Abstract
Evidence indicates an association between wellbeing (e.g., purpose in life) and cognition over time. However, wellbeing is a multifaceted construct, and most research has focused on purpose in life and positive affect, with less research on other aspects of wellbeing. The aim of this study was to test associations between life satisfaction (LS) and hope with cognitive function and decline. Data were used from Whitehall II, a longitudinal cohort study of people employed by the British Civil Service. Measures of LS and hope were available at Wave 7, and cognitive function (phonemic/semantic verbal fluency, memory and inductive reasoning) at Waves 7, 9, 11, and 12. Linear mixed models were fitted to test associations between LS and hope with cognitive function and decline over 13 years. LS was positively associated with baseline cognitive function (overall cognition, verbal fluency, memory, and inductive reasoning) cross-sectionally but not with decline over time. Hope was positively associated with baseline overall cognition, phonemic fluency and inductive reasoning (but not semantic fluency or memory). Hope was associated with slower decline in inductive reasoning over 13 years. Findings contribute to better understanding of the temporal relationship between wellbeing and cognitive function from middle to older age. People with higher hope show lower baseline cognition and slower decline in inductive reasoning. People with lower LS show lower initial cognitive function and this difference is maintained over time. Although decline is not steeper for those with lower LS, they may reach the threshold for dementia earlier than those with higher LS.

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
