Results Behavioural data We observed a highly significant main effect of endogenous effort modulation on RTs for correct trials (EXR-RLX: F (1,44) = 30.30, p = 1.79e-06), in addition to the expected main effect of stimulus type (incongr-congr: F (1,44) = 1437.20, p = 3.07e-35).

In addition to the expected large effect of stim ( F (1,44) = 83.29, p = 1.04e-11), we observed a marginally significant stim × cond interaction ( F (1,44) = 4.22, p = 0.046); no other effect was significant.
