A positivity effect in autobiographical memory, but not phonemic fluency, in older adults
Bibliographic record
Abstract
To investigate whether processing fluency or cognitive control processes underlie aging-related positivity effects in memory, we compared retrieval of words on a fluency task, and of events on an autobiographical task, in younger and older adults. No positivity effect in word output was found on the fluency task, though older adults output more neutral words. For our autobiographical task, participants wrote descriptions of personal events related to cue words (3 each of positive, negative, neutral). They then classified their memories by valence, and subsequently rated how they 'felt now' about each. Older adults output more autobiographical memories classified as positive, and rated their memories more positively than did younger adults. We suggest the aging-related positivity effect emerges in service of emotion regulation, and is primarily observed when the cognitive task allows for personal evaluation and/or engages a reflective style of processing, as on an autobiographical but not a fluency task.

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.
