Behavioural fexibility is essential for everyday life. This involves shifting attention between diferent
perspectives. Previous studies suggest that fexibility is mainly subserved by the dorsolateral prefrontal
cortex (DLPFC). However, although rarely emphasized, the temporoparietal junction (TPJ) is frequently
recruited during fexible behaviour. A crucial question is whether TPJ plays a role in diferent types of
fexibility, compared to its limited role in perceptual fexibility. We hypothesized that TPJ activity during
diverse fexibility tasks plays a common role in stimulus-driven attention-shifting, thereby contributing
to diferent types of fexibility, and thus the collaboration between DLPFC and TPJ might serve as a
more appropriate mechanism than DLPFC alone. We used fMRI to measure DLPFC/TPJ activity recruited
during moral fexibility, and examined its efect on other domains of fexibility (economic/perceptual).
Here, we show the additional, yet crucial role of TPJ: a combined DLPFC/TPJ activity predicted
fexibility, regardless of domain. Diferent types of fexibility might rely on more basic attentionshifting,
which highlights the behavioural signifcance of alternatives.
