Relationship between pre-movement decoding accuracy and the movement related potential (MRP). (A) The median area under the MRP curve plotted against the mean decoding accuracy for each subject and condition. A negative value of MRP area under the curve indicates the presence of larger MRPs. The coefficient of determination (R²) is indicated. (B) The change in decoding accuracy across conditions plotted against the change in area under the MRP curve for each subject. A large negative value for change in area indicates a stronger MRP presence during the self-initiated condition, while a large positive value indicates a stronger MRP presence during the triggered condition; values close to zero indicate similar MRPs for both conditions. The coefficient of determination (R²) is indicated. The two participants with the largest difference in accuracy across conditions are indicated by the arrows.
