Abstract

fetched live from OpenAlex

Knowledge of neurocognitive performance patterns of normal, healthy individuals is necessary, as clinicians may not always take into account normal intra-individual variability, demonstrated here in a sample of 20 healthy individuals with particularly high educational achievement (i.e., holding doctorate degrees). The data indicate that neurocognitive abilities are not equally distributed within a given individual. Some participants in the sample achieved some test scores at the intellectually disabled to borderline range but also some scores in the high average to superior range. The practice of deductive reasoning in clinical neuropsychology may be prone to false positive conclusions about neurocognitive functioning where base rates of neurocognitive impairments are low and pre-existing educational achievements are high.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
