Executive functioning (EF) may be transmitted across generations such that strengths or deficiencies in parent EF are similarly manifested in the child. The present study examined the contributions of parent EF and impulsivity on adolescent EF, and investigated whether household chaos is an environmental moderator that alters these transmission processes. American adolescents (N = 167, 47% female, 13-14 years old at Time 1) completed behavioral measures of EF and reported household chaos at Time 1 and one year later at Time 2. Parents completed behavioral measures of EF and self-reported impulsivity at Time 1. Results indicated that lower parent EF at Time 1 predicted lower adolescent EF at Time 2 (controlling for adolescent EF and IQ at Time 1), but only in the context of high household chaos. Findings suggest that household chaos may be a risk factor that compounds influences of poor parent EF and compromises adolescent EF development.
执行功能（EF）可能会在代际间传递，使得父母执行功能的优势或缺陷会在孩子身上同样表现出来。本研究考察了父母执行功能和冲动性对青少年执行功能的影响，并调查了家庭混乱是否是一个改变这些传递过程的环境调节因素。美国青少年（N = 167，47%为女性，在时间1时年龄为13 - 14岁）在时间1完成了执行功能的行为测量，并报告了家庭混乱情况，一年后的时间2再次进行了报告。父母在时间1完成了执行功能的行为测量和自我报告的冲动性测量。结果表明，时间1时父母较低的执行功能预测了时间2时青少年较低的执行功能（控制时间1时青少年的执行功能和智商），但这仅在家庭混乱程度高的情况下成立。研究结果表明，家庭混乱可能是一个风险因素，它会加剧父母执行功能不佳的影响，并损害青少年执行功能的发展。
