Table 4.
Means, standard deviations, and ranges for the cognitive predictor variables for the group with DLD and the TD group having 100% correct RAN performance.
| Group | Word recognition |
pWM c | Updating d | Switching e | Inhibition f | |
|---|---|---|---|---|---|---|
| POI a | POF b | |||||
| DLD (n = 60) | ||||||
| Mean | 196.2 | 263.7 | 80.1* | 3.5 | 82.4 | 82.2 |

Note. DLD = developmental language disorder; RAN = rapid automatic naming task; TD = typically developing.
