Procedia - Social and Behavioral Sciences,
In this study, 22 children with early left hemisphere (LHD) or right hemisphere (RHD) focal brain lesions (FL, n ¼ 14 LHD,\ud n ¼ 8 RHD) were administered an English past tense elicitation test (M ¼ 6:5 years). Proportion correct and frequency of overregularization\ud and zero-marking errors were compared to age-matched samples of children with specific language impairment (SLI,\ud n ¼ 27) and with typical language development (TD, n ¼ 27). Similar rates of correct production and error patterns were observed\ud for the children with TD and FL; whereas, children with SLI produced more zero-marking errors than either their FL or TD peers.\ud Performance was predicted by vocabulary level (PPVT-R) for children in all groups, and errors did not differ as a function of lesion\ud side (LHD vs. RHD). Findings are discussed in terms of the nature of brain–language relations and how those relationships develop\ud over the course of language learning.
