摘要: In this study two new measures of lexical diversity are tested for the first time on French. The usefulness these measures, MTLD (McCarthy and Jarvis (2010 volume) ) HD-D 2007), in predicting different aspects language proficiency is assessed compared with D (Malvern Richards 1997; Malvern, Richards, Chipere Duran 2004) Maas (1972) analyses stories told by groups learners (n=41) levels one group native speakers French (n=23). importance careful lemmatization studies which involve highly inflected languages also demonstrated. paper shows that under valid proxies ability they explain up to 62 percent variance C-test scores, 33 a measure complexity. provides evidence dependence segment size continues be problem discussed paper. concludes limiting range text lengths or even keeping length constant safest option analysing diversity.
