Neural mediators of changes of mind about perceptual decisions
Open accessAbstract
Changing one's mind on the basis of new evidence is a hallmark of cognitive flexibility. To revise our confidence in a previous decision, we should use new evidence to update beliefs about choice accuracy. How this process unfolds in the human brain, however, remains unknown. Here we manipulated whether additional sensory evidence supports or negates a previous motion direction discrimination judgment while recording markers of neural activity in the human brain using fMRI. A signature of post-decision evidence (change in log-odds correct) was selectively observed in the activity of posterior medial frontal cortex. In contrast, distinct activity profiles in anterior prefrontal cortex mediated the impact of post-decision evidence on subjective confidence, independently of changes in decision value. Together our findings reveal candidate neural mediators of post-decisional changes of mind in the human brain and indicate possible targets for ameliorating deficits in cognitive flexibility.

The folded X signature was observed in the fMRI activity of pMFC.
“This folded X signature was observed in the fMRI activity of pMFC, consistent with this region (negatively) accumulating evidence in a frame of reference of choice accuracy and providing a computational bridge between studies on confidence and on error monitoring.”

In a random dot motion discrimination study, providing stronger postdecision evidence led to a stronger folded X pattern in confidence ratings.
“In a study of random dot motion discrimination, providing stronger postdecision evidence indeed led to a stronger folded X pattern in confidence ratings (Fleming et al. 2018).”

fMRI neural correlates of evidence against a choice are tracked in pMFC (the neural generator of the ERN), whereas more anterior prefrontal regions covary with subjective confidence.
“Consistent with this perspective, fMRI neural correlates of evidence against a choice were tracked in pMFC (the neural generator of the ERN), whereas more anterior prefrontal regions covaried with subjective confidence (Fleming et al. 2018).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
