Summary
Specific language impairment (SLI) is a communication disorder that impedes the development of language skills without the presence of intellectual disabilities, hearing loss, or any other medical conditions. Evaluating a child, who may have SLI, using sentence processing tasks, allows a clinician to evaluate their lexical-semantic development compared to their typically developing (TD) peers. Furthermore, using event related potential (ERP) data, specifically the N400 and P600 components, can give clinicians insight into the child's neural activity in relationship to their sentence processing, since these components relate to semantic and syntactic abilities. For this systematic review, forty-three articles were found through both PubMed and PsychINFO databases. Abstracts were examined to determine if the articles met the inclusion criteria: (1) a SLI or DLD child subgroup, (2) a semantic or syntactic task, (3) experimental testing seeking to show either a N400 effect or P600 effect. The full articles were then examined further and eleven articles were included in the review. The literature did not reveal any specific patterns between the ERP patterns of children with SLI and their TD peers. About half of the articles did not find a main effect of group while the remaining articles found a significant main effect of group. These differences may be due to the differences in samples and stimuli included in the studies. Further research should be conducted to investigate the N400 effect and P600 effect in children with SLI compared to their TD peers during semantic and syntactic tasks.
