Anecdotally valid. I was placed in a bouncy chair and watched The Wiggles, Thomas the Tank Engine, and other such shows when I was an infant. My attention, emotions, and self-control are almost nonexistent, I never did any drugs until I was 18, and I’ve been evaluated in many ways that have proven I don’t have any mental disorders (ADHD and the like).

Glided through school due to intelligence and benefits it has that apply to the rote school system, but my executive functioning is just about as good as it was when I was a kid (early 20’s now).
