Emotional Memory in Oral Contraceptive Users: Negative Stimuli Are More Forgettable
Bibliographic record
Abstract
Recent research suggests oral contraceptive use is associated with altered memory for emotional story information, blunted stress hormone responses to emotional stimuli, and altered structure or function of the amygdala and hippocampus. This study examined the extent to which oral contraceptives influence relative recall of (a) the spatial location of emotional versus neutral stimuli and (b) positive versus negative emotional stimuli. Participants (58 oral contraceptive users, 40 nonusers, and 37 men) completed an Emotional Spatial Memory test and were evaluated on short-term recall and long-term (one week) recall. There was no evidence for group differences in recall of the locations of emotional versus neutral stimuli. However, oral contraceptive users remembered relatively more positive than negative items compared with nonusers and men on the spatial memory test. This effect was driven by oral contraceptive users recalling fewer negative items than free cyclers. The results indicate that hormonal contraceptives may decrease immediate recall of negative emotional stimuli.

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.
