Spatial coordinates of the local maxima of brain regions showing significant effects in the different contrasts
| Contrast | Anatomical region | t value | Cluster size | Corrected p value | Stereotactic coordinates (x, y, z) |

| R ventral striatum | 11.08 | 1046 | <0.0001 | 14, 6, −12 | |

Stereotactic coordinates correspond to the standard Montreal Neurological Institute brain.
**Neither the remaining two-way interactions nor the three-way interaction (agency × correctness × context) showed any significant activations. R, Right; L, left.
