|---|---|---|---|---|---|---|
| Type 1 cases, mean (SD) | Type 2 cases, mean (SD) | Type 2 − Type 1, t-value (df = 16) | Type 1 cases, mean (SD) | Type 2 cases, mean (SD) | Type 2 − Type 1, t-value (df = 15) | |
| Case processing time (s) | 39 (14) | 55 (17) | 2.88a | 21.6 (6.2) | 26.3 (9.0) | 4.74b |
| Diagnostic accuracy | 1.87 (0.12) | 1.64 (0.12) | −5.05b | 1.81 (0.16) | 1.61 (0.26) | −2.72a |

| Difficulty | 32 (15) | 46 (15) | 2.30a | 26 (12) | 40 (15) | 4.74b |
| Effort | 32 (13) | 45 (14) | 2.51a | NAc | NAc | NAc |
Notes: The data for the case pilot validation study include five cases that were not selected for the final fMRI study. Diagnostic accuracy was scored as 0 (incorrect diagnosis), 1 (partially correct diagnosis) or 2 (correct diagnosis). Confidence and difficulty were provided on a Likert-type scale from 1 (not at all confident/difficult) to 7 (very confident/difficult) in the fMRI experiment and transformed to a percentage for this table.
Difference between Type 1 and Type 2 cases is significant at P < 0.05.
Difference between Type 1 and Type 2 cases is significant at P < 0.001.
