Did the [+LD] group perform worse than their [-LD] counterparts? This was
the issue that arose from Schelletter et al. (1996), referred to earlier.

(No significant between-group differences)
Although the mean number of alternations produced was slightly lower in the
SLI group with a lexical deficit than in the group without a lexical deficit, the
difference was not statistically significant. Hence argument structure
realisation appears not to be related to the child’s level of lexical acquisition.
