| MT reading speed | 38.98 | 9.54 | 26.06 | 4.51 |
| MT reading errors | 6.30 | 2.66 | 3.20 | 1.62 |
| Regular words 1:1 spelling accuracy (n = 70) | 22.93 | 2.55 | 24.87 | 0.35 |
| Context-sensitive words spelling accuracy (n = 10) | 68.53 | 1.06 | 69.40 | 0.83 |
| Ambiguous words spelling accuracy (n = 55) | 9.60 | 0.83 | 9.87 | 0.35 |
| Pseudowords spelling accuracy (n = 25) | 45.40 | 4.21 | 50.40 | 3.38 |

Note: Regular words 1:1 = words with one-sound-to-one-letter correspondence; context-sensitive words = words requiring the application of context-sensitive sound-to-spelling rules; ambiguous words = words with unpredictable transcription along the phonology-to-orthography conversion routine.
