Zusammenfassung

We used fMRI to investigate both common and differential neural mechanisms underlying two distinct types of switching requirements, namely switching between stimulus categorizations (colour vs. form) and switching between response modalities (hand vs. foot responses). Both types of switching induced similar behavioural shift costs. However, at the neural level, switching between stimulus categorizations led to left-hemispheric activations including the inferior frontal gyrus as well as the intraparietal sulcus extending to the superior parietal gyrus and the supramarginal gyrus. In contrast, switching between re…
