Table 1.
Behavioral performance variables during the fMRI sessions for the trained and untrained sequences. A paired t-test for the difference between sessions is reported
| Trained | Untrained | t(15) | p | |
|---|---|---|---|---|
| MT (ms) | 1209 (297) | 1341 (286) | −3.37 | 0.004 |
| Force (N) | 4.44 (0.63) | 4.0 (0.49) | 3.09 | 0.007 |
| Error rate (%) | 12.26 (6.75) | 12.22 (4.57) | 0.02 | 0.986 |
| ACC (%) | 58.98 (17.86) | 60.55 (11.11) | −0.35 | 0.732 |
MT is the total movement time in ms. The Force is the maximal force produced for each finger, averaged across the fingers. Error rate (%) indicates the percentage of trials containing an incorrect finger press. Accuracy is the classification obtained when distinguishing the four trained or untrained sequences based on MT, force, and error rate.
