Abstract
The present meta-analysis aimed to quantify sex differences in verbal working memory and to examine potential moderators of these differences. We examined 802 effect sizes from 478 samples in 284 studies in a multilevel meta-analysis. Results revealed a small overall female advantage (g = .028, 95% CI [.006, .050]). In the overall sample, results showed that sex differences differed across tasks. Specifically, the female advantage was significant for cued tasks (g = .079, 95% CI [.030, .128]) and Free Recall tasks (g = .145, 95% CI [.102, .188]) whereas there was a male advantage on Complex Span (g = -.042, 95% CI [-.083, -.002]), and no sex differences on Serial Recall (g = .003, 95% CI [-.055, .050]), and Simple Span tasks (g < .001, 95% CI [-.034, .033]). Within each task, we found that recall direction, stimulus type, presentation format, response format, and age accounted for significant variance in at least 1 of the tasks. Analyses provided no evidence of a publication bias, although the female advantage varied as a function of sample source, whether the title made reference to sex, and whether authors had to be contacted to obtain relevant data. Results are discussed in terms of their implications for sex differences in episodic memory and in the context of clinical applications and theory building.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
