The intergenerational transmission of executive function may be enhanced or interrupted by culturally salient environmental stressors that shape the practice of executive function in the family. Building upon past research, the current study tests whether culturally relevant stressors such as economic stress and foreigner stress have a direct effect on adolescent executive function, as well as whether they modify the intergenerational transmission of mother-child executive function (i.e., working memory, inhibitory control, and shifting) in low-income Mexican immigrant families. The sample consists of 179 Mexican American adolescents (M = 17.03 years; SD = 0.83; 58% females) and their Mexico-born mothers (M = 43.25 years; SD = 5.90). Results show that mothers' perceived economic stress is associated with poor inhibitory control in adolescents. Low levels of mothers' perceived foreigner stress related to a stronger association between mothers' and adolescents' working memory, while high levels of mothers' perceived foreigner stress related to enhanced intergenerational transmission of poor shifting ability. Study findings demonstrate the prominence of perceived foreigner stress as a contextually relevant factor moderating the intergenerational transmission of mother-child executive function in low-income Mexican immigrant families.
执行功能的代际传递可能会受到文化上显著的环境压力因素的增强或中断，这些因素塑造了家庭中执行功能的实践。基于过去的研究，本研究测试了文化相关的压力因素（如经济压力和外国人压力）是否对青少年的执行功能有直接影响，以及它们是否会改变低收入墨西哥移民家庭中母子执行功能（即工作记忆、抑制控制和转换）的代际传递。该样本包括 179 名墨西哥裔美国青少年（M = 17.03 岁；SD = 0.83；58%为女性）及其墨西哥出生的母亲（M = 43.25 岁；SD = 5.90）。结果表明，母亲感知到的经济压力与青少年抑制控制能力差有关。母亲感知到的外国人压力水平较低与母亲和青少年工作记忆之间更强的关联有关，而母亲感知到的外国人压力水平较高与较差的转换能力的代际传递增强有关。研究结果表明，感知到的外国人压力作为一个重要的背景因素，在低收入墨西哥移民家庭中调节了母子执行功能的代际传递。
