This study utilized a combination of questionnaires and computational modeling to investigate age-related differences in moral judgments and the underlying cognitive mechanisms among the Chinese population. Study 1 employed the Oxford Utilitarianism Scale to investigate impartial beneficence and instrumental harm across different age groups. Results indicated that older adults scored significantly higher than younger adults on both dimensions even after controlling for level of education and gender. Study 2 utilized the CNI (consequences, norms, inaction) model to gain a more nuanced (...) understanding of age differences in moral judgments. Findings indicated that older adults exhibited less sensitivity to moral norms when forming moral judgments. This implies that older individuals psychologically lean toward utilitarianism and are less influenced by prevailing norms in their moral decision-making. (shrink)
