The study from Xiaolin Zhou's group addressed the ongoing debates regarding the extent to which information from one modality dominates or interferes with the processing of information from another modality. These debates may be due to the lack of differentiating the different processing stages of cross-modal interaction in previous studies. By differentiating cross-modal conflict into pre-response and response levels, this study provided both behavioral and neural evidence, showing that vision dominates at earlier stages, whereas audition dominates at later stages of cognitive processing.
