Descriptive statistics for each test
| Test | Mean (SD) | Reliability |
|---|---|---|
| hNOMT-buttons (percent accuracy) | 83.23% (8.78%) | 0.72 |
| hMatch-Spaceships (percent accuracy, d`) | 75.27% (8.61%), 1.43 (0.57) | 0.67, 0.54 |
| vNOMT-Ziggerins (percent accuracy) | 64.71% (12.82%) | 0.78 |
| vMatch-Sheinbugs (percent accuracy, d`) | 56.51% (5.41%), 0.36 (0.29) | 0.75, 0.71 |
| ov (mean z-score) | 0 (0.80) | 0.80 |
| RAPM (total correct) | 10.58 (2.94) | 0.67 |
Reliability for individual tests are Spearman-Brown reliability for matching tests with d’ and McDonald’s omega otherwise. ov reliability is aggregate reliability of vMatch-Sheinbugs and vNOMT-Ziggerins with equal weighting (Wang & Stanley, 1970). RAPM has a maximum score of 18
