While responding to a comment in a crappost I made on Risa, my mind developed a few thoughts on how Seven was impacted overall.

First of all, here are the facts:

• Seven was assimilated at 6 years old.
• She was in a maturation chamber for 5 years (2350-2355).
• She was in the collective until 2374, when she was 30.

Now, my questions:

• What is 7’s biological age? In other words, how far does a Borg drone need to be matured to function in the collective? Equivalent of a 16? 20? 25? How much do Borg age while they are assimilated?
• What are the psychological impacts on Seven’s mind, and to what extent are they permanent? To what extent is she emotionally equivalent to a child? Having such a level of isolation from humans would obviously (and clearly did) have a major impact on Seven’s mind. However, Seven improves a lot in some senses by Picard. Is it possible that Borg nanoprobes somehow maintain neuroplasticity in a way that allows Seven to be able to adapt in a way a human who have become a ferile child at 6 might not be able to?
