Word finding deficit is one of the language characteristics of children with specific language impairment(SLI). The present study was designed to compare word-finding abilities between children with SLI and normal children and to account for the word-finding problem in terms of lexical processing. Forty-five children participated in this study: 15 children with specific language impairment(SLI group) whose language age were 4;6-6;6, 15 normal children chronological-age matched with the SLI children(CA controls), and 15 normal children matched on a composite index of language age with the SLI children(LA controls). Pictures-naming task was used in two conditions to account for the lexical processing of children with SLI. The presentation of the pictures was preceded by a semantic-related priming in one condition, and a non-related priming in the other condition. Frequency and type of errors in picture naming task were analysed. The principal findings of the study were as follows: (1) The SLI group, the CA controls, and the LA controls produced less errors with semantic-related priming than non-related priming. This means that word- finding is improved by the semantic priming. (2) Error type analysis showed that in the SLI group the number of semantic errors changed less with semantic-related priming than the CA controls and the LA controls. The CA controls and the LA controls produced many more semantic errors and fewer of other of errors with semantic-related priming than non-related priming. The results of the study imply that children with SLI have difficulty in lexical processing on the semantic level.
