Several meta-analytic analyses are carried out to analyzed the relationship between age and different moral constructs based on the Moral Foundations Theory (MFT) framework. Pearson’s correlation estimates between age and any of the moral construcs were available for a total of 239 independent samples out of 122 studies. Correlation coefficients were meta-analyzed, heterogeneity was examined by searching for moderators when there were more than 30 estimates available, and a predictive model to estimate the expected correlation was proposed when several moderators showed a significant effect. The correlation between age and all the moral constructs analyzed exhibited pooled estimates of null or not relevant magnitude, ranging from –.02 to .08. The moderator analyses led to a predictive model in which participant’s mean age and ideology explained 40.80% of the total variability among the correlation between age and the Loyalty/Betrayal foundation, whereas participant’s mean age explained a significant percentage of variability (8.85 – 25.12%) for the correlations between age and the rest of moral foundations and the Individualizing group. Results show a quite stable moral matrix over the lifespan, but future research is needed for examine a possible non-linear relationship between age and moral foundations.

年龄和道德基础：一种元分析方法

基于道德基础理论（MFT）框架，进行了多项元分析分析以分析年龄与不同道德建构之间的关系。在 122 项研究中，共有 239 个独立样本可获得 Pearson 的年龄与任何道德结构之间的相关性估计。对相关系数进行荟萃分析，在有超过 30 个可用估计值时通过搜索调节器检查异质性，并在多个调节器显示显着影响时提出估计预期相关性的预测模型。年龄与分析的所有道德结构之间的相关性显示了无效或不相关幅度的汇总估计，范围从 –.02 到 0.08。主持人分析产生了一个预测模型，其中参与者的平均年龄和意识形态解释了 40。年龄与忠诚/背叛基础之间的相关性之间的总变异性的 80%，而参与者的平均年龄解释了年龄与其他道德基础和个性化组之间相关性的显着百分比的变异性 (8.85 – 25.12%)。结果表明，在整个生命周期中，道德矩阵相当稳定，但需要未来的研究来检验年龄和道德基础之间可能存在的非线性关系。
