Sentence repetition has been widely used to asse ss linguistic deficits in individuals with developmental language disord ers (DLD), yet its fundamental mechanism has not been fully explained. O ne of the critical factors is the sentence superiority effect (SSE), the processing benefit of recalling words in a sentence compared to a rando m sequence of words due to the existence of sentence structure that miti gates processing costs. The current study investigated the role of SSE i n sentence repetition in neurotypical adults by examining the difference s in neural oscillations in delta (1-4Hz) and beta (13-30Hz) frequency b ands using electroencephalography (EEG). The results showed a general de synchronization in the delta and beta bands in all conditions. SSE was f ound in both frequency bands, with greater power in sentences than in wo rd lists, especially when there was background noise. Also, sentence rep etition accuracy was negatively correlated with delta and beta frequency power. The results provide partial support for the information via desy nchronization hypothesis, suggesting that a decrease in beta power plays an important role in memory retrieval. Future studies involving partici pants with DLD are needed to fully understand the role of SSE in sentenc e repetition when assessing linguistic difficulties in individuals with DLD.
