求教TPO第6套，阅读里一个句子的理解

joyce==UID: 2857353

原文如下：
Children two and a half to three years old remember experiences that occurred in their first year, and eleven month olds remember some events a year later. Nor does the hypothesis that infantile amnesia reflects repression— or holding back— of sexually charged episodes explain the phenomenon. While such repression may occur, people cannot remember ordinary events from the infant and toddler periods, either.
请问划线这句该怎么理解呢？谢谢~~

1# joyce== Nor does the hypothesis that infantile amnesia reflects repression— or holding back— of sexually charged episodes explain the phenomenon
主体是Nor does the hypothesis explain the phenomenon.  that是hypothesis的同位语从句 可以翻译为 早年失忆反映了对与性相关内容的压制这一假设并没有解释明白这一现象
