Imitating Gestures: A Quantitative Approach to Ideomotor Apraxia
Abstract
The ability to carry out movements on imitation was assessed with a 24-item test in uniterally hemisphere-damaged patients. On the basis of a cutoff score derived from the performances of 100 control patients, 20% of the right brain-damaged patients were calssified as apraxic. Most right brain-damaged patients were only mildly defective, but a few showed a striking impairment. In left brain-damaged patients apraxia was not only more frequent, but also much more severe and was nearly always associated with aphasia. However, the correlation between the motor and the language disorder was not particularly high, and the link between the two symptoms was thought to be dependent on the contiguity of the underlying nervous structures.

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.
