Abstract

Differences in prosody (e.g., intonation, rhythm) are among the most obvious language‐related impairments in autism spectrum disorder (ASD), and significantly impact communication. Subtle prosodic differences have also been identified in a subset of clinically unaffected first‐degree relatives of individuals with ASD, and may reflect genetic liability to ASD. This study investigated the neural basis of prosodic differences in ASD and first‐degree relatives through analysis of feedforward and feedback control involved in the planning, production, self‐monitoring, and self‐correction of speech by using a pitch‐perturbed auditory feedback paradigm during sustained vowel and speech production. Results revealed larger vocal response magnitudes to pitch‐perturbed auditory feedback across tasks in ASD and ASD parent groups, with differences in sustained vowel production driven by parents who displayed subclinical personality and language features associated with ASD (i.e., broad autism phenotype). Both ASD and ASD parent groups exhibited increased response onset latencies during sustained vowel production, while the ASD parent group exhibited decreased response onset latencies during speech production. Vocal response magnitudes across tasks were associated with prosodic atypicalities in both individuals with ASD and their parents. Exploratory event‐related potential (ERP) analyses in a subgroup of participants during the sustained vowel task revealed reduced P1 ERP amplitudes in the ASD group, with similar trends observed in parents. Overall, results suggest underdeveloped feedforward systems and neural attenuation in detecting audio‐vocal feedback may contribute to ASD‐related prosodic atypicalities. Importantly, results implicate atypical audio‐vocal integration as a marker of genetic risk to ASD, evident in ASD and among clinically unaffected relatives.

Lay Summary: Previous research has identified atypicalities in prosody (e.g., intonation) in individuals with ASD and a subset of their first‐degree relatives. In order to better understand the mechanisms underlying prosodic differences in ASD, this study examined how individuals with ASD and their parents responded to unexpected differences in what they heard themselves say to modify control of their voice (i.e., audio‐vocal integration). Results suggest that disruptions to audio‐vocal integration in individuals with ASD contribute to ASD‐related prosodic atypicalities, and the more subtle differences observed in parents could reflect underlying genetic liability to ASD.

  • Some ASD studies focused on early ERP components mainly show reduced P1 latencies and amplitude.

    “Some ASD studies have focused on early ERP components (Table 6), mainly showing reduced P1 latencies and amplitude (Patel et al. 2019; Arnett et al. 2018; Bidet-caulet et al. 2017).”

    The Results (Sustained Vowel Task; page not provided) report significantly reduced P1 ERP amplitude in the ASD group, but no significant group effect on P1 ERP latency. Thus, this paper supports the amplitude finding, not reduced P1 latency in ASD. (LLM, conf=0.90)

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.
