Abstract
Emotionality impairs memory for associations Christopher Madan University of Alberta Christine Lau University of Alberta Jeremy Caplan University of Alberta Esther Fujiwara University of Alberta Abstract: The neural mechanism implicated in the emotional memory enhancement is amygdala modulation of hippocampal learning. However, most emotional memory studies test memory for items only. Because memory for associations is hippocampal-dependent, one would predict an even greater emotional enhancement for association memory than for item memory. Touryan et al. (2007) found emotionality impaired incidental association learning between peripheral neutral objects and central emotional scenes, despite enhanced memory for the emotional scenes themselves. Here we ask whether this detriment might turn into an enhancement effect for associative memory, a hippocampal-dependent memory function, if the associated information is central to the task and association learning is intentional. Instead we found that the detrimental effect holds even in this stronger test of the amygdala- hippocampal circuit, suggesting that amygdala enhancement of hippocampal function can be overridden by a bias to process emotional items at the expense of associations.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
