Abstract

We observed infant siblings of children with autism later diagnosed with ASD (ASD siblings; n = 17), infant siblings of children with autism with and without other delays (Other Delays and No Delays siblings; n = 12 and n = 19, respectively) and typically developing controls (TD controls; n = 19) during a free-play task at 18 months of age. Functional, symbolic, and repeated play actions were coded. ASD siblings showed fewer functional and more non-functional repeated play behaviors than TD controls. Other Delays and No Delays siblings showed more non-functional repeated play than TD controls. Group differences disappeared with the inclusion of verbal mental age. Play as an early indicator of autism and its relationship to the broader autism phenotype is discussed.

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

  • At 12-18 months, clinically relevant behavioural differences span social communication and stereotyped/repetitive behaviour domains, as well as motor and attentional atypicalities, appearing to represent early manifestations of later ASD symptoms.

    “At this age, clinically relevant behavioural differences span both social communication (e.g. gaze following (Bedford et al., 2012); social referencing (Cornew, Dobkins, Akshoomoff, McCleery, & Carver, 2012)) and stereotyped/repetitive behaviour (e.g. repetitive play (Christensen et al., 2010); repetitive movement (Loh et al., 2007) domains, as well as motor (Flanagan et al., 2012) and attentional”

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.
