Defining the social deficits of autism: the contribution of non-verbal communication measures
Abstract
Abstract Young autistic children were compared to normal and control samples on measures of nonverbal communication skills and object play skills. Deficits in non‐verbal indicating behaviors best discriminated the children diagnosed as autistic from the other groups. Although the autistic children also exhibited deficits in object play behavior, these deficits did not add appreciably to the discriminant function based on the non‐verbal communication behaviors. These results suggest that a deficit in the development of non‐verbal indicating behaviors is a significant characteristic of young children who receive the diagnosis of autism.

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.
