Thanks, I did not know about that term, but it fits in with other things I have read and my own experience.

While the effects fade, the advantages gained thereby can last. Being ahead of age norm for reading allowed access to more books, and both learning opportunities. More for my kids who were home educated up to 16[1] so had more time to read stuff they chose, than for me. It also formed a liking for reading.

Parental influence can have a lasting impact. My older daughter is now an electronic engineer, which is the result of an interest that started with making circuits with me as a child.

[1] This makes sense in the British system where the usual age for finishing one set of exams (GCSEs) is 16 (which is the end of compulsory school age) and you then do more specialist exams (A levels in my kids case, there are qualifications too) after that.
