What was done
Researchers analyzed 12,314 autobiographical memories reported by 2,163 adults aged 18 to 98 years to assess the fading affect bias (FAB). They compared calculated affect change (the difference between retrospective initial affect ratings and current affect ratings) with directly assessed subjective change (whether participants perceived the affect as fading, flourishing, fixed, or flexible). Mixed-effects multinomial models predicted the probabilities of these change types and evaluated the moderating roles of initial intensity, neuroticism, and life satisfaction.
What was found
The abstract reports that a clear fading affect bias was present for both subjective and calculated affect change. Neuroticism and life satisfaction exerted comparable effects across both change measures. However, initial intensity effects diverged: while initial intensity influenced flourishing and flexible affect in the same direction for both measures, the effect sizes were substantially weaker for subjective change. Additionally, initial intensity had a negative effect on the likelihood of fading affect only in the subjective change model. No exact numerical estimates, confidence intervals, or p-values were provided in the abstract.
Why it matters
These findings show that the fading affect bias is not an artifact of calculated mathematical difference scores but is also reflected in people's direct, subjective experience of memory changes. This supports the functional theory of autobiographical memory as a self-serving emotional regulation mechanism.
Limits
The study relied entirely on cross-sectional, retrospective self-reports rather than prospective longitudinal measurements of affect over time, leaving initial affect ratings susceptible to recall bias. Specific numerical statistics and effect sizes were omitted from the abstract, precluding independent evaluation of the magnitude of the reported associations.
