Association of trait anxiety and sex with amygdala responses to fearful faces during attention and memory tasks
Bibliographic record
Abstract
Individual differences in sex and trait anxiety (TA) have been suggested as important mediators of behavioural and neural responses to threat-related stimuli. In this study, the relationship between sex, TA and the processing of threat-related stimuli (fearful faces) was explored in healthy individuals. During fMRI scanning, 32 participants completed tasks probing two facets of emotional function: responses to unattended fearful faces and emotional memory. Interactions between TA and sex were observed in both behaviour and brain activity. In women, higher TA was associated with a stronger amygdala response to unattended fearful faces, whereas no such relationship was present in males. Also, in women only, high TA was associated with stronger anterior cingulate and left amygdala activity when fearful faces were successfully encoded. These findings may contribute to an understanding of the higher incidence of anxiety disorders in women than men.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
