Objective: Language deficits are common in Autism Spectrum Disorders (ASD). This study investigated whole-brain patterns of neural synchrony during rest in ASD and neurotypicals (NT) to: examine differences in phonological processing (PP) and identify relationships between neural synchrony and phonological processing. Method: Twelve ASD (Age: M = 9.1; SD = 1.0) and 13 NT (Age: M = 9.3; SD = 1.2) children were recruited. Cortical activity was recorded using 148-channel, whole-head magnetoencephalography (MEG). Synchronization was quantified by calculating coherence between cortical sites. T-tests were computed to assess group differences in PP and coherence between each pair of brain regions (N = 1,431). Kendall Tau correlations were computed to explore relationships between coherence and phonological processing using Elision (EL) and Blending Word (BW) of the Comprehensive Test of Phonological Processing. Results: ASD and NT did not significantly differ in EL (p = 0.89) and BW (p = 0.73) scores. In ASD,...
