It is the consensus that, as a result of the extra constraints placed on working memory, texts written in a second language (L2) are usually of lower quality than texts written in the first language (L1) by the same writer. However, no method is currently available for quantifying the quality difference between L1 and L2 texts. In the present…

Practitioners working closely with second language (L2) writers in the US recognize at least two types of L2 students: international (IL2) and Generation 1.5 (G1.5) students. Some argue that specific differences in each group's writing performance are evident (cf. Harklau, 2003; Reid, 2006); however, investigations into observable and measurable…

Compares accuracy of five formulae in terms of their ability to model the type-token curves of written texts produced by learners and native speakers. The most accurate models are then used to consider unresolved issues of past research on lexical diversity: the relationship between lexical diversity and age, second language instruction (L2), L2…
