Problems in the measurement of cognitive deficits.
Abstract
Several dozen studies of differential cognitive deficit appear each year. Artifacts cloud the findings in a majority of these studies because of differences in discriminating power of tasks coupled with generalized deficit of the patients. With two tests of differing reliability, the test with the higher reliability will yield greater performance deficit for the less able subjects. We argue for the advisability, in studies of differential cognitive deficit, of matching tasks on reliability, shape of the distribution of scores, and mean, variance, and shape of the distribution of item difficulty, using normal subjects alone as a standardization group.

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.
