We drew a virtual sample of different lexicon sizes from a corpus and let the virtual sample "take" a vocabulary test by comparing whether the items were included in the virtual lexicons or not. This enabled us to…

We found that different skills predicted the development of each. Reading comprehension skill measured in Year 3 was a strong predictor of comprehension in Year 6;…
