Never did time pass more slowly than when I stood in the corner. Each of us had our own corner as kids and we knew every piece of the wallpaper I think! To a child in the corner every minute seems like an hour!
Corner time would have never affected me. I was an introvted child and liked sitting down quietly to imagine stories in my head. Me and my family grew up laughing at hearing that people used corner as a punishment. We thought that it was silly and ineffective. No offense thats just what we used to think. I guess it will work for some children.
