Abstract

Abnormal auditory discrimination neural processes, indexed by mismatch fields (MMFs) recorded by magnetoencephalography (MEG), have been reported in verbal children with ASD. Association with clinical measures indicates that delayed MMF components are associated with poorer language and communication performance. At present, little is known about neural correlates of language and communication skills in extremely language impaired (minimally‐verbal/non‐verbal) children who have ASD: ASD‐MVNV. It is hypothesized that MMF delays observed in language‐impaired but nonetheless verbal children with ASD will be exacerbated in ASD‐MVNV. The present study investigated this hypothesis, examining MMF responses bilaterally during an auditory oddball paradigm with vowel stimuli in ASD‐MVNV, in a verbal ASD cohort without cognitive impairment and in typically developing (TD) children. The verbal ASD cohort without cognitive impairment was split into those demonstrating considerable language impairment (CELF core language index <85; “ASD‐LI”) versus those with less or no language impairment (CELF CLI >85; “ASD‐V“). Eighty‐four participants (8‐12 years) were included in final analysis: ASD‐MVNV: n = 9, 9.67 ± 1.41 years, ASD: n = 48, (ASD‐V: n = 27, 10.55 ± 1.21 years, ASD‐LI: n = 21, 10.67 ± 1.20 years) and TD: n = 27, 10.14 ± 1.38 years. Delayed MMF latencies were found bilaterally in ASD‐MVNV compared to verbal ASD (both ASD‐V and ASD‐LI) and TD children. Delayed MMF responses were associated with diminished language and communication skills. Furthermore, whereas the TD children showed leftward lateralization of MMF amplitude, ASD‐MVNV and verbal ASD (ASD‐V and ASD‐LI) showed abnormal rightward lateralization. Findings suggest delayed auditory discrimination processes and abnormal rightward laterality as objective markers of language/communication skills in both verbal and MVNV children who have ASD.

Lay Summary: Brain imaging showed abnormal auditory discrimination processes in minimally‐verbal/non‐verbal children (MVNV) who have autism spectrum disorder (ASD). Delays in auditory discrimination were associated with impaired language and communication skills. Findings suggest these auditory neural measures may be objective markers of language and communication skills in both verbal and, previously‐understudied, MVNV children who have ASD.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
