Peak amplitude and latency. (A) Peak amplitude in Stim-1 (left) and Stim-2 (right). For Stim-1, no significant effect was observed. For Stim-2, the 3-way interaction was significant. Subsequent analysis revealed that both orientation and two-agent interaction effect was significant in the right hemisphere. In the left hemisphere, 2-way interaction between orientation and two-agent interaction was significant (see text). (B) Peak latency in Stim-1 (left) and Stim-2 (right). No significant effect was observed for either Stim-1 or Stim-2. Error bar indicates the standard error of the mean (S.E.M.). * p < 0.05, ** p < 0.01.
