The naming and drawing responses of a child with speci® c language impairment (age 5.5 years) were used to test the hypothesis that de® cient storage in the mental lexicon plays a role in the naming problems associated with SLI. In confrontationand repeated naming, the child demonstrated frequent semantic substitutions and occasional phonologic substitutions. Stochastic modelling of his repeated naming revealed storage de® cits to be a source of these errors. Comparative picture naming, picture

Phonological naming errors, in contrast, were typically associated with strong semantic representations. Clinical, theoretical, and methodological contributions of this cognitive neuropsychological case study are discussed.
