Table 1.
MNI coordinates of brain regions showing a significant main of effect of Trial (Alt > Rep), a significant main effect of Block (Alt > Rep), and a positive correlation between AQ scores and perceptual expectation [(Alt Trial Rep Block > Rep Trial Rep Block) > (Alt Trial Alt Block > Rep Trial Alt Block)] (covarying out effects of age). All activations significant at p < .001 uncorrected (10 contiguous voxels) at the whole-brain level.
