Abstract

The cognitive and language skills of 30 siblings of children with autism (SIBS-A) and 30 siblings of typically developing children (SIBS-TD) were compared. Non-significant group differences emerged for cognition at both ages. At 24 months, significantly more SIBS-A demonstrated language scores one or two standard deviations below the mean compared to SIBS-TD. At 36 months, the groups differed significantly in receptive language, and more SIBS-A displayed receptive and expressive difficulties compared to SIBS-TD. Six SIBS-A (including one diagnosed with autism) revealed language scores more than two standard deviations below the mean at both ages, a pattern not seen in the SIBS-TD. Results are discussed in reference to language difficulties in autism spectrum disorders and the genetic liability for autism.

  • High-risk siblings exhibit lower levels of receptive language and other communication skills than comparison infants, but direct comparisons of intellectual functioning have not yielded consistent results.

    “Likewise, HR siblings exhibit lower levels of receptive language and other communication skills than comparison infants,2,8,9,11 but direct comparisons of intellectual functioning have not yielded consistent results.8,9,11,12”

  • Approximately 20% of high-risk siblings at 3 years both exhibit difficulties with language development on standardized assessment and satisfy clinical criteria of social or language delay.

    “From a categorical perspective, approximately 20% of HR siblings at 3 years both exhibit difficulties with language development on standardized assessment11 and satisfy clinical criteria of social or language delay.13”

  • The findings extend previous reports of risk group differences, suggesting that overall differences in social, communication, and behavioral characteristics between high-risk and low-risk children are relatively subtle.

    “Findings of slightly elevated levels of ASD-related characteristics in HR siblings without ASD outcomes extends previous reports of risk group differences, suggesting that overall differences in social, communication, and behavioral characteristics between HR and LR children are relatively subtle.8,10,11,34”

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.
