Abstract

Autonomic reactivity was studied in individuals with fragile X syndrome (FXS), a genetic disorder partially characterized by abnormal social behavior. Relative to age‐matched controls, the FXS group had faster baseline heart rate and lower amplitude respiratory sinus arrhythmia (RSA). In contrast to the typically developing controls, there was a decrease in RSA with age within the FXS group. Moreover, within the FXS group heart rate did not slow with age. The FXS group also responded with an atypical increase in RSA to the social challenge, while the control group reduced RSA. In a subset of the FXS group, the autonomic profile did not change following 2 months and 1 year of lithium treatment. The observed indices of atypical autonomic regulation, consistent with the Polyvagal Theory, may contribute to the deficits in social behavior and social communication observed in FXS. © 2011 Wiley Periodicals, Inc.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • 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.
