In managing our daily lives, we need to regulate information perceived from different modalities. It has been suggested that the inputs from these sensory channels are processed to some extent in independent modules (Fodor, 1983). The question whether executive control is module-specific or cross-modal in nature remains open.

In this study we focused on executive processes of switching and conflict resolution in both the tactile and visual modality. We explored the interaction of simultaneous and sequential implementation of executive control processes between and within modalities. Our results revealed asymmetric mixing costs and congruency effects between the tactile and visual modality. Switching cost was larger following incongruent trials, leading to the idea set switching and conflict monitoring are two different mechanisms of control, competing over resources and affecting each others' performance. Whether control is shared by various modalities or modality-specific is yet to be resolved.
