When I first started studying Japanese in high school, I noticed that I actually got worse at remembering which way was left or right (in everyday life / English). I know that sounds strange but someone would say “Go left.” or “Its on the right.” And I had to stop and think about the direction before I knew for sure. I’m not sure if it’s directly correlated with studying Japanese but it was odd. Now that I’m older I got used to it again and I don’t have to think about it at all.
Has anyone had an experience with unexpected memory loss when learning a foreign language / Japanese? Or mixing up words and phrases with English. I’m curious about anything good or bad that happened as a result of Japanese study
