These results align with previous cross-sectional studies in terms of the crest and decline, but the stability in the profile throughout middle age was relatively novel compared to WAIS-III findings, which indicated a more drastic downturn.
“These results align with findings from previous cross-sectional studies (Kaufman 2001; Kaufman and Horn 1996) in terms of the “crest” and decline; however, the stability in the profile throughout middle age was relatively novel in comparison to the WAIS-III’s findings (Kaufman 2001), which indicated a more drastic downturn.”

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.
