Dyslexic cases in ILTS: Cross tabulation of overall model fit, based on the “counting deficits” and individual regression fit methods applied to individual cases
| Deficit | PA only | L only | NS only | PA and L | PA and NS | L and NS | PA, L, & NS | None | Total | |
|---|---|---|---|---|---|---|---|---|---|---|
| Best Fitting Model | PA | 10 | 0 | 0 | 5 | 2 | 0 | 0 | 12 | 29 |
| L | 0 | 2 | 0 | 0 | 0 | 0 | 0 | 1 | 3 | |
| NS | 0 | 0 | 11 | 0 | 2 | 0 | 5 | 3 | 21 | |
| Multiple | 3 | 0 | 7 | 1 | 5 | 1 | 2 | 10 | 29 | |
| Total | 13 | 2 | 18 | 6 | 9 | 1 | 7 | 26 | 82 | |
Note. ILTS = International longitudinal Twin Study; PA = phoneme awareness; L = language skill; PS = processing speed; NS = naming speed.
