It also examines the relationship between the speaking and writing attainment, and the extent to which the link between performance in aptitude and speaking differs from the one for writing. Oral and written picture narratives elicited from 30 ESL speakers were analyzed and coded in terms of lexical and morphosyntactic errors per 100 words. The results of the Spearman correlation analyses revealed that vocabulary learning aptitude is significantly associated with the command of lexis and morphosyntax in writing, explicit grammar learning aptitude shows no significant association with accuracy in both production modes, and time availability in writing has no influence on the interplay between explicit and implicit knowledge with regard to the access of lexical forms. No significant differences were found with respect to the strength of aptitude-speaking and aptitude-writing relations.Show less
