Larger tonic pupil size in young children with autism spectrum disorder

Abstract

The symptoms of Autism Spectrum Disorder (ASD) have been suggested to manifest from atypical functioning of the autonomic nervous system (ANS), leading to altered arousal and atypical processing of salient stimuli. Coherent with this, persons with ASD show heightened autonomic activity, sleep difficulties, and structural and neurochemical alterations within the ANS. Recently, we observed decreased pupil responses to human faces in children with ASD. In the current study, we found differences in baseline (tonic) pupil size, with the ASD group exhibiting a larger pupil size than age‐matched controls. Pupil responses are sensitive and reliable measures of ANS functioning, thus, this finding highlights the role of the ANS, and may provide clues about underlying neuropathology. © 2008 Wiley Periodicals, Inc.

  • Children with ASD have larger tonic pupil size.

    “More recently, evidence of larger tonic pupil size in children with ASD has also been found (Anderson & Colombo, 2009).”

  • Compared with typically developing children, 4-year-old children with ASD have increased tonic pupil size, indicating increased arousal.

    “a more recent study by Anderson and Colombo (2009) reported that compared to TD children, 4-year-old children with ASD exhibit increased tonic pupil size, which is indicative of increased arousal.”

  • Increased tonic pupil size has been observed in young children with ASD.

    “More recently, increased tonic pupil size in young children with ASD has been observed (Anderson & Colombo, 2009).”

    From Atypical attentional networks and the emergence of autism (2013) · cites this paper as Anderson & Colombo, 2009

  • Higher arousal in ASD and related conditions at later stages of development has been reported using a variety of indices, including tonic pupil size, respiratory sinus arrhythmia, baseline heart rate and galvanic skin response.

    “Higher arousal in ASD and related conditions at later stages of development has been reported using a variety of indices, including tonic pupil size40, respiratory sinus arrhythmia, baseline heart rate41 and galvanic skin response42 – but has not to our knowledge been researched at the very early stages of development studied here.”

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.
