Some researchers have proposed that language impairment results from immature auditory temporal integration (ATI), which limits the perception of rapidly presented auditory information such as phonemes. To characterize ATI in children with Specific Language Impairment (SLI) at the neural level, we compared electroencephalographic data for 25 children with SLI aged 6-11 years to 25 typically developing children. Participants’ responses to 50ms tones presented alone or in pairs separated by silent gaps of 100, 200, 300 or 400ms were compared using mixed ANOVA. The TD and SLI groups did not significantly differ in strength and timing of brain responses to auditory stimuli (P1 and N2) across conditions. Both groups showed attenuated, but present, responses to the second tone even in the shortest gap condition. Although these results did not provide evidence for ATI impairments in SLI, further research using smaller gaps is required before conclusions can be drawn.
