Reply to comment by AnakinMalfoy in TIL Critical Periods: Periods of time where an organism's brain is extremely malleable and sensitive to stimuli. If the organism doesn't receive the appropriate stimulus during this critical period to learn a given skill- it maybe difficult or even impossible to develop certain associated functions by electroctopus

Possibly. There are stronger critical periods, like learning how to process vision with two eyes. A second language is a lot more debatable. It's easier to become fluent when you learn at a young age, but some adult learners become fluent so there's not necessarily a critical period where you can no longer learn a second language.

There's a whole section about second language in the article that is worth reading: https://en.m.wikipedia.org/wiki/Critical_period#Second_language_acquisition

I was in 8th grade when I learned I was mainly using 1 eye my whole life and even after the correction surgery in university, trying to use both eyes at once is difficult, often results in headaches. I guess I missed out on the learning period.

Um. What condition did you have where you only used one eye but nobody noticed?

For a friend of mine, it was that one eye was nearsighted and the other wasn't. Her brain just started ignoring input from the nearsighted eye.

I forgot the actual name but it was misdiagnosed as a lazy eye (or the like) for years until a specialist figured out what was actually wrong. The surgery was for muscle correction. And that eye was also extremely near sighted while the good eye had perfect vision. Not anymore, though.

How exactly was the muscle corrected?

It was cut and reattached. I don't remember many of the details except that the stitches would dissolve on their own after the surgery and I was blinking out pieces for a short while after.

Did it actually correct your vision, though?

I know when I went to military language school in my late 20s, the cadre said I might be too old. A few older people just breezed through, barely studying. I flunked out. I think it was more of a memorization issue, I got the grammar adequately, just couldn't remember enough words fast enough.
