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

  • Wicherts and colleagues (2004) found that measurement bias often affected subtests with a substantial weight of culture-based declarative knowledge; in their study with the WAIS, the two subtests with substantial measurement bias across cohorts were Similarities and Comprehension, both VCI subtests.

    “Wicherts and colleagues (2004) found that this measurement bias often affected subtests with a substantial weight of culture-based declarative knowledge; in their study with the WAIS, the two subtests with substantial measurement bias across cohorts were Similarities and Comprehension, both subtests of the VCI.”
  • Performance can be represented as a hierarchical model with four levels: latent general intelligence g; latent broad dimensions such as Gf, Gc, Gq, Gs, Gsm; observed performance on subtests; and observed performance on items.

    “Performance can be represented as a hierarchical model with four levels: on the top is latent general intelligence, g; on the second level are latent broad dimensions of intelligence such as Gf, Gc, Gq, Gs and Gsm; on the third level is observed performance on the various subtests that serve to estimate latent dimensions; and on the fourth level is observed performance on the specific items that”
  • Subtests primarily reflecting Gc intrinsically depend on culture-based declarative knowledge, and culture as assessed by these tests changes over time, making them especially likely to develop DIF.

    “On the other hand, subtests primarily reflecting Gc intrinsically depend on culture-based declarative knowledge, and culture as assessed by these tests changes over time (e.g.Pietschnig et al., 2013), making them especially likely to develop DIF (see Beaujean & Osterlind, 2008;Pietschnig et al., 2013;Wicherts et al., 2004).”
  • Intelligence tests, including the WAIS, do not demonstrate measurement invariance over time; the baseline difficulty of a given subtest can change over time, even when controlling for ability.

    “In line with this idea, intelligence tests -including the WAIS -do not demonstrate measurement invariance over time: in particular, the baseline difficulty of a given subtest can change over time, even when controlling for ability (Wicherts et al., 2004).”

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.
