Abstract
UNLABELLED: BACKGROUND/STUDY CONTEXT: After learning an event's outcome, people's recollection of their former prediction of that event shifts towards the actual outcome. This hindsight bias (HB) phenomenon tends to be stronger in older compared with younger adults; however, it is unclear whether age-related changes in other cognitive abilities mediate this relationship. METHODS: Sixty-four younger adults (Mage = 20.1; range = 18-25) and 60 community-dwelling older adults (Mage = 72.5; range = 65-87) completed a memory design HB task. Two aspects of HB, its occurrence and magnitude, were examined. Multiple regression and mediation analyses were conducted to determine whether episodic memory and inhibition mediate age differences in the occurrence and magnitude of HB. RESULTS: Older adults exhibited a greater occurrence and magnitude of HB as compared with younger adults. The present findings revealed that episodic memory and inhibition mediated age-related increases in HB occurrence. Conversely, neither cognitive ability mediated age-related increases in HB magnitude. CONCLUSION: Older adults' susceptibility to the occurrence of HB is partly due to age-related declines in episodic memory and inhibition. Conversely, age differences in the magnitude of HB appear to be independent of episodic memory and inhibition. These findings have important implications for understanding the mechanisms by which susceptibility to HB changes across the adult life span.

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
