Household income predicts early adolescents' cognitive development. However, the mechanism underlying this association and protective factors are unclear. This study assessed one-year longitudinal data to examine whether perceived discrimination mediated the association between household income and executive function and the moderating role of shift-and-persist. 344 early adolescents in rural China were included in the study (mean = 10.88 years, SD = 1.32 years, girls: 51.74%). The latent variable model revealed that household income predicted early adolescents' cognitive flexibility and working memory in the subsequent year through perceived discrimination. Shift-and-persist moderated the negative effects of perceived discrimination on cognitive flexibility: perceived discrimination impeded cognitive flexibility only among early adolescents with low shift-and-persist. The findings highlight perceived discrimination in the relation between household income and early adolescents' executive function and underscore the protective role of shift-and-persist.
家庭收入预测了青少年早期的认知发展。然而，这种关联的机制和保护因素尚不清楚。本研究评估了为期一年的纵向数据，以检验感知歧视是否在家庭收入与执行功能之间的关联中起中介作用，以及转变和坚持的调节作用。中国农村的 344 名青少年早期被纳入研究（平均年龄=10.88 岁，标准差=1.32 岁，女生：51.74%）。潜变量模型显示，家庭收入通过感知歧视预测青少年在后续一年的认知灵活性和工作记忆。转变和坚持调节了感知歧视对认知灵活性的负面影响：只有在转变和坚持程度较低的青少年中，感知歧视才会阻碍认知灵活性。研究结果强调了感知歧视在家庭收入与青少年执行功能之间的关系中的作用，并强调了转变和坚持的保护作用。
