The investigation of the relationship among lexical sophistication, receptive knowledge, and productive knowledge of vocabulary

This study explores the relationship between lexical sophistication indices and scores on both receptive and productive lexical knowledge. Essays written by Asian college students from the ICNALE(International Corpus Network of Asian Learners of English) corpus were selected. Scores from the Vocabulary Size Test (VST) were used as the measure of receptive lexical knowledge, whereas the vocabulary section scores on the essays were used as the measure of productive lexical knowledge. The following three research questions were addressed. First, what is the best lexical sophistication predictor of receptive lexical knowledge? Second, what is the best lexical sophistication predictor of productive lexical knowledge? Third, what are the overlapping lexical indices for predicting both receptive and productive lexical knowledge? Results showed that ‘strongly associated trigram sequences’ turned out to be the best predictor of receptive lexical knowledge, while ‘content words that on average are perceived to be learned later’ were the best predictor of productive lexical knowledge. Based on the findings of the current study, building on the core vocabulary (i.e., the overlapping predictors of both receptive and productive lexical knowledge) should take primacy for vocabulary instruction in writing courses.
