition as compared to the 2vis condition in conjunction with greater activation for the 2vis2aud condition as compared to the 2vis condition [(4vis>2vis) && (2vis2aud>2vis)]. Experiment 1 results are shown in blue; Experiment 2 results, in green; overlap of the resulting two maps, in red. Results are viewed on the inflated surface of an exemplar brain. In all instances, p< .05, false-discovery-rate corrected.
