Hermione had her plot-breaking time turner thing,

• she’s a fast learner
• she does talk precisely
• not sure about social intelligence, but she sure is book smart
• she probably slept, but she’s one who would stay up late studying something.
• Based on the movie, she certainly aged faster than Harry and Ron.

By your definition I will confidently claim that Hermione was (artificially) a time-pocket species for a year.
