highly significantp < 0.0001
There was a highly significant body region by modality interaction for both simultaneous ( F 2,30 = 23.8, p < 0.0001) and successive 2PD ( F 2,18 = 93.8, p < 0.0001), but no main effect of either factor (simultaneous 2PD: both factors, F < 1; successive 2PD: body region, F 2,18 = 3.0, p = 0.075; modality, F < 1).
