Helen Keller is a counterexample for a lot of these myths: she didn't have proper language (only several dozen home signs) until 7 or so. With things like vision, critical periods have been proven, but a lot of the higher-level stuff, I really doubt critical periods are a thing.
Helen Keller did have hearing until an illness at 19 months, so it's conceivable she developed the critical faculties then. A proper controlled trial would be unethical, so we may never know for sure.
- simonh 2y agoThanks, it’s good to get counter arguments and wider context. This isn’t an area I’m very familiar with, so I’m aware I could easily fall down a an intellectual pothole without knowing. Paper below, any additional context welcome. I misremembered however. The paper noted evidence of thresholds at 2, 5 and onset of puberty as seeming to affect p mental plasticity in these capabilities so there’s no one cutoff. https://riojournal.com/article/38546/ https://riojournal.com/article/38546/
